' ELEVATING-TRUCK- Specification of Letters Patent.

Application filed December 5, 1904. Serial No. 235,492.

for hauling brick and similar articles or commodities which are to be placed for drying or burning or stored for any other purpose.

My truck is specially adapted for liftin pallets loaded with brick and carrying sai pallets, with their loads, and depositing them for dryin and burning, and my truck is adapted or taking such pallets from the ground or floorand again depositing them' upon the ground or floor, sothatelevated frames or racks for receiving and supporting the loaded pallets are unnecessary.

The truck may be operated upon the ground or floor or upon rail-tracks ofany suitable form. V

In the accompanying drawings, Figure 1 is a side elevation of a truck embodying my improvement. Fig. 2 is an end elevation of the same truck. Fig. 3 is a plan. Fig. 4 is a horizontal transverse section on the line 4 4 of Fig. 1. Fig. 5 is a horizontal sectional view of mechanism for simultaneously turning the supporting-arms. Fig. 6 is a detail sectional elevation of the mechanism for turning the supporting-arms.

Referring to said drawings, 1 1 1 1 are sup-.

porting-wheels arranged in pairs, and 2 2 are I as by mean O bolts 9.

ordinary cylindric axles extending through pairs. of'said wheels and secured immovably to the latter. Said wheels support-a frame consisting of lower side plates 3, upper side plates 4, and four upright corner-posts 5 and four horizontal end bars 6. The side plates 3 are located outside of the wheels 1 and have attached to or formed integral with themselves bearing-blocks 7, in which are horizontal bearings 8, into which extend the ends of the axles 2. By this means said upper side plate 4 is located directly above one of the side plates 3 andsupported by two of the osts 5, intervening'between saidupper si e plate and the adjacent lower side plate. Said posts and said side plates are secured to each other by any suitable means, The transverse bars upright arm 18 of the 5 securing the handle 20 in 1 For this purpose the drawings show a hook 24, hinged by its'lower end I j acent top rail 4 and adapted to extend over Each I one of the arms of said handle when the latter ihas been depressed sufliciently to raise the g arms 10. In addition to this ment of the said su I I j arms are turned hor zontally by the partial irotation of'the shaft ll'in I Said rotation is accomplished by the follow- I ing-described I mechanism:

6 are secured to said posts by bolts 6". Upon said frame are secured the other devices to be hereinafter described. Chief among these are four horizontal arms 10, which are arranged to be raised and lowered a short distance and to be extended transversely outward from each side ofthe machine and to be swun laterally, so as tobecome parallel to the sides of the truck, for purposes to be hereinafter described. Each of said arms is attached to or integral with an upright shaft 1 1, extending through an upright bearing 12 in the said bearing-block 7. To theupper end of each of said shafts another shaft 14 is attached by a swivel-j oint 13.

Patented March 20, 1906.

Adjacent to the upper end of each of the last-mentioned shafts a rock-shaft 15 ismounted upon the upper side plate 4 in bear ings 16. Each such rock-shaft has at its ends a rigid horizontal arm 17, hinged to the upper end of said shaft 1.4, and at the opposite end of the bearings 16 each of said shafts has a rigid upright arm 18. The upper ends of saidupright arms at the same side of the truck are joined by a horizontal connectingbar 19, hinged by its ends to said arms. To the front end of the upper portion of the truclefrarne a U-shaped handle 20 is hinged in bearings 21,-secured to the upper face of the upper side plates 4. From each front adjacent rock-shafts a link 22 extends to the handle 20 and is hinged to the latter at 23.

From the foregoing description it will be readily understood that by raislng and lowering the free end of said handle said rockshafts will be-rocked and the'outer ends of the horizontal arms 17 will be raised and lowered, whereby said upright shafts 14 and 1 1 and the horizontal arms 10 will be raised and lowered. For ordinary pur oses such movement is to be comparativel Usually it will not exceed two or three inches.

Any suitable means may be employed for its lower position.

to the upper adupright moveporting arms 10 said the bearing 12.

