IMPROVEMENT IN FASTENINGS OF HAY-RAKES.

l Specification forming part of Letters I atcnt No. 7,63@ dated September Il, 1851i.

To all whom it mag/,concerm Be it known that I, ORANGE W. IIOGLE, of the town of Son'ierset, in the county of Niagara and State of' New York, have invented newl and usel'ul Improvements inl the' construction ot' Revolving Horse Hay-Rakes, which are described as follows, reference heilig had to the annexed drawings-of the same, making part of this speciticatiou.'

My improvements relate 'particularlyv to the manner of constructing the' wooden cyma-reversa teeth oi' the rake and the manner ot holding them during the operation of' raking', and the manner of revolving them while dis-` charging thehay into a windrow, the tot-mation and arrangetnentof' said teeth and other parts of'the machine being sueltas to render the raltethelightest, cheapest, and most symmet rical rake of allthe revolving horse hay-rakes innse.

Figure 1 is a birds-eye view of thc rake.

`Fig. 2 is a side elevation ofthe same as in operation. Fig. 3 is a section of one of the teeth and a portion of, the revolving shalt. -liig. 4

Ais a. side view of one of' the teeth.

o dried lcut it into two parts,each embracing a segment of a circle ofninety degrees. Each of these segments is then tapered neatly and rounded at the point, and notched at the larger end tor ship-lapping. This will form two teeth, d. l tlien take these two teeth and insertthem into an oblong opening in the shaft a and ship- Alap their two large ends and secure them by -a wedge, e, as seen itt Fig. 3, the' two teeth d lthus placed and secured formingacyma-reversa figure, as represented in the drawings at Figs. 2 and 4. The teeth of the rake being all formed "and secured in the same simple manner, when-- evel` it becomes necessary to renew a tooth the farmer need notsend' "his machine to a shop, as hecanejaslilymake and insert a tooth himself. The manner ot' holding the teethin the required position during the operation ot' raking the hay and oi` revolvingtthem in order -to deposit the hay in windrows is equally simple.

Ou the shaft n, next the inner side or" one of the arms .c of thc guiding-frame, I secure a ratchet-wheel, j', and to the side ot' the arm next the wheel I attach a pawl, y, by a joint-pin,

h, which engages with the said ratehet-wheelf. Between the arms cc,l place a transverse sliding holding-bar, i, against which the convex sides or bow-surfaces ot' several of the teeth rest during the operation of raking, the ends of said bar t' being provided with tenons which slide in oblong grooves or tnortisesjin the arms. The ratchet-wheel and pawlare designed for holding` the teeth or lingerstirmly against the bar 'i by preventing the Shaft turning toward the bar. \Vhen it is required to turn th'e shaftI from the bar, or in the direction of the arrow No. l, in order to discharge the hay t'rom the teeth, the aforesaid sliding rest-bart` must be moved from the shaft toward the operator, so

as to allow the ends ot' the teeth resting against it to pass bythe same while the shaft revolves a portion of a circle. As soon as these te'eth have passed the im' it(th`e bar)' returns to its former position, to be in readiness to arrest the motion of the opposite set ot" teeth, which are held iu like manner by the combined action ot' this bar and the ratchet-wheel and pawl. The, bar is allowed to move toward the operator atv the required time to revolve and empty the.

iake by drawing a slide-holt, k, from behind the end of a stem, l, projecting back from the middle ot' the transverse sliding har t', and passing through an opening in afixedtransverse bar, m, lying parallel to the said sliding bar, the movement ot' the latter being caused by the pressure otf the convex surfaces ot` the teeth against it as they are revolved by thorwardmovement or draft ot the sha ft, and the resistance caused by the hay resting against the teeth. below the shaft, at the same time contractin g a helical spring, fn, coiled around the 'stem I, and having one. ot' its ends resting against thefsliding bar 'i o and the other end against the fixed bar in;

'lhc teeth having passed the bar, itis returned to its former position,by the action ofthe said helical spring n. t Upon the cross-bar m is arranged a reciprocating slide, lr, actuated by a coiled spring, p, and a liexible strap, o, attached to the slide It' e mers and to a hand-roller, pi The end of this slide ly the'comnion hand-rake, and will rake .nearly c'next the center of the machine is madeto cap over or cover` the upper end ot' the stem Z of the sliding bar z' by the action ofthe spring, thus' holding the rake firmly. A very slight movement, of therolier on its axis, eflectedvby the hand of the operator, draws back the slide and allowsthe transverse slide-bar to rise or recede from the teeth by the pressure of the convex or curved portions ofthe-teeth against said transverse sliding barffiermfi'ttiugthe ral`e teeth to revolve and discharge the hay behind the axle and to be 'adjusted for tbenext load..

