ROBERT J. GILMORE, OF PROVIDENCE, RHODE ISLAND.

RlNG-TRAVELER MACHINE.

SPECIFICATION forming part of Letters Patent No. 310,577, dated January 13. 1885.

' Application filed September 21,1883. (X model.)

To all whom it may cancer/r.- Be it known that 1, ROBERT J. GILMORE, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Ring-Traveler Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or; figures of reference marked thereon, which form a part of this specification.

This invention relates to machines for making ring-travelers or other'analog'ous articles; and it consists, first, of two pivoted and adjustahle shaping-formers,which receive simultaneous movement by means of toothed levers operated by a single cam secured to the driving-shaft, in combination with suitable feeding and cutting-off mechanism.

The invention consists, secondly, of an ad- -justable and yielding plunger, which rests against the traveler while it is being formed.

The invention consists, thirdly, of a hori zontal arbor provided withmeans for intermittently moving the same endwise and means for adjusting the arbor radially, all as will be more fully hereinafter set forth.

The object of this invention is to provide a machine with means for producing ring-travelers in abetter and more expeditious manner than has been done heretofore. ,In the accompanying two sheets of drawings, Figure 1 represents a front elevation of the machine complete as in use. Fig. 2 is a rear view of the same. Fig. 3 is a detail view of the toothed levers which connect with the shaping-formers. Fig. l is a vertical section through the frame, plunger, and its plate.

Said figure also includes a front view of the same without the plate. Fig. 5 is a vertical longitudinal section showing the crank device. Fig. 6 is an end view of the same. Fig. 65- is an enlarged sectional view, showing the horizontal arbor and its bearing. Figs. 7, 8, 9, and 10 represent various forms the stock assumes during its formation into a ring-traveler. These views also show certain details of the forming parts and yielding plunger. Fig; 11 is a ring traveler complete. Fig. 12

(Sheet 2,) is an enlarged vertical transverse section through the center of the machine. Fig. 13 is a partial horizontal sectional view. Fig. 14 is a partial view of the frame, showing one of the openings therein, within which one of the shaping-formers is located. Fig.

.15 is a front view of one of the shaping-formbushing which carries the steel plate within I which the center arbor is mounted; and Fig. 22 is a front view of the plate itself.

The following is a detailed description of the invention:

A, referring again to the drawings, designates the vertical frame of the machine, which' is provided wit-h. bearings B for the main driving-shaft B. At each side of the frame, near its lower edge, are formed openings A, Fig. 14., adapted to receive the holder for the movable formers, &c.

E, Figs. 1 and 2, represents a cam on the shaft B. .This cam imparts intermittent motion to the lever K, and said lever like motion to the feed-rolls TT tlnrough the gear-train T T T.

It is a spiral spring, having one end fixed to the frame, and the other end secured to the lever K. This spring holds said lever against the end of the set-screw 7c. The object of this screw is to adjust and limit the length of stockto form the travelerfed along between the feed-rolls at each revolution. At the'longest feed the friction-roll 76 may rest against the face of the cam E; but as the feedis shortened so relatively is the distance increased between the roll and the face of the cam, this distance being gaged by means of said screw k. The segmental toothed arm of the lever K engages a gear-wheel, T, v (shown dotted,) which in turn is connected (by means of a pawl and ratchet, or otherwise, as common) with the larger gear-wheel T the latter meshing into the wheel T, secured to the shaft [1, carrying upper roll T is connected with the lower feed-roll by means of the set-screw T, which bears against a box carrying the upper rollshaft, as common. The stock a is intermittently fed along between the rolls T by means of said cam E, lever K, and the gear-train T T T, before described, D is a disk secured to said shaft,having an eccentric groove formed upon its face, within which is loosely fitted the ring D, adapted to connect with the plunger or cross-head I by means of the pin d"'. The pin may be secured-to the ring and fitted into the plunger. The eccentricity of the groove and. ring corresponds to the throw or stroke required. I I am enabled thereby to dispense with the link or other intermediate connection usually required in transmitting power from the crank to the plunger, &e., thus pen initting the reduction of the height of the machine.

O is a cam secured to the shaft 1; for the purpose of giving suitable motion to the lever F, the latter having a toothed segment, F. The lever F is fulcrumed at f to the frame. The lower portion, F", of said lever has an elongated opening, f i A similarlever (without the arm F) is mounted upon the frame, and connected with its fellow just described by means of the cogs f, all as fully shown in Fig. 3.

