BEAD FORMER .Filed April 4, 1927 2 Sheets-Sheet 2 in Fig. 5.

Patented ct. 22, 1929 UNITED STATES ROBERT BEARDSLEY, OF CHICAGO, ILLINOIS BEAD FORMER Application filed. April 4, 1927. -Serial No. 180,927.

Une of the objects of my invention is the provision of a new and improved embossing or bea-ding device, which will be simple, inexpensive, durable, reliable, eliicient and sat- 15 isfactory for use wherever found applicable.

Many other objects and advantages of the construction herein shown and described will be obvious to those skilled in the art from 'the disclosure herein given.

To this end my invention consists in the novel construction, arrangement and combination of parts herein shown and described, and more particularly pointed out in the claims.

ln the drawings, wherein like reference characters indicate like or corresponding parts:

F ig. 1 is a plan view of one form of my improved embossing or beading device;

Fig. 2 is a section taken on line 22 of Fig. 1;

Fig. 3 is a top plan view of another' form of beading device;

Fig. 4 is a sectional view taken on the line 35 4-*4 of Fig. 3;

Fig. 5 is a sectional view of a lamp shade prior to beading; and

Fig. 6 is a detail sectional view of a lamp shade showing the bead completed.

My improved apparatus for forming the bead upon the formed blank A comprises a base plate 1 upon which is mounted a holder 2 having a frustro-conical aperture 3 conforming to the shape of the formed blank A Secured to the base plate 1 and concentrically disposed in the aperture 3 is a plate 4 adapted to support the top blank B when the same is placed in the aperture 3 in the manner illustrated in Fig. 2. As

shown, the formed article will project above the holder 2 so that its upper circular edge will be disposed in alignment with arcuate grooves 5 formed in a pair of arcuate levers which are pivotally secured to the base plate 1 by a bolt 7, the free end of the levers i3 being provided with handles 3 whereby the levers may be swung into and out of the positions wherein they are shown in Fig. 1.

Projecting upwardly from the base 1 and centrally disposed with respect to the aperture 3 is a pin 9 having a portion 10 of reduced diameter. Rotatably journaled upon the portion 10 is a bracket member 11 which carries a pin l2 pivotally securing a lever 13 to the bracket member, the longitudinal axis of the pin 12 being disposed at right angles to the longitudinal axis of the pin 9. Rotatably ournaled upon the lever 13 is a wheel 14 which may be rolled around the inner surface of the formed blank A to ex`1 pand the marginal portion C thereof into the annular grooves 5, which will form a bead 15 as shown in Fig. 2. As shown in Figs. 1 and 2, a latch member 1b pivotally secured to one of the arcuate levers G may be employed to lock the levers in the positions wherein they are shown in Fig. 1. After the bead 15 has been formed, the levers (3 are swung out of the positions wherein they are shown in Fig. 1 and the bracket member 11 together with the lever 13 and the wheel 14 are removed from the holder 2. From this it will be apparent that the formed blank A can be quickly placed in position for beading the marginal portion C or removed from the device.

To prevent distortion of the formed article when the bead 15 is being produced and to hold the formed articles against displacement relative to the holder 2, l preferably provide a weight 17 adapted to be inserted into the formed blank A to hold it in engagement with the frustro-conical surface of the aperture 3. The weight 17 is preferably provided with a plurality of eyes 18, or the equivalent, whereby the operator may lift the weight from the holder 2.

It will be apparent from the foregoing that in the use of my improved device, the formed blank A is first placed in the holder lwhich the projecting porti y end of said handle havin :i ball therca f is grasped and rotated so that the roi `the shade at this end and i 3 and the weight 17 then positioned to hold the blank in place. The arcuate lo' ers (i are then moved to a closed posi on to eiibi'ace the marginal edge C ot the formed blanlr as shown in Fig. 1, and in order to form the bead 15, the Wheel 14 is rotated iii the grooves pessing` a portion oil' the blank therein, as s own.

In Figs. 3 and 4, I have shown another torm of the invention which comprises a chainbered part 19 having inner' wall shaped Vto smoothly engage the outer periphery ot the shade but bei* g slightly shorter .u formed blank shade A so that the sh project therebeyond a suitable diem-nce An inner sleeve 2O is removably positioned within the shade after 1t has been placed in the mold, this sleeve being ot substantially the same length as the part 19.

A rino member made in one ..iore secn 7 I tions, there being two parts shown, ...s at al ispressed or rolled. The pe pivotally mounted upon an upi' and 'have projecting` handle whereby they may be swung into or out o operative position and held in place during the embossing. A

A roller having` a convex j ieriphera to cooperate with the annular groove in the ring is mounted upon a handle 26, the

is mounted in a spherical socket bcari whereby the roller may be given a uni v 1sal movement. Springs 29 mounted upon the tightening bolts 30 and positioned betw the clamping plate 81 and tho serle. 28 so that the bearing` for t be adjusted when desired.

19 and 20, the hand grip or 1.o

engages the inner periphery oit the proie portion of the shade and cupi la it radially outwardly into the t in the ring 21-22. This The shade may then be removed troni the mechanism and treated in any su `able manner, dependent upon the purpose 'lor which it is to be used.

It will be apparent 'from the foregoing that I have provided a new ai l inproved device which will prove extremely use'lul in embossing or beading formed lamp shades. It will also be readily apparent that the formed shades may be quickly and rerflilj-J placed in the device and ailier being beaded can be quickly removed. The de vice may also be used equally as well for einbossine' or beading articles other than lamp shad s.

Having thus described my invention,

it is may be made in the same without departing from the spirit of my invention; hence I do not Wish to be understood as limiting myself to the exact form, construction, arrangement and combination of parts herein shown and described, or uses mentioned.

lhat I claim` as new and desire to secure by Letters Patent is 1.
