SHELDON WARD VANCE, OF CROOKSTON, MINNESOTA.

BRICK-TRUCK.

SPECIFICATION forming part of Letters Patent No. 716,599, dated December 23, 1902.

Application filed May 17, 1902. Serial No. 107,731. (No model) To all whom, it puny concern.-

Be it known that LSHELDoN WARD VANoE, a citizen of the United States, residing at Crookston, in the county of Polk and State of Minnesota, have invented certain new and useful Improvements in Brick- Trucks, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to hand-trucks primarily intended for carrying brick, and is particularly designed to facilitate the transfer of bricks from one conveying-vehicle to another-as, for instance, from a wagon to a car, or vice versaand for transferring brick from a vehicle to the ground, although its use is not limited to this single purpose; but it may be employed in many situations-such as setting brick in oblong downdraft-kilns, &c.which will readily suggest themselves when the invention is understood.

The object of the invention is to provide means for transporting corded or regularlypiled brick from one receptacle to another or from place to place without disturbing the formation of the pile, and thus save the time and labor which are usually expended in arranging and piling bricks which are dumped in a heap, as is the usual custom.

To this end the invention includes a truck having a body portion with which a liftingframe, shiftable in relation thereto, is associated to permit of a load being raised from its rest and supported entirely upon the truck before the latter is tilted to balance the load for transportation.

It further includes the provision of a plurality of lifting or supporting frames to engage the load at different points.

It further includes means for giving said frames relative movement.

It also includes adjustable engaging devices combined with one of said frames; and it further includes the details of construction, as will be hereinafter described, and particularly pointed out in the claims.

\Vhile the presentinvention is susceptible of many embodiments in which the details of construction and combination of parts may be varied within wide range without departing from the spirit of the invention, I have illustrated in the accompanying drawings and will hereinafter describe what I now conceive to be the preferred embodiment of the same.

In the drawings, Figure 1 is a perspective view of the improved truck with a load supported thereon, the same being tilted rear- Wardly. Fig. 2 is a side elevation of the truck resting upon the fingers of the fixed frame with the movable frame in raised position. Fig. 3 is a plan view of the fixed frame, showing the wings in extended positions. Fig. 4 is a detailed view of one of the side bars with some of the parts associated with the same. Fig. 5 is a front elevation of the truck with the same resting upon the fingers of the fixed frame. Fig. 6 is a cross-sectional view of a wagon-body with the brick piled or corded therein.

As before premised, the truck illustrated in the drawings is particularly adapted for transferring brick to and from a wagon the body of which is constructed as shown in Fig. 6, in which a bottom (1 thereof is provided with a plurality of narrow parallel strips 1), running longitudinally of the same. In this .wagon the bricks are corded or piled in a plurality of rows of superimposed tiers, the bottom brick l of each row being supported upon the strips 5, with its side edges slightly overhanging the same. As shown, the strips are somewhat narrower than the width of a. brick and are spaced about the length of a brick apart, measuring from center to center of the same. The bottom brick of each row is laid upon its strip parallel therewith, and the next tier, comprising three bricks 2 of the rows, are then laid transversely thereupon upon their edges, so that the end of said bricks 2 of the adjacent rows abut against one another. The truck to be described is intended to lift and carry at each load a cord or block of bricks comprising all the rows extending transversely ofthe wagon and two rows deep or longitudinally of the same and to lift and support said load intact, (the load being raised off its support before the truck is tilted to balance the same.) The bottom brick of each row and the bricks 2 forming the first tier are engaged by the lifting members of the truck, and for this purpose two lifting-frames are provided. Both of-said frames are secured to the main truck-frame 0, comprising the side bars a,

having their rear ends turned to provide handles and suitable parallel and transverse bracing-bars c". To the side bars 0, near the front ends thereof, bearing-brackets are bolted in which the axle c of the supportingwheel 0 is journaled.

Extending at right angles from the front end of the truck-frame is the stationary lifting-frame, comprising a plurality of'equidistaut-spaced fingers which are provided with a plurality of shiftable wings which provide engaging and supporting members. In the embodiment of the invention illustrated in the accompanyin g d rawin gs each finger 01 comprises a pair of tubular members, preferably constructed of ordinary gas-pipe, having angular rear portions secured rigidly to the back of the truck-frame c in any desired manner, and between the forwardly -extending members d suitable plates or strips e are secured, upon which the wings before referred to are pivotally supported. Each forwardlyextending finger is preferably of the length of two bricks, and with each finger two wings are associated, which are so spaced that when the fingers are pushed beneath a load of brick, piled, as before described, said wings will come approximately centrally of the lengths of the bottom bricks 1. Each wing, with the exception of those associated with the end fingers, comprises a flat oblong plate of substantially the width of the member to which it is pivoted and of greater length than said width, so that when the wings are turned transversely of the fingers they will project beyond thelside edges thereof.

The wings associated with the end fingers are only one -half the length of the other type of Wings, as they are only intended to project over the inner edges of the members carrying the same. To rotate the wings on their pivots, so that they may be thrown either into parallelism with or transversely of the fingers d, an operating-rod g is associated with each pair of the same. The rods 9 extend parallel with the fingers and are pivotally connected to the wings eccentrically of the same. The ends of said rods are connected to a common cross-bar t', slidably secured in the ends of levers 7o, pivoted to the side bar 0 and connected at their upper ends by a cross-bar Z, which forms a hand-lever for operating the parts. As will be apparent by pulling back or pushing forward on the bar I the levers 7c will be rocked and through bar 1' and rods g the wings shifted to project their edges beyond the edges of the fingers d or to retract the same.

