lPICTURE-HANGER.

SPECIFICATION forming part of Letters Patent No. 522,510, dated July 1894- Application led November 1,1893. serai 110.489,691. (No mien To al? whom it may concern: v

13e 1t known that I, Louis CHURCH, a citi- .zen of the United States, residing in Buffalo, 1n the'county of Erie and State of New York, have invented certain new and useful Iinprovements in Picture-Hangers, of which the following is a specification.

My invention relates to certain improvements in picture hangers whereby a single suspending rod is combined with adjusting devices for adjusting the picture frame either uphdown, or sdewise and also for adjusting itsinclination, all of which will be fully and clearly hereinafter described and claimed reference being had to the accompanying drawings, in which- Figure 1, is a side elevation, showing the device connected with a picturey frame. Fig.

- 2, represents a back View of the same, also showing 1t attached to a picture frame. Fig.

3, 1s an enlarged detached .side elevation of the picture frame adjusting device, showing only a portion of the suspending rod, the arm for carrying the toothed cams being in section, o n line, a, oi, Fig. 4. Fig. 4, represents a rear View of the arm for carrying the toothed cams.

Referring to the drawings in detail, 1, represents the substantially vertical suspending rod. It is preferably made round or nearly so 1n cross section, of brass or iron, but any other suitable material may be used. At the back of the suspending rod 1, is a series of notches or teeth, 2, which extend nearly the Whole length of said rod. The top of the suspending rod is provided with two hooks, 3 and 4, the hook 3, being used to connect it 'l to a nail when required, the hook 4, being adapted to catch over a molding, 5, substantially as shown in Fig. 1. The hook, 3, if req uired may be made in the form of a loop or ring adapted to be easily placed over a nail. At the lower end of the suspending rod is another hook portion, 6, the object of which is to prevent the rod from being pulled en` tirely out from its holding device. It will be noticed that the hook, 4, is placed substantially at right ang-les to the hook, 3, thereby adapting it to catch over a molding as hereinbefore mentioned. Y

7, represents a nearly semicircular supporting bar. Itis provided with a base or attach-i provided with a hook, 11, which catches overv and holds the suspending cord, 12. This cord, 12,--is made of wire or other Well knownV ina terial adapted for the purpose, it is attached to thevf rame in' the usual'way by screw eyes, 13.

yOn the inner side of the curved supporting bar7, is ay series of notches or teeth, 14, the object of which will appear farther on. toothed cam supporting arm 15, is slotted at each end at 15, and 15e. Inthe end 15, is pivotedeccentrically by a pin16, a ytoothed cam, 17, it is provided with a thumb piece, 18, by which it is turned on its pivot, 16. Between'the periphery of the cam and end of the slot at 15a, is an opening 19, in which the curved bar, 7, is placed so that the teeth, 20, in the cam, 17, engage with the teeth, 14, in the curved bar, 7, and are kept in engagementjby means of a spring, 21. The cam is easily disengaged by pressing on the thumb piece, 18, so as to turn the cam in the direction of the arrow, o, Fig. 3. From the above description it will be seen that by thus disengaging the cam, the arm, 15, can be moved along the curved bar, 7, in either direction, and that on releasing the thumb piece, the

spring will immediately act and bring the` teeth into close engagement so that the arm, 15, cannot be moved downward or in thedirection of the arrow w, (see Fig. 1,) and that the greater the force' brought against it in that direction, the stronger it will be held at `the point towhich it may have been adj usted.

At the opposite end of the arm, 15,"or at the end 15e, is pivoted eccenti'ically by a pin, 22, another toothed cam wheel, 23. This cam wheel is also provided with a thumb piece, 24, by which it may be turned on its pivot. Between the teeth, 25, of this cam wheel and the end of the slot or opening at 15e, is a space, 26, large enough to allow 'the vertical rod, 1, to slide between them when the cam is in position to permit' it.

To keep the cam, 23, in its normal position The" roo I or its teeth in contact With the teeth, 2, (see Fig. 3,) a spring, 27, is used which holds it back in the direction of the arrow, To release the cam so that the rod, 1, may be slipped easily up or down, all that is necessary to do :is to press on the thumb piece, 24, in the direction of the arrow, y, and the 1noment the thumb piece is released, the spring acts and the can holds the arm, l5, rigidly at the point to which it may have been adjusted.

From the above description it will be seen that a picture frame may be easily adjusted up or down by means of the toothed cam, 23, and the toothed rod, l. The inclination of the frame may be adjusted by means of the curved bar, 7, and its connecting cam Wheel, or the frame may be adjusted laterally by means of the slot, 9, and the holding screws.

I claim as my inventionl. In a picture frame hanger, the combina tion with a single vertical suspending rod provided With a series of teeth extending down one side,of a cam supporting arm, having one end secured to an attachment adapted to be fastened to a frame and its opposite end provided with -a toothed cam Wheel pivoted eccentrically to the supporting arm and adapted to engage with the teeth in the vertical supporting rod, a spring` for holding the cam Wheel in engagement therewith and a thumb piece by which it may be disengaged therefrom, whereby the frame may be adjusted vertically up or down and firmly secured at the point adjusted, substantially as described.-

2. In a picture frame hanger, the combination of a single nearly vertical suspending rod having a series of teeth extending down one side, a cam supporting arm having at one end a toothed cam wheel pivoted eccentri cally thereto, a curved bar adapted to be secured to a frame and having teeth on its 1nner side for engaging with the teeth in the calnwheel, a spring for holding the cam vvheel in engagement and a thumb piece for dlsengaging it, and means for holding the opposite end of the cam supporting arm to the vert1- cal suspending rod, whereby the inclination of a frame to which the device may be attached can be adjusted and secured, substantially as described.

3. In a picture frame hanger, the combination of a single nearly vertical suspending rod having a series of teeth extending down one side, acarn supporting arm having at both ends a toothed cam wheel pivoted eccentri cally thereto, each wheel having a spring for keeping it in engagement and a thumb piece for disengaging it, a curved bar having a slotted base by which it is adapted to be at tached to a frame so as to have a lateral ad' justment, a series of teeth on the inner side of said curved bar for engaging with the teeth in the pivoted cam Wheel at one end of the cani Wheel supporting arm, the vertical supporting bar teeth engaging with the teeth in the cam wheel at the opposite end ot the cam wheel supporting arm, substantially as and for the purposes described.
