SUPPORT FOR EDGEWISE-MOVABLE DOORS.

Specification of Letters Patent.

Patented Sept. 1, 1908.

Application filed March 21, 1908. Serial No. 422,504.

To all whom it may concern:

Be it known that 1, JAMES JoYoE, a subject of the King of Great Britain, residing in the city of Toronto, in the county of York, Province of Ontario, in the Dominion of Canada, have invented certain new and useful Improvements in Supports for Edgewise- Movable Doors, of which the following is a specification.

The invention relates to improvements in supports for sliding doors as described in the present specification and illustrated in the accompanying drawings that form part of the same.

The invention consists essentially in the novel construction and arrangement of parts whereby the door is suspended from a track by a traveling support running on a track and secured to said door and adjustable therein from the side of said door, and whereby the door is checked in its travel by an adjustable stop engaging said hanger.

The objects of the invention are to obtain a perfect balance of the door and consequently insure ease of operation, and to devise a simple and durable support for sliding doors which may be quickly and accurately adjusted without disturbing the easements and will uide the door in its travel and hold it securely from displacement and may be readily placed in position without injury to the door and manufactured at low cost.

In the drawings Figure 1 is a perspective view of my device shown attached to a portion of a door and supported on the running track. Fig. 2 is a vertical sectional view through a door and its surrounding casements showing the arrangement of the su port. Fig. 3 isa pers ectivedetail'of tl ie supporting plate secure to the door. Fig. 4 is an enlarged perspective detail of the stop, partly broken away. Fig. 5 is a perspective etail of the bottom guide to the door.

Like numerals of reference indicate corresponding parts in each fi ure.

Referring to the drawings, 1 is a hanger preferably formed of a strip of metal having er end 2 and an orifice near the extremity 0' said strip and a corresponding orifice arranged directly opposite through which the bolt 3 extends, said bolt being rigidly secured in position by the nut 4. The lower end of the hanger 1 is bent at 5 and twisted so that the lower extremity 6 is turned at right angles to the main portion and centrally arranged in relation to the center line of its hooked upper end.

7 is a grooved wheel journaled between the sides of the hooked portion 2 on the bolt 3.

8 is the track upon which the wheel 7 travels, having a broad flat portion 9 and a U-sha ed portion 10, the upwardly extending e ge of said U-shaped portion engaging the inner peripheral surface of the said wheel. The track 8 is supported on a strip 1 1 secured to the casement surrounding the door and held securely to said strip by the screws 12. This form of track is very rigid and sup orts the weight of the door independent of the holding screws.

13 is a dog pivotally secured to thebolt 14 secured in the hanger 1 at the bend 5, the said dog having alaterally extending lip 15 extending underneath the lower ortion of the rail 8 and a tail portion 16. he weight of the tail ortion 16 retains the lip 15 close to the un erside of the rail and effectually prevents the wheel 7 from jumping-ofi the rail. The lower end 6 of the hanger 1 is threaded on its narrow edges and is provided with a nut 17 turning thereon, said nut having notches 18 in the periphery thereof.

19 is the door having a recess 20 in the top thereof and opening to the side.

21 is a plate ri idly secured to the top of the door 19 and c osing the top of the recess 20 and having a rectangular notch 22 formed in one side thereof and a centrally arranged vertical slot 23 opening from said notch. The lower threaded end 6 of the hanger 1 extends through the slot 23, the walls of which extend downwardly below the under surface of the plate 21 to form an extra support and rest on the upper surface of the nut 17 thus supporting the door from the wheel 7.

24 is a block fitting into and secured in the notch 22 with suitable screws and retaining the hanger securely in position.

It will thus be seen that the flattened end of the hanger very simple manner by removing the plate 25 and turning the nut 17 with a punch or other suitable instrument and this may be done without having to remove or displace any portion of the surrounding casement.

28 is the guiding strip for the lower edge of the door having a raised central portion 29, said raised central portion having a slot 30 formed in the top thereof.

31 is a roller journaled on the pin 32 secured in the sides of the central portion 29 of the guide 28 and extending through the slot 30 so that if the door sags on its support from the to a it will not stick on the lower guide but will roll on the roller 31. In installing sliding doors it is necessary that a stop be provided to limit the movement of the door and prevent it being injured and to relieve the supporting hangers from un-' due strain and in order to accomplish this result I have devised-=a stop to be used particularly in conjunction iwith the form of hanger shown and described and which may be readily adjusted at any time without having to remove any portion of the easement.

33 is a bracket having a. flanged upper end 34 adapted to en age the overhan ing portion 10 of thg trac 8 and an inwardIy turned bottom portlon 35 and a vertical slot 36 in the upright portion.

37- is a clamp having a notched end 38 extending through the slot 36 and sliding therein and having a threaded orifice 39 and an upturned outer end 40 adapted to hook around the underside of the track 8. J

41 is a screw extending from the lower in- V wardly turned portion 35 to the upper in- .wardly turned portion 34 of the bracket 33 and having its threaded portion extending through the threaded orifice 39 in said clamp, said screw-being suitably flanged at the top and rotatably held in said bracket, the lower end extending below said bracket and hav-' ing a suitable slotted head. The bracket 33 is hooked on to the track 8 and the clamp 37 raised to hold said bracket securely in position on the turning of the screw 41 which screw may be turned quitereadily with a screw driver through the slot in the easement in which the door travels. .The lower portion 35' of the bracket 33 is upwardly and inwardly flanged at one .end, the extreme end of the (portion 32 being bentjdownwardly and forme 5 5 with a central tongue portion43.

44 is a spring clip formed of a length of spring wire rigidly secured at its looped end to the portion 35 of the bracket 33 and exte'ndin past the tongue portion 43 and bent nwardly at 45 and flared outwardly at the ends.

46 is a buffer of rubber or other suitable cushion material clamped between the tongue ortion 43 and the lower portion 53 of said racket, the outer end extendingbeyond said bracket and between the outwardly extending'portions of the spring clip 44. The tongue portion 43 is drawn tightly down on the said buffer by a screw 47 extending upwardly through the portion 35 and threaded into the portion 42. On the door being closed the hanger 1 strikes the flared ends of the spring clip 44, spreading them apart thus partly checking its movement. The flat side of the .portion 6 of the hanger then strikes against the buffer 46, and the door brought to rest, the spring clip preventing the hanger from rebounding from the buffer.

The principal features of the present invention are that a quick and accurate adjustment of the door may be made at any time without inconvenience and without having to disturb any portion of the easement surrounding the door. Simplicity and cheapness of construction is also an important consideration.

What I claim as my invention is 1. In a support for edgewise movable doors, the combination with a track, a wheel running thereon, and a hanger supported from said wheel and adjustably secured to the door, of a stop clamped to said rail and having a spring clip engaging said hanger and a buffer secured between the jaws of said clip.