s-is the steel former, around which the stock z is bent to form the travelers 2', said former being secured within the arbor or spindleH, as fully shown in Fig. 12. A bushing, 1 having an enlarged center opening, 1), is re tained in position and secured to the frame A in front of thespi ndie H by means of the screw 0, passing up through the center projection or lug,V. A steel guide-plate, P, is fitted into the face of the bushing, having a center opening correspondingin size to the former s. In changing the formers, the screw 0 is loosened, after which thebushin g, wit-l1 its plate, is removed, when, after inserting another or different-sized former, 8, within the spindle H, aplate, I having an opening of the same size as the former s, is inserted within the bushing, and the latter then replaced within the frame and secured in place by said screw 0. Arbor H and formers are reciprocated by means of the cam-lug d, engaging the upper end of the lever d, (the latter being pivoted at d to the frame,) whereby the main shaft in its revolution causes said arbor to move endwise intermittently, a spring, d, returning the lever d, and thereby the arbor, to its normal position, all as fully shown in Fig. 12. A bearing or support, A, secured to the rear .of the machine, carries the arbor. Its outer end is counterbored to receive the arm H, the latter being splined to receive a key or feather secured to the arbor. By means of the arm H the former s is adapted to be slightly adjusted radially without removing said former from the spindle. A bolt, 71 serves to clamp the whole in position. I designates the main plunger, which is operated by the disk D, &c., before described. Said plunger is provided upon its front surface with the two adj ustablysecured cutters t. (See right-hand portion of Fig. 4.). 7c designates a narrow plunger mounted upon the front of the plunger I, and between the cutters 6*, Figs. 1, 4, and 12. Said plunger k is adaptedto rest upon the stock during the cutting aud shaping process. It is further provided with an adjusting-screw, i", and spring i is the plate which covers the front end of the plunger I.

\Vithin the frame-openings A are pivoted at O holders R, each of which is provided with I a slotted arm,R",adapted to receive the clamping-screw a". Said holders are further provided with the elongated openings 1-", Fig. 18, and rear projections, r".

G is the block, which is adapted to sl ide freely within the holder R. A projection, r", fits within the openinga. A plate, 1 secured to said projection serves to retain the parts in position.

9 is a stud or pin of said plate, adapted to engage the slots f of the lever-arms F F, thereby causing the blocks to move in unison with said levers.

U represents the stud shapers or benders, pivoted ate to the sliding block G. a shows an elongated opening therein, adapted to receive the clamping-screw a; and a is a screw which passes through the lug g of the block G, for the purpose of adjusting the position of the shapers relatively to the former s. The geared rolls T feed the stock along the guide at m and against the stop or gage Z, (see Fig. 1,) as common.

The machine operates as follows: Assuming that the formers, 850., have been properly adj ustedand the stock fed into position,now,by revolving the shaft in the arrow direction, the disk forces the plunger I downwardly,the end IOC of the supplemental plunger is resting against the stock during the movement, Fig. 7. N ow, a further movement causes the stock to be severed and bent downward by means of the cutters t, Fig. 9. During this latter travel, however, the plunger has remained stationary, owing to the compression of the spring 2'. At this point, while the crank is passing its dead-center, the cam O, by means of the lever F aud connections,causes the steel benders and shapers U to simultaneously move upward and inward, the points 8" thereof engaging the projecting end of the stock, Fig. 9, and bending them into shape, as shown in Fig. 10. A. further movement of the shaft B causes the cam d to engage the lever cl, which in turn connects with the arbor H, Fig. 12, thereby forcing the latter rearward and bringing the face of the former s flush with the steel plate P,thus causing the finished traveler z to fall into a receptacle or chute beneath, completing the revolution.

In Fig. 8 the plunger 70 is not shown, thus former s after the cutters i have performed their functions. It is obvious that travelers IIO thus produced must necessarily be imperfect; but by means of the yielding plunger 7; the work is rendered perfect and salable.

The arbor H and bushing l? are adapted to receive formers 8 having various sizes and shapes. The steel shapers U are also provided with means for adjustment, and further adapted to produce travelers having the ends bent square instead of hooking, as shown, by means of the pivoted and radially-slotted holder R.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The combination of the driving-shaft, disk D, plungers I is, pivoted lever d, arbor H, and former s, the parts being connected and operated substantially as described, and for the purposes set forth.

The combination of-the driving-shaft, disk D, plunger I, cutters i, pivoted lever 11, arbor H, and former a, substantially as described, and for the purposes set forth.

3. The combination of the driving -shal't, disk D, plungcrs I It, pivoted lever 11, cutters t, arbor H, and former s, substantially as de scribed, and for the purposes set forth.

71: The combination'of a frame, A, a driving shaft, B, two pivoted and adjustable shapers, U, sliding blocks or holders G,

toothed levers F havin arms F a lever F the cam O, secured to the shaft B, and the feeding and cutting-off means, all substanlength of stock, and the means, as described,

for connecting the plunger I and supplemental yielding plunger k with the drivingshaft B, substantially as shown.

6. The combination of the disk D, having an eccentric groove formed in its face, said groove being provided with ring D, the pin 11*, plungers I It, and former .9, said disk being fixed to the shaft, substantially as described, and for the purposes set forth.
