CHARLES T. RIETSOHY, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO JAMES IRWIN BARNHURST, OF SAME PLACE.

MACHINE FOR ATTACHING FORKS TO UMBRELLA STRETGHERS.

SPECIFICATION forming part of Letters Patent No. 383,075, dated May 15. 1883.

I Application filed February 4, 1888 Serial No. 263,053. (No model.)

To aZZ whom it may concern:

Be it known that I, CHARLES T. RIETSOHY, a citizen of the United States, residing at the city and county of Philadelphia, and State of Pennsylvania, have invented certain new and useful Improvements in Machines for Attach ing Forks to Umbrella-Stretchers, of which the following is a full, clear, and exact description, reference being had to the accompanying 1o drawings, of which Figure 1, Sheet 1, is a side elevation. Fig. 2 is a transverse vertical section, as on line a b, Fig. 1. Fig. 3, Sheet 3, is a longitudinal vertical sectional elevation. Fig. 4 is a trans- :5 verse vertical section, as on line 0 d, Fig. 1.

Fig. 5, Sheet 3, is a plan view of the anvilblock and connections detached. Figs. 6, 7, and 8 are transverse sections through the center of the die, showing the several successive 20 positions into which the fork is bent. Fig. 9 is a like section through the rear of the die and slotted projection on the lower end of the reciprocating hammer, showing the position of the limbs of the fork when said projection Fig. 10 is a view of one of the blank forks. Fig. 11 is a view of a portion of an umbrella-stretcher with attached fork. Figs. 12-, 18, and 14 are perspective views of the dieblocks detached. Fig. 15 is a lower end view of the reciprocating hammer. Fig. 16 is a perspective View of the sliding piece and vertical cam-blocks secured thereto. Fig. 17 is a transverse section, as on line 6 f, Fig. 1.

The nature of this invention is an organiza- 3 5 tion or combination of mechanism whereby the usual blank sheet-metal forks may be readily bent up and attached to the ends of the fluted or Paragon frame umbrella stretchers, in order to form the lateral lugs to which 0 the ribs are pivoted.

The invention, as generally stated, consists in the combination, with a recessed anvil or die, of a reciprocating hammer arranged with relation thereto and provided with a bifurcated or slotted projection and a stud on its lower end in line with said die, and a springcontrolled plunger working in said hammer, together with transversely-reciprocating wings or jaws arranged and operating with reference to said die and plunger, whereby upon the bifurcated sheet-metal blank or fork and the stretcher being placed in proper position upon said die and the reciprocating hammer caused to descend the said stud'and slottedprojection will impinge against the stretcher and 5 fork, respectively, and force the same into the die, thereby turning the said fork up around the sides of the stretcher and expanding the limbs thereof, whereupon the transversely-re= ciprocating jaws, being forced together against the upturned ends of said fork, bend said ends horizontally. Said jaws immediately returning to their former position, the reciprocating plunger, which works in the hammer, descends and forces said horizontally-bent ends of the fork down into and against the sides of the stretcher. This completes the operation, and the parts resume their normal position for a succeeding one.

The invention consists, also, in certain details of construction, which will be hereinafter fully specified, and pointed out in the claims.

Referring to the annexed drawings, A represents the framework of the machine, consisting of the bedplate a and slotted standard 7 5 a". The latter is provided with recessed forward projections, a which form, in conjunction with the recessed pieces a, boxes or guides for the vertically-reciprocating hammer B. The lower end of this hammer has formed or secured thereto two studs or projections, b If, one of which, if, is slotted or bifurcated, as shown. To the bed-plate 0/ is secured a rectangular anvil-block, G, which contains a die,

0, in line vertically with said hammer and 8 its studs. The construction of this die will be hereinafter particularly described.

Within the hammer B is a longitudinal opening, b in which. is contained a thin rect angular plunger, b which is kept normally 0 elevated by means of a spiral spring, 72 which bears against an offset, If, near the bottom of the recess, and against a vertically movable head, b, to which the upper end ofsaid plun ger is connected. In order to prevent the 5 plunger from being forced out of the opening I), the head b is provided with a longitudinal slot, 1)", through which and the hammer B a pin, 1)", is inserted.

