STAY-ROLLER.

Specification of Letters Patent.

Patented March 10, 1908.

Application filed November 18, 1907. Serial No. 402,686.

T 0 all whom it may concern:

Be it known that I, FRANKSHlMERDA, a citizen of the United States, residing at Swanton, in the county of Saline and State of Nebraska, have invented certain new and useful Improvements in Stay-Rollers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled inthe art to which it appertains to make and use the same.

My invention relates to new and useful improvements in stay rollers and more particularly to that class adapted to be used in connection with sliding doors.

My object is to provide a cheap and durable means for engaging the lower end of a sliding door and prevent the same from swinging outwardly from the wall of the building as the door is moved back and forth.

A further object is to provide a bracket for supporting the stay roller which is made from one continuous piece of metal, and a still further object is to provide means for protecting the pivot pin for the roller and prevent the same from becoming accidentally broken by a blow from the door.

Other objects and advantages will be hereinafter referred to and more particularly pointed out in the claims.

In the accompanying drawings which are made a part of this application, Figure 1 is a side elevation of a portion of a structure showing my improved stay roller operatively a passage 5.

secured thereto. Fig. 2 is anelevation of a portion of the structure showing the door and stay roller in edge elevation. Fig. 3 is a front elevation on an enlarged scale of the stay roller and bracket therefor. Fig. 4 is an elevation thereof, and, Fig. 5 is a plan view of the blank employed for forming the supporting bracket for the stay roller before the same is bent into shape to receive the roller.

Referring to the drawings in which similar reference numerals designate corresponding parts throughout the several views, 1 indicates the wall of a building to the side of which is secured a trackway 2, said trackway being designed to support a door 3 which is movably mounted upon the trackway by any suitable form of supporting carriage 4 so that said door may be moved longitudinally along the side of the building to open or close In doors of this class it is customary to leave the lower end of the door free and in order to prevent the door from swinging outwardly from the wall of the building I provide my improved form of stay roller 6 which is carried in a bracket 7 said bracket being offset at a point in its height to dispose the upper portion thereof a distance from the wall of the building while the lower portion of the bracket is provided with openings 8 to receive screws or the like 9 and by which means the bracket is secured to the wall 1. The roller 6 is held in position upon the bracket by means of cars 10 which are formed by severing the upper portion of the bracket and directing the severed portions at right angles to the face of the bracket.

After the ears 10 have been formed at right angles to the face of the bracket, the corners of the upper ear are bent downwardly to form stays 11 while the corners of the lower ear are bent upwardly to form stays 12 thereby partially incasing the roller 6 and protecting the same from a direct blow as when the edge of the door is moved into engagement therewith.

The roller 6 is rotatably mounted between the ears 10 by directing a pin 13 longitudinally through the roller 6 and through the ears 10 and it will be seen that by arranging the stays 11 and 12 as described, said stays will rest in juxtaposition to the outer periphery of the stay roller and prevent undue strain or pressure on the pin 13.

The bracket 7 and ears thereon are formed of a single piece of metal and the manner of constructing the ears is best shown in Fig. 5 of the drawings and in making the ears, the body of the bracket 7 is vertically severed as shown by full lines at 14 and the portion of the metal between the severed lines is then separated at the line 15 after which the parts thus formed are bent outwardly in opposite directions and at right angles to the face of the bracket and the ears 10 formed. Stays 11 and 12 are then formed thereon by bending the corners of the ears 10 at the points indicated by dotted lines 16 and 17, respectively.

4 The roller is preferably disposed in line with the lower end of the door so that the outer face of the door will rest against the stay roller 6 when said door is moved back and forth on the trackway 2 andshoul'd the door be moved beyond the roller 6 in either direction, the stays 11 and 12 will prevent the edge of the door from strikin the roller a direct blow and thus prevent t e jar coincident thereto from extending to the in 13, which might result in the breaking of t e pin.

It will now be seen that I have provided a very cheap and economical means for staying the lower end of a sliding door and preventing the same from swinging away from the Wall of a building. It Will further be seen that by forming the supporting bracket for the stay roller of one piece of metal and providing ears thereon as shown, the bracket Will be materially strengthened and the probability of breaking the pivot pin of the roller reduced to a minimum.

What I claim is:

A device of the class described comprising
