To all whom itmay concern:

Be it known'that I, JOHN B. FOLEY, a citizen of the United States, residing at New Haven, in the county of New Haven and State of Connecticut, have invented a certain new and useful Improvement in Sash Looks or Holders, and do hereby declare that the following is a full,-clear, and exact descrip tion thereof.

Reference being had to the accompanying drawings, Figure 1 is a perspective view of a car window lock embodying my invention; Fig. 2 a front elevation thereof, the bolt being shown as withdrawn in dotted lines; and

; Fig. 3 a horizontal section on. the line 33 of Fig. 1.

My invention relates to sash locks or holders, and more particularly to a lock adapted for use on the windows of railroad cars, and the object of my invention is to provide a lock of such construction that the same look is applicable to either the right or the left side of the Window; one whose construction will be simpler and more compact than the look now in use; and that will be more convenient of manipulation than the lock in common use; and to this end my invention consists in the lock or holder constructed substantially as hereinafter specified and claimed.

As is well known, the form of lock used on railroad car windows has an operating lever for retracting the sliding bolt, and considerable movement of the handle end of the lever is necessary to secure an adequate throw of the bolt. Any undue movement of the hand in operating the lock is not only objectionable on its own account, but the greater the movement of the lever, and as well the arrangement of the parts due to the employment of the lever, add to the bulk of the device as a whole. Moreover, with the lever type of look now in use, it is necessary to make the looks right and left, so that a double stock must be carried by the dealer to suit the requirements according to the side of the window on which the lock is to be used.

In constructing a lock to embody my invention, I employ a casing or housing in the form of an oblong chambered block, having on its upper and lower sides perforated ears 11 for screws for securing the casing to the sash, the casing being provided with holes or perforations in its opposite ends in which are slidably mounted a horizontal bolt 12. Fastened directly and rigidly to the bolt within the casing is an operating handle or finger piece 13, having ashank that passes through a slot in, the outer front wall-of-the casing, and outside ofthe-latter has aside surface that-is shaped or formed with such curvature as to be adapted for. the convene ient. application toit of the forefinger applied to the side thereofnext the window"frame,-so

that by lateral or side-wise pressure away from the latter, the bolt may be moved to disengage it from the locking hole, notch or keeper of the window frame. The bolt is moved to and yieldingly held in looking position by means of a coil spring 14 that encircles the bolt and has one end engaging a shoulder or enlargement 15 thereon, and its other end engaging the inner surface of one of the end walls of the casing.

Projecting horizontally outward from the front Wall of the casing, is a lug or ear 16, that constitutes a supporting surface for the thumb when the bolt is to be retracted by the application of the forefinger to the handle 13, and said thumb piece is so positioned that the bolt handle is moved toward it by the action of the forefinger thereon, and the side of the handle towards the thumb piece is recessed to provide at its top and bottom overhanging lips or flanges 17 to respectively engage the upper and lower sides of the thumb piece when the bolt is fully retracted, so that when the sash is to be raised or lifted, the strain or pressure will not fall upon the bolt, but will be applied to the thumb piece by the engagement of the lower lip or flange of the handle with the thumb piece, and thus the strain resulting from the lifting of the sash will be borne by the casing. I provide the bolt handle with the lip or flange at both top and bottom in order to provide an engaging surface between the handle and the thumb piece for lifting the sash whether the bolt is at the right or the left side of the window, and it will be a parent that by reason of the projection of the bolt handle and the thumb piece, at the front or outer side of the lock, the same look is applicable without any adjustment or change to either side of the window, whereas with the lever type of lock to which I have referred, where the operatin end of the lever protrudes at the side of t e lock, it is impossible to use the same look indifferently at either side of the window.

The ap lication of power to move the bolt by a han le directly connected to and forming a part of the bolt, instead of through the medium of a lever, not only affords the valuable advantage of applicability of the same look to either side of the Window without adjustment or change, but the amount of movement of the finger in operating the bolt need be no greater than the amount of movement necessary to disengage the bolt, whereas with the lever the amount of movement of the finger is greater than the extent of movement of the bolt, and I produce a simpler construction, am enabled to use a better form of operating spring, the device as a whole is much more compact, and the finger and thumb engaging parts are situated so that they can be more easily and comfortably caught hold of, and power applied to raise the sash more advantageously than is eases? I o the case with the lever type of lock generally used. 20

What I claim is In a sash lock or holder, the combination of a casing, a horizontally sliding bolt, a handle fixedly attached to and projecting from the bolt for engagement by the finger, 25 and a lug or ear projecting from the casing adapted for engagement by the thumb, the handle having a lug-engaging lip or flange, situated to engage an under surface of the lug.

In testimony whereof, I afiix my signature 3f) in presence of two witnesses.

JOHN B. FOLEY.
