MARTIN VAN BUREN GRUSI-I, OF BALDWIN, INDIANA.

CLOCK-SHELF.

SPECIFICATION forming part of Letters Patent No. 600,528, dated March 15, 1898. Application filed June 3, 1897. Serial No. 639,315. (No model.)

To ctZZ whom it may concern.-

Be it known that I, MARTIN VAN BUREN GRUSH, of Baldwin, in the county of Allen and State of Indiana, have invented certain new and useful Improvements in Clock- Shelves; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertain's to make and use the same.

This invention relates to leveling devices for leveling mantelpieces or shelves, and is especially designed to be used in connection with shelves or mantels upon which clocks or timepieces are kept.

The object of the invention is to produce a simple and cheap device of the character mentioned by which the shelf or mantelpiece can be accurately and quickly leveled in either direction.

I am enabled to accomplish the objects of my invention by the means illustrated in the accompanying drawings, in which- Figure 1 represents a perspective view of the device attached to a wall-plate and shelf and showing the revoluble spirit-level upon said shelf. Fig. 2 represents a transverse section of the same, showing the means for attaching the wall-plate to the wall and means for securing the shelf to the set-screw.

Referring to the drawings, the numeral 1 indicates a wall-plate, which is preferably constructed of wood and provided near its upper and lower ends with metallic eyes 2 for the reception of screws, by which the plate is securely fastened to the wall. The lower eye 2 is slightly elongated horizontally.

The numeral 3 indicates two hinges, which have one leaf secured to the upper wall-plate and the other to the under side of the shelf or mantelpiece 4.

The numeral 5 indicates an arm, which is bent downwardly at its rear end and flattened to form a plate 6, which is firmly secured to the wall-plate by means of screws. The arm 5 extends forward, preferably, as far as the forward edge of the mantelpiece, where it is provided with an enlargement 7, which is provided at its center with an internally-screwthreaded opening 8, through which passes an externally-screw-threaded key or set-screw 9, which extends a short distance above said enlargement and is provided at its end with an upset portion or head 10, which is adapted to enter the recess 11, formed in the plate 12, which is secured tothe under side of the mantelpiece,preferablyat or nearits forward edge.

The plate 12 is preferably constructed in two pieces, recessed as described, forming when put together a circular opening provided with shoulders, upon which rests the upper end of the key 9.

Seated in the circular opening or recess in the upper side of the mantelpiece or shelf is a spirit-level 13, which is capable of being turned in any direction, so that the said shelf or mantelpiece can be leveled in either direction of its length or width;

To level the shelf lengthwise, the screw in the lower eye 2 is loosened, and the shelf is then movable upon the upper screw, serving as a pivot, and when the shelf is level, as indicated by the spirit-level, the lower screw is tightened and the shelf thereby secured in its proper position.

It will be obvious that when the set-screw 9 is turned in one direction the mantel or shelf Will be caused to rock upwardly upon its hinges, and when turned in the opposite direction said shelf will rock downwardly to any desired angle of inclination relative to the wall-plate.

When it is desired to level the shelf in the direction of its width, the tube of the spiritlevel will occupy the position shown in full lines in Fig. 1 of the drawings, and when it is desired to level the shelf in the direction of its length the said spirit-level will be turned to the position shown in dotted lines in said figure.

Any number of arms and set-screws and plates for receiving the upper end of said screws can be placed beneath the shelf, and the same in practice will be made in ornamental designs and serve as a support for maintaining the shelf in a level position.

I do not desire to be understood as limiting myself to the precise construction shown in the drawings, and many modifications involving mechanical skill may be made in my de- Vice without departing from the spirit thereof.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is

turning. said adjusting-screw; all arranged substantially as described and shown.

2. In an adjustable clock-shelf device,.the

combination with a wall-plate of a shelf hinged thereto; a plate 12 secured to the under side of said shelf provided with a recess 11; afor-- wardly-extending arm secured to the wallplate, having at its outer end a screw-threaded aperture; an adjusting-screw passing through the screw-threaded aperture of the outer end of said arm and having at its upper end a head adapted to revolubly engage in the recess 11, whereby the shelf can be raised or lowered by turning said adjusting-screw; a revoluble spirit-level seated in the shelf whereby the inclination of the shelf can be determined; all arranged substantially as described and shown.

3. In an adjustable shelf device, the combination with a wall-plate having eyelets 2, 2, of a shelf hinged thereto; a plate 12 secured to the under side of said shelf provided with a recess 11; a forwardly-extending arm secured to the wall-plate having at its outer end a screw-threaded aperture; an adjustingscrew passing through the screwthreaded aperture of the said arm and having at its upper end a head .10 adapted to revolubly engageinthe recess 11 whereby the shelf can be raised or lowered by turning said adjusting-screw; a revoluble spirit-level seated in the shelf whereby the inclination of the shelf can be determined and all arranged substantially as described and shown.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

MARTIN VAN BUREN GRUSH.
