LUMBER-STACKING TRUCK.

SPECIFICATION forming part of Letters Patent No. 619,237, dated February '7, 1899.

Application filed July 19, 1897. Renewed July 15, 1898- Serial No. 686,038. (No model.)

To all whom it may concern:

Be it known that 1, GEORGE W. SoULn, a citizen of the United States, residing at Meridian, in the county of Lauderdale and State of Mississippi, have invented certain new and useful Improvements in Lumber Stacking 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.

My invention relates to improvements in lumber-stacking trucks for sawmill plants; and it has for its object, among other things, to accomplish the ready and effective binding of the stacked lumber on the truck; also, to lessen the cost of manufacture of the standard sockets or pockets and to povide for the automatic locking of the binding device or applianee.

To these ends the invention consists in the peculiarity of construction of the standard sockets or pockets; also, of the binding or straining appliances and of the means for locking the said appliances, substantially as hereinafter more fully disclosed, and specifically pointed out in the claims.

In the accompanying drawings, Figure 1 illustrates a partly-broken-away perspective view of my invention. Fig. 2 is an enlarged detail view of one of the standard sockets or pockets. Fig. 3 is a like view of the locking device, and Fig. 4 is a detached view of the locking head or clamp of the binding appliance or device.

In carrying out my invention I construct the body of the truck A preferably of two spaced pieces, either of wood or metal, and provided with suitable traction-wheels. At each end of the truck I provide a socket or pocket B, which is formed by securing an open, preferably rectangular, bottom casting b and a similar-shaped top casting b to the bottom and top sides, respectively, of the truck at each end thereof, the top and bottom castings forming, with the inner walls of the timbers or metal bars constituting the body of the truck, a continuous socket or pocket extending through the depth of the truckbody, by which it will be observed that a strong, light, and cheap pocket of required depth is secured without the attending expense of an integral iron socket of ordinary construction.

If desired, the truck may be constructed of a single piece of wood or metal and recessed at its ends or formed with an opening near each end and the bottom and top castings b and b secured in position around the recess or opening on the top and bottom sides of the truck, as just described. Within these pockets or sockets are placed the usual standards 0, between which the lumber is stacked in the usual way, as will be readily seen.

D is a binding rope or cable, to one end of which is attached a loop (1, which readily fits over the upper end of one of said standards without requiring any previous special adaptation therefor, the "rope or cable then being passed across the stack of lumber and over the top of the opposite standard, into which it readily embeds itself when under strain, and thence down about midway of said latter standard, where it is carried to one side of the standard and seen red to a'binder-head E,which latter is adapted to grip the standard upon three sides. This binder-headE is preferably provided with a tapering tooth or projection e, which impinges upon the standard C when strain is brought upon the cable or rope. After the lumber has been on the truck sufficiently long to dry the binding rope or cable will slacken somewhat, but the tooth or projection e on the binder-head being firmly embedded in the standard prevents the said head from swinging accidentally away from g the standard.

F refers to the pull-down or locking device, which consists of a clamp f, with one end having preferably an inclined inner face f adapted to bite or impinge one side of the standard, and a handle or lever f, pivoted at its inner end, preferably, in ears on the opposite end of said clamp and provided with a preferably bifurcated cant-like hook f pivoted to said lever near its fulcrum, which is designed and adapted to engage,preferably, a recess or depression 6 on one end of the binder-head E, to which the rope or cable is secured, the bifurcation of the hook permitting the ready passage of the rope or cable therethrough. It will be seen that the binderhead is automatic in its locking action, since as the binding rope or cable pulls upward upon one end of the binder-head the latter will automatically bind or impinge upon the standard. By applying the pull-down device to said binder-head the hook or hooks f enby'the binding-wire, thus causing it (the said binder-head) to take a fresh grip upon the standard,which operation can be repeated until the required strain is put on said bindingwire to efiectively hold the lumber stacked.

