Letters Patent No. 103,608, dated May 31, 1870.

IMPROVED LOG-LQADER.

The Schedule referredto in rthese Letters Patent and making part of the saine.

To all whom Vit may concern.-

Be it known that I, JOHN H. HARVEY, of Chanticleer, in the county of Knox and State of Ohio, have invented a new and improved Log-Loader; and I do hereby declare that the following is a full, clear, and exact description thereof', which will enable others -skilled in the art to make and usethe same, reference being had to the accompanying drawing forming part of this specification.

The object of this invention is toprovide elcient.

means for loading or rolling logs or other heavy weights, (more especially 'sawlogs;) and It consists in revolving a drum or cylinder on an adjustable frame by means oi' a ratchet-wh eel and p'awllever and stop-pawl, so arranged as to be readily thrown out of gear with the ratchet-wheel, for gigging back and operating, as hereinafter more fully described.

In the drawingl Figure 1 is a vertical section of the machine, looking to the left from the Vline :t :t of iig. 2.

Figure 2 is a side elevation, partly in section. y

Similar letters of reference indicate corresponding parts.

A is the base or bed-plate, to which are rigidly attachedthe two slotted stands B and C.

D is a frame, made adjustable, as to height, between the stands'B and O by means of the rods E, clasps F and nuts G, ass'een in iig. 2.

H is the drum or'cylinder, which is made to revolve on journals in the adjustable frame D;

I is a ratchet-wheel, rigidly attached to the end of the drum. I

J is the lever, which works on the journal of the -drum between the-end of the drum and thc frame D.

K is the -working-pawl attached to the side of the lever, but having a loop, L, jutting over the top of the M is a spring attached to the top of the lever, passing through the loop, with a slight circular indentation, which-sits on the base of th'c'loop and serves to hold the pawl to its work when engaged with the ratchet.

N' is `the holdingpawl,.,which is attached to the' frame D andheld to its work by aspring, o.

A rope or chainr is fastened to the drumrand made to operate upon a log 'orother heavy body by menus of the lever working up and down.

For producing a reverse motion of thedrum or lgigging back wit-hout loss of time, I throw'the working-l `pawl K ont of 'gear with the ratchet by pushing its upper end or loopL forward, which throws its toe back from theratchet, in which position the pawl is held by the spring M. y

The holding-pawl N is thrown out of gear by means of the lever P, the ends of which are4 turned at right angles with the lever in opposit-erdirections.

This lever is pivoted to the frame at q.

W hen the end It is raised, the other end S, (see fig. 2,) will .crowd the pawl N from the ratchet-teeth.

The lever P is held in this position by the loose rod T, through which is madeone or more holes by means,

of which the rod is'connected with the lever, and held in the desired position. Y

lVhen. the pawls are thus thrown ont of gear with the ratchet, t-h'e drum is left free to revolve by simply pulling the rope for giggingback.

lHaving thus described my invention,

I claim as new and desire to secure kby Letters Patent- -1. The pawl Kl and spring M, arranged and operating as described, for the purposes set forth. 2. In combination with the holding-pawl N, the bar P and rod T, by means of which said pawl is held out oizgear, substantially as described.

3. The combination of the bar P, rods T, pawls K and Nwith alog-loader and roller, when the same are arranged to operate substantially' as described, and for the purposes set forth.

' JOHN H. HARVEY.-
