the art to which it appertains to make and use the same. 7

My invention relates to adjustable rollers for doors, windows, or the like, and has for its object to provide a roller for the abovenamed purposes which will bring the frames of the doors and windows and the casings up close together and parallel with each other without removing or resetting the roller.

With this object in view I have constructed a roller which is cheap to manufacture, easy of operation, and, above all, practical and efficient, the points of novelty of which will hereinafter be fully described, and more particularly set forth in the appended claims. Referring to the accompanying drawings,

Figure 1 is a front view of my improved roller in an operative position. Fig. 2 is a sectional view of the same, taken on the lines X X of Fig. 1. 3o roller.

The same letters of reference indicate like parts throughout the several figures, in

which- A is the main plate,substantially semicircular in form and provided with the screw-holes a near the periphery thereof, quadrangular openings or, and an eccentric circular opening a B is the rear plate, substantially semicircular in form, but much smaller than the main.

with a quadrangular opening 0, said lever be ing T-shaped in form, except that the top 0 is curved on an are described by a radius extending from the quadrangular opening 0.

D is the eccentric-pin,havin g two eccentricjournals d and (1 said journal cl having its end flattened to fit the opening 0 in the lever O, the journal d revolving in the eccentric opening a in the main plate A, and the journal d revolving in the eccentric opening b in the rear plate B.

E is the roller designed to revolve on the pin D and having a smooth periphery or tread.

F is a frame, G the casing, and g a groove therein.

The arms I) of the rear plate B are bent at right angles to said plate and the nibs b register with the quadrangular openings at of the main plate A. They are then fastened or clenched in any suitable manner.

Having thus specifically set forth the several parts of my invention, its operation is as follows: When the roller is set into the frame, as shown in Fig. 1, the guide and adjusting- 7o lever is turned down into the groove g, as shown in Figs. 1 and 2, thus preventing the frame F from lateral movement. Said adj usting-lever being securely attached to the eccentric journal 6. of the pin D turns said pin D up or down according as the lever is turned Consequently if it is desired to lower the roller in order to raise the frame F the adjusting-leverC is turned to the right until the roller E is lowered sufficiently. The screw f is then screwed in until its head holds the top 0 of the adjusting-lever 0, thus holding said lever and roller securely at the desired adjustment. If, on the other hand, it

is desired to raise the r0ller,and consequently lower the frame the adjusting-lever is turned in the opposite direction and secured as described.

I do not wish to be understood as limiting myself to the exact construction herein set forth,as various slight changes might be made therein by those skilled in the art; but I con- 'sider myself entitled to all such changes and inodifications Which fall within the limit and scope of my invention. .4

What I claim asnew, and desire to secure by Letters Patent of the United States, is

1. In an adjustable roller, the combination of the roller; the eccentric-pin, and the adguide substantially as shown and described. I

justing lever and 2. In an adjustable roller, the combination with the main and rear plates thereof, of the eccentric-pin journaled therein, the roller having a smooth periphery o'r tread and journaled on said eccentric-pin, and the adjusting-lever and guide secured to said eccentricpin,'substantia11y as shown and described.

In testimony whereof I affix my signature in presence of two witnesses. i r EDWARD JOHN GULICK.
