FREDERICK F. SOI-IOFIELD, OF ASCODA, MICHIGAN.
SPECIFICATION forming part of Letters Patent No. 309,103, dated December 9, 188%.
Application filed May 2!), 1883.
1' 0 rtZZ whom it may concern:
Be it known that I, FREDERICK F. Sono FIELD, of Aseoda, county of Iosco, State of Michigan, haveinvcnted a new and useful Int provenient in Log-Loaders; and I declare the following to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawingspvhich form a part of this specification.
My invention consists in the combinations of devices and appliances hereinafter speci-- lied, and more particularly pointed out in the claims. I
In the drawings,Figure l is a plan View of an apparatus embodying my invention. Fig. 2 is a side elevation. Fig. 3 is an end elevation of a portion of the same. Fig. 4 is a separate view of one of the parts.
The object of my invention is to provide an improved log-loader, adapted to loadlogs onto a carriage commonly employed in saw-mills, which shall be capable of ready and easy operation.
I accomplish my object as follows:
As illustrated in the drawings, A represents the ordinary carriage.
13 represents the frame in which the circular saw is engaged.
0 represents the floor.
1) represents the nigger.
E is the skidway of my improved loader.
F is an operating shaft or roller beneath the floor, said shaft or roller adapted to be driven by friction or other means.
f represents a crank or eccentric at the ends of the operating-shaft.
G represents conuecti ng-bars secured to said cranks or eccentrics at their lower extremities.
H represents a cant lever or bar ofsuitable form, preferably constructed as shown in Fig.
4, having a toe-piece, h, and an angular arm, H, the extremity of said arm being hinged or pivoted to the upper extremity of the connecting-rod. The cant-lever is pivoted in the skid (X0 model.)
way, as shown in dotted lines in Fig. 2.
It is evident that when the toe of the lever projects and the angular arm is depressed to thelevel of the surface of the skidway the toepieces will hold the log in place; but when the operating shaft or roller is rotated, so that the too is depressed and the angular arm elevated, the log resting upon the cant-lever and held in place by the toe-pieces will be projected downward upon the circular carriage. The length of the cant-lever is such that as one log is projected forward oif the skidway the an gular arm will be projected between it and the following log in such a manner that but one log will be loaded upon the carriage at a time. The continued rotation of the operating-shaft will again depress the angular arm and elevate the toe of the cant-lever, thus letting the log forward upon the face of the cant-levers,where it will again be held in place by the elevated toes.
two timbers on each side,so that the cant-lever can be pivoted between them, though said levers may be pivoted to the skidway in any suitable manner.
The friction of the rollerl, by which the op eratingshaft is rotated, may be controlled in any proper manneras, for instance, .by the lever Iand said friction-roller may also operate the nigger in any ordinary manner.
\Vhat I claim is- 1. In device for rolling logs from a skid to a saw-carriage,a series ofrocking arms mounted on a transverse shaft connected to said skid, in combination with a pulley rotatable at will, and a .rod connecting the pulley to at least one of said rocking arms,substantially as set forth.
2. The combination, with the skidways E and log-carriage A, of the cant-levers H, pivoted to rock in a vertical plane, and each constructed at one end with the toe-piec-e h, and at the other end with a depending angle-arm,- H, the rods G, pivoted at one end to the said angle-arms, and the shaft F, having crankarms f pivoted to the lower ends of the rods, substantially as described.
3. The combination, with the skidways E and log-carriage A, of the cant-levers H, di-
I will be projected above the surface of the skid The skidway is preferably constructed of reotlypivoted on the skidways, and each havpivots, and each provided with a toe-piece, h,
ing at one end the toe-piece h, and at the other and a depending angle-arm, H, and devices end the depending angle-arm H, the rods G, I connected with said levers to rock them in a pivoted at one end to the depending anglevertical plane, substantially as described.
5 arms, and the shaft F, having cranlcarms f In testimony whereof Isignthisspecification pivoted to the other end of the said rods, subin the presence of two witnesses. stantially as described. FREDERICK F. SOHOFIELD.

It is hereby certified that the residence of the patentee of Letters Patent No. 309,103, granted December 9, 1884, upon the application of Frederick F. Schofield, for an improvement in Log-Loaders, was erroneously Written and printed Ascoda; that said residence should have been written and printed Oscoda; and that the proper correction has been made in the files and records pertaining to the case in the Patent Office, and should be read in the Letters Patent to make it conform thereto.
