UNITED STATES PATENT OEEICE.

WILLIAM E. HILL, OF KALAMAZOO, MICHIGAN.

LOG-TURNER.

EBPEGIFIGATION forming part of Letters Patent No. 315,032, dated April 7, 1885.

Application Elcd August 18, 1884. (No model.)

To all whom'it may concern:

Be it known that I, WILLIAM E. HILL, a' citizen of the United States, residing at Kala- Inazoo, county of Kalamazoo, State of Michi gan, have invented a new and useful Gant- Machine, of which thefollowing is a specification.l

This invention has for its object certain improvements in such devices, hereinafter described and claimed. In the drawings forming a part of this specification, Figure l is a side elevation and a sectional view of a mill-floor, and Fig. 2 is an elevation looking from a point at the right hand of Fig. l.

The engine B is pivotally supported at the lower end, the supporting-plate in which the pivot or axis has its bearing being provided pivoted cant-leversf maybe used.

with an opening beneath the engine to allow the latter to tilt on its pivot.

A is the mill-floor above the engine B, on which are located the roller-platforms P D a.

The device as here shown is used to throw slabs, logs, boards, or scantling, or cants` 85o., from the rollers a a onto the rollers D, which latter-named rollers convey it to the rollers I?. The rollers Ilconvey it to other locations in the mill-as, for instance, if sawed lumber n previous to edging, the rollers P convey the same to an edging-saw. One or more of the In Fig. 2 a number are shown.

E is a rocking shaft provided with arms fu c, one or more, according to the number of cantlevers f used. The rocking shaft E is provided wit-h an arm, fo, which is pivotally connected with the piston y of the engine B. The cant-levers f are connected with the arms o v of the shaft E by means of bars c, pivotally connected with said arms and levers.

In the operation, when the piston y rises, the rocking shaft turns, raising the cant-levers f to the position shown in dotted lines in Fig. l. In this figure the lever f has raised a slab, n', in the act of landing it onto thefrollers D.

In Fig. 2 an automatic throttlelever, e, is shown. In this connection the rollers a a represent a transfer mechanism propelled by machinery. (Not here shown.) In some mills an endless-chain carriage is used in lieu ofthe rollers a a. The' automatic throttle-lever e may be used with, and means of, transferring or moving lumber in the relation here shown.

The lever e is centrally pivoted to a bellcrank, y', and the lower endis connected with the throttle of the engine by means of rods t u and a bell-crank, d. The upper end of the lever e is extended above the upper plane of the transfer a a. By this means, when moving lumber n comes in Contact with the lever e, the throttle is automatically opened and the cant-levers -set in operation to throw the lumber onto other transfer devices, carriages, or skidways, as thecase may be, or, in the absence of any of these, to throw the lumber into a pile onto the floor.

A lever, r, is connected with one arm of the belllcrank y by means 0f a rod, S, by which means the throttle-lever e may be thrown down to allow the lumber to pass on when not desiring to use the cant-levers.

Having thus described myinvention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a cant-machine, the combination of the rock-shaft provided with an arm for piv-l otal connection with the engine piston and with arms for connection with the cant-levers, cant-levers pivoted at one end, and bars pivotally connecting the arms of the rock-shaft with the free ends of the cant-levers, substantially as set forth.

2. The combination of the engine, cant lever or levers, a suitable lumber-transfer device,andacentrally-pivoted throttleleverhaving one end extended beyond the plane of the transfer device and the other end pivotally connected by suitable means with the enginethrottle, for the object stated,all substantially as set forth.

8. The combination of the engine, cant lever or levers, a suitable lumber-transfer device, a throttle-lever centrally pivoted to a bell-crank and having one end extendedV beyond the plane of the transfer device, suitablemeans pivotally connecting the other end with the engine-throttle,a pivoted hand-lever, and a rod pivotally connecting said hand-lever and bell-crank, all substantially as set forth.

In testimony of the foregoing I have hereunto subscribed my name in the presence of two witnesses.

WILLIAM E. HILL.
