LOGGING-CART.

Specification of Letters Patent.

Patented June 23, 1908.

Application filed February 18, 1908. Serial N 0. 416,473.

T 0 all whom it may concern:

Be it known that I, THOMAS A. L. STRANGE, a citizen of the United States, residing at Thrasher, in the county of Prentiss and State of Mississippi, have invented a new and useful Logging-Cart, of which the following is a specification.

This invention relates to logging carts and is more particularly designed as an improvement upon the truck described and claimed in Patent No. 801,415, granted to me on Oct. 10, 1905, and upon various other forms of carts of this character designed to partly support and drag logs over the ground. Carts of this character are provided with arches extending upward from the axis of the wheels and the logs are raised by means of various devices so as to be supported at their forward ends within these arches. The entire weight of the forward portion of the log is thus supported by the upper portion of the arch. It has been found in practice, however, that when the cart is pulled forward, the frictional contact of the rear portion of the log with the ground results in the upper portion of the arch being pulled backward, this resulting in a corresponding upward movement of the tongue to which the draft animals are connected. This is very undesirable because of the additional strain upon the draft animals which is produced.

The object of the invention is to provide an attachment for carts of this character whereby the means for lifting and supporting a log within'an arch is utilized solely for that purpose and not for the additional purpose of pulling the log, there being separate means employed for dragging the log, said means being so mounted that the pull will be exerted from the axis of the cart so that it will not result in the tilting of the arch and a corresponding movement of the tongue.

With these and other objects in view the invention consists of certain novel features of construction and combinations of parts -which will be hereinafter more fully described and pointed out in the claims.

In the accompanying drawings is shown the preferred form of the invention.

In said drawings: Figure 1 is a perspective view of a cart. embodying the present improvements, portions of the lifting and supporting mechanism being illustrated. Fig. 2 is a plan view of the parts shown in Fig. 1, the arch being partly broken away. Fig. 3 is an inner elevation of a portion of the arch of the cart. Fig. 4 is a detail view of the tightening means employed in connection with the dragging chain.

Referring to the figures by characters of reference, 11 designate the wheels of the cart the same carrying spindles 2 located at the lower ends of a central arch 3 there being forwardly extending beams 4 at the ends of the arch which constitute hounds and are parallel to each other, the forward ends of these beams being connected by a cross beam 5 to which the tongue 6 is suitably attached. Tongs 7 are su orted within the arch by means of a flexible hoisting element such as a chain 8 but inasmuch as this hoisting mechanism constitutes no art of the present invention it has not been r escribed or shown in detail. The hoisting and supporting mechanism employed may be the same as that covered by my patent heretofore mentioned or it may be of any other form desired.

As heretofore stated when a cart provided solely with means for supporting a log is drawn forward the resistance roduced by the contact of the rear portion 0 the log with the ground results in a backward pull on the upper portion of the arch, thus causing a corresponding upward movement of the tongue. To eliminate this objectionable feature an attachment has been provided which consists of a chain 10 the ends of which are secured to grooved spools or winding devices 11 mounted upon pivot bolts 12 detachably connccted to and extending inwardly from the side portions of the arch 3 at points concentric with the wheels 1. Each of these spools has an operating lever 13 fixedly connected to it and provided with a hook 14 designed to be swung downward-and placed into engagement with the adjoining portion of the chain 10 as indicated particularly in Figs. 1 and 3. As shown in Fig. 1 this chain 10 is extended through a pulley 16 to which a supplemental chain 17 1s connected. This supplemental chain may be of any desired length and has a hook 18 detachably connected to it and designed to be attached to any one of the links of the chain.

It is believed that the operation of the device will be fully understood from the foregoing descri tion. Before the front end of the log has been raised and secured Within the arch chains 10 and 17 are extended over the log and the hook 18 is placed in engagement with said supplemental chain and with the end of the log, after which chain 10 is drawn taut in the manner hereinbefore described. After this dragging attachment has been placed in engagement with the log the log can be raised and secured within the arch in any desired manner.

When the car is drawn forward the chain 10 pulls forward upon the rear end of the log, the line of draft extending from said log end to the spools 11. It will thus be seen that the upper portion .of the arch is relieved of all strain due to dragging and the danger of tilting the arch as a result of the dragging operation is fully eliminated and the lifting and holding mechanism is relieved of al backward pull due to the frictional contact of the log with the ground.

It is of course to be understood that cables or other flexible elements may be utilized in lieu of the chain shown and described and various other changes may be made without departing from the spirit or sacrificing the advantages of the invention.

As shown in Fig. 3 a bolt opening 19 may be formed in each side of the arch and above thelower or normal position of the s 001 11. The pivot bolt 12 of the spool can t erefore be inserted within the opening 19 so as to raise-the spooland enable the backward pull exerted b the dragged log to equalize or counterba ance the weight of the hounds and toggue.

though two s ools have been shown Within the arch an the chain has been described as having its two ends fastened to them it is to be understood that if preferred only one spool can be employed.

By utilizing the su plemental chain and its pulley connection, ateral swinging of the log relative to the cart is ermissible when turning the cart, because t e pulley will be free to travel along chain 10 as is obvious.

What is claimed is:

1. A device of the character described comprising an arched axle, supporting wheels therefor, means for supporting one end of a log within the arched axle, and means connected to said axle for exerting a draft upon the rear end of the log from the axis of the axle.

2. A device of the character described comprising an arched axle, supports therefor, means for supporting the rent portion of a log within the arched axle, and dragging -means extending-from the axis of the axle gaging the rear end of the log, said means extirliding toward the log from the axis of the a e. 1

4.- A device of the character described comprising an arched axle, su porting means therefor, means for securing tiie raised end of a logwithin the arch of the axle, and means u on the axle for engaging a log to revent t ting of the axle by the dragging of t e log.

5. A device of the character described com risin an arched axle, a support therefor, oun s extending from the axle, means for holding the raised end of a log within the arch of the axle, a spool carried by the arch, and flexible-draggin means secured u on the spool for engaging the rear end of the 0g.

6. A device of the character described comprising supporting wheels, an .arched axle carried thereby, means for securing the front end of a log within the arch of the axle,

.and dragging means connected to the axle and extending from the sides of the arch at the axis thereof for engaging the rear end of said log.

7. A device of the character described comprising supporting wheels, an arched axle carried thereby, means for securing the front end of a log Within the arch of the axle, Winding means carried by the arch near the axis thereof, and a flexible log engaging device connected to and disposed to be drawn taut by the winding means.

8. A device of the character described comprising supporting wheels, an arched axle carrled thereby, means for securing the front end of a log within the arch of the axle, and dragging means connected to the axle and comprising winding means supported by the axle near the axis thereof, a flexible log engaging device secured to said means, and a retaining device carried by said means for enga ement with the flexible device to hold said evice wound u on said means.

9'. A device of t e character described comprising supporting wheels an arched axle spool, a lever carried by the spool, an means upon the lever for engagin the flexible device to hold it wound upon t e spool.

10. A device of the character described comprising supporting wheels, an arched axle carried thereby, means for securing the front end of a log within the arch of the axle, and dragging means connected to the axle and comprising a flexible element, means for adjustably connecting said element to 'the arch, a pulley mounted upon said element, a supplemental flexible element extending from said pulley, and a log en aging device car- 10 ried by the supplemental e ement.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two Witnesses.
