UNITED STATES DANIEL W. GLASCOCK, 0F STOCKTON, CALIFORNIA.

LOGGING DEVICE.

Application filed December 27, 1921.

To all whom it may concern:

Be it known that I, DANIEL W. GLAsoooK, a citizen of the United States, residing at the city of Stockton, county of San Joaquin, and State of California, have invented new and useful Improvements in Logging Devices, of which the following is a specification.

This invention relates to a logging device and has particular reference to a low tractor logging wheel device equipped with novel means for lifting and holding logs of varying diameters.

The primary object of this invention is to provide a device of the character described so constructed as to operate in confined places or on rough hilly ground whereby I attain high clearance on a low axle construction.

An additional object is to provide a novel type of main frame adapted to support the axles of the device with the axle so supported from both sides that the danger of the axle breaking is reduced to a minimum.

A furtherv object of this invention is to provide a device of the character described, which is comparatively simple in construction, inexpensive to manufacture, positive in action and highly serviceable and efficient in use.

Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification, and in which like characters are employed to designate like parts throughout the same Fig. 1 is a side of my tractor logging wheeled device.

Fig. 2 is a section on line 22 of Fig. 1.

Fig. 3 is a top plan view of the device.

Fig. 4 is a sectional View on line YY of Fig. 3.

.Among other elements my improvement comprises a tongue A, arranged between inner rearwardly extending rods B and outer rearwardly and downwardly extending rods B each of the said rods comprising threaded sections as illustrated joined by a turnbuckle B. The outer downwardly and rearwardly extending rods B afford bearings M for the outer ends of the axles P of wheels O.

The main frame of the machine is made preferably of structural steel and includes Serial No. 525,202.

a beam D to which the rear ends of the inner rods B are connected as shown in Figures 1 and 3. Sand frame also includes two plates R, fixed to said beam D, forming an arch and trussmg the mam frame and affording bearings for the inner ends of the axles P, as shown 1n Flg. 2.

These plates R are spaced apart the proper distance to allow a lifting chain S to pass freely up and down through guides T at the lower ends of the plates R. Said guides serve to receive and maintain in spaced relation the pendent portions of the chain S, and thereby operate to keep the. chain in place, and also to provide means for fastening the axles P at or near the lower ends of the plates R as shown in Fig. 2.

On the ends of the beam D are pendent brackets B extending down to and receiv ing the outer portions of the axles P to rigidly support the same as shown in Fig. 2.

Fixed to and extending forwardly from the beam D are hounds J which serve to brace and lend increased strength to the main frame. These hounds are fixedly connected at their forward ends to a cross member 20 which cross member forms a guide 21 for the tongue A as shown in Figure 4 and also serves for the connection of the forward ends of the rods B and B. In virtue of the said rodsv including turnbuckles B as described, the machine may be adjusted to any position forward or back, so as to balance the load for any height of tractor.

On the top of the beam D are six bracket bearings, the inner bearings G having antifriction rollers G" placed at such a position as to allow the tongue A (see Fig. 1) to pass through under them freely. Carried by the beam D and disposed under the tongue A is an anti-friction roller D. (See dotted lines in Figure 2.)

Journaled in the bearings G is a shaft H with a spur gear I keyed or fastened in its center as shown in Fig. 2.

On top of the hitch tongue A is a rack A with teeth engaging with the gear I, as shown in Fig. 1, the object of the same being that when the tractor moves forward the rack on the hitch tongue A (Fig. 1) will also move forward, causing the gear to rotate turning the shaft, thus winding the chain, which is arranged to wind up on said shaft, causing the logs around which the chain has been locked, to be lifted from the ground as shown in Fig. 2.

Carried by a rear pendent portion 30 on the tongue A is a buffer 31, opposed to the rear side of the beam D and yieldingly maintained in the position illustrated through the mediumof a coil spring 32 mounted on the buffer and interposed between the said rear portion 30 and the head or forward enlargement of the buffer. Manifestly the said buffer will serve on forward movement of the tongue A relative to the main frame of the apparatus to bring up against the rear side of the beam D and thereby absorb shock and ar.

From the foregoing description considered in connection with the accompanying drawings, it will be evident that I have de vised a highly efficient device that will serve to lift and hold a plurality of logs of varying diameters.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

Having described my invention, what I claim and desire to secure by Letters-Patent,
