1. TQ all whoin it may concern:

Be it known that I, THOMAS A. EDISON, a

citizen of the United States, and a resident of West Orange, Essex county, New Jersey, .have invented certain new and useful-Improvements in Swaging-Machines, of which the following is a description.

My invention relates to swaging machines 1 and more particularly to an improved ap- .10

gitratus for fastening an article, such as v a -'amond splint, within a, holder or mounting therefor. I

. Considerable difliculty has heretofore been experienced in the manufacture of styli for reproducing phonograph records, in so seand corn aratively inexpensive machine is ob ection will be obviated and or other stylus within its holder may be quickly, effectively and economically accom- ,25

plished. It is to be understood, of course, that my improved machine is not limited to this use, as thesame is adaptedto effectively operate on other work. 1

In its preferred form, the machine comprises means for effecting the heating of the work, preferabl by an electric heating cur rent, so as to so ten the same, and means for swaging the heated and softened work. In the case of phonograph styli, the holder of the stylus is first heated and softened and is the stylus so that the latter will be securely and permanently fastened within the holder.

Other objects and features of my invention reside in the construction and combination of parts hereinafter more fully described and claimed.

In order that my invention may be more, clearl understood, attention is directed to 8". 1V is a view in side elevation, pa tl the action of my machine; and

Fig. 5 is a view similar to Fig.3 showing the holder and stylus after the holder has been heated and swaged.

Referring to the drawing, reference character 1 represents the frame or standard of my improved machine, this frame preferably being made ofcast iron and comprising two spacedlegs 2 connectedat the top by an integrally formed cross piece 3. The standard 1 is preferably secured, as by means of bolts 4 passing through the lower flanged ends of legs 2, to a wooden table .or bench 5. A vertical rodv 6 isslidably or re ciprocably mounted in the frame or standard 1, this rod extending through openings in the top cross piece 3 and the top of the table or bench 5. The lower end of the rod 6 is pivotally connected, as by means of a link 7, to a foot treadle 8 ivoted at one end 9 to a fixed support, such as the floor.

The rod 6 constitutes a work holder, the

upper end portion thereof being formed with an enlargement 12 provided with an axially; extending socket member 10. When the machine is to be used for fastening phonograph styli in their holders, the socket member 10 ispreferably rovided with a vertical cylindrical recess, t e bottom of which is located only a small distance below the upper end of rod 6, so that when a cylindrical stylus mounting or holder, as shown at 11 in Figs. 4 and 5, is disposed therein, a considerable portion of the holder extends above the rod 6.. The upper enlar ed portion 1'2 of rod 6 is formed with a plurality of radially disposed equi-spaced slots'13. Four such slots 13 are shown in the c n tructi n illu trated, the a j n such slots being disposed at angles of ninety degrees with respect to each other. Bell crank levers l4'arerespectively mounted in the slots 13 for pivotal movement about her-i- 5 nt axes has. by.