Shoiild they. indi-ow not be high enough to bring 'the egnveiisurfaces of the teeth against the.

sto! arg i, bear down thetbar e' by bearing upon;

the hand-roller p, Afttbe saine time the pawl will sli'p Drenthe teeth ot' lthe ratchet-wheel" and lay hold ofone of them, and thus conn'e the rake-teeth against thebar. Th`en raise the roller and briner the ra ke-teetlto the-required position for raising the hay most ad vantgeously, which` selt'eeted in a /rnoinentby merely raising the roller. 'This hand-roller performsseveral important otiices besides that. of drawing back the slide and adjustingand securing the teeth. 1t serves 'to manage and guide the machine in any required direction; to raise or lower the 'points ofthe 'front teethv in order to avoid obstructions to throw the points ofthe teeth into bellows to rake ont the hay to litt the rake'liy holding back the shaft while the horse pulls forward, and by which to suspend the machine when not in use. The teeth being made of elastic hickory or ash'cr ther suitable wood, in the form ot aouarter of a circle, and inserted into the sha-tt in the manner described, permits thein to slide over the ground on the bow portions of theteeth, in the `manner of a sleigii-ruiiiier,'ai1d gather the hayl in trie most effectual and easy manner Without the usual injurious effect produced by causing the pointent' the teeth to scrape the ground, as in the use et' the wire teeth, and the Inachine being so very light and elastic that it can be made to rise from the ground and pass over linulls,k stonesr stumps, and other obstructions by the operation ot' simply holding baci; the machine by the roller while the horse is made to nieve forward, er by the raising; or lowering of the handle to any required pitch.

The teeth of this machine are :natie to seule nearly the same position et the teeth of or quite as clean,' and imposes no more labor upon the man or boy who guides it than sim/- ply to follow it with his hand upon the roller., from which it is not removed while at work. 1t- Will 'at once be discovered that this'revolving rake is 'drawnon the bow or curve'of the teeth, causing the shaft to be lifted from the ground atleast twelve inches, thus doing away' with the friction caused by drawing the shaft uponv the ground, and theiqnjurious effect arising-from itstearingup the young clover thrown up by the frosts of` the winter; and, likewise,

fitdoes n-otcover the hay with dust and dirt, as i is experienced by the use ofthe -rakes whosev teethvv have their points scraping over the ground, or whose beam drags upon the ground.

The cymareversateeth maybe matie iii-'one piece instead ot' two pieces; as before described 5 but'lfpreier making each tooth in two pieces and ship-lapping them in the inanner herein set, forth, as it can be replaced at less cost.

This rake will fold, and can be hung up in anyr convenient place in the barn. 'Y f Having; thus described the construction and operation otiny improved revolving horse hayrake, what Iclainn 'and desire to secure by Letters Patent, i s

1. The manner ofholiling the teeth d firmly in their required positions against the sliding bari' during the operation oi the machine by means oi the aforesaid combination of the ratehet-whcelf, pawl g, sliding bar i, and stem Z, helical spring n, iixed bar m, and slide k; at'- 'taehed thereto, with theparallel gnidingarnis c afnd revolving tinge-.reliatm arranged and operating in the inannerand for 'the purpose above set forth. Y

2. The combination of -the slide k, helical spring` q .strap o, and roller p, with the parallel arms c, and tixed bar m, for disengaging the., sliding: stop-bar i', from the ralieteeth d with ont moving the hand troni its usual position on the baii .ioiler p to allow the teeth to revolve to deposit the hay in wind'rows, as hereiny t'ully set t'crtln in testimony whereof l haveberennto signed my naine bei'nretwo subscribing witnesses.
