NELSON H. BRAY,- OF BERKELEY, CALIFORNIA.

ADJ'USTER. FOR SASHES, DOORS, AND THE LIKE.

Application filed January 23, 1922. Serial No. 531,047.

To all whom t may concern:

Be it known that I, NELSON I-I. BRAY, a citizen of the United States, and a resident of the city of Berkeley, county of Alameda, State of California, have made a new` and useful invention-to wit, Improvements in Adjusters for Sashes, Doors, and the like; and I do hereby declare the following to be a full, clear, concise, and exact description of the same.

The invention relates particularly to a sash adjuster of the friction type.

Among the objects of the invention are to provide means for locking movable objects such as sashes, doors and the like hinged or pivoted to 'a movable object in the desired adjustment against displacement by wind pressure or otherwise by frictional resistance, suflicient vfor the purpose but adapted to be overcome by manual operation of the apparatus connecting the movable to the immovable objects. Other objects and advantages willappear as this description progresses.

In this specification and the annexed drawing, the invention is illustrated in the form considered to be the best but it is to be understood that the invention is not limited to such form because it may be embodied in other forms, and it is also to be understood that in and by the claims following theJ description it is -desired to cover the invention in whatever form it may be embodied.

In the accompanying one sheet of drawings.

Fig. 1 is a view diagrammatically illustrating the application of the adjuster arm to a window sash and casing.

Fig. 2 is a vertical cross section through Figure 1 on the line 2-2.

Fig. 3 is a lateral cross section through Fig. 1 on the line 3-3- Fig. 4 is an end view of the adjuster.

Fig. 5 is a perspective view of the adjuster.

Fig. 6 is a section taken through Fig. 1 on the line 6-6.

In detail the construction illustrated in the drawings includes a bracket 1 provided with a passage 2 therethrough, said bracket having a foot-piece 3, with screw holes 4 therethrough, pivotally or rigidly secured to the said bracket. The foot-piece 3 of the bracket 1 is adapted to be secured to a relatively immovable object, such, for instance, as a lintel, jamb or other part of a door or window casing.

A; somewhat modified form or frictional bracket comprising a casing 6, having screw holes Z through the base thereof, is adapted to be secured to a relatively movable object, such, for insta-nce, as a sash, door or the like. A pair ofspaced finger grips or arms 8 and 9A are adapted t0 be secured within and to the base of the casing 6 and the opposite ends of said arms, to project through openings provided in the upper face of the said casing 6.

A pair of shafts or arms 11 and 12 of unequal lengths and pivoted together at 13 are adapted to be arranged between and connecting the respective brackets 1 and 6, the shorter shaft 12 being slidably retained in the passage 2in the bracket 1 and the longer shaft 11 bring slidably retained in a transverse opening 14 provided in the casing 6. The opening 14 in the casing 6 is in substantial alignment with elongated holes 15 provided in the pivoted arms 8 and 9, whereby when sai-d arms are placed in substantially a parallel position relative to each other, the shaft 11 may be` moved freely through the opening 14 in the frame 6 and openings 15 in the arms 8 and 9. The shaft 11 is maintained relatively immovable and frictionally retained within casing 6 by placing the arms 8 and 9 out of parallel, whereby the end of slots 15 will engage the shaft 11 and thus create a friction at the points of contact. A spring 16 is interposed between the arms 8 and 9 and around the shaft 11 to normally maintain the said arms 8 and 9 out of parallel and to thus frictionally engage the shaft 11.

The shaft 12 is held within the passage provided in the bracket 1 by a set screw 5 whereby the position 0f the said shaft 12 relative to the bracket may be adjusted or changed at will. A set screw is used in the bracket 1 to contact with the shaft 12 as under ordinary operating conditions the shaft 12 will not be moved after it has been properly located. For instance, the footpiece 3 of the bracket 1 would be secured to a lintel, j amb or other part 2O of a window or door casing, whereby the pivotal point 13 of the shafts 11 and 12 would lie opposite the joint or hinge point of the sash or door 22 secured to the said jambs or kSO casing 20. The frictional adjuster casing 6 would be located on the rails of the sash or door at a predetermined point where it would readily engage the shaft 11. Should by any chance, the pivotal axis vof the connected shafts 11 and 12 become disarranged relative to the hinge point or' the sash and easing, the proper relocation may be made by unloosening the set screw 5, releasing the frictional grip exerted .in the casing 6 and moving the short shaft 12 to the desired position and then fixing it permanently in position by tightening on the set screw 5.

The brackets 1 and 6 are speciiically designated for identification only and may be varied to suit the nature of their application.

ln the present instance the bracket 1 is screwed to the lintel, jamb or other part 2U, (see F ig. l) of the window or door casing, by screws passing through the holes 4L. The bracket 6 is similarly attached by screwing through the holes 7 engaging the side rail 21 or other part or the sash or door The adjuster is atached to give the desired opening and closing to the sash or door 22, which is conventionally pivoted or hinged in the frame 20. The friction exerted between the moving arm and adjuster bracket 6 frictionally holds the movable sash or door 22 in any position at which it may be placed by the operator. Movement of the sash 22 acting against the friction adjuster 6 is impossible for the cooperating stood as limiting it thereto, as it is obviously adaptable for attachment to the various forms oi' lids oi' trunks, chests and the like, or wherever a rictional adjuster is ap` plicable.

Having thus described my invention, what I claim and desire to secure by Letters Patent is: j

1. A :trictional adjuster including a pair oit' pivotally connected arms; adjustable irictional means for engaging' an end of one of said arms and a relatively immovable frictional means for engaging the other arm.

2. A frictional adjuster including a pair of pivotally connected arms and adjustable iriction means adapted to be slidably secured to one of said arms and friction-al means adapted to be arranged in a relatively' stationary position on said other arm.

In testimony whereof, I have hereunto set my hand at San Francisco, California, this 81st day or' December, 1921.

NELSON H. BRAY. In presence of- LiNootN V. JOHNSON.
