BRICK-TRUCK.

SPECIFICATION formingpart of Letters Patent No. 673,232, dated April 30, 1901.

Application filed December 20. 1900- Serial No. 40,506. (No model) To all whom it may concern.-

Be it known that I, BYRON E. BEOHTEL, a subject of the Queen of Great Britain, residing at Waterloo, Province of Ontario, Dominion of Canada, have invented certain new anduseful Improvements in Brick-Trucks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to certain improvements in brick-trucks, and particularly to an improved construction of truck adapted to carry the green bricks from the brick-machine into the hacks or drying-tunnel, and from thence after the green bricks have been dried to the brick-kiln; and the objects and nature of my invention will be obvious to those skilled in the art in view of the following detailed explanations of the accompanying drawings.

My invention consists in certain novel features in construction and in combinations and in arrangements of parts, as more fully and particularly pointed out and described hereinafter.

Referring to the accompanying drawings, Figure 1 is a perspective view of the truck without its load of bricks, showing the same in about the position it assumes immediately after picking up a loaded pallet or just before depositing it on the supports. Fig. 2is a side elevation of the truck and a pallet of bricks thereon, the truck being shown in the position it assumes while transporting a load. Fig. 3 is a cross-section through a hack or drying-tunnel, showing the truck therein in rear elevation and in the position shown in Fig. 2. Fig. 4 is a detail perspective View of one of the brackets. Fig. 5 is a detail perspective view of a pivoted footpiece detached from its bracket.

In the drawings, a is a drying-tunnel, the floor of which is provided with the track extending longitu dinally therethrough and preferably extending from the brick'machine through said tunnel to the brick-kiln. This track is composed of the separated suitably constructed and arranged flat (or otherwise formed) rails b b.

c c are supporting rails or beams arranged longitudinally along the floor of the dryingtunnel, preferably parallel with the trackrails, and usually, although not necessarily, arranged between the track-rails. These supporting-beams are preferably of greater height than the track-rails, with their upper edges in a horizontal plane above the plane of the track-rails.

Usually wheeling-in and off-bearing bricktrucks are employed in a plant such as hereinbefore referred to. The ofi-bearing truck is employed to convey the green bricks from the brick-machine and deposit the same in the drying-chamber, while the wheeling-in truck is employed to convey the dried bricks from the drying-tunnel to the brick-kiln. These two trucks are usually, broadly considered, the same in construction, although I have illustrated a truck particularly intended and adapted for use as a wheeling-in truck.

Referring to my truck as illustrated in the drawings, d is the platform or bed thereof, preferably comprising two parallel side beams suitably and rigidly secured together by crosspieces. This platform is suitably formed to receive the pile or stack ofbricks on the loaded pallet upheld on the platform by a suitable bottom ledge or support. This bottom ledge or support can be formed about as shown by one or more forwardly-projecting strong rigid toes, brackets, or fingers e e. In the present instance I show two such brackets e e secured rigidly to the lower ends of said side beams, respectively, and projecting forwardly a suitable distance approximately at right angles to the length or plane of the platform. The inner ends of these brackets are usually, although not necessarily, secured to the inner side faces of the lower ends of the said side beams, and from thence deflected forwardly and properly spaced to pass beside the supporting rails or beams in depositing the loaded pallet thereon or in removing the same therefrom. If desired, the bottom ledge can be provided with a tilting support or foot having a limited vertically-tilting movement. As an example of a device which might be employed for this purpose I show each bracket 6 provided with a tilting foot or support e,

consisting of an elongated bar arranged longitudinally along and normally resting on the top edge of the bracket and projecting outwardly a suitable distance beyond the end of the bracket, as more clearly shown in Fig. 4:- g This foot is suitably hinged or pivoted to the bracket to swing on a horizontal axis at a point intermediate thelength of the foot. In the example shown the foot is provided with ears depending on opposite sides of the bracket and joined thereto by a horizontal pivot 6 'These ears are located a distance in rear of the front or outer end of the footpiece and preferably at'or near the front end of the bracket. The footpiece is provided with means to limit its swing upward'from the top edge of the bracket. For this purpose I show a rigid stop projection or arm 6 depending from the rear end of the foot, with its end turned laterally and projecting under the bracket to engage the under edge thereof when the foot reaches its limit of swing away from the bracket. The hinged footpieces are in length preferably equal to the width of the pallet or board on which the bricks are piled. Said footpieces are adapted to engage the under surface of the pallet and rest thereagainst parallel with the plane of the pallet and form a firm base and support therefor, although the plane of the pallet may not be parallel with the top edges of the brackets nor be exactly at right angles to the plane of the supporting platform against which the bricks rest. In loading the truck these pivoted feet will permit the bricks to tilt easily against the supportingplatform and will afford a firm footing for the loaded pallet, although the bricks may not be so stacked or piled thereon as to rest evenly against the platform. In practice I have found that material advantages are attained by the employment of this tilting base or support, although I do not wish to limit other features of myinvention to employment therewith.

