- UNITED JONATHAN F. BARRETT, OE NORTH GRANVILLE, NEW YORK.

HORSE-POWER.

Specification ofl Letters Patent No. 5,348, dated October 30, 1847'.`

To all whom t may concern.' l

Be it known that I,JONATHAN F. ,BAR- RETT, of North Granville, in the county of; Washington and State of New York, have invented a new and-Improved Machine for Horse Powers on Machines; and I do hereby declare the following to be a full, clear, and exact description of the same, reference be-v ing had t0 the annexed drawings,`making a part of this specification, in which- AFigure I is a' perspective viewy of the Ina-g chine, showing construction.` Fig. II is aE perspective view of the under or lower side; of the pawl. Fig. III is a plan of the pawl,

showing the parts on its underside. ,f

The nature of my invention consists inthe provision of ropes toact upon a set of pul` leys ycombined as described, with the sweepv and other parts, for operation, and bywhich I 'effect the important objects of `saving a material 4part of the ,friction required inl other horse power machines. Y

To enable those skilled to make and use my invention, I-will describe its construction and operation, as follows.

I provide a sweep, (a), as seen in all-thefigures inthe drawings; and this sweephas several attachments upon its under or lower side, when it isplaced for work in the machine; these attachments will be seen in Figs. II and III, and may be known as (b and b) which act upon the several parts for engaging and disengaging the cords, each alternately performing its part as here' after more fully set forth, and two sweep guides (c, 0') each of which are alike and perform alike to guide properly the sweep in its revolution by catching upon the `seg-V ment curve. The sweep also has uponit, the pulleys (d and d), each of which are similar and perform alike to take up the cords at the. proper times, each alternately.y The sweep, (a), is a piece, hung by a pivot at the center, and is of the common construction of sweeps; and this is to be used to hitch. the horse or cattle for giving motion'to thei machine. The sweep is placed over a suitable set of timber work, which for conven' ience may be connected at thecenter and ra-1 diate outward the required distance; these radial timbers may be lmown as (w), and

upon these is planted in suitable manner,-

the segment curve, or semicircular ring; and outside of this rmg or segment curve, are

placed friction pulleys, so as to receive the f vcords as they are passing aroundinforder to keep the cords properly tight, until theyfare relieved by beinglthrown off at (),fthese pulleys are known as (el e2 e? e4) thesemicircular segment is 'known as (f) and. upon this the sweep rests, and the ihooks (0,50) catch to support and keep steady the sweep while the same end of it is in contact with the cord, or working'end. The front or straightv side of this timber` work, (g),

yserves the additional purpose of connectingv by attachments, th'eQparts which in connection'with the Vpulleys (d and d) engage 'and'.disengage thefropes (prand g). A disengaging leverk (z' to i) isset to act-,upona` fulcrum placed upon (g), `and hasuponone of its ends a weight or counter balancey (2), and at the opposite end, or (i), -is formed into a cam lof a proper shape to disengage the ropes from either of the pulleys (cl: or

d) yon the arrivalfat this'pointrthe saine j y g being operated by the sweep as'it acts upon the cam ('z'), which by its shape,`slips over the belt on the end ofthe pulley nearest'to l- 'belty and press it down'until vit is thrown oif s Y the pulley andv is disengagedtherefrom; by f Y. y c

its point, so as to takethe top of the ropeor such throwing/off. Thepressing downo'f (i) is performed bythesweep and thev cam` (i), isfa'ga-m returned toits proper position 1:85

by :the counterbalance (i), so that it may throw off in like manner the belt at the re-V turn .ofthe end of the sweep with a cord upon its pulley, which'co'rd may be either thrown off or disengaged,

