WINDLASS.

Specification of Letters Patent. Patented Sept. 14:, 1909.

Application filed July 20, 1908. Serial No. 444,495.

To all whom it may concern:

Be it known that I, JOHN S. ORAM, a citizen of the United States of America, residing at Cleveland, in the county of Ouyahoga and State of Ohio, have invented certain new and useful Improvements in WVindlasses; and I hereby 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 the same.

This invention relates to improvements in windlasses more especially designed for the bending into the proper shape to form a barrel of a set of staves which are widest centrally between and gradually reduced in width toward their ends and assembled on end and placed tightly together within a hoop placed upon the floor.

The primary object of this invention is to provide a Windlass of the character indicated whereby the staves are quickly and properly bent into the shape required to form the barrel.

Another object is to provide a Windlass comprising a winding drum and a guidesheave which is arranged laterally of the drum and engaged by a chain or cable which is operatively attached at one end to the drum and extends to and over the sheave and employed in controlling the size of the loop formed by a rope or flexible band which is arranged between the sheave and the drum and has one end-portion thereof attached to the other end of the said chain or cable, said loop-forming member having its ,pther endportion crossing the first-mentioned end-portion of the loop-forming member and attached to another chain or cable which is operatively connected with the drum and employed in controlling the size of the aforesaid loop and both chains or cables being arranged to be simultaneously wound on or paid out by the drum according as the drum is rotated in the one or the other direction and operatively connected with means acting to unwind the chains or cables from the drum so that the drum, as soon as it is ren-- reliable means acting to actuate and thereby a draw both ends of the loop-forming member toward each other to loosen the loop relative to the barrel and thereby to permit of the removal of the loop-forming member from the upper end of the barrel after a hoop has been placed around the set of staves at the said end of the barrel.

With these objects in view, and to the end of realizing other advantages hereinafter appearing, this invention consists of certain features of construction, and combinations of parts, hereinafter described, pointed out in the claims, and illustrated in the accompanying drawings.

In the said drawings, Figure 1 is a side vention. Fig. 2 is a top plan of the windlass, and portions are broken away and in section in this figure. Fig. 3 is a vertical section on line 33, Fig. 1, looking in the of the barrel to hold the staves in their bent form.

My improved Windlass comprises a horizontally arranged rectangular or oblong bedplate A which is mounted on and suitably secured to legs a under the ends of the bedplate and resting on the floor m as shown in Figs. 1 and 4:. A winding drum D is arranged horizontally over and transversely of one end-portion of the bed-plate A and operatively mounted on a correspondingly arranged shaft (Z. The shaft d has bearing in two boxes 6 and 6 arranged at opposite ends respectively of the drum and supported from the bed-plate A.

On the shaft (Z between one of the boxes 6 and the adjacent extremity of the shaft is loosely mounted a gear G which is slidable endwise of the shaft and meshes -with a pinion]? operatively mounted on a suitably supported shaft p which is arranged horizontally below and parallel with the shaft d. The shaft 79 is operatively provided at its rear end with a driving pulley p to Which power is applied by a suitably driven belt elevation of a Windlass embodying my 111- A friction-clutch for controlling operative connection between the gear G and the shaft (Z is provided (see Fig. 2). One member 6 of this clutch is formed on the gear at the inner end of the gear, and the other member 7 of the clutch is operatively mounted on'the shaft next the outer end of the adjacent box 6. Obviously therefore a shifting of the gear G inwardly toward the winding drum establishes operative connection between the companion members 6 and 7 of the clutch and thereby operatively connects the said gear with the drum and consequently the latter with the shaft 79, and it will be observed therefore that the said gear, to inter rupt operative connection between the drum and the shaft 2 is shifted outwardly.

The gear G is provided at its outer end with a hub g which has an annular peripheral groove 9 engaged by a lever I for shifting the gear, which lever is suitably supported from the adjacent leg CL, being preferably fulcrumed at its lower end, as at I, horizontally and at a right angle to the shafts (Z and p, to a bracket a rigid with the said leg, as shown in Figs. 1 and a. Of course the pinion P is long enough to be in mesh with the gear G in either position of the gear.

As already indicated, the drum D is arranged over one end-portion of the bed-plate A. A guide-sheave J is placed with its axis vertically over the other end-portion of the said bed-plate. The sheave J is supported from the bed-plate in any approved manner.

