SPECIFICATION forming part of Letters Patent No. 315,765, dated April lli, 1885.

.Application led July 17, 1884. (No modali) The invention relates to machines wherein are employed two endless belts of combing or hackling pins, the liber being taken from the feeding-rolls by the lowerrnost portion of one belt, having its pins presented downward,and thence delivered to the uppermost portion of the second belt, having its pins presented upward, the two belts moving in opposite directions, so that their operative portions will move in t-he same direction, butat different velocities. Such a machine is shown and described in my Letters Patent No. 311,310, dated January 27, 1885, and the advantage of such reversed arrangement of the two belts of pins is that a closer nip on the ber is secured at the point of delivery from the first belt to the second than can be obtained when the two belts move in the same direction and have their upper portions operative. rEhe belts of pins which are used in these machines each comprise parallel pin bars or rods, two endless chains in the links of which the pin bars orrrods t loosely, so that they are capable of turning, and dogs whichl are secured fast to the ends of the pin bars or rods, and are fitted to guides or guidingrails in order to prevent the turning of the bars or rods, when desired, and to hold the pinsproperly presented for operation. The chain-wheels whereby the chains of the belts oi -pins are operated must be of considerable size in order to operate properly, and although by reversing the two belts of pins, as described in my aforesaid ap-` plication, I obtained a closer nip on the liber than had been before possible, I did not obtain as close a nip as I now deem desirablein order to obtain the best results. The reason of this was that in the former machine the travel of the rst belt of pins at its delivery end conformed to the circumference of the chain-wheels at that end.

The present invention consists in the coniwheels for the rst belt of pins arranged.

at the deliveryT end thereof', and guides or guiding-rails, whereby the down wardly-presented pins of the ,first belt are held in operative position, and which are extended forward of said wheels, whereby the direct travel of the first belt of pins is prolonged beyond its driving-wheels.

The invention also consists in the combination, with the foregoing, inclined forward and upward from the termination of the aforesaid guides or guiding rails, and acting upon the dogs of the pin-bars to hold the pins presented directly downward as they are withdrawn or raised out of the fiber, and preventthe pins from swinging forward and upward in leaving the ber.

The invention also consists in the combination, with the two belts of pins, arranged as described, the driving wheels, prolonged guides or guiding-rails, and inclined cams at the delivery end ofthe first belt, of stationary cams at the receiving end of the second belt, inclined correspondingly to those of the iirst belt and acting upon the dogs on the pin-bars of the second 'belt to hold the pins in vertical positions, so that they will rise straight into the iiber.

rIhe invention also consists in the combination, with a pair of feed-rolls and an endless belt of pins the lowermost portion of which is operative, with its pins presented downward, of a vertically-movable blade or plate arranged within said belt at its delivery end, and working upward and downward between the pin-bars to push down or throw off the liber from the pins, said blade or clearing-plate being preferably supported by pivoted arins having downwardly-proj ecting toes,which are acted upon by the pin-bars as they successively pass them in order to raise the blade or plate and allow it to drop.

In the accompanying drawings, Figure 1 is of stationary cams IOO a side elevation of a machine embodying my planes of Figs. 3 and 4, illustrating, on a larger scale, the guide or guiding-rail and stationary cams at the receiving and delivery ends of the rst belt of pins and the action of such guides and cams on the chain-dogs, the chains notA being shown. Fig. 7 is a transverse section of a guide rail and a portion of a chain and a dog fitting the guide-rail; and Fig. 8 is a side view, similar to Figs. 5 and 6, illustrating the stationary cams at the receiving end of the second belt of pins and their action on the chain-dogs, the chain being omitted.

Similar letters of reference designate corresponding parts in all the gures.

A A designate upper and lower feed-rolls, to which ber is fed from a chute or table, A2. The feed-rolls deliver ber to the rst belt of pins, B, the lowermost portion of which is operative, with its pins presented downward. From the rst belt the ber is delivered to a second belt of pins, C, the uppermost portion of which is operative, with its pins presented upward. From the second belt of pins, C, the ber passes to upper and lower drawingrolls, D D', at t-he delivery end ofthe machine; and thence the ber passes to a trumpetmouth or condenser, E, whereby it is made into a sliver which passes between upper and lower delivery-rolls, E E2.

