LOG-CART.

Specification of Letters Patent.

Patented May 21, 1907.

Application filed September 1,1906. Serial No. 332,937,

To aZZ whom it may concern.-

Be it known that I, JAMEs ALBERT PERRY, a citizen of the United States, and a resident of Burgaw, in the county of Fender and State of North Carolina, have invented an Improvement in Log-Carts, of which the following is a specification.

My invention is an improvement in that class of log carts or carriers in which the log is suspended from an axle by means of chains.

have devised certain improvements which are hereinafter described and illustrated in the accompanying drawings, in which Figure 1 is a side elevation of my improved log cart or log carrier, save that one of the transporting wheels is detacheda log being shown suspended and elevated in the position required for transportation. Fig. 2 is a plan view of the log cart. Fig. 3 is a rear end view of the log cart, save that the tongue is shown in section. Fig. 4 is a side view of the log cart-save that one wheel is detached showing the parts in the position they occupy before the log is lifted.

An arched axle 1 having a bolster 2 is pro- 'vided with two running wheels. A bar 4 forms the main portion of the upper side of the bolster 2, and it is secured in place by two loops 5 in clevis form. A pole or tongue 6 is pivoted at 7 between the front ends of hounds, or curved side bars, 8see especially Fig. 2and the rear end of the tongue extends over the bar 4 between brackets 9 which are secured to the bar 4 by means of the clevis loops 5, their upper ends being curved outward in order to facilitate guiding the tongue 6 between them, as will be presently described. A spring latch 10 passes through one of the guides 9 and also through a supporting bracket 1 1, a spiral spring being interposed between the guide and bracket as shown in Figs. 2 and 3. A short handle 12 is attached to the outer end of the latch 10 for use in withdrawing it against the tension of the spring. The inner beveled end of the latch 10 projects over the tongue 6 when the latter is in normal position, as in Figs. 1, 2, 3. A log chain 13 is attached at one end to a hook or eye 14 at one end of the bar 4, and the other end of said chain is detachably connected with a hook 15 at the opposite end of said bar. Another chain 16 is attached to the front side of the bolster 2 and connected at its opposite end with the tongue 6 at a point just in rear of the front portions of the hounds 8. The function of this chain will be presently explained.

A doubletree 17 having singletrees 17 attached is connected with the tongue at a suitable point in front of the wheels 3 and a neck yoke 18 is also arranged at the end of the tongue in the usual way.

l/Vhen loading, having placed the cart over the log and released the tongue by pulling the latch 10, the team is backed slightly which causes the axle to rotate and the hounds and tongue to rise, or, in other words, the top of the bolster rotates backward toward the log. The chain 13 is then slipped under the log and hitched to the hook on the other side of the bolster. Upon driving the team forward the tongue and hounds come down into nearly horizontal position as shown in Fig. 1, which is the normal one. In other words, the bolster and axle rotate forward or from the rearward incline to afivertical position, so that the log is drawn upward or raised from the ground. This operation requires but a few seconds. It will be seen that when the tongue, bolster and axle assume the normal position shown in Fig. 1, the tongue reengages with the latch 10 automatically.

To unload, that is to say, to release the log, the free end of the log chain 13 is detached from the jumpor snatch-hook, which may be effected by the driver taking hold of the loose or slack end of the chain and giving it a quick jerk. It will be seen that the function of the chain 16 before described is to prevent the tongue 6 and the hounds, bolster, and axle from assuming a different angle to each other from that represented in Fig. 4. In other words, the chain serves as a stop to limit the swinging movement of the tongue 6 in the hounds 8 and through the medium of the tongue and its connection with the team, it is held in the loading operation about the angle represented in Fig. 4, the bolster and axle being in such case inclined rearward a little above the horizontal.

It will be seen that nothing is required in order to release the tongue from the bolster and axle save to pull the latch 10 outward, and that the re-engagement of the tongue with the latch is effected automatically as the team moves forward after the log chain has been passed around the log.

It will be noted in Fig. 3 that the hounds 8 lie between the ends of the bar 4 and upwardly projecting ears forming portions of the bolster 2. The hounds are permanently and rigidly connected with the bolster so as to swing or move with it.

While I prefer to employ a curved axle as shown, it is obvious that a straight one may be used in place of it.

It is further apparent that it is not absolutely necessary that the bolster shall be rigidly connected with the axle nor that the latter shall rotate with the bolster since the same result may be attained by arranging the bolster loose on the axle so as to rock thereon, the main feature of the invention being the pivotal connection between the tongue and hounds, or any form of rigid arms suitably connected with the axle so as to serve practically as a rocking lever.

What I claim is 1. The improved log cartcomprising an axle, transporting wheels, a bolster applied to the axle, a log chain connected with the bolster, hounds projecting forward from the latter, a tongue pivoted to the hounds, and means on the bolster for locking the tongue detachably therewith in the normal position, substantially as described.

2. The improved log cart comprising an axle, transporting Wheels, a log chain, hounds projecting forward, a tongue pivoted between the hounds, and a stop chain connecting the rear portion of the tongue with the axle whereby the swinging movement of the two is arrested, or prevented exceeding a certain angle in the loading operation, substantially as described.

3. The improved log cart comprising an axle, transporting wheels, and a bolster secured to said axle, hounds extending forward, a tongue pivoted between the hounds, guides secured on the bolster and adapted to receive the rear portion of the tongue between them, and a locking device for engaging the tongue and holding it in normal position, substantially as described.

4. The improved log cart comprising an axle having transporting wheels, a bolster secured to the axle, hounds extending forward from the bolster, a tongue pivoted between the front ends of the hounds and extending rearward over the bolster, and a lock ing device secured to the bolster and adapted for automatic engagement with the tongue, substantially as described.

5. The improved log cart comprising an axle, transporting wheels, a bolster applied 7 to the axle, hounds secured tothe bolster, a

tongue pivoted between the front ends of the hounds, a slidable spring-actuated latch having its inner end beveled, and guides for supporting the latch whereby, when the tongue is drawn down into the normal position, it automatically engages the latch, substantially as described.

6. The improved log cart comprising an axle, a bolster secured thereto, a bar clamped on the bolster, hounds whose rear portions lie in spaces between the ends of said bar and adjacent ears, or projections, of the bolster, a tongue pivoted between the front portions of the hounds, and a log chain attached to the said bar, substantially as described.
