To all whom it may concern; 1

Be it known that I, FRANK F. SMITH, a

. citizen of the United States, and a resident and the like, and particularly to means for suitably adjusting such locks with respect to then sashes and for more securely locking said sashes.

It has for its object to afi'ord, to looks of this character, and without impairing their holdingproperties, a slight adjustment in order to overcome inaccuracies in the attachment of the said lock to the sashes, whereby the lock may be fully operated to securely lock the said sashes, and to so construct the said lock that-in case it should not fully close, to prevent-it from being opened from the outside.

The nature of .my inventi n will be best understood in connection with the accompanying drawings, in which Figure 1 is aplan view of the improved lock secured to the sashes of a window. Fig. 2 is a sectional View taken on the line 2-2,

Fig. 1. Fig. 3 is a plan view, and Fig. 4 an elevation of the stopsfor the holding member. Fig. 5 is a partial sectional view taken on the line 5-5, Fig. 1. Fig. 6 is an end view of the finger piece and lever shown in Fig. 5. Fig. 7 is a sectional view through the sash reinforce, bearing and adjusting screw, illustratin .the manner of riveting the bearing to sai sash, and reinforce. Fig. 8 is a detached perspective view of the bearing to be secured to the window sash and reinforce.

1 Similar characters of reference designate correspdnding parts throughout the several views.

Referring now to the drawings, the lock proper may be of any convenient and suit-g able form, the holding member or keeper 1 0 of'which is attached by means of suitable screws 11 to the outer sash 12; and the locking member 13 by means of screws 14, to the inner sash 15. In case the lock be used in connection with windows of the sheet metal type, as shown, securing plates '16 and 17 are riveted to the inside of the corresponding sashes and the lock members f and 14. Otherwise, the members are screwed directly into the sashes. In securing these members to their respective sashes, it is frequently found that, especially when secured to sheet metal sashes in which the screw holes are necessarily previously located, the said members do not cotiperate exactly so that frequently the locking member 13 does not completely fit its holding member or keeper 10, the two members being too close together or too far apart so that the cam portion 18 can be turned only a slight distance under the keeper 10. To enable the two members to be adjusted with respect to their sashes,-l provide either or both of said members with an adjusting screw 1%, which screws into a tapped hole 20 made in the wall of the keeper or the locking member, as shown; and I also pro-- vide slots 21 in said members, and through which the fastening screws 11 and'14 pass, to accommodate the adjustment. The screw 19 passes'throu'gh a bearing 22 which is secured to the window sashes or riveted to thesecuring plates 16 and 17. V, A shoulder 23 is provided on the said screw 19 and in conjunction with the bearing causes the member to be moved inwardly or outwardly according as the screw is turned, the screws 11 or 14 of course having been first loosened. The said means forms also an additional securing means for the lock members. Only a very slight adjustment is requlred as a rule, but this adjustment is very desirable, and its lack is extremely annoying attimes.

I When, even with the adjustment set forth or due to carelessness, it happens that the locking member 13 does not completely fit its keeper 10, I have provided means wherethe said locking member is prevented from being moved from the outside 1n a direction to unlock the sashes 12 and 15. For this purpose I haveprovided the base 25 upon which the holding member 13 1S mounted to turn, with one or more stops or crown teeth 26 inclined to permit free movement over same only in a direction to lock the sashes. A lever 27 is pivoted within a slot 28 of the finger piece .29 of said member 13 andis sprin pressed at its outer'end by a spring 30. t its inner end 31 it is bent downwardly and extends through the said finger piece to engage with the stops or '26. By depressing the outer end of levr 27 in opposltion to the spring 30, the

inner end 31 is raised out of engagement with the said stops 26, and the locking member 13 may be moved into any position. Upon releasing lever 27, the end 31 is depressed again due to the action of the spring and, engaging the particular stop with which it happens to make contact, securely locks the member 13 against turning in a direction to unlock the sashes. The arrangement 'set forth obviates the necessity of employing the internal springs common to this style of lock, the coiled spring 30 being all that is required.

'upon the upper surface of said base and which moves in contact with said ratchet, and which holding member has an inclined portion adapted to engage beneath the hook portion of said keeper, and an operating arm provided with a vertical and radially extending slot; and a spring-pressed lever pivotally secured in said slot, theouter end of which lever projects above the upper surface of said operating arm, and the inner end of which extends downward and through a slot provided for that pur-i pose in said holding member and into'position to engage with the ratchet stop aforesaid. I j

2. In a lock of the character described,

the combination with a keeper memberprovided with a base of alocking member provided with a base and means for adjusting either of said members on the sash to which it is secured, said means comprising a screw tapped at one endlnto ancpenmg 1n the wall of the base, said screw being provided' between its ends with a shoulder, and a bearing secured tightly to the window sash to which the member is attached and adapted to engage the shoulder on said screw whereby when the latter is turned the mema s ring-actuated lever provided on saidhol ing member whereby to lock the same against rotation in one direction on said base, either of said members being provided with" elongated slots for the reception of the fastening screws, and adjusting means provided on either of said keeper or looking members comprising a screw tapped at one end into the wall of the base and provided between its ends with a shoulder adapted to engage with a bearing secured tightly to the window sash, substantially as described. 1

4.. A lock of the character described, comprising a keeper and a locking member, either of which is provided with a screw tapped into the wall. of the member at one end, a bearing immovable with respect to ,the screw, and adapted to engage a shoulder formed on the latter whereby to adjust said member with relation to the sash to which it is secured, said locking member comprising a base and holding member mounted to turn thereon, and means provided on said holding member whereby to lock; the same against rotation on the base in one direction at different points in its rotation.

Signed at Newark in the county of Essex and State of New Jersey, this 27th day of July A. D. 1909.