With the truck-frame a movable lifting and supporting frameis also associated, which includes a plurality of equidistant-spaced fingers m, arranged directly above and in parallelism with the fingers d. Each finger m comprises two parallel tubular members having a forwardly-extending free portion and a right-angular extending part m, which slides in guiding-brackets n, secured to the crossbars of the truck-frame c. The fingers m are rigidly connected to one another at the ends of the sliding parts m by a flat cross-bar 0, bolted to the same and provided adjacent to each side bar 0' with a notch o, in which a hook 19, secured to a cam lifting-lever r, engages. Each of said levers r is pivoted to the inside face of each side bar a and is.provided with a bearing edge that coacts with a bearing-bar r' to relieve the pivot of the lever from strain when the movable frame is lifted, as will be hereinafter described. When the free ends of the levers are thrown in the direction indicated by the \arrow, they will through the hooks p coacting with the plates 0 raise the movable frame in relation to the truck-frame c. To look the levers r in adjusted positions and therethrough maintain the movable frame in raised position, struts s are provided which are pivoted at one of their ends to the side bar a, While their opposite ends engage with notches in the rear edge of the levers r.

A wheelbarrow-truck of the type disclosed must be provided with legs at its rear to support the handles of the side bars clear of the ground, and to provide said legs I have utilized the levers I. For this purpose each lever is made of two sections pivotally connected at their adjacent ends in such a manner that when the handle of the lever is moved in one direction the sections will be rigidly locked together and moved as one piece, but when the free end is thrown in the opposite direction it will move independently of the section to which it is connected. This effect may be accomplished in many ways, but in the present drawings I have shown the sections of each lever provided with corresponding beveled abutting ends which engage above the pivotal point of the sections. To raise the movable frame to its highest position, the lovers 7' are moved to a position at right angles to the side bar 0 and locked in place by the struts 8. If the free ends of the levers are then pushed toward the handle ends of the side bar 0, the outer or lower sections will partake of independent movements, and as the upper sections are locked rigidly by the struts 8 they will act as legs for the truck-body.

The truck is used in the following manner, assuming that the bricks to be transferred to a car have been piled in a wagon, as indicated in Fig. 6: The movable frame is dropped into its lowest position, when the fingers m thereof will rest directly upon the fingers d. The truck is then tilted forward to rest upon the latter fingers D, and in this position (shown in Fig. 2) it is shoved beneath the load, the fingers d m entering the spaces between the strips 17 and between the sides of the wagon and the adjacent strips, and if the wings are in retracted positions the cross- IIO bar Z is drawn back, which-through the inthereof beyond the edges of the fingers (1, so that the edges of said Wings will project beneath the bottom edges ofthe bricks 1. The levers 1', which are connected to move in unison, are then depressed,and through the links or hooks 1) and bar 0 the movable frame is raised until the fingers m thereof engage with the edges of the bricks 2', and in the continued raising of said movable frame the part of the load above the bottom bricks is slightly raised therefrom. The truck is then tilted rearwardly and is balanced upon the wheel c To facilitate the latter operation,

.the angles 1 of the fingers (Z are rounded.

The load being thus lifted, it is transferred into the car, and the reverse operation of the truck takes place-that is, the truck is first tilted forward to rest upon the fingers (l, the bar Z pushed forward to tilt the levers 7; and through the rods g rotate the' wings, and thus withdraw the same from beneath the edges of the bottom bricks 1, when the latter will drop upon the floor of the car. The levers r are then released,and the movable frame through the weight of the load will drop and lower the loadinto its former position upon or in relation to the bottom bricks 1. As there are no strips similar to stripsborcorrespondingelementsin the car, a slightly-different action or manipulation must be employed to transfer a load intact, or substantially so, from a car to a wagon, or in fact from any place not provided with supports for the bottom bricks corresponding to the strips 1). In the latter case the movable frame having been lowered and the truck tilted to rest upon the fingers d said fingers, with the wings retracted and the fingers on resting upon the same. are pushed beneath the overhanging edges of the bricks 2. The levers r are then depressed as before to raise the movable frame and therewith the bricks piled upon the bottom bricks from the latter. The truck is then rocked back to rest upon the wheels c aud the barl manipulated to throw out the wings. The attendant then picks up the bottom bricks and inserts the same between said wings and the second tier of bricks, so that when dumped the pile will be intact. In inserting the bricks 1 they are merely slid in place from the forward end of the frame, each pair of fingers m providing a channel the bottom of which is formed by a finger (Z to receive said bricks. The fingers 'm thus provide means to prevent thelateraldisplacementof saidbottom bricks.

From the foregoing it will be appreciated that I have provided an exceedingly simple and easily-operated truck which will transfer intact from place to place loads of regularlypiled brick withoutnecessitating the bandling of the individual bricks, except in the case of the bottom bricks, where no supporting-strips are provided therefor.

It will be understood that a suitable platform or inclined way is associated witha car or wagon upon which the truck may be run in transferring brick from the ground thereto, or vice versa.
