ADJUSIING DEVICE.

Application filed July 1S, 1923.

The invention relates to hardware of the kind which is usually employed in building constructions for controlling the movements of transom windows, easement windows, sliding windows, ceiling lights, doors and the like, and has for its object the provision of an improved adjusting device which is characterized in its construction, arrangement and operation by certain hereinafter described features of novelty which peculiarly adapt the device for employment in suoli associations. The adjusting device of the invention is also quite obviously susceptible of employment in connection with vehicles for regulating the positions of carburetor valves, heater valves, radiator shutters and the like.

The adjusting device requires the use of but one hand in effecting an adjustment of the transom window or other closure means with which the device is associated, is readily adapted to the structural peculiarities of any particular mounting surface which might ordinarily tend to conflict with the free operation of such a device, and is not subject to such localized wear as in time might act to impair the eiiieiency of its operation.

l/Vhile the foregoing statements are indicative of the nature of the invention, other objects and advantages not herein specifically referred to will be appreciated upon a full comprehension of the novel features presented in the construction, arrangement and operation of the parts comprising the adjusting device.

In order that the invention may be readily understood, an exemplifying embodiment of the same is set forth in the accompanying drawing and in the following detailed description based thereon. Obviously the invention is susceptible of embodiment in other and varied structural forms without departure from the essence of the invention and without sacrifice of its material advantages; wherefore it is to be understood that the drawing and description are to be considered in an illustrative and not in an unnecessarily limiting sense.

Fig. 1 is a front elevation of a transom window which is equipped on its right-hand side with the adjusting device of the invention;

Fig. 2 is a view corresponding to Fig. 1, but shows a transom window which is Serial No. 652,218.

equipped on its left-hand side with the adjusting device;

Fig. 3 is an enlarged front elevation of the adjusting device when in its locked position;

Fig. i is a vertical section through certain portions of the adjusting device on the line 4 4 of Fig. 3;

Fig. 5 is a horizontal section through the adjusting device on the line 5-#5 of Fig. et.

Fig. 6 is a view which corresponds to Fig. 4:, but shows the adjusting device when in its unlocked position;

Fig. 7 is a horizontal section on the line 7 7 of Fig. 6; and

Fig. 8 is a perspective view of a clutch unit which forms a part of the adjusting device.

It will be observed in the drawing that the adjusting device 10, when used for example in connection with a transom window 11, is mounted on the door-frame 12 adjacent the hinged side of the door 13 with which the transom window is associated, and operates to control the movement of the window 11 through the usual interposed mechanism 14C.

rThe adjusting device 10 includes a mounting. bracket 15, a longitudinally movable member 16 associated with the bracket, a handle 17 at the lower end of the member for transmitting to the same either a longitudinal or a rotary movement, and a clutch assemblage 18 which is contained within the mounting bracket and is adapted to lock the member against further longitudinal movement in either direction upon the member being rotated by means of the handle.

The mounting bracket 15 consists of an interiorly serew-threaded tubular portion 19 and an integral attaching base 20 at one side of and parallel to the axis of the tubular portion.

The longitudinally movable member 16 consists of a rod which is of non-circular, preferably square cross section. The member need only be of such length that a portion thereof will remain within the bracket during any extreme adjustment of the device, and is suitably swiveled at its upper end 21 to the lower end of an operating rod 22 adapted for reciprocatory movement in the mechanism li.

'The handle 17 may be of any desired type, and is advantageously one which extends radially from the lower end of the member a distance suliicient to provide means for operating the adjusting device conveniently and without unnecessary el'liort.

The clutch assemblage i8 which is the teature oit the adjusting device wherein the invention primarily resides, consists ot a plurality ot integrally associated clutch lingers 23 and an associated annular stop 2e for coaetion with the clutch ingers. rllhe clutch fingers are preferably termed in a single unit, but obviously may be formed in separate pieces. rlhe single unit embodying the clutch lingers 23 has an axial, preferably square passage which is adapted to encomaass the member in i` terlitting non-rotatale engagement therewith, and is characterized by a tapered nose portion 25 and an adjoining screw-threaded cylindrical portion :6 for screw-threaded engagement with the bore ot the tubular portion of the braeln et. rlhe annular stop 2i consists of a sleeve which freely encompasses the member 16 and is exteriorly screw-threaded for screwthreaded engagement with the bore ot the itulnllar portion ot the bracket. One end 27 of the sleeve has an annular portion which is engageable with the nose portion et the clutch unit to cam the several clutch fingers inwardly against the member when the nose portion oit the clutch unit is advanced in engagement with the annular portion of the sleeve upon rotation ot the member', and the other end 28 of tie sleeve has an enlarged polygonal portion for use in adjusting the position ot' the sleeve longitudinally within the bore otl the tubular portion of the bracket. fr set-screw 29 may extend through an aperture in the bracket into the bore ot the tubular portion thereof and bear against the sleeve whereby to lock the same in any desired position.

The operation of the adjusting device is as follows:

When the handle is in the position shown in Fig. G, the clutch lingers are tree from frictional engagement with the member regardless ot the position of the member longitudinally of the bracket, but, when the handle is turned to the right into a position substantially parallel to the plane of the base as shown in Figs. 3 and 4, the clutch lingers are turned with the member and, being in screw-threaded engagement with the bracket, are advanced against the end portion oi the sleeve and cammed inwardly by the same against the member whereby to lock the member against further longitudinal movement in either direction. ln order to release the member and permit further longitudinal movement of the same, it is only necessary to turn the handle in a reverse drection until the clutch lingers have been unserewed suliiciently Aaway trom the sleeve to permit their expansion and disengagement'i'rom the member. rlhe sleeve, be-

tf1. pomY `ing to the rigl t when locked in a position t removed as possible trom the path o t ie door. ln order to adapt the present adjusting device tor use with a door which is hinged along its lett-hand side as shown in 2, the bracket with its associated clutch need only be reversed as an entirety when being mounted on the door traine, whereupon the device will lock the member tinst further longitudinal movement upon being turned to the lett away trom the door.
