SPECIFICATION forming part of Letters Patent NCL. 672,222, dated April 16, 1901.

Application led .l'uly 5, 1900- To all whom it may concern:

Be it known that I, HENRY H. BOGGS, a citizen of the United States, and a resident of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Winches, of which the following, taken in connection with the accompanying drawings, is a full, clear, and eX- act description.

This invention relates to mechanisms of various kinds in which a worm is employed for different purposes, and it has special reference to a winch in which a worm is combined with the usual and well-known gear to impart rotary motion to the winding-drum.

One of the objects of the invention is to arrange the worm in such relation to the other spur-gear as to produce a great amount of power in the winding-drum with the requirement of a small amount of labor on the part of the person operating the worm.

Another object is to provide means to lock the worm against rotation in one direction to prevent reverse motion of the winding-drum, and another object of the invention is also to provide the winch-frame with means for attaching the same to its support.

Furthermore, the object is to produce a winch which shall be simple, strong, and durable in construction and at the same time efficient in its operation and also inexpensive in its manufacture.

The invention consists, first and essentially, in the combination, with a supporting-frame, of a Winding-drum and a spur-gear journaled on said frame and suitably connected, a worm imparting motion to the aforesaid spur-gear and formed with a plurality of abutments or shoulders, means for rotating said worm, and means automatically engaging said abutments for the purpose of preventing a reverse motion of the drum.

Furthermore, the invention consists in the novel details of construction and arrangement of the component parts, as hereinafter fully described, and specifically set forth in the claims.

In the accompanying drawings, Figure lis a side view of a winch embodying my improvements. Fig. 2 is a rear end View. Fig. 3 is a plan view of the same. Fig. 4 is an enlarged detail view of the dog which engages Serial No. 22,46 7. (No model.)

the worm and the guide for the same and showing the means for holding said dog out of engagement with said worm. Fig. 5 is a vertical section on line X X in Fig. l. Fig. 6 is an enlarged end view of the worm, showing the abutments or shoulders. Fig. 7 is a front end view of the winch-frame, showing the manner of attaching one of the supporting-legs. Fig. 8 is a transverse section on line Y Y in Fig. 7. Fig. 9 is a transverse section on line Z Z, Fig. 3.

Referring to the drawings, A represents the Winch-frame, which is constructed of metal and is substantially of rectangular shape, although the same may be of any other desired form or design. Said frame is formed at one end with two pairs of rigid jaws a a for the reception of a horizontal supporting-bar a'. The face of each lower jaw is inclined, and between said lower jaws and the aforesaid bar are placed wedges b b, whereby the frame is firmly attached to the bar, and to said bar is secured a pair of supporting legs b b. The bar a is provided on its top with two thimbles b3 h3, which are firmly secured in recesses c3 .c3 by means of screws c4 c4. Said thimbles are adapted to enter holes cl3 d3, formed in the respective upper jaws a a, and serve as guides in attaching the winch-frame to the bar. The opposite end of the frame A is formed at its center with a vertical socket c, in which is secured another supporting-leg c.

It will be seen that the winch-frame can readily be attached to a wagon, in which case the bar a and supporting-leg c are dispensed with, as the aforesaid jaws a, a receive the end of the platform of the wagon and the wedges b h are placed between the platform and lower jaws in the manner hereinbefore described, and the draft of the rope or cable on the `winding-drum B, hereinafter referred to, will effectually hold the frame in its position.

Extending across the top of the frame A is a shaft d, mounted in suitable journal-boxes c e, and to said shaft are secured the windingdrum B and a spur-gear O, and on said drum is wound the usual rope or cable ol.

To the under side of the frame A is secured a horizontal plate e', which is made detachable by means of bolts f f. Said plate e is formed with a pair of journal-boxes f' f2, which are axially in line, and in said boxes is IOO mounted a shaft g, which is under the aforesaid gear C and is disposed with its axis at an angle to the axis of the shaft d.,

To the shaft gis secured the worm D, which is located between the journal-boxesf f2 and is thereby sustained against longitudinal movement.. Said worm meshes with the gear C to impart rotary motion to the aforesaid drum B, and to one end of said shaft g is applied a hand-crank g for rotating said worm. The threads of said worm are terminated abruptly, thus forming a plurality of abutments or shoulders h 7L, as shown in Figs. l and 6.

The aforesaid journal-box f2 is formed on its outer side with a longitudinal guide h', which is parallel to the axis of the worm, and in saidguide slides a dog t, which is preferably of the form of a bolt and has its engaging end facing the walls of the threads of said worm. In the rear end of the guide h is secured a bushing t', which is formed with a head a2, bearing against the end of the guide and is provided with a longitudinal hole b2. Extending from the inner end of the dog t' and rigidly secured thereto is a longitudinal rod c2, which passes through the guide and through the aforesaid hole b2 in the bushing. Between the dog and bushing is located a coil-spring d2, which serves to force the dog outward, whereby its outer end is held against the threads of the worm and is thus made to engage the abutm ents formed on said th reads to lock the worm against a reverse movement, and thereby prevent-the unwnding of the drum B. Through a transverse hole e3 in the i rod c2 passes a pin e2, which is seated .in a

transverse notch g2, formed in the head a2 of the bushing when the dog i is in position to engage the abutments on the threads of the worm. The pin cgis bent to form a link and has its ends secured in recesses f3 f3, formed diametrically opposite in the rod c2, whereby the pin is prevented from dropping out of the hole e3. Said link forms.a thumb-piece by which to operate the dog by hand, whereby the same can be retracted sufficiently to allow the abutments h h to clearit. By thus retracting the dog the pin is moved out of the notch g2, and the rod c2 can then be turned and the pin made to bear on the face of the head a2, whereby the dog is locked in said position.

What I claim is- 1. The combination with a suitable frame,
