To all who/m, t may concern.'
Be it known that I, Bonner C. SPENCER, Jr., a citizen ofthe United States, and a resident of River Forest, in the county of Cook and State of Illinois, have invented -a certain new and useful Improvement in Casement-Window-Sash Adjusters, of which thevfollowing is a full, clear, concise, arid exact description, reference being had to the accompanying drawings, forming a part of this specification.
My invention relates to improvements in Casement window sash adjusters, and is par# ticularly ,concerned with the provision of a novel type of easement window lsash adj uster by means of which a easement window sash can be easily and quickly adjusted, as desired, and held in its adjusted position.
The objects of my invention are:
First: To provide a easement window l sash adjuster. comprising van arm'pivotally mounted upon a 4portion of the'windlow frame, means for movin the arm about its pivot point, `and a slida le connection be-. .tween the outer endl of .the arm and a mem- .ber securedto the sash of suchv construction that the arm will 'cause the window to open or close as it is moved in lopposite directions about its pivot point. l Second: To provide a construction of the character described, `in which theco-acting' means at the end of the arm and on the sash comprise means for locking the arm and consequently the sash'in any one ofa plurality of different positions.l
Third: To provide an adjuster such as described, which can be installed without notching or otherwise mutilating the screen which is interposed between the sash and the operator, or requiring a stop member under the screen. 1
Fourth: To provide a easement window sash adjuster such as described, in which the parts ecured to the window frame are made Hush with the surface ofthe window frame.
Fifth: To provide a easement window sash adjuster comprising a pivoted arm, a handle for moving said arm about its pivot point, and a fulcrum about which said arm can be tilted, the said fulcrum being so positioned relative to the arm and the handle that the pressure exerted upon the handle bodiment of my invention.

Referring for the present to Figures 1 to 6 inclusive, the embodiment of my invention disclosed therein comprises a fulcrum plate 15, theedge of which is provided with an annular flange 16, which, together with the bottom, forms a cylindrical cup-like member having the outturned iange 17. This cup-like member is let into an opening 18 in .the stool 19 of the window frame, the flange 17 being received in a suitable countersink of the opening 18. A cylindrical boss 20 projects Cil ` ator presses downwardly upon the handle` upwardly centrally of the plate 15, forming with the' flange 16 an annular groove which receives the ring 21, having the central bore 22 for 'receiving the'boss 20. The ring 2l is thus journaled upon the boss 20. The bore 22 tapers outwardly toward its inner end to permit the ring to be tilted upon the boss, as will be described later on.
Radially elongated projections 23 project downwardly or inwardly from the ring 21, there being a pair of these projections disposed upon opposite sides of the lring and in alignment with` each1 other so as to form a fulcrumaboutwhich the ring 21 can be tilted. These fulcrums bear upon the fulcrum plate15. The ring 21 is countersunk',`
as shown at 24, and projecting upwardly from the bottom of this countersink are a second pair of projections 25, which are located in a vertical plane passing through the projections 23. A disk 26 issecured tothe boss 20 by means of the screw 27, and forms a fulcrum plate for the projections 25.
Formed integrally with the ring 21 is an arm which first projects upwardly a slight distance, as shown at 28, and then projects substantially in a horizontal direction, as shown at 29. The free end of this arm is provided with a head 30, from the lower side of which thepin 31 projects, and in which are mounted one or more springpressed plungers 32, which are urged outwardly by the` springs 33, confined in suitable bores in 'the head 30, as shown'in Figure 3. The head 3() slides in a channel shaped member, which is secured to the bottom rail 34 of the sash, and comprises the bottom member 35, which is secured to the sash by screws 36, or any other suitable means, 4and the horizontally extending flanges 37 and 37, *the outer ends of which are danged inwardly, as 'shown'at 38, to provide means for retaining the head 30 in the channel shaped member. rllhe lower flange 371 is provided with a plurality of longitudinally spaced openings 39, adapted to receive the projecting end of the pin 31. The .plungers 32 are pressed outwardly against the inner side of the flange 37, and yieldingly hold the projecting end of the pin 31in whatever opening 39 in which it happens to be positioned.
For thepurpose of moving the arm 29 to position the sash as desired, 'llr provide a handle comprising the bar 40, one end of which is turned at an angle thereto, as shown at 40', to be received in a socket 41 formed in the ring 21.
`With the handle inserted as shown` when it is desired to adjust the window the oper- 40, ythereby tilting the ring 21 on the fulcrums 23 and 25, these fulcrums being so positioned that the plane extending through them divides the angle roughly formed by minore can cause the sash 34 to move toward either its open or closed position, as the case may be, and by then relieving they downward pressure on the handle 40, and moving it in either direction, can cause the pin 31 to p come into registry with one of the openings 39 and thus lock the sash'in any desired position, the spring-pressed plungers 32 causing the pin 31 to be yieldingly held -in the opening 39. lt will, of course, be
understood that when the arm 29 is positioned as shown in' full lines in Figure 1 the window will be held in its closed position.
llt will be noticed from the above description, and from the drawings, that the tops of the flanges 17 and the topof the ring 21 are flush with the top surface of the stool 19 of the window, so that the bottom rail of the screen 42 can extend directly across the ring 21 without the necessity of cutting or notching the screen, and that, at the same time, no openings are left which will permit the entrance of bugs, iies and other insects.
The embodiment of my invention illustrated in Figures 7 to 12 inclusive is in all respects substantially identical with that shown in Figures 1 to 6 inclusive, except that the fulcrum plate 15 is secured tothe top of the stool 19, and the boss 2() projects upwardly therefrom so that it is necessary Ito cut a notch 45 in the bottom rail 46 ot' the sash (see Figure 11) to receive the fulcrum plate, the boss and the ring 21. ln this embodiment, l have also shown the bore 22 as being tapered outwardly from the center in opposite directions to permit it to be tilted about the fulcrum projections 23 and 25. ln this construction, the projections 25 are elongated more than those shown in Figure 5. ln this embodiment, ll have also shown the ring 21 as being provided with a projection 21, in which a socket for receiving the handle 40 is formed. f
Otherwise. the construction ot' the apparatus shown in Figures 7 to 12J-inclusive is substantially the same as that shown in Figures 1 to 6 inclusive, and its mode of operation is identical therewith.
From the above description. it will be apparent that l have provided a easement window' sash adjuster of such construction that it can be easily and quickly applied to a easement window; that it can be so attached to the widow that notching or other mutilation ot the screen sash is unnecessary, and

tions, sufliciently large to permit lthe entrance of insects, and that it is exceedingly simple in constructionand economical tov manufacture.
One of the' features of my improved construction which isof very considerable importance is the location of the ulcrum projections on the ring, which are so positioned that when downward pressure is exerted upon the handle this pressure. will be effective in lifting the` outer end of the arm without the arm twisting in a direction to bind the head 30 in the channel secured to the sash, which is a fault quite common with types of easement window sash adjusters heretofore proposed. Q