The construction of the drawing-head, the means employed to properly direct and guide the belt of pins G at the delivery end, the mechanism for operating the drawing and delivery rolls and the belt of pins C, and the arrangement of the several parts are all fully shown and described. in my application for Letters, Patent led July 18, 1884, Serial No. 138,043, and no further description is here necessary.

As in the application last above mentioned, the belt of pins C is driven in the direction of the arrows by chain-wheels at its delivery end, and is carried at its receiving end by i chain-wheels a on a shaft, a'.

On the end of the shaft a is a pinion, a2, meshing into a wheel, ai, and on the same shaft or stud as the wheel a3 is a pinion, at, gearing into a pinion, a5.

into a wheel, a6, on the end of a shaft, al, which is at the delivery end of the rst belt of pins, B, and has upon it chain-wheels as, for driving said belt.

' At the receiving end of the belt of pins B arechain-wheels ci on a-shaft, am, and on said shaft is a wheel, a, gearing into and driving The pinion a5 gearsv a wheel, an, on the shaft of the lower feedroll, A.`

The mechanism herein described transmits to the rst belt of pins, B, a movement in the reverse direction to the belt C; but the operative portions of the two belts of course ymove in the same direction. The movement of the belt of pins B is slower than that of the belt C, and any mechanism which will produce this result maybe employed. The lower feedroll, A', is in xed bearings; but the boxes b of the upper roll, A, are movable in housings -b,fandA are loaded to the desired degree by springs b2, placed above them within the housings b', in a manner common to the upper feeding rolls of machinery for preparing brous materials. Forward of the feed-rolls isA arranged an indicator-scale, b3; and b* der; ignates a rock-shaft carrying an indicator, b5, registering thereon. At its front end the shaft b4 has a bearing in a cross-bant, and is connected by an arm,`b, and rod b8 with a crossbar or saddle-piece, b, the ends of which are attached to and movable with the boxes b.

By these connections the rising and falling of the upper feed-roll, A, will move the indicator b5 over n the scale b3, and the position whichV the indicator should occupy when the feeding is properlyv performed being determined, the attendant has only to glance at the indicator to see whether he is feedingtoo fast or too slow, and then regulate his feed accordingly. Y

' In'order to hold the ber upon the downwardly-presented pins of the belt B and to prevent its dropping off said pins, I employ a retaining apron or belt, G, composed of parallel rods c and chains c. This apron or belt is carried by polygonal rollers d d', and upon the Vshaft of the roller d is placed the trans- IOO mitting-pinion a5, which gears into the wheel a and thus drives'the shaft ai. The links of the' chains cof the retaining apron or beltv belt moves in the same direction and at the same speed as the lowermost portion of the v belt of pins B, thel rods of the retaining apron or belt receive the pins between them, and so retain the ber on the pins. The uppermost and operative portions of the apron-chains c are supported by tracks or rails d2.

In order to aid in detaching the ber from the pins of the rst belt, B, at the delivery 'end' thereof, I arrange within the said belt a clearing blade or plate, e, which is of a size to enter between the chains of the belt and between thel pin-bars. As here shown, this blade or plate is pivoted to the ends of arms f, which extend over the shaft ai, and are pivoted or fulcrumed at g, and are provided with downwardly-projecting toes h. Only one arin f is shown in the drawings; but one is arranged near each side of the belt of pins; As the pin-bars of the belt pass the toes h they act successively upon them, and so raise the arms j' and lift the clearing blade or plate e clear of the pin-bars. As each barin succession releases the toes 7il the blade or plate falls, and, descending between two pin-bars, clears the fiber from their pins.

The belts of pins are each composed of' parallel cross-rods z', armed with combing or hackling pins fle, and fitting loosely in the links of two endless chains, i', in which they are iree to turn. V

Secured fast on the ends of the pinbars Ai are dogs the form of which is best seen in Figs. 5, 6, 7, and S, and which have in their outer sides notches or chambers t, and projecting from their outer sides studs or pins i* i5, thelatter being the shorter of the two, as shown in Fig. 7.

