IMPROVEMENT IN STOCK- GALLOWS.
Specification forming part of Letters Patent No. 178,931, dated J une 20, 1876; application filed February 24, 1876.
To all whom it may concern:
Be it known that 1, WILLIAM G. HYDER, of Plainwell, county of Allegan, and State of Michigan, have invented a new and useful 1mproren'ient in Stock-Gallows, which improvement is fully set forth in the following specification, reference being had to the accompanying drawings.
The object of myinvention is to handle stock more easily and neatly than by any other stockgallows now known or used.
Iuse a siX-spoked wheel orderrick supported on the column A; also the upper derrick B,- with its rope and pulley-blocks O 0 attached to the gambrel-hook d, which is used by' being hitched to a gambrel-stick, e, as shownin Fig. l ot'the accompanying drawings. After the stock is dressed it is raised by means of the tackle high enough to be swung on one of the arms S of the six-spoked wheel or derrick, so
that the gambrel-stick 6 will 'rest on the arm or spoke S between the gambrel-hooks d, so
that the hooks d maybe loosened and taken.
out when the ropeis loosened, so as to lower it for another. The Lower derrick is turned or the upper one, B, on their centers, at the option of the workman, in either direction, so that when the next one is raised itmay be swung so as to meet the next empty arm-spoke S, and so on until all are full when two or more can be placed on each arm or spoke S.
Resting upon the column A is a flanged hub,
f, which serves as a protection to the wood,
and forms a bearing to bottom of upper derrick B, and a bearingt'or the six-spoked wheel or derrick, so that when it is loaded it will turn very easy, and is kept to its place by lugs k,
which hang over the square sides of column A. The lower partof the upper derrick B rests on the top of the flanged hub f, and also has a hearing to protect the bottom of the wooden spire g. Upon the top of the spire g and described.
