IMPROVEMENT lN TWISTING AND SPOOLINTG MACHINES.

Specification forming part of Letters Patent N o. 132,155, dated October 15., 1872.

Improvements in Machines for Twisting and Spooling Hay-Rope, of which the following is a specification:

My improvements relate to that kind of machines which are employed for producing the hay-rope or cord used in founderies in the construction of cores for castings. My invention consists, first, in the combination, with the flier-frame, of a hollow journal, central shaft, and power-transmitting mechanism for rotating the screw which operates the travelingroller; second7 in combination, with the distributing or traveling roller and screw for operating the'same, of the reversing mechanism, hereinafter described; third, in the combination, with the flier-frame and traveling-roller, of a slotted guide-bar, a roller-supportsliding thereon, and a screw-shaft for operating the latter fourth, in the combination,with theflierframe and spool, of a couplin g-rod for connecting the spool to the flier-frame, so as to allow of its being readily attached or detached.

In the accompanying drawing, consisting of two sheets, Figure I is a sectional elevation of a rope-machine provided with my improvements Fig. II is a top-plan view thereof; Fig. III is a fragmentary end elevation; Fig. IV is a detached view of the traveling-roller; Fig. V is a plan view, on an enlarged scale, of the mechanisin by which the motion of the travelingroller is regulated; Fig. VI is a fragmentary elevation thereof; Fig. VII is a plan view of the mechanism by which the motion of the traveling-roller is reversed; and Fig. VIII is a detached View of the mechanism by which motion is transmitted to the screw operating the traveling-roller.

Like letters designate like parts in each of the figures.

A represents the stationary main frame of the machine, and B the revolving hier-frame Supported on the former by hollow journals b b1 resting in bearings a a. The dier-frame B is nearly rectangular, one of its horizontal portions being a iiat bar,`B, provided with a longitudinal slot, b3, Fig. VII. C is the spool upon which the rope is wound. It is arranged in the flier-frame so that its axis coincides with the axis of rotation of the latter, and is secured thereto in a manner hereinafter to be explained. The journal b ofthe flier-frame is constructed with an axial recess or bore, c, for the introduction of the rope, as clearly shown in Fig.v

I. c1 is a guide-roller, arranged in the journal b in line across the bore c, and o2 is a similar roller arranged in the corner of the flier-frame near the portion B thereof. d is the traveling-guide roller, by which the rope is distributed upon the spool. It is attached to a hanger, d1, hinged to a sliding piece, d2, moving on the portion Bl of the flier-frame in the slot b3 of the same. The journal b1 of the Hier-frame is hollow, so as to receive a shaft, e, which projects out of said journal on both sides. e1L e2 are two pulleys, secured respectively to the outer ends of the journal b1 and shaft e, as clearly shown in Fig. I. Motion is imparted to the pulley e1 by the driving-belt, while the pulley c2 is provided with a band-brake, f, operated by a weighted arm, f1, and foot-leverfz, for a purpose hereinafter to be explained. (See Figs. I, II, and III.) g is a screw arranged longitudinally above theportion Bl of theflier-frame, and supported in bearings g1 g2 attached thereto. It passes through the sliding piece d2, to which the traveling-roller d is hinged, so that by its rotation said sliding piece and roller are moved back and forth. h and h1 are short shafts arranged parallel to the screw g on each side thereof, and supported in the bearings g2 g3, and geared together by two spur-wheels h2. t' is a spur-wheel secured to the screw g, and il i2 two spur-wheels meshing therewith and turning loosely on the shafts h and h1, respectively. The shaft h carries a chain-pulley, k, triangular or of other suitable shape, to which motion is transmitted by the endless chain k1, from the chain-wheel k2, secured to the inner projecting end of the shaft e. k3 is a tensionpulley, over which the chain k1 passes. adjustably attached to a slotted bracket, h4, secured to the dier-frame B. l l', Figs. V and VI, are two clutch-couplings sliding on keys on the shafts h h1, respectively, the spur-wheels il i2 being provided with suitable projections or teeth to engage therewith. In Fig. V, VI, and VII, N is the shifting-lever, arranged under the clutch-couplin gs l l', pivoted to the portion B ofthe hier-frame at m, and provided with two upwardly-projecting pills, m1 'm2,

