JOHN SCHUMACHER AND JOSEPH E. SCHUMACHEB, 015 LOS ANGELES, CALIFORNIA.

FEEDING AND SEVERING APPARATUS.

Application filed April 29, 1916.

T 0 all whom it may concern:

Be it known that We, JOHN SCHUMACIIER and Josnrn E. SCHUMACHER, both citizens of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have jointly invented new and useful Improvements in Feeding and Severing Apparatus, of which the following is a specification.

This invention relates to feeding and severing apparatus, or apparatus in which a product is formed or treated upon the continuous supply of the component parts or substances thereof, or of materials or sub-' stances for treating other materials or substances likewise supplied or fed and severed.

More particularly the apparatus is adapted for the manufacture of plasterboard and similar substances, for which purpose one or more sheets of paper or the like is or are fed continuiiiisly from a roll or rolls of the same, a plastic or like material being deposited upon or between such sheets, the resultant product in finished or partly finished form and condition being subdivided into predetermined lengths or into units of predetermined size and shape.

A particular feature of the present invention consists of means for so subdividing the product as it is continuously formed, or treated and advanced, whereby such product may be so subdivided in the advance or movement thereof, and without interference with the means for causing such advance or necessitating cessation of the movement thereof. Apparatus of this general character is disclosed in another application for United States Letters Patent filed by us jointly April 23rd, 1915, Serial No. 23,521, for apparatus for making plaster board. and the like, and similar apparatus is disclosed in United States Letters Patent No. 1,176,- 322, issued jointly to us March 21st, 1916, for process of making plaster board and the like.

The invention has for particular objects the provision of apparatus or'mechanism generally organized and characterized as above set forth, and which will be superior in point of relative simplicity and relative inexpensivcness of construction and formation, convenience and positiveness and efficiency in service and durability. and which will be generally superior in efficiency and Specification of Letters Patent.

adaptability 'for varying kinds and conditions of service.

lVith the above and other objects in view, the invention consists in the novel and useful provision, formation, construction, combination, association and relative arrangement and mode of application of parts, members and features, all as hereinafter described, shown in the drawing and finally pointed out in claims.

In the drawing: Figure 1 is an isometric view, broken away for fullness of illustration, of mechanism or apparatus organized in accordance with and for the practice of the invention, and specifically devised for the purpose of building up or forming a product comprising strips or sheets of paper or other flexible material and an interposed body of plastic or other material, in accordance with the general constitution of plasterboard as made by the apparatus and following the process of our other said application and our said issued Letters Patent; and, Fig. 2 is an isometric view of a cutter shown in operative position in Fig. 1, the same being shown in Fig. 2 in detached position, and constituting an important feature of the improvements constituting the present invention.

Corresponding parts in both figures are designated by the same reference characters.

Referring with particularity to the drawtable B in Fig. 1, are therein indicated as in process of formation, the upper surface member 3 of each unit A being produced from a continuously fed sheet of paper 6 supplied from a roller 7, the lower surface member l of each such unit A being shown as produced from a continuouslyfed sheet 8 of paper fed from a roller 9, and the body portion of each such unit A being shown as produced from suitable plastic material 10 fed downwardly upon the continuously fed sheet 8 from a hopper 11. The sheet 8 is shown as fedfrom the roller 9 ontoan endless belt conveyer 12 operated by and trained about horizontal spaced rollers 13 journaled at their ends as at 14 in a suitable horizontal frame 15. The'roller 7 is supported above the endless belt conveyer 12 by an upright frame member 16 which. likewise is branched out to support the hopper 11, and furthermore supports a loosely journaled 'compression roller 17 which bears downwardly upon the paper sheet 6 drawn from the roller 7 to compress between such sheet 6 and the lower sheet 8 the plastic material 10 whichp is sandwiched between such sheets, as clearly shown in Fig. 1.. The frame member 16 likewise carries suitable side-boards or retaining walls 18 rising above the upper course of the belt conveyer 12 and confining the zone withinwhich the plastic material 10 is fed to the lower paper sheet 8iand between the said sheet and the sheet 6, so as to prevent escape of the plastic material from such sheets, and to retain it effectively for disposition between such sheets.

