Claims. (01. 112-191) This invention relates to sewing vmechines, and particularly to an improved sewing machine adapted to sew a binding on a carpet or rug, an object being to provide a construction which will sew the binding in place by a seam extending diagonally through the base of the rug to the rear surface thereof and also through two parts of the binding.-

Another object of the "invention is to provide a sewing machine for securing bindings on rugs, carpets and the like wherein means are provided for completing a preliminary sewing of a binding or presenting an original retaining seam for a the binding. 15 I An additional object is to provide a sewing machine uitilizing a needle and a looper operating in planes at right angles to each. other for presenting a diagonal seam extending through two sections of the binding for holding one section along the edge of the base and the other section on the bottom of the base.

Referring to the accompanying drawings by numerals, l indicates a casing of metal or other material which encloses most of the working parts. This casing may have, if desired, a metal bottom 2 as shown in Fig. 6, and to this bottom 25 may be connectedqasters 3 whereby the device may be rolled along the rug or carpet as the same is used. It will be understood that the device may be moved along the mg or carpet or the carpetmay be moved along the device. Inorder that the needle shall function properly arelative movement of the rug and device must take place and this is regulated more or less by the operator as he pulls the device along.

As shown in Fig. 6, there is provided a platform 8 which may be bolted or otherwise rigidly secured to the base 2 and which supports a small portion of the rug 5. It is to be understood that the rug 5 is inverted when the binding 6 is to be applied so that the base 1 will be upperrnost and the pile 8 will be facing downwardly.

In placing the binding 6 in position it is fed by any suitable feeding means so that a large section 9 will'rest against the bottom surface of the base i and a folded edge ill will rest against the edge of the base 1 as clearly shown in Fig. 10. It is of course evident that instead or folding the. edge in it could be left straight or unfolded as shown in Fig. 19. The tape may be fed by hand into position or automatic feeding means may be provided as disclosed in my copending application Serial No. 75,058.

Referring particularly to Fig. 3, it will be observed that there is provided what may be termed a. vertical needle ll anda horizontal looper I2.

The needle II moves back and forth in a vertical plane and the looper I2 moves back and forth in a horizontal plane, and the needle and looper move and dwell at different points to pro-' duce the desired loops and stitching as illustrated in Figs. to 19 inclusive. From Fig. 3 it will be observed that the looper I2 is secured by a set screw I3 to an arm I4 of lever l5. As illustrated in Fig. 8, looper I2 is provided with a 10 groove [4' so that the thread l6 may extend throughthearm I4 tothe eye I! andthenbackto form the desired loop. Lever I! as shown in Fig. 3 is pivotally mounted on bracket I6 by a suitable pivotal pin or screw l6. Bracket I6 is screwed to the casing I and is held rigidly in place. Arm I4 is provided with a slot 26 which accommodates the pin 2| carried by lever 22. Lever 22 is provided with a pin 22 extending into the cam groove 24 of the cam 25 so that as cam 26 moves lever 22 will swing back and forth in the order as indicated in Fig. 20.

Cam is rigidly secured to a power shaft 26 which extends outwardly through the casing I and is connected to an electric motor or other 25 power means which preferably is rotating shaft 26 at a constant speed during the functioning of the device. Also rigidly secured to the shaft 26 is a cam wheel 21 which has a cam groove 26 which accommodates the pin 26 carriedby the 30 reciprocating bar 26. Bar 36 is slidably mounted in a suitable bearing structure 3| and has a pin 32 (Fig. 6) at the outer end extending through the slot 32 of the short lever 34 which is keyed or otherwise rigidly secured to the rock shaft 25.

35 Shaft 36 is mounted in suitable journal members 26 and 21 carried by the bottom 2 of the casing. It will therefore be seen that as shaft 26 rotates, rock shaft 35 will be rocked back and forth but the movement will be according to the shape of 0 the cam 26 which is shown in diagram in Fig. 20 and which causes the needle to move back and forth but dwell at different points of its movement.

Needle II is rigidly secured-by a set screw or other means to a sliding plate 36, which plate has an encircling member I! encircling arm 40. The encircling member 36 is slidabie along the arm 46 but normally is rigidly clamped thereto by a set screw 4|. This arrangement permits the needle to be adjusted to move in a lower or higher path to coact properly with the looper. The arm '46 is keyed or otherwise rigidly secured to shaft 35 so as to move therewith. The casing I is cut away at 42 to permit the needle II to move back 5 and .forth as desired. It will be noted that the looper I2 is exteriorly of the casing I at all times and is intended to move horizontally over the binding 6 but not to enter this binding or any part of the rug. The vertical needle II, however, is intended to be thrust through the edge of the rug diagonally fromnear the. top part of thebaseof the rugtothebottomoftherugas illustrated particularly in Fig. 11 of the drawings.

While power is being transmitted to the needle and looper as. just described, power will also be transmitted through pinion 43 to pinion 44 which is rigidly secured to shaft 45 carried by a suitable bearing 46. A cam wheel 41 is also rigidly secured to shaft 45, said cam wheel having a cam groove 48 for accommodating the pin 48 carried by the reciprocating and wcillating rod 60. This rod is .slidably carried by a support 6| having a laterally projecting extension 62 rockably mounted in the bearing box 63 and held in place by the screw 64 whereby the rod 66 is caused to reciprocate as the cam wheel 41 rotates. At the end of rod 66' opposite the cam wheel 41 a pin 65 loosely extends through the rod and is preferably rigidly secured to the sleeve 56, which sleeve is held between enlargements 51 and 66 of an internally threaded member 66 as shown in Fig. 4. A threaded member 66 is screwed into member 69 and in addition is provided with an enlargement 6| which surrounds the end of shaft 62 and which carries a pawl 63 adapted to coact with a ratchet wheel 64. The ratchet wheel 64 is rigidly secured to shaft 62 and upon each reciprocation of the rod 66 thegpawl 62 engages one of the teeth of the ratchet wheel and moves the ratchet wheel a certain distance. By adjusting the member 56 upwardly or downwardly on member 66 as shown in Fig. 4, the amount of movement of ratchet wheel 64 may be determined. In this way shaft-62 is given an intermittent movement during the rotation of the power shaft 26.

