IMPROVEMENT IN CASTING, uMBRELLA-TIPS, ac.

Specification forming part of Letters Patent No. 166,282, dated August 3, 1875; application tiled April 19, 1875.

To all whom it may concern: y

Be it known that I, AnoLPHUs LIGIBEL, of Jersey City,in the county of Hudson and State of New Jersey, have invented an Improvement in Casting Umbrella Tips, Heads, and Laps, of which the following is a speciiication:

Ei'orts have been made to cast the laps or connecting pieces upon the ribs of umbrellas; but they have not been successful, in consequeuce of the inaccuracy of workmanship.

In the manufact-ure of umbrella-frames it is necessary that the distance between the hole at the end for the crown-wire and the lap or joint for the stretcher be exactly the same in each rib, and that the holes be parallel with each other,- otherwise the ribs will not lie close to and parallel with the stick or handle.

My machine is made for the purpose of rapidly casting the tips, heads, and laps upon umbrella-ribs, and at the same time insuring great accuracy in the manufacture.

I make use of a machine somewhat like a type-casting machine, and combine therewith a compound jaw or mold, of' an internal shape corresponding with the external shape of the tip, head, or lap,and a movable mandrel, forming a core for the hole that is made in the lap, head, or tip, when cast.

I also employ a gage to determine the position of the lap, tip, and head in relation to each other.

In the drawing, Figure lis a front elevation of the machine. Fig. 2 is a plan. Fig. 3 is a plan view of the lower die, showing a rib in place for having a tip cast thereon; and Fig. 4 is a cross-section of the dies as closed, with Fig. 5 is a plan view of the lower die, with a rib in place for having a lap cast thereon.

The frame a carries the bath b, of type or similar metal, that is to be kept in a melted state by gas-burners or otherwise; and c is the actuating-shaft, that is provided with the cam d, acting upon the lever d to operate the pump e through the agency of the lever e', link f, and spring f', in a manner corresponding generally to that in a typecasting machine; and

a bent lever, g, cam 3, spring 4', lever g', and sliding pointed valve working within the nipple z' serve to close the orifice of said nipple when the molds are drawn away. The mold-V v One is in the adjustable block o1, that is hinged at 18, and positioned4 by 4the screw 20, and clamped by the screws 19. The other half of the mold o is fastened to the swinging head o2,

that is connected by the frked joint 48 to the block o1, and positioned by the end ot' such head oZ passing through the joint-block 28, and being clamped therein, when in place, by the screw 13. Upon the A.mold-frame h is a bent lever, r, pivoted at 16, and swinging behind the guide-bar s by the action of the link s', that is attached at the lower end I7, at a distance from the pivots 4 of the frame h, and at the upper end to the'said lever r, so that, as the mold-frame is swung back toward the nipple i upon the bath b, the bent lever r will be pulled down at its moving end, and, by the link u, will close the mold. This link is pro vided with the adjusting rod and nuts u', the

horizontal end of'which rod passes into a hole in the head o2, and is retained by the notched lever c.

This construct-ion. allows the link to be dis connected from the head, so that that can be swung back to open the mold for cleaning or otherwise.

The molds themselves are made ofthe shape required for the tip at one end, .and the head of the other, or for the lap in the middle ot' the rib. (These forms are represented in the detached views.)

It is preferable to cast the middle lap or joint-piece first, and in that case the straight `steel wire is passed in between the molds o and the end stops against the adjustable gage t upon the arm 2l, the faces of the molds containing half-ronnd grooves to receive such steel rib, and the mold being shaped as shown to form the lap; bul-.it` isupreferable, both on account of expense and to insure accuracy, to cast the lap with the joint-hole in it, and for this purpose a pin, 24, is inserted up through the lower die, and thc end passes into a hole in the upper die, so that the metal will be cast around that pin. (See Fig. 4.) This pin has to be Withdrawn from the lap or tip, and for this purpose the lever 26 is employed, and the link 27 to the lever fr, so that the pin is projected up through the mold as the mold closes and moves toward the teat on the bath of melted metal; and after the tip, head, or lap has been east by the jet of melted metal forced into the mold by the pump, and the mold is being drawn back and opened, the pin is drawn down out of the hole in the cast lap or tip.

In casting the tip and head, the steel rib is insertedinto the mold in the direction shown in Figs. 3 and 4, and the lap rests upon the adjustable gage t, so that its exact position is determined in relation to the tip that is cast v upon the end of the rib.

. The arm 21, upon which the adjustable gage in Fig. 3; or a second arm may be provided.

I claim as my inventionl. The two-part mold o, connected respectively to the swinging mold-frame h and swinging head o2, in combination with such frame h, swinging head 02, bent lever r, and link u, for opening and closin g the mold, substantially as specified.

2. In combination with the two-part mold o, the pin 24, lever 26, link 27, lever fr, and link s', as and for the purposes set forth.

3. The combination, with the molds o and casting mechanism, of the adjustable gage t and arm 2l, for positioning and holding the rib, as set forth.

Signed by me this 14th day of April, A. D. 1875.