The chains i may be of any suitable con-l struction; but I prefer to use chains very similar to that shown and described in my Letters Patent No. 108,473, dated October 18, 1870, or like that shown and described in my Letters Patent No. 311,310, dated January 27, 1885.

Extending forward ot' the receiving' end of the first belt, Bare rails in, which support the uppermost or returning portion of the chains.

Parallel with the rails m extend rails m provided with ribs or tongues md, which receive the channels or notches of the dogs i2, and

on which the dogs slide and are guided and held with the pins in operative position.

Adjacent to the chain-wheels a" and shafts am, at the receiving end of the first belt of pins, B, are two cams, n n', the forms oi' which are shown in Fig. 5,and on which bear the studs i i5 of the dogs as the chains pass around the wheels ai. By these cams the pin bars are turned and held in proper position for the pins to enter the iiber s, and are supported against backward movement as they enter the ber and until the channels or notches i3 of the dogs engage the end ot' the guiding-rail m ri, by which the bars are held against turning` throughout the operative portion of the belt.

As shown best in Fig. 6, the guiding-rail or guide ym. in* is extended forward of the wheels a?, and as the belt of pins passes the wheels as its line of travel, instead of conforming to the circumference of the said wheels, is prolonged inl a direct line beyond said wheels.

At the -forward ends of the guiding-'rails in mit are chain-supports n?, inclined upwardly and forwardly, and extending at a corresponding inclination and parallel therewith are stationary cams a?, which are arranged to act ou the studs or pins i* of the dogs As the chain-dogs i2 leave the guidingrails m mit, the chains pass directly upward and forward along the chain supports or tracks n2, and at the same time the studs i" come in contact with the cams n3, and the pin-bars t' are thus held against turning` in a direction to swing the pins forward. By said cams the pins are preventedfrom swinging outoi` the liber as they leave it, and are withdrawn directly upward, thereby clearing themselves of tow. The chains of the second belt of pins, C, are supported in their operative movement by supporting rails or tracksj. at opposite sides of the machine, and extending parallel therewith are guidingrails Z", having tongues kit, which iit the channels or notches i3 of the chain-dogs, and thus hold the pin-bars against turning during the forward operative travel ofthe belt. The returning or lowermost portions of the chains are guided or travel on supporting-railsj', and parallel rails or tracks j* support the studs fi* of the chain-dogs i2 and keep the pins at a rearward inclination.

Rearwardly of the cliaiirwlieels c are chain guides, supports, or tracks j", extending forward and upward at an inclination corresponding to the inclination of the supports ortracks n2, and stationary cams Zt, correspondingly inclined and adapted to act on the studs 'it of the chain-dogs.

Adjacent to the lower part of the cam 1*, and extending below and forward thereof, is a second cam, Z', adapted to act on the studs i? of the dogs.

Before the chains ofthe belt C reachthe guides or supports j the studs i4 of the dogs drop off or leave the end ofthe supporting rails or tracks viii, and by the studs ibearing on the cams l', the dogs are swung round to enable their studs fi to enter under the cams 1*, and as the chains pass upward their pinbars 'z' are held against turning backward by the studs i* of the dogs bearing on the inner side of the said cams Ziff, and consequently the pins are kept in vertical position and are raised vertically into the ber s, instead of being swung into the ber. As the dogs approach the upper part oi the cams lilthe studs i5 also come in contact therewith, and the bars` t' and pins are thus prevented from being swung forward as they enter the fiber and until the notches or channels ifi obtain a firm hold on the guiding-rails kit.

By the above described arrangement of guides or tracks and cams for the chains and chain-dogs a very close nip on the ber is maintained by the two belts of pins.

The pin-bars may have dogs secured on both their ends, or each bar may have a single dog, the dogs of alternate bars being on one side of the belt, and the dogs of intermediate bars being at the other side of the belt.

At the two sides of the machine are tracks or guides and cams, which are similar, and which act simultaneously on the dogs at opposite ends of pin-bars.
