HAND ROLLER;

Application filed January is, 922. Serial No. 530,064..

To aZZ whom it may concern; j

Be it known that T, RA PH 13. Brno, a citizen of the United States, residing at 220 Lake Shore Boulevard, ,Oaliland, in the county of Alameda and State. of California have invented certain new anduseful Im-.

- provements in Hand Rollers, of which the following is a specification. p,

This invention relates to rollers, and n particular to pressure-rollers; of that type by which the application of the thereto, is by meansof the hand. o

The objects of the invention are, to propressure duce a hand-roller .of this type as. a new,

article of manufacture, so designed andcon structed as to be light in. weight. and yet give maximum service with minimum handpressure effort; toprovide a handle of substantial form and grip and symmetrically.

positioned with respect to the device so as to eliminate the tiresome muscular strains of the wrist, so commonly encountered while using existing rollers; also to form the roller with tapering ends to eliminate the edgelines of the roller on the article or surface rolled, and also to provide the device with ball bearings for ease of operation and minimum upkeep.

One of the major arts in which my'invention may be employed is that of photography. for the purpose of rolling prints;

that is, when the prints are removed from the bath they are laid upon a hard smooth special surface and judiciously rolled to remove the water and air bubbles therefrom. Prints rolled in this manner whenremoved from the hard surface have a high-grade uniform finish. There are many other efficient uses in other arts for my improved.

. Fig. 4 a view partly in section of a modified form of roller.

1 in Fig. -1 represents the center from which two pairs of arms 2, 2 and 3, 3 re diate, forming frame of spider-like construction. The. arms 2, 2 lie in a plane and have their ends turned downwards, shown clearly in Fig. 2, terminating in bosses 4 for the support of a shaft 5. The arms'i-l, 3 lie also in a plane, which latter. may be at rightangles tothe former plane; these arms are turned upwards, their extremities LGXIHLIIQis ing in a cross-member 6, forming with said member a loopedhandle. The member 6 iatrs is may be hollow and enlarged in'the center gradually tapering towards its ends as shown. afford ng a strong substantial grip.

The wide loop of the handle allows the fingers to pass through and be closed about the cross-member in any manner best suited to the opera-tor. j j

j The ,frame may be of unit construction, a single casting of aluminum or other preferred material. The frame carries the shaft 5 which may be a single rod or two shorter pieces, an end of each being sup- 1 ported in tne bosses 4 by the screw 5 or any other well known manner.

7 is a roller rod-like in form, preferably made of hard wood and is carried by the.

shaft The roller is formed with rounded tapering ends 8, to eliminate all edge-lines of the ends of the roller on the wet prints when rolling it over the prints on a hard surface.

conforming to the longitudinal thereof. The roller may also be grooved as at 10, and the sleeve provided with a tongue to engage the groove to prevent lateraldisplacement of the sleeve in operation.

In Fig. 2 the end faces of the roller are shown recessed, engaging ordinary ball bearings 11 pressed or otherwise secured therein for the purpose of minimizing friction.

In the modification of the roller shown in Fig. 4:, the longitudinal bore is of the same diameter as the counterbore of Fig. 2 for the ball bearings 11, and the latter bearings may be spaced apart by the tubular spacers 12, which may snugly fit within the bore and be of any suitable material. This roller is of similar shape to that of the shorter The roller may be covered by a rubber tube or sleeve 9, snugly fitting it and j roller of Fig.2 and similarly covered with rubber.

I am aware'that prior to my ln'vention,

many other types of rollers were employed.

in the art of photography, but longperiods of usewith these other types have led me to perfect one "with the idea in view-to elimi nate the Wrist strains already referred to" and to remove the possibility of injury to the prints in rolling, therefore, I do not broadly claim a new pressure-roller, but

only to the extent that I have benefited the" arts.

What I claim as neWand' desireto seo'iire i in combination, a framing and'a roller, said framing composed of two pairs of arms cast lntegral and radiating from acommon center and a shaft, one' pair of saidarms forming a handle, and the other pair form:

ing'a Wide-mouthed gapv for the reception o'fsaid roller, and the said shaift'a'dapted to carry the roller and be supported in the'ex treinitiesofthe arms forming the said gap,

the surface of the roller being provided with tapered ends adapted to el'iininatelthe edge' lines of the roller when in operation.
