Patented Oct. 1, 1912.
Application filed March 25', 1912. Serial No. 685,985.
To all whom it may concern:
I do declare the following to be a full, clear, 1
same.
This invention relates to the class of hoisting, and more especially to capstans;
and windlasses; and the object of the same is to produce a very'compact device of this character intended primarily for moving mining machinery and about the shop or in the mine, carrying its and provided with means for instantly throwing the drum out of gear with the motor so that the action of the windlass may be checked without cutting off the power. This and other objects are accomplished by the construction hereinafter more fully described and claimed, and as shown in the drawings wherein- Figure 1. is a side elevation, and Fig. 2 a central vertical sectional view of this device with the gear wheels engaged with each other. Fig. 8 is a cross section on the line 3*?) of Fig. 1, with the gear wheels out of engagement with each other. cross section on the line H of Fig. 1. v
In the drawings the letter M designates broadly a motor (here shown as of the elec;
tric type) whose power shaft carries a pin ion P, the whole being disposed within a frame F forming no part of the present invention excepting that it serves as a support for the mechanism to be described below. Secured upon said frame is the base 1 of this improved Windlass or capstan, the same having twin lugs 8 rising from its rear end and perforated as at 3, and twin lugs 4t rising from its front end and one of them having an eye 5 for a purpose to, appear.
The numeral 6 designates a drum which is mounted fast on a shaft 7 whose rear end is journaled in a block 8 which is pivoted in the apertures 3 of the twin lugs 2. In Fig. 4 I have shown set screws 9 passing inward through said apertures 3 and on whose tips the block 8 is held so that it may rock slightly between the lugs 2, and the purpose of these set screws is to permit the block to other heavy objects 1 Fig. 4 is a p 7 p be removed when desired. Forward of the Be it known that I, Lian BAYER, a citizen of the United States, residing at Willisville, in the county of Perry and State of Illinois, 5 have invented certain new and useful Im provenients in Capstans or Windlasses; and
in engagement with the pin- A spec1al. feature of this invention lies in forming the bearing 10 within a block 26 which is of a size to fit closely between the adjacent faces of the spaced lugs so as to resist lateral movement of the block when the machine is doing work. The upper face of "the block is preferably beveled oif as shown in dotted lines at 27 inFig. 3, so that the arm 11 may pass across the same as therein indicated; and rising from the blOClEr'iS a hook 28 which engages over the upper side of the arm as best seen in Fig. 2. The block is depressed by pressure of the arm 11 upon'it, and it is raised by engagement of the arm 11 beneath the hook 28 in a manner which will be clear.
If desired, I may form ratchet teeth 29 on the rear end of the drum 6 and pivot a pawl 30 at 31 in the block 8 so that after the drum has been employed to put tension on a rope the pawl may be turned to engage the teeth and hold the parts stationary. If this detail be employed I prefer to pivot the pawl to the block 8 which has only a rocking motion on its trunnions or set screws 9. The length of the crank 18 is by preference exactly such that when turned downward the teeth of the gear 25 and pinion P are fully in mesh, and when turned upward these teeth are thrown out of mesh but the block 26 is not raised out of its position between the two lugs 4.
'a Windlass, the rope 7 passed around an idle The parts of this machine are of the desired sizes, shapes, proportions and materials and changes in details may be made without departing from the principle of my invention.
It will not be necessary to illustrate and describe the uses to which a machine of this character may be put. When employed as from the drum is usually led upward over a sheave or pulley and then downward to some weight which is to be raised, but when employed as a capstan the rope from the windlass is led to a distance and either attached direct to some article to be drawn toward the machine or pulley or block and led thence to the article which is to be moved. Particularly I employ this machine for moving heavy pieces of machinery from one point to another in the shop, or per haps for drawing them into a mine if they are mining machines, and drawing them out of the same when their usefulness has reached its limit.
What is claimed as new is 1. In a windlass, the combination with a motor having a pinion on its shaft, and the motor frame; of a base mounted on the latter and having spaced lugs rising from its front and rear ends, a block pivoted between the rearmost lugs and having a bearing, a block slidably mounted between the forward lugs and also having a bearing, means for raising and lowering this block drum, a shaft fast through the drum and journaled in both bearings, and a driven gear on its front end adapted to be engaged with said driving pinion.
2. In a Windlass, the combination with a motor having a pinion on its shaft, and the motor frame; of a base mounted on the latter and having spaced lugs rising from its at will, a
front and rear ends, a block pivoted between the rearmost lugs and having a bearing, a block slidably mounted between the forward lugs and also having a bearing, a hook rising from this block, an arm passing over the block and under its hook, a link pivotally connecting one end of the arm with one of said forward lugs, a crank shaft journaled on the base and having a handle at its rear end, a link connecting its crank with the other end of said arm, a drum, a' shaft fast through the drum and journaled in both bearings, and a driven gear on its front end adapted to be engaged with said driving pinion.
3. In a Windlass, the combination with a base having spaced lugs rising from its front and rear ends, and a power-driven shaft having a pinion forward of and below the forward pair of lugs; of a block slidably mounted between said forward lugs and having a bearing, means for adjusting this block vertically, a second block loosely mounted between the rearmost pair of lugs and having a bearing, set screws passing through these lugs and with their tips loosely engaging the sides of this block, a pawl pivoted to the latter, a shaft journaled in the bearings in both blocks, a gear on its front end adapted to be thrown into mesh with said pinion, a drum fast on the shaft between the blocks. and ratchet teeth on the rear end of the drum adapted to be engaged by said pawl.
In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