C designates a cutter shown in working position in F ig, 1- andin detached-position in Fig. 2, such cutter being used for successively severing the plaster-board ,units A from the stock-consisting of the advancing upper 'andlower sheets 6 and"8 and the interposed plasticmaterial. .Sucn cutter is utilized during the movementof such stock which is designated D, and is applied to the conveyer 12 and the upper course thereof during the movement thereof, being passed between such upper course of the ponYeyer and the stock D, the severing action taking place while the.stock. and conveyerrare'moving in the direction of the arrow in F ig.'" 1.:

In order to obtain .units A which, with the standard width predetermined in accordance with the width of the sheets 6 and 8, which have predetermined lengths, asuitable measuring stick or rule 0 is utilized, the same being placed upon the advancing stock D with one end even with the advancing end of the stock. This rule'being of the proper length required for each unit,'or' for the next unit A, the cutter C- is slipped'between the upper course of the conveyer and the stock D at the other end of the ruler or measuring stick, and is operated to sever the unit beneath themeasuring stick from the stock during the movement of the stock upon the conveyer. Thus, there is no halt in the procedure of forming and feeding the stock incident to subdividing it, the severed unit beinglifted by the operator or operators and placed upon the stack upon the table B, the ruler having first been lifted and thrown back onto the advancing end of the stock'next adjacent to the severed unit, for the purpose of measuring off the next succeeding unit to be severed. 7

The cutter C comprises an elongated frame or body 19 provided atone ehd with a hand-grasp or handle 20, and at the other end with a nose or point 21 slightly back of the terminal portion of which, as at 22, is attached one end ofa cutting wire,'cord or the like 23, of substantially the same length as the body 19, and the other or free end of which is provided with a handle or hand-grasp 24 adapted to lie flat upon the handle 20, with the cutting wire or cord 23 substantially flat-upon the body portion 19, with the parts in the last mentioned positions or relations," the handles 20 and 24 may be grasped in one or both hands and the'nose 21 passed beneath the stock D and above the upper course of the conveyer 12 at the followingor rearward end of the 'roller or gage stick 0, the nose 21 readily mak ng a passage for itself beneath the stock and traversing the smooth belt conveyer. l/Vhen such traverse has been completed, so that the cutter lies entirely transverse of and beneath the stock, the handle 20 is grasped by'the operator in one hand, and the handle 24 in the other hand, such latter handle being raised and the cutter wire 23 meanwhile put under strain or pulled upon, whereupon, as clearly indicated in Fig. 1, the cutter wire is caused to out and sever the stock D transversely at the jfollowing end of. the gage sticlrc to sever a unit-A beneath suc'hggage stick from age, remainder of the stock. This; operati'on is performed While the stoclcis.inovingupbn the conveyer, .tlie ooerator movlng. aloil'g beside the conveyer and ad ancing stock. When the severance is completed the-measuring gage 0 is, as stated, pliaced backiupon. the advancing freshhend of thstbk, the severed unit is deposited upon thertable B, and the operator then proceeds to sever the next succeeding unit A from the stock in the same mannergand so on indefinitely.

The use of the cutter disclosed, in the manner set forth, namely, during the advance of the stock, obviates any necessity of halting suchadvaiice to produce the severance ofeach unl as would otherwise be necessary to produce a clean unmutilating cut,.in the use of a cutter'having'a fixed position of service. Furthermore, the cutter operating inan upward direction, the belt conveyer is saved fromany mutilation or injury which would be.-likely to occur upon the down stroke of any cutter acting upon the stock, and particularly were any cutter. element employed other than the wire or cord or the like 23, which latter, in accordance with the invention, is at all times isolated from the conveyer by the relatively broad cutter body 19. The use of such a cutter permits of speedy and continuous operation of the machine or apparatus, together with accurate severance of the units from the advanced stock, and the subsequent disposition of such units as may be desired. i

In accordance with the invention of the patent and application hereinabove' referred to, the severance of the units and the stacking of the same rapidly in succession is a particular advantage, the paper of the sheets corresponding to the sheets 6 and 8 being so composed as to retard permeation of the same by moisture, thus permitting the sheets to be drawn or slid one over the other into stacked relation, after severance from the stock. \Vere the paper not so organized, the units would become superficially moist and stick together and prevent such sliding action, so that such a cutter is particularly advantageous in use in accordance with the invention of said application and patent. But we do not wish to be understood as in any sense acquiescing in a limiting or confining of the present invention to applicability to the inventions of said other application and of said patent, the invention being likewise susceptible to many changes in provision, construction, formation, combination, association and relative arrangement of parts, members and features, in adapting the present invention to varying conditions of use and service, and within a fair interpretation of the invention.
