' SPRING` COMPANY, 0F MASSILLON, OHIO, A CORPORATION OF OHIO.
Applicatijn 4`tiled October M, 1921. Serial No. 507,649.
Be it 'known that I, EDWARD J. BAUM- oAn'rEN,".a citizen of the U 'ted States, 'residing at Canton, in the count of Stark and State of Ohio, have invente a new and useful Die, of whichv thev following is a specification.
This vinvention 'relates to dies and more i 'particularly to dies designed for applying clips to vehicle springs for clamping a plu# rality of spring leaves together. y e The objects of the invention are to provide dies of this character' arranged to bend the free ends of a clip over the top of a spring and clinch the same tightly upon the spring, holding the several leaves together. With these objects in view, the invention consists vin the construction and arrangement of parts, hereinafter described and illustrated inthe accompanying drawings, 1t
` beinglunderstood that various changes in the form and detailsof construction may be made Within'the scope 'ofthe appended claims.
is illustrated in the accomparying drawings, in which- Figure 1 1s aisectional view through-the die showing the same in the initial position;
.Fig 2, a similar view showing the iirst `operation, the bending dies being shown in the actf'of bending the freq ends of the clip 'over-the top of the spring;
Fi .3, a side elevatlon of the die show- Aing t e last operation, the clinching die being shown clinching the ends of the clip upon the spring; ff,
Fig. 4, a section on the line 4:-4, Fig. 3;c Fig. 5, a perspective view of one of the guides for the bending dies;
corresponding parts throughout thel several D igures` of the drawings.
l The base 1. 's .provided asocket-'2 within which the anvil 3 is mounted, said anvil being provided with arece 4 to ae- A preferredembodiment of the invention v Fig. 8, an enlarged perspective view f- 4one ofthe clips. o j

commodate the head of the rivet' 5 by means of which the clip 6 is attached to the lower leaf of the spring 7. o
This clip is U-shaped as best shown in Fig. 8 and is provided with the central aperture 9 for the reception of the rivet 5 by meansi'of which the clip may be attached to the lower leaf of the spring. rllhe rms 10 of the clip extend upwardly above the top leaf ofthe sprincr as best shown in Fig. 1. The bending d1es 11 are slidably mounted upon the top of the base l'and are provided with the V-shaped grooves-12 arranged to slide upon the V-'shaped guide-ways 13 of the guides 14,' which guides are attached upon opposite sides oi the base as by the bolts 15. Each of the bending dies is provided with the' inwardly disposed, reduced portion 16 arranged to engage the free extremities of the arms 10 of the clip, as will be later described.
The base is provided at each end with the upright portions 17 having the bores 18 extending from the outer side to a point vnear the inner side' thereof, said bores communi eating with, and being in alignment with the reduced bores 19. -Rods 20'are carried by the bending dies, and extend outwardly through the bores 18 and 19, a coil spring 21 being located around each of said rods, being interposed between the shoulder 22 vandsthe head 23 ofthe rod.
It'. will, of course, be understood` that the base is mounted in any suitable type of press, the presser head 24 being arranged to be moved vertically with reference thereto. The depending cams 25 are l0- cated near the opposite ends of the presser head 24 and arranged to operate the bending dies, moving the same inwardly against the pressure of the springs 21.
' In operation, aA clip is attached to the lower leaf of a spring by means of a rivet and the spring 'is placed in-the device in the position shown in Fig. 1, the clip resting upon the anvil, the head of the rivet extending into the socket 4 of the anvil, the free ends of the arms 10 of the clip extending upwardly beyond the top of the spring.
The presser head is then moved downwardly by any usual means, the tapered lower portions 27 of the cams 25 starting to move the bending dies 11 inwardly and as the curved portions 29 of said cams engage the bending dies, the same are moved quickly inwardly into the position shown in Fig. 2, bending theextremities of the armsof the clip toward each other as'shown in said fig.
ure, F urther'downward movement of the presser head does not change the position of the bending dies, as the vertical faces 28 of said cams are then in-engagement ywith-the rear surfaces of the bending dies, holdingr the same in the position shown in Fig. 2,
while the clinching die moves downwardly into -engagement with the over-turned endsA of the clips, pressing the same tightly against the upper surface of the spring and clinchsecurely upon the spring, as
ing the clip shown in Fig. 7.
; pliction of my invention, many changes 'in 'form' and construction may made, as circumstances requlre or experience.` suggests,
1 55 without departing from the spirit of the in- It will thus be evident that with the present device, the clip is bent around the spring i vention, within thev scope of the 'appended' claims.
. I claim l. A device for applying clips to springs including astationary base bending dies for bending the; free ends ofa clip over they springfa presser head, cams upon the presser head for 'operating the bending dies,
said base being provided with apertures to receive the cams and a clinching die upon the presser head for clinching the ends of the clip.
a 2. A device for applying clips to springsV including a stationary base, a pair of opposed, slidable bending dies mounted in the base for bending the free ends of a clip over the spring, spring means for normally holding said bending dies in the inoperative position, a movable presser head, means upon `the presser head for operating the bending dies, the base being provided with apertures to receive said operating means and a clinchingdie uponthe presser head for clinching the ends of the clip.
3. A device for applying 'clips to springs including a stationary base, a pair-of'opposed, slidable bending dies mounted in the base for bending the free ends of a clip over thespring, spring` means for normally hold: ing'isaid bending dies in the inoperative position, a movable presser head, cams upon said presser headfor operating the bending dies when the presserhead islowered, the base beingI provided with apertures to receive said cams and a clinching die upon the presser head for clinching the ends of the clip.
4. A device for applying clips to springs including a stationary base, a pa1r of-op: posed, horizontally slidable dies mounted -1n the base for bending the free ends of a clip over the spring, spring means for normally holding said bending dies in the indperative position, a vertically movable presser head, cams upon said presser head for operating the bending dies when the 'presser head'islowered, the; base belng provided wlth apertures to receive said cams and a clinching die upon the presser head for clinching the ends of the clip after the same have bee bent by the bending dies.
In testimony that I claim thev above, I-
have hereunto subscribed my name.
EDWARD JQ BAUMGARTEN.'
