IMPROVEMENT IN MACHINES FCR MOVINGLOGS.

specification forming pm of Leners Patent Noflssrs, dated June 3, 1873 application inea February 1, 1573.

To all whom it may concern:

Be it known that we, GEORGE M. HINKLEY, of Milwaukee, in the county of Milwaukee and State of Wisconsin, and ALEXANDER RODGERS, of Muskegon, in the county of Muskegon and State of Michigan, have invented a new Improvement in Machines for Moving Logs, of which the following is a specification Our invention is an improvement upon the log-turnin g machine patented to A. RODGERS March 1-9, 1872, No. 124,763, and consists in the application of a jointed push-bar and certain actuating devices to the turning apparatus heretofore used for turning. logs on the carriage, and whereby the logs may be rolled from the log-way Onto the carriage ot' a sawmill by power, all as hereinafter more fully described.

Figure lis a side elevation of the apparat-us, together with part of a carriage log-way and some logs, which are indicated so as to show the relation of the said apparatus with the log-way and carriage. Fig. 2 is partly a front elevation and partly a section; and Fig.

3 is a plan view.

Similar letters of reference indicate corresponding parts.

A represents the log-turning bar, heretofore used for turning logs in the position indicated at B.' on the carriage C, the said bar being provided with spikes D on the side fronting the log to hook into it when pushed upward, for which suitable apparatus is provided.

Now, we propose to utilize this bar for rolling the logs onto the carriage also; and ,we therefore apply the push-bar E to the top of it between platos or bars F, inA which it is pivoted at G, so that it will swing down as indicated at H, and pass under the logv readily when the bar A is swung backward along the logway 1,"for the purpose of engaging the logs rightly for pushing them forward onto the log-way. One end of this push-bar is made heavier than the other, so that, after passing under the log, it will rise up behind the log, as represented at K, to force the log along when the arm A is moved forward toward the carriage C. For swinging the arm A forward and back in this Way, We connect it by a clip, L, with cross-head M, arranged in horizontal ways N, on a strong frame, O, having a slot, P, in which the arm swings'and is guided; and the cross-head we connect to arod, Q., extending along between the ways through the frame at the end of the slot. We also connect it to a chain, T, which passes along under the rod to and over a chain-drum, U, at the end of the frame; thence down around a driving chain-drum, V, and.- up over drum U again; and thence to the outer end of rod Q, to which it is connected so as to move the said rod,the cross-head, and the bar A in either direction according to the way the driving drum V is turned; and for turning said drum we provide a reversing drivin g-gear cofsisting of the frictionl bevel-wheel W, friction pinionsX, counter-shaft Y, and the belt-pulley Z; the said counter-shaft being turned constantly "in one direction, but is capable Spf shifting endwise to` bring either pinion into gear with wheel W or disconnect them both; and is provided with a shifting-lever, Z', for

so shifting it. Thus the bar A can be readily swung back under the logs behind them, the push-bar caused to engage the log, and the bar A forced forward again by power applied tothe rod Q, and the log rolled on the car riage. f

It will be observed that after the push-bar has passed under the log and swung up into the working position, the lower arm comes against the top of arm A, or a pin thereon, and holds the upper arm inthe proper position for applying the power. A

It will also be observed that the clip L en gages the bar AY by the projecting edges of a thin metal bar, a, bolted on to the side of 2A, to allow it to rise and fall freely in swingijatg forward and back; also in turning the log.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent, is g 1. The bar A having the pivoted and weighted push-bar E arranged on it, in th manner shown and described.

2. rPhe combination of the bar A and its actuating devices, in the manner and for the purpose specified. y

3. The combination of the crosshead M, rod Q, ways N,'chain T, and chain-drum U, and the drivingdrum V, and the reversing driving gear, substantially as specified.`