ff are two rigid handle-bars, at their lower forward ends rigidly secured to the said side beams of the platform at points intermediate the lengths ofsaid side beams. Usually said handle-bars are secured to said side beams at points a short distance above the lower end of said platform. The handle-bars extend rearwardly from the upwardly extending platform at an acute angle to the plane of the platform-say, at an angle of about forty-five degrees, although my invention is not so limited, as hereinafter pointed out. The outer portions ofthe handle-bars are provided with the depending legs gg, rigidly secured thereto and suitably braced. These legs preferably extend down from the handle-bars at right angles thereto.

h h are rigid braces from a cross-bar connecting the handle-bars to a rigid cross-bar connecting the upper portions of said side beams of the platform.

71 is a cross-axle secured to the handle-bars usuallya suitable distance in rear of their lower or front ends.

i z" are the truck or supporting wheels, mounted on the axle and adapted to travel on said track-rails hereinbefore referred to.

The construction of the truck is such that the axle of the supporting-wheels is located a distance in rear of andin a horizontal plane above the lower supporting-brackets of the platform, whereby certain material advantages are attained in a truck of the character described. I

' j is a pad or cushion secured on the front face of the platform and constituting the green-brick-engaging face or surface thereof. This pad is preferably composed of a heavy layer of felt or equivalent material, which is of sufficient thickness to'form a cushion for the dry bricks and prevent chipping thereof or injury by contact with hard surfaces by reasonof the jars andvibration incident to transportation on said truck. Usually I do not provide the off b'earing' truck with such a cushion, but I consider it an important improvement for the wheeling-in truck, which carries the dried bricks from the'drying-tunnel; but I do not wish to limit other features of my invention thereto.

Often the wheeling-inand off-bearing trucks also differ in respect to the distance'between their bottom-su pporting brackets. However, I do not wish to limit my inventionto either wheeling-in or off-bearing trucks, as my inventionlcomprises bothf'ortns of truck.

The truck is so constructed and arranged that it can be advanced to a pallet loaded with bricks and resting on the supportingbeams and by elevating the handlerbars slightly the platform will assume a vertical position and the lower" support (brackets) thereof a horizontal position, and said supports will pass beside said supporting-beams and beneath the" pallet carrying the bricks. Then on slightly'depressing the handle-bars the pallet will be elevated on and by said brackets and the bricks will rest on" the platform against the cushioned surface thereof. The truck will easily elevate the load of bricks because of the location of the axle (fulcrum of the lever) in rear of and considerably above the loadthat is, the brackets which carry the bricks. Also during transportation the load is practically balanced on 'theaxle and can be easily handled in loading, transporting, and depositing by a single operator, as a large portion of the weight is below the plane of the" axle, and hence not between the axle and handle portions of the handlebars: During transportation the weight is largely in front of the axle and the load of bricks rests easily on the platform, which is then inclined at such an angle rearwardly from the vertical or perpendicular position that the bricks rest against the platform and greatly relieve the weight on the lower bricks and pallet. The loaded pallet can be easily deposited by elevating the handle until the brackets assume a horizontal position and the pallet rests on the supporting-beams and then withdrawing the truck.

The arrangement of parts in my truck is such that when the truck is tilted forwardly and the brackets are in a horizontal position to receive the load and the truck is then tilted back to elevate the load the brackets and the platform will move forwardlythat is, in a direction toward theload-and upwardly and in an arc and not upwardly and backwardly in an arc in a direction away from the load. Certain material advantages are attained in that the pallet and bricks thereon when lifted by the truck will be located completely up against the platform. Also notwithstanding the fact that during transportation the bricks extend below the plane of the axle of my truck and in advance thereof, yet when the loaded truck is lowered, with the legs resting on the ground, the weight of the load will be properly distributed between the legs and wheels, and the truck will have no tendency to tilt forward.

In my truck the angle of the carrying-frame or platform in respect to the handle-bars is in proportion to the height of the supportingwheels and the amount of leverage necessary.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent of the United States, is
