ROBERT G. MOON, OF VILLAGE MILLS, TEXAS.

LOG-CART.

SPECIFICATION forming part of Letters Patent No. 576,464, dated February 2, 1897.

Application filed J'unc 29, 1896. Serial No. 597,421. (No model.)

, will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying draw ings, which form a part of this specification.

My invention relates to improvements in that class of log-carts in which one end of the log is elevated or drawn up underneath the axle, while the other end drags along on the ground.

The object of the invention is to provide an improved construction of log-cart which shall possess superior advantages with respect to efficiency in operation.

The invention consists in the novel constructionand combination of parts hereinafter fully described and claimed.

In the accompanying drawings, Figure 1 is a longitudinal sectional view of a log-cart constructed in accordance with my invention. Fig. 2 is a plan view of the same.

In the said drawings the reference-numeral 1 designates the axle, 2 the Wheels of the cart, and 3 the hounds, which areconnected together at their front ends by plates 4, having a space therebetween for the passage of the sliding tongue 5, the rear end of which works in a slot in the axle and is held in place by a plate 6.

Secured to the axle, between the rear ends of the hounds, are beams 7, to which are sooured boxes 8, in which are journaled trunnions 9 of a block 10. This block is foursided,and two of its opposite sides are rounded, one being convex and the other concave, as seen at 12 and 13, while the other sides are hat.

The trunnions are secured eccentrically to the block, that is to say, near one corner at each end, and at the center, on the convex side, the block is provided with a post or bar, by which it may be turned or rotated. Secured to the outer end of said bar is a chain 14, to the other end of which is secured the sliding tongue in front of the hounds.

The numeral 15 designates a catch pivotally connected with said bar, which is adapted to engage under a transverse bar 17, secured to the hounds, and hold the block in place when it has been turned to elevate a log. Connected with this catch and the bar is a coiled spring 16 for forcing the end of the catch under the bar.

Secured to the upper plate 4:, at the front ends of the hounds, are two lugs 18, to which is secured a rod 19. Pivoted to this rod is a gravity-dog 21, having its front end turned down at an angle and adapted to engage with teeth 23 of a rack-bar 24, secured to the tongue. To the other end of this dog is journaled a roller 20, under which the chain 14 passes.

Pivoted to the bar secured to the block is a pin 25, which is adapted to fall by gravity when the said bar is turned down to elevate the log and engage with a slot 26 in the tongue.

The numeral 27 designates grab-chains secured to the block, by which the log is elevated.

The operation is as follows: The block is turned backward, so that the bar secured thereto will occupy a perpendicular or vertical position, and the beam is hitched to the tongue. The chains 27 are then connected with the end of the log to be elevated and the team started, which will draw the tongue outward, turning the bar and block and raising up the log. At the same time the dog 21 will engage with the teeth of the rack-bar and by the pressure of the chain 14 thereon will relieve the team of the backward strain. As the chain assumes a horizontal position the pivoted pin 25 will swing down and engage with the slot 26 in the tongue, and thus take the strain ofi the chain when the cart is moved. The spring-catch will also engage with the transverse bar to hold the bar and block in position.

Having thus fully described my invention, what I claim is- 1. In a log-cart, the combination, with the axle, the slidable tongue, the block, the trunnions and the bar, of the lugs secured to said tongue, the dog pivoted thereto having its front end bent downwardly, the roller journaled to the other end of said dog, the chain secured to said block, passing between said roller and pawl and pressing upon the front end of the dog and secured to the tongue and the rack-bar secured to the tongue, substantially as described.

2. In a log-cart, the combination with the axle, the hounds the slidable tongue having a slot therein, the block having trunnions cccentrically secured thereto, and the bar, of the chain secured to said barand tongue, and the pin pivoted to said bar and adapted to engage with the slot in the tongue; substantially as described.

In a log-cart, the combination with the axle, the slidable tongue having a slot therein, the hounds, the plates conn ectin g the hounds,

the beams and boxes; the block having trunnions eccentrically secured thereto journaled in said boxes, the bar secured to said block having a pivoted pin and a spring-catch, the chain secured to said bar and tongue, the lugs, the pulley, the pivoted dog having its free end bent at an angle, and the rack-bar secured to the tongue; substantially as described.

In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.
