Application led March 30, 1915. Serial No. 18,163.

T o all whom it may concern:

Be it known that I, ULYssEs GRANT Mc- QUEEN, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Casement-Adjusters, of which th following is a specification.

This invention relates to easement adjusters.

The 4adjuster herein referred to is particularly designed for use in connection with that type of easement which is free for vertical sliding adjustment and also for horizontal swinging movement. It is, therefore, deemed advisable to mention and to properly emphasize that among other objects in view, the principal points of advantage in the structure lie in its adaptability to easements of the kind mentioned and to also invite attention to such features of the structure which satisfactorily contribute with one another to minimize friction between the working parts of the structure at the time of the initial opening of the casement or the closing thereof; and, further, the provision of means which will properly accommodate the vertical movement of the easement and at the same time hold the easement at any desired point in its horizontal adjustment. j

Another object of the invention is the provision of a easement adjuster, which, on a predetermined movement of the easement in a, horizontal direction, the easement may be frictionally held in its adjusted position, but in such manner that will permit of its further manual adjustment in a horizontal direction without the necessity of manually actuating the adjuster itself.

Aside from the eXtreme simplicity and practicability of the structure, it is also desired that notice be given the manner in which the friction between the sliding parts of the adjuster can be regulated to suit ordinary wear and tear of the parts and to also prevent the Casement from being accidentally moved from its intended point of adjustment.

In the accompanying drawings Figure 'l is an elevation of a window structure, showing in dotted lines the position of the adjuster on vertical movement of the casement and the normal position of the casement adjuster in full lines. Fig. 2 is a vertical section through the same, showing the easement in a partly-opened position. Fig.

3 is a perspective view of the adjuster.`

Fig. 4 is a longitudinalV section therethrough. Fig. 5 is a transverse section therethrough. Fig. 6 is a longitudinal section through both members of the adjuster and illustrating the means for limiting the sliding movement in one direction of one of the members within the other. y

rEhe adjuster, as stated, is particularly designed for use in connection with easements which are free to slide vertically and to also swing horizontally. The easement shown in the accompanying drawings and illustra-ted at C is of the inwardly opening type. However, it is understood that it may be just as effectually used in connection with a easement which is to swing in an outward horizontal direction if such be advisable.

The adjuster consists of two mating members 1 and 2, the former being in the nature of a tube and the latter in the form of a rod, which is free to slide in a longitudinal direction within the tube and also free to rotate therein. The tube is closed at one end by a cap v3 which has an integral stud 4 rising in a vertical direction therefrom and passing through a double frusto-conical passage 5 formed in an attaching plate or bracket 6 which may be screwed or otherwise suitably secured to the frame at the top thereof at a point adjacent to the upper horizontal rail of the easement. The passage 5 has its branches Av and B arranged so that' the small end of one branch has its walls directly merged into the small end of the walls of the other branch. ln this manner it is seen that the stud 4 is permitted to rock or turn in the bracket. At this point, it is stated that this adjustment is preferred, and in fact, necessary, in order that the device will accommodate itself to a corre.

sponding movement of the easement in a vertical direction. Interposed between the cap 3 and the bracket 6 is a spring 7 which serves to prevent undue rattling of the parts.4

At the opposite end of the tube is a cap 8 having a shoulder 9 which forms a stop against which the coacting shoulder 10 on the rod 2 is designed to engage so as to limit the outward swinging movement of the rod and, consequently, prevent its entire separation from the tube l. The rod 2 freely slides through the cap 8 and through the tube l and, as shown, it is provided at suitable points in its length with circular grooves 11.

ment of the rod 2. The outer spring, of course, bears against the plug 13 and incident'to the fact that* the latter is sary to a 'equalities in the movement thereof.

threadedly adjustable within the cylinder, it ofcourse, follows that the Ispring' may be p aced under such tension as may be necesroper retention of therespective parts'1 and 2 of the adjuster. The spherical body or latch element 14 when extended into anyone of the grooves 11 serves to hold the rod securely inits adjusted position but it does not hinder such free rotation of the rod as is necessary to'accommodate lateral in- It is desired that the'v friction between at certain times in the movement of the casement so as tolpermit the latter 'to be linitially movedV to its open position or to its full closed position, and purpose, the rod is of reduced diameter through a section of its length such as illustrated vat 16. It is seen that when the mentioned reduced portion of the rod is within the tube and disposed at right angles to the axis of the cylinder 12, the ball latch element 14 will'bear` thereagainst and as the i springis not compressed to the extent that it is evident that the two parts,

' sage and through it is when engaged in one of the grooves 11, namely, the tube 1 andthe rod 2 may move with more relative freedom and the casement may then be properly adjusted with relation tothe frame without any strenuous or laborious effort of the operator.

The extremity of the reduced end 16 of the rod,2 is provided with a passage 17v which is somewhat similar to the passage formed in the bracket 6. Through this pasthe ears of the bracket 18 is passed a screw 19. -The bracket 18 is adapted to be screwed or otherwise suitably secured tothe easement and as a result of the just-described manner of connecting the bracket to the rod, the rod is free to rock slightly fromfthe bracket. The bracket 18 is, of course, disposed at right angles to the bracket 6 and by connecting'the tube 1 and the rod 2, respectively, Awith both of the brackets referred to, satisfactorily accommodated not only in its described movements but in any other irregular movements thereof as m'ay result from the)y 'latch member andthe sliding rod be varied to accomplish this the easement is most constantoperation of a structure of this naand horizontal swinging easements, comprising a bracket adapted to 'be secured to the frame, a tube mounted to tilt vertically and swing horizontally from said bracket,a rod sliding in s aid tube and free to 'oscillate therein and provided with spaced annular grooves and a yieldingly mounted spherical lockingbody lcarried bysaid tube and adapted to be .successively projected into said grooves as vthe rodis adjusted longitudinally therein.

2. A holding device for vertically movable and horizontally lswinging easements, comprising, a bracket adapted to be secured to the `frame, a tube mounted to tilt vertically and swing horizont-ally from said bracket, a rod sliding in said .tube and free to oscillate therein andy provided with spaced annular 'grooves and a yieldingly mounted spherie 85 cal locking body carried by said tube and adapted to be successively projected into sald grooves as nally. therein, the said rod having a transwversely restricted portion adapted to freely movement of the rod from the tube and on the normal projection of the rod in thetube. 3. A holding device 'for vertically movable and horizontally swinging easements,l

the rod is adjusted longitudi-y co-act with the iirst stop to pass over said locking body initially on limit the projection of the rod from the tube, v

and a securing device carried by the 'tube and co-acting w1th the rod to hold thesame against movement in the tube.

4. A holding device for vertically movable and. horizontally swinging easements, comprismg, tally and to tilt vertically from the frame, a rod adapted to be mounted to swing horizontally and' to tilt vertically4 4from the casement and with the tube and mounted to slide in said tube, a member having a stop, said member being secured to the tube, a stop formed on the `rod and adapted Vto coact with the first stop,'and a locking device carried byl said member and adapted to co- 4act with the rod to hold the latter adjusted in the tube.

In testimony whereof I aflix my signature in presence of two witnesses.