A rope or flexible band or member K is arranged between the sheave J and the drum D and is preferably in the form of a loop and has its end-portions crossing each other and projecting toward the drum D and sheave J respectively. That end of the loop-forming lneinber K which projects toward the sheave J is operatively attached to one end of a chain or cable L which leads from the loop-forming member to and over the sheave and thence to and is operatively connected with the drum, and the other end of the loop-forming member is operatively attached to a chain or cable Q which leads from the loop-forming member to and is operatively connected 'with the drum.

The loop-forming member K is arranged to encircle a set of staves s' which are placed in an upright position on the floor on within a hoop 7b which rests on the floor and are tightly fitted together at theirside edges within the said hoop to form one end of the barrel to be formed. The staves are widest centrally between and gradually reduced in.

rounding of the'set of staves at the upper end of the staves by the loop-forming member K. Y i

The gear G is rotated in the direction indicated by the arrow placed thereon in Figs. 1 and 4, and, upon shifting the said gear inwardly to establish operative connection between the companion members 6 and 7 of the clutch, the drum D is rotated in the said direction and thereby winds up the connected chains or cables L and Q, and the winding up of the said chains or cables-actuates opposite ends'of the loop-forming member K toward the sheave J and drum D respectively and thereby reduces the size 'lof the loop formed by the said loop-forming member and bends the staves into the shape required to form the barrel, and when the staves have rangement of the parts is such that the said pawl and ratchet-wheel cooperate in preventing a return movement of'the driun "D during the application of the hoop h to the barrel upon arresting the rotation of the drum in the direction required to wind up the engaging chains or cables, but, ofcourse, the said pawl is disengaged from the ratchetwheel preparatory to the loosening of the loop-forming member K relative to the barrel, and obviously the said loop-forming member immediately upon the application of the hoop 72/ to the barrel is loosened relative to the barrel to permit its removal upwardly from the upper end of the barrel upon rendering the clutch inoperative and thereby permitting the rotation of the drum in the. direction required to'pay out the arranged longitudinally of the bed-plate.

Two sheaves 10 and 12 which are placed with their axes horizontally and parallelly are arranged within opposite end-portions respectively of the slot 8 and suitably 'sup ported from the bed-plate. V

A stationary bar R is arranged below the bed-plate A and has. its centralvpor'tion 13 arranged horizontally and longitudinally of the slot 8 and below the sheaves 10 and 12.

The bar R has opposite end-portions 1 thereof diverging downwardly from the cenplate. Each end-portion 14 of the bar It forms a guide for a weight w which has a vertical slot 15 through which the said guide extends and is provided with two suitably supported horizontally arranged parallel rollers 16 arranged transversely of the said slot and spaced longitudinally of the guide.

Two chains or cables 17 and 18 lead between and over the sheaves 10 and 12 respectively and are attached to the weights w. The chain 17 leads fro-m the connected weight to and over the sheave 10 and thence to the chain or cable L with which it is operatively connected preferably substantially at the point of connection between the said chain or cable L and the loop-forming member K. The chain or cable 18 leads from the connected weight to and over the sheave 12 and thence toward the chain or cable Q, with which it is operatively connected preferably substantially at the point of the connection between the said chain or cable Q and the loop-forming member K.

It will be observed that the weights to act to pull the adjacent ends of the chains or cables L and Q toward each other and consequently act to rotate the drum in the direction required to pay out the said chains or cables and to loosen the loop-forming member relative to the upper end of the barrel formed by the said loop-forming member. Obviously therefore when the upper end of the barrel has been formed by the winding of the chains or cables L and Q upon the drum and a hoop it? has been placed around the upper end of the barrel, as shown in Fig. 1, the operative connection between the drum and the gear G is interrupted and the pawl t disengaged from the ratchet-wheel T to permit the said drum to rotate in the direction required to pay out the connected chains or cables, and obviously the drum when it has thus been rendered free to pay out the connected chains or cables will be rotated by the action of the weights w in the direction required to pay out the connected chains or cables and thereby loosen the loop-forming member relative to the barrel to the extent required to permit the said loop-forming member to be removed upwardly from the barrel. I would also remark that during the bending of the upper portions of the staves inwardly by the operation of the loop forming member K the barrel being formed may, in any approved manner, be held or prevented from tipping.
