w. c. SCHULTZ PLATE WHIRLER Filed Oct. 12 1925 INVENTOR.

WILLIAM Cl SCl-FJLTZ WILLIAM C. SCHULTZ, OF COLUMBUS, OHIO.

PLATE WHIBLEB.

Application filed ()ctober 12, 1925.

file present invertion relates to an imaroved win ler or we holding im- L a 1 lenient 3Cltlt. especi iiV for use in the P L process of ved plates ior .-.o o. in best results this coating or film must be distributed uniformly over the entire area the woi -ing face of the plate. and dried. to subsequent steps in the process of repro net-ion.

The primary object my invention is the provision of an implement or work holder, known in the trade as a plate whirler, by means of which the film may be evenly distributed over the working face of the plate and dried. In the accomplishment of this object the plate is supported in horizontal position by means of the implement or work holder and the latter is .vhirled, as by hand, over a heating appliance, for the purpose of subjecting the surface coating of the plate to centrifugal action. By the centrifugal action any exmaterial is thrown oil the plate surface,

the coating or film is uniformly distributed over the working tace of the plate, and a coating or film without blemish is provided. he plate is held by the implement, which is suspended from an overhead support, and the implement and plate are adapted to be bodily whirled or spun by hand until the desired results are secured.

i vention consists in certain novel combinations and arrangements of parts involving retaining means and locking means for the plate and suspending means for the rotary implement as will hereinafter be more fully pointed out and claimed.

In the accompanying drawings I have illustrated one complete example of the physical embodiment of my invention wherein the parts are combined and arranged in accordance with the best mode I have thus far devised for the practical application of the principles of my invention.

Figure 1 is an edge view in elevation of the implement embodying my invention.

Serial No. 62,215.

Figure 2 is a face view of the implement showing a p ate in dotted lines retained in the holder and the lock nut inlocked position 1s also shown in dotted lines.

Figure 5 1S a top plan view showingin a diagrammatic manner the relation of the implement to its retained plate.

In the enemphcation of my lnvention l have indicated the plate as P but it will be ly in section and rotary understood that the implement may be utilized to support other manner of "work than the plate illustrated.

In carrying out my invention 1 utilize pair of retaining arms and 2 which are made up of flat metal strips preferably flexible and resilient, and fashioned with retaining slots 3 at their lower free ends. As indicated in Figure 5 the plate is retained between these arms and for best results the diagonally opposite corners of the plate are utilized and inserted in the slots 3 of the arms as a means of support. The respective arms are carried by segmental heads i and 5 each of which is provided with an attaching lug as 6 and the ends of the arms are riveted or bolted to these lugs as indicated in Figure 2. The segmental heads are connected by a pair of links 7 7 and pivot pins 8 passing through the heads and links in order that the arms may be adjusted by spreading or by drawing them together in releasing or in grasping or gripping a plate.

Between the segmental heads is arranged a screw bar or threaded stem 9 with which the opposed segmental heads engage and at its lower end the screw bar is provided with a retaining head 10 to prevent displacement of the segmental heads.

At its upper end the screw bar is fashioned with a bearing head 11, and between the heads of the screw bar a lock nut 12 is arranged for co-action with the two segmental heads. In full lines in the drawing the nut is shown in unlocked position, while in dotted lines Figure 2 the nut is shown screwed down upon the two segmental heads in which position the heads and their arms are held in rigid position with relation to the screw bar for retaining the plate P between the arms.

The rotary implement by means of its Lil head 11 is retained in a non-rotary suspending housing 13 which is fashioned with a suspending eye 1% by means of which it may be detachably hung from an overhead support. The bottom of the housing is formed by a flat open-center screw plug 15 threaded into the housing and between this plug and the bearing head 11 of the threaded stem. or screw bar ball bearings 16 are interposed to insure facile rotary movement of the rotary head. Lubrication for the bearing within the housing is provided by injecting oil through the oil hole 17 in the top of the housing. 7

In use the arms 1 and 2 are manually opened or spread apart for the insertion of the diagonally opposite corners of the plate, it being understood that the lock nut is withdrawn from the segmental heads to permit swinging movement of the arms on the pivots of the heads. After the slotted ends of the arms are engaged with the plate the arms are retained in position until the lock nut is turned to locked position, and in this position the nut firmly holds the segmental heads with their arms and the screw bar in rigid relation in order that the gripped plate with the arms and screw bar may revolve through the bearing head 11 with relation to the sus pending housing. The implement and plate as thus supported are spun or whirled by hand, preferably over a heating appliance, and the spinning or whirling is continued until the coating or film on the plate is evenly distributed and dried. hen desired the plate may be removed by first withdrawing the lock nut, which releases the segmental heads to permit spreading of the arms, and the arms may then be opened to permit the plate to rest upon a suitable support.

It will be understood that the threaded stem or screw bar between the segmental heads or rack segments does not revolve in relation to the rack segments of the arms. The stem or screw bar may be flattened at opposite sides, as indicated by dotted lines at 18' in Figure 3, for co-action with the teeth of the rack segments or segmental heads to prevent relative rotary movement. when the arms are spread apart or drawn together the threaded stem or screw bar is caused to move down or up with relation to the arms, at which time the nut 12 is of course in elevated position as indicated in Figure 2, and out of the way to permit ad justmcnt of the arms.

By suspending the plate at two opposite corners the entire area of the working face of the plate is left substantially free for uniform distribution of the film, and the liquid solution is therefore prevented from collecting in spots on the plate.

The implement may also be used for drying the plates after the picture or image has been applied thereto and the plate developed and washed. in this instance the centrifugal force developed by the whirling motion of the implement and plate throws off the water, leaving a uniformly even surface without streaks, blots or other blemishes.

It will be apparent that the implements may be made up in various standard sizes for use with plates ranging from the smallest size to the largest size.

Having thus fully described my invention what I claim as new and desire to se cure by Letters Patent is 1. The combination in a plate whirler with a non-rotatable housing, of a rotatable stern having bearing head in said housing, a pair of plate retaining arms carried on the stem, co-acting means on the stem and arms for adjustably supporting said arms on the stem, and means for rigidly locking said arms to rotate with the stem.

2. The combination with a non-rotatable support of a rotatable screw bar. a pair of connected, pivoted segmental heads engaging said screw bar, a pair of retaining arms carried by said heads, and a lock nut on said screw bar for rigidly engaging the heads and bar.

3. The combination with a non-rotatable housing, of a screw bar having a. bearing head in said housing, a pair of pivotallv connected segmental heads engaging said screw bar, a pair of slotted retaining arms rigid with said heads, and a locl: nut on the screw bar for rigidly engaging said heads and bar.

In testimony whereof I have afiixed my signature.
