Letters Paten-t N o. 106,160, dated August 9, 1870.

. the county of Erie and State of Pennsylvania, have `invented a new and useful Improvement in Log- Turner; and I do hereby declare that the following is a .full,. clear, and exact description thereof, which lwill `enable others skilled in `tle art to make and use the same, reference being had jto the accompanying drawing forming part of this specification, in which--l Figure l is a front view of my improved log-turner.

' Figure 2 is a rear view of the same.

M y'invention nas for its object to furnish a simple, convenient andi/effective device for turning .logs and other timber upon the carriage oi'a saw-mill and It consists in the construction and combination of the various parts of the device, as hereinafter more fully described. 'r

A represents the frame, .B the way, and G the carriage of-a saw-mill, about the construction of which parts there-is nothing new.

D are two uprights, suspended from a cross-beam, a', of the frame A, in such a waythat their lower ends may swing toward and from the log upon the carriage O, and which` are :held forward against said logr by springs E, attached to the posts of the frame A, or to some other suitable and convenient support, and lwhich press against the outer sides of the said suspended bars D; or, if desired, the bars D may he held forward to their places by weights.

To the lower ends oththe bars D are pivoted two spur-wheels, F, in suclijpositions that their teeth may bear against and take'hold of the opposite sides of the log or vother timber upon the carriage C.

'Ihe journals of the spur-wheels F pass through the lower ends of the bars D, and to their other ends are scribed, and for the purpose set i attached small bevel-gear wheels G, the teeth of which mesh into the teeth ofthe small bevel-gear wheels H, att-achedl to the lower ends of the shafts I. The shafts I extend up along the sides of the bars D, and revolve in bearings attached to said bars.

To the -upper ends of the shafts I are attached small beveled gear-wheels J, the teeth of which mesh into thetceth of the small bevel-gear wheels K, attached jo'urnals pass through and work 4in bearings in the upper ends of the bars D, or iu the studs or other supports from which saidbars are suspended.

The pulleys L are connected with a band, M, so that they' may both revolve together.

4Power may be applied to one or the other of the pulleys L by a crank, N, or by any other of the wellknown means for the application of power. The device may be operated by hand power, or by the power that ope-rates the mill.

By this construction, when power is applied t0 the device, the spur-wheels F will ac t upon the log or timber upon the carriage G, and will revolve the log or timber in one or the other direction, according to the direction in which the power is applied.

Having thusdescribed my invention,

I claim as new and desire to secure by `Letters Patent- The combination of the swinging bars D, weights or springs E, spur-wheels F, bevel-gear wheels G H, shafts I, bevel-gear wheels J K, pulleys L, and band M,- wit-h each other, and with the frame and carriage of the saw-mill, substantially as herein shown and deorth.