It is which engage with said clutch-couplings. N is the reversing-lever pivoted to the portion Bl of the flier-frame at n on one side of the slot b3, its arms extending to near the ends of this slot. The lever N is constructed with two inclined or tapering ends, nl n2, one of which always obstructs the slot b3. o is a spring-arm pivoted to the end of the lever N near the shifting-lever M, and provided at its end with a roller, o1, which can be made to engage with either one of two curved recesses, o2 o3, formed in the shifting-lever M. p is a square rod or bar passing longitudinally through the shaft e and spool C, and entering the flierframe at p with a round portion, so as to connect the spool securely thereto, while enabling the spool to move independently of the flier-frame. By withdrawing the rod p the spool is detached from the dier-frame.

The operation of my improved machine is as follows: When power is applied to the pulley el by the driving-belt, and the brake-pulley 62 is released by applying the pressure of the foot to the lever f2, the flier-frame B is revolved in its bearings, and the shaft c, chainwheel 7a2, and spool C, are carried along by frictional contact, so that their relative position to the flier-frame, and the parts attached thereto, remains unchanged. During such movement of the dier-frame there is no rope wound upon the spool, and the chain k1, shafts h h1, and screw g being at rest there is no motion imparted to the traveling-roller d. The operation of the machine is consequently limited to the twisting of the rope, which latter is introduced in the axis of revolution of the Hier-frame, and carried over the fixed guiderollers c1 c2 and traveling-roller d to the spool C, as clearly shown in Fig. I. When a piece of rope of suitable length has been formed, the operator who holds the loose end of the rope in his hands releases the foot-leverf2, when the weighted arm f1 applies the brake to the pulley c2, whereby the shaft e, chain-wheel 7a2, and spool O are arrested in their movement. The flier-frame B now travels on, while the spool O remains stationary, which causes the rope to be wound upon the latter. The chainwheel k2 remains stationary while the shaft h, attached to the flier-frame, continues its movement. Theshaft h is revolved by means of the chain k1 and pulley k transmitting motion to shaft h1 by the wheels h2. When the parts are in the position represented in Figs. V and VI the shaft h transmits motion to the screw g by the spur-wheels t il, the spur-wheel il being coupled to the shaft by the clutch-couplin g l. The screw g'being in this manner revolved, the slide d2, to which the traveling-roller d is hinged, is moved in the slot b3 in the direction of the arrow, Fig. VII. rIhis progressive motion of the roller d is so timed that the rope is evenly wound upon the spool by thel same. When the sliding piece d? strikes the inclined end nl of the reversing-lever N, the latter is swung on its pivot so as to assume the position indicated in dotted lines, Fig. VII, wherebythe roller of the spring-arm ois withdrawn from the recess o2 of the lever M, and is mad to engage with the recess o3 thereof.

' By this operation the lever M is shifted in such manner that the clutch-coupling l is thrown into gear with the spur-wheel i? while the coupling l and wheel i1 are disengaged. The direction in which the screw g revolves is thereby reversed, which causes the .lide d2 and roller d to travel backward toward the other end of the slot b3. When the sliding piece d2 strikes the other inclined end of the lever N its motion is again reversed in a similar manner.

When a spool has been filled with rope the coupling-rod p is withdrawn so as to release the spool, and an empty one put in its place, in an obvious manner.

I claim as my invention- 1. rllhe combination, with the dier-frame and its hollow journal b1, of the shaft c, pulley k2, chain k1, pulley k, and shaft h, substantially as hereinbefore set forth.

2. The combination, with the hier-frame, screw-shaft g, clutch-couplings l l, and connecting-gear for actuating said shaft, of the shifting-lever M and reversing-lever N, provided with spring arm o, substantially as hereinbefore set forth.

3. The combination, with the iiier-frame and slotted guide-bar B', of the screw-shaft g, travcling-roller d, and sliding support cl2, substantially as hereinbefore set forth.

4. rIhe combination, with the flier-frame, of the spool C, shaft e, and coupling-bar p, substantially as hereinbefore set forth.
