Letters Patent No. 108,742, dated October 25, 1870.

IMPROVEMENT IN MACHINES FOR MAKING UMBRELLA-CONNECTIONS.

The Schedule referred to in these Letters Patent and making part of the same.

I, Enwnv Wrenr, of the city and county of Philadelphia and State of Pennsylvania, have invented an Improved Mode of Making Umbrella-Connections,,

of which the following is a specification.

The nature of my invention consists in rolling the connections into form by passing sheet metal between a series of properly-grooved rollers, after which they are finished in the present usual mode, and attached as connecting-joints to umbrellas and parasolsQ To enable those skilled in the art to make and use my invention, I will proceed to describe the construction of the machine and mode of operation, reference lieing had to the accompanying drawing-in which- Figure 1 is an elevation of a pair of'rolls.

Figure 2 is a cross-section through the lower roll.

Figures 3, 4, 5, 6, and 7, show sections through the connection at diiferent stages of the operation.

Figure 8 shows the connection finished and secured to the rib of the'umbrella.

Figure 9 is an end view of the same.

I will first state that the connections as now made are cast of brass into theform shown in fig. 7 They are afterward out off in sectionsh', (see fig. 8,) drilled,

and the wings S S are clamped upon the rib K.

My modeof manufacturing is this: Fig. 1 shows apair of rolls, B B, geared together and driven by power, as used by metal-workers.

The upper roll B has beads of the shapeshown, O

D E G, fitting into'certain shaped grooves, G D E G, in the lower roll.

A piece of annealed slieet brass, or othermetal, of section fig. 3, and it may be one foot to one hundred feet long, is passed through form 0 O, which gives it l the shape, fig. 4. It is then passed through form coming out in shape, fig. 5. 1

The two sides are then flattened together by form E, as in fig. 6.

The serrated edge is then formed in grooves G, a

sectiont-hrough which is shown in fig. 2, the strips of brass coming out'as shown in side view, fig. 7. I

The wings S S are thus made of more uniform 1 thickness than by the usual mode. of casting.

The connections h are then sawed oft, finished, and secured to'the steel rib K in the usual manner.

I claim as my inventiona 1. The particular-devices upon-the rolls B'B, as indicated by the letters 0 D E G,'and their counterparts, for molding and notching a strip of metal, for the purpose herein set forth.

' 2. The mode herein set forthof manufacturing umbrella-connections by first preparing a strip or ribbon of metal, of the proper width and thickness, then passing it successively through the several shapingrolls, and:finally dividing the said strips into sections,

as that shown in fig. 8.