( or g) as they alternately come here to bef" yThe engaging apparatus may be asfol-l"y lows: The lever puts the rope in 'a proper position to be engaged by the'proper i195 pulley and is drawn back by the cam `(b)' during the winding upvof the rope (p) so as' f to be ready for the neXt operation; (7c) has its fulcrum lat (w), and is, atits opposite y .end attached to the connecting rod Z), and this tothe middle of a vibrating' lever -which has its fulcrumat'its lower end and at its upper end is connect-ed withl and car-k y ries the cord to' be engaged or operated,y The p c lever (7c) is a vibrator and is actuated by the two cams (b vand b) (atlixedto the sweep) alternately; v(7)) throwing the lever (m) with the rope (q) forward in position for it to be engaged by the pulley (cl) and (b) gives it the reverse motion for the purpose of laying the rope `g snug set to the stud `the shaft.

the other end of the sweep is about over the pulley (e4). Thus, it will-be understood that by the sweep and its cams (Z) and b) the lever (lo) is so placed that each cord will' be sure to be caught by the pulleys (ai, and cl) in regular succession. Of the ropes,

which may be of any material which will yield to the requisiteextent; that is, of ropes, belts, chains, etc., two are required, andare (p and g) in the drawings. The first,` or (p)V is'made fast to a permanent staple (r) and passes between the guide stud (s) and the lower groove of l the pulley v(e) and then passes to one of the main drums the second or (g) has one endattached to the vibrating lever (m), Iand passes between the same stud (s) and the upper groove of the pulley (6') onwardto -the othermain drum (o). The drums orpulleys (t and 11) are material parts ofthe-apparatus, and are both placedupon the shaft, vas well as isthe fly-wheel; each drum running free upon the shaft (o), and vin contrary direction Vto the shaft, while the respect-ive rope on each ,is

drawn o by its engaging pulley, but travels with the shaft whenthejcord is wound up on each respectively, by the action of an en- `gaging pawl, each of the ropes in turn; andv each of the drums having a circular motion of a reciprocating character; that is, afletting off and taking on ofrope alternately, one and the other. Each of these main drums has a beveled wheel on theirinner nds and these wheels are' connected by' a third or an independent` beveled wheel,jy

which connects the .two and causes each toV be sure and take their respective' andLoppo-V site directions precisely as the cord engaged by the pulley on the sweepdirects. Both `these drums (t and c) actalternately upon .loose upon it, the shaft (o), until the drum reverses motion, when the pawl acts to drive Other equivalents may be` sub`y stituted to drive instead of the pawls,'and produce a like result. 4Thus one ldrum isi always driving and one loose on the shaft,"y except `at the instantof changing motion;

and each alternately "becomes a ydriver in place of the other, as the cords run out and return glvlng such motions to these drums;

that is the alternate backward and forward motions.

While I intend to-use this machine with horses for power to drive it, also cattle may be used or even other powers may be applied in combination to produce a good result.

The operation'may be understood as follows: One, or any other number of horses or other power may be applied or attached to the Vsweep in any suitablev way; and,

. thereby the sweep is put in revolution and catches the cords successively upon the pulleys l(0l or cl) and brings them one at a time, to the disengaging cam (i), where they l are successively thrown off and are allowed tobe drawn back and wound `up successively upontheir respective `drums. About the time of disengaging one of these ropes (p or g) theother is engaged by the pulley on the other end of the sweep, and thus by one rope the other is drawn ,back through the action wound upon its own drum. These motions are alternately repeated as often as the lengthof either cord is run out by one of the pulleys on the sweep, the rope being immediately though indirectly taken up by the other. The main drums in this way receive ltheir respective motlons, and the drum on` whichjthe rope is being wound up conveys the motion to the shaft upon which the fly or bandwheel is hung giving toits the conl.tinuous straight forward circular motion.

The pawls or spring dogs, before referred to areused to give `the motion to the onward drum and-'freedom to the other in its reversed motion, but as yother well known mechanical equivalentsmay Abe used to allow the same motion of the two drums Ido not claim theselpawls and ratchets for the purpose of reversing the .motion of the drums,

vwith the belts and drums, inclusive of their several operations as herein fully-set forth and described, for the purpose of a horse or other power, whether the same be effected `by these precise means, or by mechanical equivalents producing substantially the same 'rey sult.