Above the lower y limited.

side lates each of said shafts 11 has a .rigid cran -'arm 25 extending toward the opposite shaft 11 at that end of the truck, and said crank-arms at the same side of the machine are joined by a connecting rod 26, which is extended to each end of the truck, so that it can be reached by the hand of the op erator for pushing or pulling said rod lengthwise. The ends of said bar, preferably only the ends adjacent the handle 20, may be prolonged and provided with handles 26*. Such lengthwise movement results in the partial rotation of the shafts 11 and a corresponding lateral movement of the outer ends of said supporting-arms 10. This construction provides for the horizontal shifting of the two erank-arms at one side of the truck independently of the similar crank-arms at the other side of the truck. Simultaneous movement of the said crank-arms at both sides of the truck may be effected by means of the mechanism illustrated in Fig. 5. In said form a cross-bar 27 located approximately at the middle of the truck,is coupled to the connect ing-bars 26 by a bolt 28, extending loosely through longitudinal slots 29 in said crossbar 27 and being rigidly secured to said connecting-bars. Said bolt 28 is long enough to allow upright movement of said connectingbar 26 and cross-bar 27 with reference to each other. A bar 30 extends lengthwise along the middle of the truck and is suitably secured to said cross-bar, as by a bolt,27 and has its ends suitably guided, as by being extended through apertures 31 in the horizontal end bars of the truck-frame. Braces 32 join the cross-bar 27 and the longitudinal bar 30. Since the bolt 28 is relatively long and extends loosely through the slot 29, the connecting-bars 26 are free to partake of the upright movement of the crank-arms 25 and upright shafts 11. Either or both ends of the longitudinal bar 30 may be bent to form a convenient handle 33. From the foregoing description it will be understood that the longitudinal shifting of said longitudinal bar 30 will cause the forward or rearward movement of said cross-bar 27 and the connecting-bars 26, whereby the four supporting-arms 10 are simultaneously turned in a horizontal plane. The operation of the truck is as follows: Two pallets P, having the two supporting cross-pieces or feet F, are placed parallel to each other and at a proper distance from each other to permit the truck to come between them and are then loaded with brick at the press or elsewhere. Any number of pairs of pallets may be thus arranged to be transorted at any time. When a pair of said palets are to be transported to a place for drying, (either in the open air or in a kiln,) the truck is pushed between the pallets constituting a pair, the supporting-arms 10 having been first lowered and turned approximately parallel to the sides of the truck. The truck is set so that one of said arms at each side of the machine has a clear way to swing beneath the pallet between the two feet F, while the other of said arms has a clear way to swing beneath said pallet between one of said feet and the adjacent end of the pallet. Then by drawing down the U-shaped handle 20 the said supporting-arms are simultaneously lifted until they engage and lift said two pallets from the ground or floor. Thereafter the truck, with its load, is pushed or pulled to the place where said pallets are to be set, and by releasing said U-shaped handle 20 said supporting-arms are made free to descend until said pallets again rest upon the floor or ground and said arms are free from the pallets. Then said arms are again turned horizontally until they clear said pallets, after which the truck is hauled away to take another pair of pallets.

It will be observed that this truck is ad apted for use in a brick-yard which has no truck tracks and no pallet-supporting structures whatever. In other words, the truck is ada ted to handle these pallets upon smooth leve ground or upon a smooth level floor. If tracks are desired to make propulsion of the truck easier, such tracks maybe laid approximately level with the ground or floor and the pallets taken from and again deposited upon the ground or floor, and my improved truck is well adapted to the hauling of heavy loads, for the truck has four wheels and the load is evenly divided upon such four wheels. In this connection attention is directed to the fact that each of the horizontal supportingarms may be placed directly opposite one of the wheels, as shown in the drawings, whereby the pallets may be so placed. as to put equal portions of the load upon the front and the rear wheels.

To aid in propelling the truck when it has a load, I have applied a crank-gearing to one end of the truck. From the adjacent upper end bar 6 of the truck-frame a bracket 34 ex tends outward and upward to the level of the upper face of the adjacent upper side plate 4, and a rotary shaft 35 is secured in bearings 36, seated upon said bracket and said side plate. A sprocket-wheel 37 surrounds and is secured to said shaft, and a similar s )roeketwheel 38 surrounds the adjacent axle 2, and a sprocket chain 39 extends around said sprocket-Wheels. The shaft 35 projects beyond said bracket and is there )rovided with a crank 40, whereby said shalt may be retated and the said sprocket-wheels and said sprocket-chain operated for the rotation of the said axle 2. Beneath the crank 40 the lower side plates 3 of the truck-frame may be extended and receive upon their upper faces a platform 41, upon which the operator may stand while propelling the truck by means of said crank.

It is to be understood that in the several portions'of my truck the mechanism may be. varied without departing from the essenceof truck, and mechanism or simultaneously lifting said arms, substantially as described. 2.
