PORTABLE BRlCK-HACK.

SPECIFICATION forming part of Letters Patent No. 326,812, dated September 22, 1885.

Application filed June 16, 1885.

To all whom it may concern.-

Be it known that we, Maroon XVALKER and EPHRAIM MINER, citizens of the United States, residing at Yankton, in the county of Yankton and Territory of Dakota, have invented certain new and useful Improvements in Portable Brick-Hacks, of which the following is aspecifieation, reference being had therein to the accompanying drawings.

Figure 1 is a perspective view of this device as in use. Fig. 2 is a perspective view of the frame and carriage ready for taking up the hack.

The object of our invention is to provide a means whereby a large number of bricks may be easily carried from place to placein a brickyard or other place with no more help than is ordinarily employed to carry a much smaller quantity.

Another object of our invention is to provide a device for carrying bricks which shall be so etlicient as to render the accidental dropping of a brick-hack full of bricks practically impossible.

In the usual way of carrying bricks from the yard to the kiln, or vice versa, there is much danger of accidental stumbling, and conse quent dropping of bricks, which, besides being the source of much annoyance, is very disadvantageous, as much time is thus lost, and the loss caused by the breaking of bricks is also considerable. Again, by carrying the bricks in the hands in the old way, all of the strain comes directly on the arms of the carrier, and he can only carry a comparatively small number of bricks, whereas by the cur ployment of our device the same person can carry many times the number which he could carry in his arms or on a hack in his hands, and with absolute safety as regards accidental dropping-first, because the hack, when be ing carried by our device, is so close to the ground that the fall would cause no material concussion, and, second, because the person using the machine, even if he were to fall, would not drop the bricks, as the machine will support the bricks independent of the operator.

This device is designed especially for handling or moving green bricks. By any other device for that purpose that we know of,

(No model.)

the green bricks, (that is, the freshly molded,) when taken from the machine, are placed into a flat wheelbarrow and carried to the yard, where they are taken from the wheelbarrow and hacked up. \Vhen they are dried they are again loaded on the wheelbarrow to be taken to the kiln. By the present invention they are placed directly from the machine upon the hack and wheeled to the yard, set down, dried, and then taken by the carriage to the kiln. Thereby a large part of the labor in loading and unloading the hack is avoided, and in a large brick-yard at least fifty per cent. of this kind of labor is saved.

Having set forth the main object of our invention, we will now proceed to describe it in detail.

It consists in a novel construction, arrangement, and combination of parts, which will be hereinafter explained, and more especially.

pointed out in the claims.

In the accompanying drawings, A designates the frame, secured together by any suitable number ofcross-bars, the front one, a, of which is used as a handle in raising or lowering the frame or moving the carriage. The rear bar, a, has on its outer sides the hooks b, the purpose of which will be described hereinafter. At the rear end of the frame A are two eccentric crank-arms, O C-one on each sidethe lower outer ends of which form the axles for the wheels D l).

Extending diagonally downward and backward from the side bars of frame A are the braces E Eone on each sideand from the rear of the same bars are a pair of secondary braces, E E-one 011 each side-extending diagonally downward and forward, and crossing the arms E E at c. This portion of the device we call the cart or carriage. The skeleton frame F, preferably made of strong wire, is hung by its horizontal bar or piece], or in any suitable way, upon the hooks b on the rear bar of the frame A. Each of the flaring wires or bars ff on each side has hooked ends f".- These ends are adapted to engage under the projections g on each side of the hack G.

It will be observed that when the device is in the position shown in dotted lines in Fig. 2, the front end of the frame A being raised,

ICO

the rear of the frame will be lowered and the frame F will come nearer the ground, and so ready for its ends to beengaged on the sideprojections of the brick-hack.

The operation of this device is as follows: The hack being properly filled or loaded with brick, the carriage is wheeled up to the end of v the hack and is moved along over it, the wheels being astride the hack. Then by lifting up the forward part of the frame the ends f 3 of the frame F are lowered and can be engaged under the side projections of the hack. Now, by pressing down on the front bar or handle of frame A, the ends of the longer downwardly-projecting side bars will be the fulcra on which the frame F will be caused to raise the hack till it swings free from the ground and the load of bricks is in a position to be wheeled away. To unload, reverse the above operation. The ends of the shorter side bars are supports for the frame A when the carriage is not used. By having two braces on each side the frame is very much stronger.

It is evident that in the mere detail of construction there may be many merely mechanical changes in the, above construction which will in no manner change the nature or scope of our invention.

We are aware that a hive-truck has been constructed similar to our devicei. e., it was provided with two wheels and a pair of handles. It also had a' system of levers which served to facilitate the raising of a hive from the ground and suspending the main part of the weight from the axle; but our device is designed especially for carrying flat brick-hacks, and it is much less complicated, while it accomplishes the result aimed at without the employment of any levers except the handles, which serve as a means for steadying the truck. We therefore disclaim the hive-truck above referred to; and

What we desire to secure by Letters Patent, and what we really do claim, is

1. In a brick-carrying machine, the combination of the main frame and the eccentric crank-arm with the wheels and suitable supports and supporting-frame for the hack, as set forth. v

2. In a brick-carrying machine, the combination of the main frame, the wheels, and crank-arms with the hooks b b at the front end of the frame, and frame F, having the hooked ends, as set forth.

3. In a brick-carrying machine, the frame, the cross-bars a and a, the hooks b b on the latter forward of the axle-supports or eccentric arms, and the hooked rods F F, with the arms f as set forth.

4. In a brick-carrying machine, the main frame having side braces or supports, E E, the latter serving the double purpose of a brace and a supplemental handle, the crankaxles G, the hooks b b, and the hooked rods F F, all combined in the manner and for the purpose set forth. r

In testimony whereof we affix our signatures in presence of two Witnesses.
