L A ie i l L I all rno'rornrur ROLLER.

Application filed July 24,

To all to how. it may concern Be it known that I, I AYMOND A. Until, a itizen of the United States. residing at Rock: "l nd, in the county of Rock lsland and e of lllinois, have invented certain new .1: nd useful lmpro ven'ients in Photoprint Rollers, o which the following is a specification.

lily invention has reference to photoprint rollers, such as are used for imparting the desired gloss to the prints by who. 1,1; known as the ferrotype process. In this process the prints are laid face downward on the ferrotype board and subjected to a pressure from above, usually by means of a roller operated by hand. If the pressure exerted on the grint is not uniform the print will stick to the board in places, giving a mottled effect to the face thereof. In order to secure the ('lGSll'Qd effect it is necessary to use considerable force, and even then the results are not always satisfactory.

The purpose of my invention to secure a greater uniformity of pressure, in applying the same to the prints, resulti in a more perfect finish thereof. This 1. accomplish by means of a roller, and mmintinptherefor, to which the force is applied largely at both ends, and which. is provided with weight devices to assist in holding the roller closely to its worlz.

In the drawings:

l is a front elevation of the invention.

Fig. 2 is a plan View thereof.

Fig. 3 is a cross-section on the broken line 23-43 of Fig. 2.

l is a handle. adapted to be both hands of the operator, PIOVL.

t, ends with enlargements 2, projected downwardly into bearings 3, in which is gournaled the shaft of a roller of usual construction.

Serial No. 398.746.

The upper faces of the members 2 are pro vided with depressions 5, fitted to receive the outer parts of the palms of the operators hands.

In operation, the handle is grasped by the hands of the operator with the hands hearing downwardly upon the end members 2. while the roller is passed backwards and forwards over the prints, until they receive a sufficient amount of gloss. On account of the members 2 conforming to the shape of the hand, the work is less tiresome, and

there is less danger of the hands becoming calloused. The enlargei'nents also add weight to the tool, and aid in giving a uni form pressure to the print. This uniformity is also aided by the hand pressure at each end of the tool. in case the pressure of one hand is teu'iporarily less than that of the other hand, the weighted member tends to hold that end of the roller to its work. so that there is a requisite amount of contact of the roller at all times.

It is obvious that changes an be made in the form and adaptation of the invention without departing from the spirit thereof.

What I claim and desire to secure, is:

1. A device of the class described, comprising handle provided at its ends with weighted members, and a roller operately connected with said members in parallel relation with said handle.

2. A device of the class described, com-' ends of said handle.

In testimony whereof I afiix my signature.
