FRED. O. KILGORF., OF MINNEAPOLIS@MINNESOTA, ASSIGNOR OF ONE-HALF TO JAS. F. WILLIAMSON, OF SAME PLACE.

STEAM Loic-LOADER.

SPECIFICATION'forming part of Letters Patent No. 420,942, dated February 11, 1890.

Application led December 31, 1888. Serial No. 295,041. (No model.)

for the purpose which shall be quick and ref liable in its actions. To this end I pivot the log-loading lever to a swinging mast and operate the lever by an engine directly connected thereto. The engine is controlled by a handlever within convenient reach of the operator. In this manner the most direct and the quickest action is obtained.

Iny the accompanying drawings, like letters referring to like parts throughout, Figure 1 is a side elevation of my invention in position for use. Fig. 2` is a plan view of the same, and Fig. 3 is a front view of the pivoted mast detached. I

A represents the basement, B the workingiioor, and C the ceiling or overhead framework, of an ordinary saw-mill.

Dis an upright post or mast pivoted so as to freely turn in the horizontal plane. As shown, this mast is composed of separate pieces d and d', securely bolted together at top and bottom through end blocks d d. There is thus left a clear space between the side bars CZ and d', which serve as a crosshead guide, as hereinafter stated. The upper end piece d is provided with a pintle E, adapted to engage with the socket or seat E in the overhead beam C. The lower end'piece cl" is provided with a hole through its vertical oenter. On the lower end of the mast surrounding its central opening is secured an annular metallic flange or bearing-plate F, cast integral with the block cl".

To the ioor B, in proper position to engage with the bearing-plate F, is secured a corresponding annular casting or base-plate G, having a vertical flange g. The mast rests upon the bearing-plate G below and is held from displacement by the pintle E and the 5o socket E above. Itis thus free to turn in the horizontal plane on these bearings as pivots.

H I-I are a pair of horizontal arms rigidly secured to the opposite faces of the mast D. 5 5 7i are braces for the same.

K is the log-loading lever. This is pivotally secured at about its central point by pivot-pin L, between the outer ends of the arms II H. The inner end of this lever is 6o approximately in line with the axis of the mast D. Its outer end is 'provided with a grappling device M, adapted to handle logs.

N is a cross-head movable between the bars d d as guides.

P is an upright slide-valve reciprocating engine located, as shown, in the basement A, directlyinline with the axis of the mast D. The piston-rod p of this engine passes up through the floorB and the hole in the end block of 7o v the mast D and is attached at its upper end to the cross-head N.

Q is a connecting-rod uniting the crosshead N and the inner end of the log-loading lever K.

R is a hand-lever pivoted to the floor B in convenient position for the operators use, and R is a connection from the same to the valve of the engine P.

S S represent logs, and T is one of the sup- 8o ports for the same.

Theoperation is evident from the description. The inner end of the log-loading lever being directly connected to the piston of the engine, is moved up and down at the will of the operator through the valve-operating lever R. This gives the necessary movement to raise or lower the logs. The mastD freely turns on its pivots, the piston of the engine turning within its cylinder, and this gives 9ol the necessary movement to swing the logs wherever desired in the horizontal plane.

It will be readily understood that the specie construction of the mast maybe different than herein shown. The engine might be also elsewhere located as long as the piston is directly attached to the log-loading lever.

I use steam as my motive power; but of course it` will be understood that air or liquid under pressure might equally Well be employed.

Vhat I claim, and desire to secure by Letters Patent of the United States, is as follows:

l. The combination, with a pivoted mast provided with vertical cross-head guides and a rigid horizontal arm, of a log-loading lever pivoted to said arm, a cross-head movable in said guides, an engine having its piston connected to said cross-head, and a connectingrod from said cross-head to said log-loading lever, substantially as described.

2. The combination, with a pivoted mast provided with vertical cross-head guides and a rigid horizontal arm, of a log-loading lever pivoted to said arm, a cross-head movable lengthwise of said guides,a reciprocating engine mounted in XeCl supports in line with said guides, having its piston connected to FRED.
