Description

W, am j o/a. ,W m Uf/.Z dwf iw h. w mw d AM. PHOT-LITH'U. C0. NM (OSBURN E'S PROCESS) city, county, and Sltate of New York, have known by the following names, viz, capstan,
` vention, I will proceed to describe itscon-` scription, at A., Figure l, is shown in section y segments of four cog-wheels E E E E, as
Vmeans of which the winding motion of the shall denominate tumblers; upon those four PETER ROBERTS, or NEW YORK, N. Y.
CAPSTAN.
Specification of Letters Patent No.
To all whom it may concer-n;
Be it known that I, PETER ROBERTS, of the invented a new and Improved Method `or Arrangementof Constructing the Machine known by the name of Capstan. or Heaver, as commonly used on shipboard; and I do hereby `declare that the `following is a full and exact descrip-tion thereof, reference being had to the accompanying` drawings and to the letters of reference marked thereon.
The nature of my invention, consists of a new combination of mechanicall elements, arranged within the base of a machine,
windlass or heaver, as commonlyused on ship board; the object of which arrangement, is the continuous winding motion of that part called the head, (upon which the rope or chain is wound) while the levers, or heavers, are caused to move alternately backward and forward.
In order therefore to enable others skilled in the art to make and use my instruction `and operation.
In the drawings accompanying this dethe main head, and at B, isshown in section, the box or base of the capstan, with the upright shaft C, (of wrought iron) and firmly secured to the base B. Upon this upright shaft is supported the main head A, `and upon which shaft the main head, can revolve freely; the head, being secured from a lifting action (caused by the pawls M M,) by means of the circular plate marked I, which plate is composed of two semi-circular parts as shown at I, for the purpose of putting it on to the head of the shaft C, this plate being secured to the arms of the main head, by means of four screw bolts, (two in leither half) two of which are shown in section, near I. I/Vit-hin the base or box B. is contained the improved parts, by
main head is made continuous.
At S, S, in the sect-ion Fig. l, is shown an end view of two shafts; (the same shafts are shown in part at S, S, Fig, l, plan view.) Upon those two shafts are placed shown in plan and section Fig. 3, which I tumblers rests the piece marked D, and which 8,746, dated February 17, 1852.
I shall denominate the slide. This slide is shown at D D, in plan. and section Fig. 3, and being composed of a plate of cast` iron, a-nd having an opening` in its center and through which the upright shaft C, shown in Fig. l, passes; the opening in the center being suiiciently large to allow the slide D, to move alternately backward: and forward-motion being imparted to this slide by a vibrating motion of the `fourtumblers upon which the slide rests; this slide having cogs, upon its upper and lowersurfaces, arranged inright .lines as shown in the plan Fig. 3, one row of which is represented by dotted lines, indicating, that they are located on the under surface of the slide, those cogs being cast in one piece with the slide,
there being four rows of cogs, upon the same shown at E, E, and H, in Fig. 3, the other two rows of cogs, upon the slide, are turned inward and gear into the two wheels marked P, and Q, as shown in section Fig. l, and
so by plan in Figzt, together with a detached j portion ofthe slide containing the cogs, .1
`and where the wheel P, is represented as above the slide D, and having its cogs upon its lower surface, while the wheel Q, is represented as having its cogs upon its upper surface. In the plan Fig. 8, is shown upon the slide D, the relative position of the two wheels P,and Q, by a dotted line, as also the cogs upon the slide D, and in section thus I At Gr-Gr, in Fig. 3, is shown by plan and section a ratchet wheel of peculiar const-ruction; this. wheel, having an elongated hub or tube, cast with the wheel in one piece; this ratchet wheel, being adjusted upon the upright shaft C, as shown at G, in section Fig. 1, in its working position, and being at liberty to revolve upon the shaft quite freely; the hub of this wheel G, serves as a shaft for the two wheels P, and Q, as shown in section Fig. 1, and upon which they severally revolve or vibrate, a portion of a revolution at each motion o-f the levers. Detached portions, of the upper surfaces of the two wheels G, and P, are shown in. their relative posit-ions in'V plan view Fig. l, as
having the upperworks removed.
At N N, in section Fig. 1, are shown two pawls, and represented as beingattached to the wheel Q and fallen into the teeth of the l ratchet wheel G, and in their working position. At LNI-M, in section Fig. l, are likewise shown two pawls represented., as being attached to the lower arms of the main head A, and fallen into the teeth of the ratchet wheel P, and also in their working order. The two shafts S, S, are shown in part near B, in the plan Fig. l, and in their proper places and having one of the tumblers E, adjusted upon each in its proper place the upper works being removed.
At H H, in Fig. 3, is shown a side view of the slide D, and at H, resting upon the two tumblers E E, in their working position. The sockets F F, upon the shaft S, in section Fig. 3, (one of which is shown at F, with the lever or heaver in its place and broken off) likewise, two of the sockets and levers being shown in elevation at F, in Fig. 2, there being four levers in all.
The cover of the base marked O, the ratchet L, upon its upper surface (and pawls for the same) the main head A, and its cover J, are severally sockets, covers, head, &c., of the ordinary kind now in use, and therefore need no particular description.
From the previous description, it will be understood that the whole apparatus is operated by a vibrating motion of the levers F F, shown in elevation Fig. 2, there being four, two on either side, now therefore it will be seen, that when the levers are in the position indicated in the elevation Fig. 2, that the slide D, has been moved in one direction to the extremity that it is intended to be moved, and that in its motion thus, it
Vhas carried or turned the wheel P, in one direction, and the wheel Q, in the contrary direction, and that in turning the wheel Q, the ratchet wheel G, (by the act-ion of the pawls N N,) must of necessity be turned in the same direction as Q., and the main head A, being made fast upon the up-v per end of the hub of the ratchet wheel G, it is turned in the same direction; during which operation, the two pawls marked M M, and attached to the arms of the main head, are carried with it while the wheel marked P, is turned in the contrary direction. Upon reversing the levers it will be seen that the slide D, will be moved in a contrary direction, and that in its course it turns the wheel P, in a contrary direction from what it was turned by the first motion of the levers, and that the wheel P, (by the action of the pawls M M,) turns the main head, in the same direction as it was turned by the first motion of the levers, and that in so turning, it of necessity turns the wheel Gr, along with it while the wheel Q, is turned in the contrary direction from the wheel G,
and the two pawls N N, are carried by the wheel Q, to a new place in the teeth of the wheel G and are therefore ready to perform a second operation similar to the first. The pawls outside upon the main head acting momentarily to sustain the main head during the momentary stoppage of the levers while being changed from one direction to the other.
The combined parts as set fort-h in the previous description, when operated as herein shown, serves to keep the winding motion of the main head of the capstan continuous.
What I claim as my invention, and desire to secure by Letters Patent, is-
The combination of the following mechanical elements, viz, the vibrating tumblers acted upon by handspikes; the slide D, with its racks; the cog wheels P, and Q, the former formed also with ratchet teeth; the ratchet wheel G, and its hollow shaft; the pawls M, and N, the whole arranged within the base B, and with respect to each other, and acting substantially as described.