Within the slotted standard a there is piv- 10o oted a lever, D, whose short arm d is connected with the head I) by means of links (P. The long arm d of this lever has a lateral longitudinal slot, d, through which passes the screw-threaded shank, (Z of a spud, 01, on one side of the arm 6?, which spud is secured in place by means of a jam-nut, 41 that is screwed up on shank, d against the opposite side of the arm.

Pivoted in the standard a above the lever D, is a lever, E, whose forward end, e, is connected by means of links'c with a plunger, 6 working in holes a in the projections a just in the rear of the hammer B. On the opposite end of said lever E is a downward extension, e, having lateral lugs e to which is pivoted a short vertical lever, 6, whose lower arm has an inward projection, e, and against whose upper arm and the end of lever E bears a small compression-spring, e

In the block G, in line vertically with the plunger 6 is a hole, 0 which contains a sliding piece, 6 The latter is kept normally elevated by means of a spring, 0 which bears upon the bottom of the hole 0 and extends into a recess, 6, in said piece. The plunger 0 rests upon the top of the piece 6 and is practically a continuation thereof.

To the opposite upper sides of said piece 6 are secured two vertical blocks, e, whose lower ends, a, are oppositely beveled, as shown. These beveled ends 0 impinge against the correspondingly-beveled ends f of horizontal blocks F, which reciprocate in guideways in the anvil-block G. In the top of the latter, on each side of the die 0, is a transverse block, G, whose inner or forward end has formed or secured thereto a wing or jaw, g, which normally extends to or nearly to the edge of the central recess, 0, in the die. On the under side of each of said blocks G, near the rear end thereof, is a downward projection, g*, which extends into a space or channel,c*,in the anvil-block 0. Against thisproj ection g and the opposite recessed wall,c ,of said channel 0 bears a spring, 0, which keeps the block G, or, rather, its jaw g, normally extended and away from the die-recess, c as shown clearly in Fig. 4. At a point, x, between the bloeks F and G is pivoted a small lever, H, whose arm h is loosely connected with a pin, on the block F, and whose other arm, h fits within a recess, 9 in the block G.

The die 0 is detachable from the anvil- .block 0, as seen, and consists, preferably, of

ner edges of these plates are offset at y, as

seen in Fig. 5, so that a blank, 1, may be readily placed upon the die, within the space 2, formed between the offsets.

The above is a general description of the construction of the machine. Its operation is briefly as follows: The blank 1 is first slid sidewise into the recess 2, and the stretcher 2 is placed upon the same with the curved side downward, the end of said stretcher abutting against a rear projection, c. The arm d of the lever D is then elevated by any suitable mechanism operated by foot or other power, and the hammer B is thus caused to descend, the stud b thereupon pressing the stretcher down into the die, and consequently the blank 1, thereby bending the latter (in block 0') into a U shape around the stretcher. The slotted stud or projection b at the same time strikes the limbs 1 of the blank and bends the same outward, as shown. The spud d on the side of the lever-arm d as the latter ascends, strikes against the curved projecting end 6 of the vertical spring-controlled lever e on the end of lever E, and slightly elevates the latter, thereby forcing down the plunger 0 and therewith the piece 6 and its eamblocks e, which latter press the contiguous blocks F outward. The levers H, connecting said blocks F with the spring-actuated blocks G, force the latter inward, and the jaws g on the ends thereof thus bear against andforce the upturned ends Z of the forks inward or horizontally, as shown in Fig. 7. The spud d as it ascends being disengaged from the curved end of lever e", the larger lever, E, and coacting parts resume their normal position,whereupon, as the arm of lever D further ascends, the plunger b is forced down against said horizontal ends I, and presses the same downinto and against the inner sides of the stretcher, as clearly seen in Fig. 14. The lever D now being released, the parts resume their normal position for a succeeding operation, and so on continuously. By means of the slot d in the lever D the position of the spud 01 may be readily changed, in order that it will properly strike the spring-lever projection 6 when either the latter or the spud becomes worn.

I I are adjusting screws and nuts for limiting the throw of the levers D and E, respectively, and J are like screws and nuts for adjusting the movement of the spring-actuated blocks G.
