EDWARD T. PRINDLE,

OF AURORA, ILLINOIS.

DOOR-HANGER.

SPECIFICATION forming part of Letters Patent No.423,952, dated March 25, 1890.

Application filed November 6, 1889. Serial No. 329,407. (No model.)

To all whom it may concern:

Be it known that I, EDWARD T. PRINDLE, of Aurora, in the county of Kane and State of Illinois, have invented certain new and useful Improvements in Door-Hangers; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereomwhich form a part of this specifica- 101].

The present invention is a further improvement on the door-hanger patented to me 00- tober 12, 1886, No. 350,638; and it relates to that portion of its construction by means of which the door can be raised or lowered at will through the agency of an adjusting collar-screw, all of which will be made clear, as hereinafter described.

In the drawings, Figure 1 shows the top corner of that end of a sliding door which in a dwelhng would be in sight, and with that part of a hanger in which myimprovement consists applied thereto. Fig. 2 shows such part of the hanger detached from the door-top; Fig. 3, a plan, the screw being removed.

By my present improvement I dispense altogether with the vertical end plate or plates which are screwed upon the top portion of the vertical edge of the door, and which plates have an opening through which the head of the adjusting collar-screw protrudes, and instead I so construct the hangerplate of the hanger as that it shall receive the collar of the collar-screw and permit it to be turned in either direction to raise or lower the door, but without itself advancing or receding.

A represents that upper cornerof a sliding door to which the hanger is attached, and a the vertical edge of the door to which in my patent above named the end plate above referred to was secured. In the plate I) of the hanger O, I cast an opening d, havinga shape, as shown, adapted to receive the collar 6 of the collar-screw F, this screw being similar to those in my above-named patent but the opening should be such relatively to the collar, or the collar of the screw so made relatively to this opening or slot, that while the screw may be freely turned with its collar,

yet the collar shall have no endwise play in the slot, because this play would permit a lost motion. By my construction there is no lost motion, any more than in my abovenamed patent, and upon the slightest turning of the screw in either direction the door responds accordingly, and not onlyinstantly, but quietlyavithoutany rattling, jarring, or poundingso objectionable in many door-hangers. This slot or opening (I is transverse of the plate and located just at the front of the spur or projection g, through which the shank of the screw passes. The head of the screw should project outward far enough to receive a screw-driver properly.

As distinguished from inosthangers in the market, and whose adj HStlDg-SCTGW has no 001- lar, (but simply a head, and hence called capscrews,) my construction, like that in my patent above named, acts positively to move the door whether the screw be turned to the right to raise the door or to the left to lower it, while when a cap-screw is used, although it will raise the door when turned to the right, yet when turned to the left its unthreaded shank will back out of its nut, and in order to bring the door down to its desired'adjustment it must be jarred, shaken, or pounded.

It will be observed that by my present improvement I do not require two pieces-one on each side of the collar-to prevent endwise movement of the adj usting-screw, but that a single piece-namely, the base-plate b-alone does the duty of two, and therefore at a greatlyreduced cost to the manufacturer and to the public. Not only do I thus dispense with the end plates, as above stated, but the end of the door at its top corner needs no cutting away to receive the same, and only requires a small cavity (which a gimlet could make) in the wood at the extreme top corner sufficient to house the head of the screw.

While the construction set forth in my Patent No. 350,638 is all that could be desired as to efficiency in use, yet it is found desirable in houses of more economical construction, while retaining in the hangers the leading principles of that invention, to simplify them while still preserving all their efficiency. By my present invention I dispense not only with two bronze vertical plates for the top of the visible edge of two doors, but also with two iron vertical plates for the concealed edge of the doors; and as the bronze ones have to be highly finished and are costly, and itrequires a skilled workman to fit any of such plates into the edge of a door, it will be readily seen that for cheap houses a great saving in the cost of hangers may be effected by my im provement, besides having fewer parts, and also affording a hanger which can easily be applied Without a very skilled mechanic.

I claim 1. A top plate for door-hangers, having; therein a transverse slot (1 at the front of its tubular part C, substantially as set forth.

2. In combination with the top plate having the transverse slot d therein, a screw having a collar near its outer end adapted to lodge in such slot.