As previously stated, it will be seen that by means ofmy invention binding apparatus is provided which is exceedingly simple and effective in its action and can be operated with great facility and expedition, as well as bemore cheaply manufactured.

Having now described my invention, what I claim as new, and'desire to secure by Letters Patent, is

1. A lumber-stacking truck composed of a body portion or frame having a recess or opening and provided with traction-wheels, and an upper and alower casting, preferably rectangular in shape secured to the upper and under side of the truck-frame in line with the recess or opening and forming with the walls of the recess or opening a continuous socket for a standard, substantially as described.

2. In a. lumber-stacking truck, a binding wire or cable having a loop at one end adapted Lo engage the upper end of one standard of the truck and passed over the upper end of the-opposite standard of said truck and having its free end attached to a binder-head adapted to bind or impinge upon said standard,'substantially as described.

3. In alumber-stackin g truck,the combination with a-looped wire and its binder-head, of a pull-down or lockin g device consisting of a clamp adapted to engage a standard of the truck, a handle or lever pivoted to said clamp, and a cant-like hook adapted to engage said binder-head, substantially as described.

4. A locking device for use on a lumberstacking truck consisting of a clamp having a gripping-jaw, a handle or lever pivoted to saidclamp and a cant-like hook pivoted on said lever, substantially as described.

5. A locking device for use on a lumberstacking truck, consisting of a clamp having an inclined inner portion, a handle or lever pivoted to said clamp, and a cant-like hook pivoted on said lever, substantially as described.

6. A locking device for use on a lumberstackingtruck, consisting of a clamp having an inner inclined portion, a handle or lever pivoted to said clamp and a bifurcated cantli ke hook substantially as described.

7. A lumber-stacking truck having a body or frame portion formed of spaced timbers or metal bars provided with traction-Wheels, and an upper and a lower open casting rectangular-in shape secured to theupper and under sideof the truck-frame, and forming with the inner walls of the truck-frame a continuous socket for a standard, substantially as described.

8. In a lumber-stacking truck, a binding wire or cable adapted to engage the upper end of one standard of the truck, and passed over theupper end of the opposite standard of said truck, and having its free end attached to a binder-head, said binder-head consisting of a casting provided with an approximately rectangular opening which is adapted to engage the standard on three sides, substantially as described.

9. A lumber-stacking truck composed of a body portion or frame having a recess or opening and provided with traction-wheels and an upper and a lower casting provided with an opening preferably rectangular in shape, secured to the upper and under side of the truckframe in line with the recess or opening, and forming with the walls of the recess or opening a continuous socket fora standard, abinding wire or cable adapted to engage the upper end of one of the standards of the truck and passed over the upper end of the opposite standard of the said truck, and having its free end attached to a binder-head adapted to bind or impinge upon the sides of the standard, substantially as described.

10. A lumber-stacking truck composed of a body portion or frame having a recess or 5 opening and provided with traction-wheels and an upper and a lower casting preferably rectangular in shape, secured to the upper and under side of the truck-frame in line with 1 the recess or opening, and forming with the walls of the recess or opening a continuous socket for a standard, a binding wire or cable "adapted to engage the upper end of one of the standards of the truck and passed over the upper end of the opposite standard of the i said truck, and having its free end attached 1 to a binder-head adapted to bind or impinge 1 upon the sides of the standard, a locking device consisting of a clamp having a grippingjaw, a handle or lever pivoted to said clamp, and a cant-like hook pivoted to said lever, substantially as described.

11. In a lumber-stacking truck, a binding wire or cable having a loop at one end adapted to engage a standard of the truck and passed over the upper end of an opposite standard, a binder-head attached to said cable and consisting of a casting formed with an approximately rectangular-shaped open ing, and a penetrating projection in one of the walls of the opening adapted to penetrate a truck-standard and prevent the'binder-head 'from swinging accidentally away from the standard after the lumber is dry,substantially as described.

In testimony whereof I hereunto affix my signature in presence of two witnesses.
