SPECIFICATION forfning part of Letters Patent No. 794,576, dated July 11, 1905. Application filed November 19, 1904. Serial No. 233,462.

To all whom it may concern.-

Be it known that I, ROBERT JoHUA VVIL- LIAMs, a citizen of the United States, and a resident of Natalbany, in the parish of Tangipahoa and State of Louisiana, have invented a' new and Improved Log-Cart, of which the following is a full, clear, and exact descriptiOn.

My invention relates to that class of devices known as log-carts; and it consists in an improvement in the means for loading and unloading logs.

My invention further consists in the construction and combination of parts, as will more fully appear from the detailed description appended hereto and definitely set forth in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a perspective view of my cart with a load of logs in position to be transported. Fig. 2 is a side View of the cart ready to load, parts being broken away and in section. Fig. 3 is a similar view showing the logs in elevated position. Fig. 4 is a rear view of the cart as shown in Fig. 2, and Fig. 5 is a detail view of the automatic catch for holding the logs elevated.

My device comprises a support 1, mounted upon wheels 2 3. Attached to this support are the ordinary hounds 4 5, which are brought in front, as usual, leaving a space for a tongue to be inserted. Upon the middle of the support 1 is mounted a guideway, consisting of uprights and braces 6 7 and connected at the top by a roller 8. Slidingly mounted in this guideway and between the hounds A 5 is a tongue 9, through which is drilled a hole adapted to receive a pin 10, which is intended to hold the tongue 9 in position when the logs are to be transported. The pin 10 catches behind connecting-plates 11 12, which unite the front ends of the hounds 1 5. Upon the rear ends of the hounds and directly over the support 1 are mounted bearing-blocks 13 14, upon which is rotatably mounted a drum 15. This drum 15 has trunnions 16 17, supported in said bearings 13 1 1 and are located eccentrically to said drum. The drum 15 may be made of wood and covered by protecting-rods 18, of iron, or the entire drum may be made of metal. Rigidly attached to the drum is a lever 19, which has mounted in its other end a sheave 20. Between the sheave 20 and the end of the lever 19, attached to the drum, is mounted a hook 21. This hook is adapted to be engaged by a catch 22, mounted in a support 23, located on the hounds. The catch 22 is pivotally mounted at 24 on the support 23, and one end is formed with a handle 25 for releasing the same. The end having the handle is longer and heavier than the end having the catch, and consequently it will always be held in position to engage the hook 21. The upper part of the catch 22 has a cam-surface adapted to be engaged by the hook 21, thus automatically operating the catch.

A chain 26 is rigidly attached at one end to the plate 11. At its other end it is attached to a plate 27, mounted on the tongue 9. Between its ends the chain is passed over the sheave 20. Fastened to the drum 15 are chains 28, which have pairs of hooks 29 attached to their lower ends.

In operation the device acts as follows: The tongue, which is in the position shown in Fig. 2, is made slidable by removing the pin 10, and the sets of hooks 29 are attached to the logs to be transported. The horses or other moving power are attached to the end of the tongue 9, and by this means the chain 26 will draw the lever 19 forward until the book 21 engages the catch 22. The logs are thus raised by reason of the chains being wound on the drum 15. After this operation the tongue is slid back into the position shown in Fig. 2, and the pin is again placed in its opening and the device is ready for the logs to be transported. When ready to unload the logs, all that is necessary is to lift the handle of the catch 22, thus disengaging the hook 21, and the weight of the logs will cause them to drop upon the ground or skids, as required. The hooks will disengage themselves, and the cart is rea for another load.

While I have described one specific form of my invention, I do not wish to be limited to the precise details therein set forth, but only in so far as stated in the claims.

Having thus described my invention, Iclaim as new and desire to secure by Letters Patent 1. In a log-cart, the combination of a support, a drum mounted to rotate on said support, a tongue slidably mounted in said support, a lever connected to said drum, a pulley on the said lever, and aflexible connection between the support and tongue and passing over the pulley, substantially as described.

2. In a log-cart, the combination of a support, hounds connected with the support, a drum mounted to rotate on said support, a tongue slidably mounted in said support and extending between the hounds, a connectingplate uniting the front ends of the hounds, a plate mounted on the tongue in front of the connecting-plate, a lever connected to said drum, a flexible connection between the said connecting-plate and the plate on the tongue,

"the said flexible connection engaging the lever, and apin adapted to extend through a hole in the tongue at the rear of the connecting-plate, substantially as described.

3. In a log-cart, the combination of a support, a drum mounted to rotate on said support, a tongue slidably mounted in said support, a lever connected to said drum, means connected to said lever and tongue for rotating the drum, a hook mounted on the lever, and a catch pivotally mounted on the support and adapted to engage the said hook, the said catch having a handle end heavier than the catch end, substantially as described.

4. In a log-cart, the combination of a support mounted upon wheels, a drum rotatably 'mounted on said support, a lever rigid with said drum, a pulley on the end of said lever, a tongue slidably mounted upon said support, a flexible connection between the support and tongue and passing over the pulley, and means for raising the logs, attached to said drum, substantially as described.

5. In a log-cart, the combination of a support mounted upon wheels, a drum rotatably mounted on said support, a lever rigid with said drum, a pulley on the endof said lever, a tongue slidably mounted upon said support, a flexible connection between the support and tongue and passing over the pulley, means for raising the logs, attached to said drum, and means for holding the logs elevated, substantially as described.

6. In a log-cart, the combination of a support mounted upon wheels, a drum rotatably mounted on said support, a lever rigid with said drum, a pulley on the end of said lever, a tongue slidably mounted upon said support, a flexible connection between the support and tongue and passing over the pulley, means for raising the logs, attached to said drum, means for holding the logs elevated, and means for holding said tongue from sliding, substantially as described.

7. In a log-cart, the combination of a support mounted upon wheels, a drum eccentrically mounted on pivots, a lever rigid with said drum, a pulley on the end of said lever, a tongue slidably mounted upon said support, a flexible connection between the support and tongue and passing over the pulley, and means for raising the logs, attached to said drum, substantially as described".

8. In a log-cart, the combination of a sup-- port mounted upon wheels, a drum eccentrically mounted on pivots, a lever rigid with said drum, a pulley on the end of said lever, a tongue slidably mounted upon said support, a flexible connection between the support and tongue and passing over the pulley, means for raising the logs, attached to said drum, and means for holding the logs elevated, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

ROBERT JOHUA WILLIAMS.
