Specification of Letters Patent. Patented Dec. 16, 1919;"

Application filed October 1, 1917. Serial No. 194,105.

To all whom it may concern:

Be it known that we, WALTER G. SIMP- son andJAMEs A. STEWART, both citizens of the United States, and residents of the city of Oakland, county of Alameda, and State of California, have made a new and useful inventionto wit, Improvements in Sash-Adjusters; and we do hereby declare the following to be a full, clear, concise, and exact description of the same.

The present invention contemplates a sash adjuster that is neat in appearance, compact in structure, adapted to be easily positioned and operatable in an apparent manner.

Another object of the invention is the re duction of the number of parts to lessen the cost of production.

A. further object is to frictionally control the position of the sash as well as provide means of adjustment in regulating the resistance in adapting the adjuster to any side swinging or casement sash.

In this specification and the annexed drawings we illustrate the invention in the form we consider to be the best; but it is to be understood that we do not limit ourselves to such form because the said invention may be embodied in other forms, and it is also to be understood that in and by the claims following the description we desire to cover the invention in whatever form it may be embodied.

In the accompanying one sheet of drawings:

Figure 1 is afront elevation of a window showing the sash adjuster applied thereto.

Fig. 2 is an enlarged sectional view of the interior construction of the sash adjuster.

In the first figure of the drawing the win dow frame illustrated, consists of the stool 1, side j amb 2, with the window sash 3 hinged thereto in the usual manner. The sash adjuster is mounted with one end secured to w the stool 1 by screws 6 and the opposite end 7 fastened to the lower rail 8 of the sash 3.

In detail the sash adjuster consists of a tubular member 9, flattened at one end and having the bracket 6' pivotally mounted thereon. The sliding rod member 11 telescopes within the tubular member 9 and is pivotally secured to the bracket 12 fastened to the rail 8 by screws 14c. The end 16 of the member 9 is slotted and provided with the rolled threads 17. The rolled threads are used in preference to the ordinary cut thread because it permitslighter tubing ma;

terial to be-used, reduces the possibilityof' the threaded portion shearing off, and does away with the necessity of having an extra abutment, within the tube 9 to act as a bumper for the head 19, formed on the end 20 of the sliding rod 11. v

The rod 11 moves freely within the tube 9 and is prevented from escaping from said tube by the internal projection of the rolled threads 17. The knurled clamp 21 threaded internally at 22 and slightly tapered, screws onto the tubular member 9. Rotation of the clamp 21 forward or rearward on the slotted end 16 either reduces or enlarges the internal diameter of said end 16, sothat the rod 11, held within the member 9, is controlled frictionally by the clamping action exerted on it by the knurled clamp 21.

The device is assembled as follows. The tubular member 9 is threaded and slotted as at 17. The rod 11 having one end 20 upset, is slidably retained within the member 9 by the end 20 bumping against internal projection of the threaded portion 17. To prevent the rod 11 from escaping the opposite end of the tube'9 is flattened and ivotally secured to the. elevated bracket 6.

The knurled clamp 21 is screwed onto the slotted end 17 of the member 9 and is retained on the rod 11 by the bracket 7 pivotally secured on the end thereof.

The adjuster can be applied to any casement sash and the adjustment as well as the variable resistances, encountered in different styles of sashes are overcome and controlled by the knurled clamp 20 exerting its pressure on the slotted, threaded end 17 which in turn frictionally engages with the sliding rod 11.

An adjuster of this construction will hold its frictional adjustment avoiding the necessity of releasing the friction each time that the sash is moved, hence the adjuster can be placed at the top of the sash if desired.

Having thus described our invention, what we claim and desire to secure by Letters Patent is: i

1. A sash adjuster including a tubular member having one end thereof slotted and threaded with a rolled thread; a rod slidable within said tubular member; means on saidrod for limiting the extensible movement thereof by engagement with the internally rolled thread; a clamping nut adapted to en gage the threaded end of the tubular memher and frictionally control the movement of said rod and fastening means on the ends of said tubular member and rod.

2. A sash adjuster including a tubular member having one end thereof slotted and threaded with a'rolled thread; a rod slidably mounted Within said tubular member; a clamping nut threaded internally and engaging the threaded end of the tubular member for frictionally controlling the movement of said rod; an enlarged end on said rod for engaging the internally rolled threads of the tubular member for limiting the extensible movement thereof and. fastening means on the ends of said tubular memher and said rod.

In testimony whereof We have hereunto set our hands at Oakland, California, this 18th day of September, 1917.