Shaft 62 (Fig. 4) is supported by a journal member 66 and in turn supports a sleeve 66 which extends through the journal member 61 and has a pinion 66 rigidly secured thereto. Shaft 62 has a universal joint 66 as shown in Fig. 3 whereby the toothed feeding wheel I0 may be set at an angle, certain parts being supported by the bracket II rigidly secured to castag I. Sleeve 66 carries a gear wheel 12 which continually meshes with the gear wheel I3 rigidly secured to shaft 26 whereby the sleeve 66 will rotate at a greater rate of speed than shaft 82 and by reason of the pinion I4 will drive the toothed wheel I6 at a higher speed than the toothed wheel I6. It will of course be understood that the toothed wheel I6 is rigidly secured to a shaft I6 carried by part of bracket II and this shaft in turn is rigidly secured to gear wheel I4. The toothed wheel Iris positioned to give the part 9 of the binding 6 a tendency to move away from the edge of the rug and thus maintain the binding tight during the stitching operation. The toothed wheelv I0 is intended to assist in feeding the device along the rug while the toothed wheel I6 maintains the binding] taut. It will also be noted from Fig. 6 that the platform 4 is vertically adjustable so as to be movable toward and from the bracket 4'. By this structure rugs of different thicknesses may be taken care of, and also by lowering or raising the platform 4 the needle Il may becaused to place the stitching as shown in Fig. 1'1 or as shown in Fig. 19.

Referring aga n to the needle II, it will be seen from Fig. 'I that the same has been provided with an outside groove II similar to the groove l4 of looper I2. The needle may be fastened into the plate 38 in any desired way. as for instance by the set screw I6. It will also be noted that both the looper I2 and the needle II are formed on an arc and therefore travel back and forth in their different arcsas the machine functions. Attention is called to Fig. 2, from whith it will be observed that the clamping-screws I9 which hold the platform 4 in place extend through suitable slots 86 whereby this platform may be raised and lowered to accommodate rugs of different thicknesses.

When the device is to be used it may be moved along the rug or carpet as it functions or the carpet or rug may be moved past the device.

.Cal

Preferably the device is moved and the rug or carpet is held stationary as the device is comparatively small while the rug is large and heavy. when the rug is first placed in position in the 75 device it will have the end portion resting on the platform 4 and the needles will be positioned as shown in Fig. 10. Power is then turned on so that shaft 26 will begin to rotate and the first 5 movement will be the movement of needle II as it penetrates or is thrust through the edge portion of base 1. This is illustrated in Fig. 11. As shown in Fig. 11 the needle passes immediately below the turned-down portion III of the binding 6, but if desired it could pass through the portion Ill as -illustrated in Fig. 19 which shows this modified arrangement. This result may be secured by moving the platform 4 as shown in Fig. 6 downwardly the desired distance. As the machine continues to function the parts will move from the position shown in Fig. 11 to that shown in Figs. 12, 13, 14, 15 and 16 respectively.

After the needle I I has been thrust into position or moved from the position shown in Fig. 20

loop 81 will be formed. This loop is of ample sizeto readily permit-the looper l2 to be inserted therethrough as shown in Fig. 13, and after this movement of looper l2 needle i I will be withdrawn as illustrated in Fig. 14 and-thus form what may be termed an eye loop 82. After moving to the position shown in Fig. 14, the ma chine is moved a short distance along the rug and then the needle II is again inserted as shown in Fig. 15. The operation then continues as above described, with the result that soon the seam will appear as shown in Fig. 17. This will place a diagonally arranged stitch at the edge of the base of the rug with the binding covering one edge of the base and covering part of the bottom. A single row of loops 83 will be seen at the edge while on the bottom a plurality of loops will be seen interlocked with the eye loops 82. As the machine continues to function this seam is extended along the full side of the rug, and if desired across the ends and on the opposite side. When complete the seam will appear as shown in Fig. 18. p

In Fig. 19 the same seam is presented except that the rug has been lowered somewhat so that the loops 83 will be overlying part of the folded portion In of the binding 6. In applicant's copending application Serial No. 75,058 a binding has been presented inposition with certain forms of stitchingand with the machine embodying the present invention a second seam may be added to complete the securing of the binding in place. If preferred, the seam in applicant's copending application could be omitted and the seam as shown in Fig. 19, for instance, used alone. In either event the binding is held in,

place by a diagonal seam which is out of sight except for the few loops 83 which extend only through the base of the rug and which are substantially covered to a great extent by the pile ,of the rug falling thereover, which is usually the case when hand sewed.

In Fig. 21 a side view of the heel 15 is seen and from this view it will be obs rvd that there is provided a portion 84 which is not supplied with teeth and which will not contact with the binding. The parts are so proportioned that the machine will be moved along the rug atthe time 7 that the portion 84 is adjacent the binding. It will be noted that when the portion 84 is adjacent the bindingthere will be no tension on the rug or on the binding and consequently the machine may be pulled along easily. Power from any suit- 7 able source may be connected to shaft 26 to 10 to that shown in Fig. 11, it is withdrawn 8. short distance as shown in Fig. 12 so that the operate the moving parts, or if preferred a motor could be built into and form partof the machine.
