FASTENER FOR MEETING-RAILS OF SASHES.

SPECIFICATION forming part of Letters Patent No. 394,962, dated December 25, 1888.

Application filed fieptember 8, 1888. Serial No. 284,879. (No model.)

To [LZZ whom it may concern.-

Be it known .that I, \VILSON P. DODSON, a citizen of the United States, residing in the city and county of Philadelphia, and State of Pennsylvania, have invented certain new and useful Improvements in Sash Holders, of which the following is a specification.

The present invention relates to that class of sash holders or looks which comprise a case or bolt section, a movable boltmounted in said case, and a keeper with which the end of the bolt engages as it is moved for that purpose.

The invention, however, more particularly relates to means whereby such movable bolt is prevented from accidental movement, and whereby the liability of unlocking the sashholder is obviated; and it consists 'i 11 the novel structure hereinafter fully set forth.

The accompanying drawings illustrate the invention as applied to a sash-holder of the class forming the subject-matter of United States Letters Patent Nos. 2:3 38,997 and 379,2 9; but it obvious that it might be applied to any class of sash-holders employing a movable bolt, which may be accidentally unlocked, in which (.lra\\'.ings

Figure 1 is a perspective view of the under side of the case or bolt section of a sash-holder containing the invention. Fig. 2 is an end elevation of the same. Fig. 3 is a transverse sectional elevation of the same, taken on the line 3 3 of Fig. 1. Fig. 4 is-a vertical sectional elevation through the case and keeper taken substantially on the line at 4:, Fig. Fig. 5 is an elevation of the bolt remox'ed from the case. Fig. (3 is an elevation of the inner side of the bottom confiningplate. Figs. 7 and 8 are mmlitications of the invention.

The sash holder or look takcn'for illustration is substantially like that illustrated in Patent No. 379,2 8; and it consists, as in said patent, of a case or bolt section, A, having an open socket, d, and extended horizontal flan ges 2, providing means for securing the case or section to the upper railof the sash 13. Within the socket d is seated a movable bolt, C, having a locking-linger, a, at its outer end and provided with an operative handle, Z, that extends through a cam-slot, c, in said socket of the case or bolt section. With this portion of the sash-holder co-opcrates a keeper, E, that is secured to the meeting-rail of the other sash, F, and with which keeper the end of the bolt C engages as it is turned for that purpose and by which the two sashes are secured.

In practice it has been found desirable to form the socket (Z of a size sufficiently large to permit the free movement of the bolt therein as it is moved to lock and unlock the sashes. By reason of this fitting of. the bolt in its socket, and in consequence of the fact that its locking-finger a is, preferably, so formed on the end of the bolt that its major portion is all upon one side of the axis of the bolt, it often happens that if the sashes be rattled when the bolt is in its locked position the keeper will tend to bear down upon the finger of the bolt and rock it upon its axis sufficiently to cause the cam-slot, acting upon its operating-handle,to entirely withdraw the bolt from its locked position, and thus unfasten the sashes. In order to obviate this disadvantage in the use of such sash-holders, the device is provided with a locking-detent, H, that is adapted to hold the bolt in its locked position against accidental movement without interfering with the ready operation of the bolt by means of its handle I). The detent ll is, in the preferred construction, provided upon the inner side of a bottom confining-plate, l), which detent, when the bolt is moved to its locking position, is adapted to enter a groove, recess, or depression, 2', formed in the bolt 0, as shown in Figs. 1 and 3. The detent H is preferably a small rib, formed integral with the plate D and extending more or less in the direction. of its length, and the groove, recess, or depression 2 is also formed in the bolt (1 in the direction of its length and in such position with respect to its lockingtinger c that when said locking'finger is in position to engage and lock with the finger E, said groove, recess, or depression will be in position. to be engaged by the locking-detent ll. In consequence of the construction of the bolt t, hereinbefore pointed out, it follows that any tendency to rock the bolt by the rattling of the sashes, so as to cause the keeper to bear down upon the locking-finger a, will be to cause the bolt to be more firmly pressed in contact with the locking-detent, and be thereby prevented from turning; but it will be seen that as the bolt has sufficient play in made.

its ease to :l'reely pass said loeking-detent it will oiier no resistance to the proper move- .ment ot' the bolt when it is operated through its handle I).

It is obvious that the invention is not limited to the location ol the loeking-detent and the groove, reeess, or depression 1', so long as the detent bears sueh relation with respect to the bolt that it will loek the latter against aeeidental movemei'it. As shown in Fig. 7, the detent II is jirovided on the bolt while the recess 1', with whieh it engages, is provided in the face of The plate 1). In Fig. 8 the detent ii is shown as formed on the side of the soeket (l, eontz'tining the bolt, the reeess 1' being provided in the bolt.

The plate I) is shown as seated in a recess formed in the under side of the ease or bolt section A, and held therein against aeeidental dis iilaeeinent by means of tmigues. No claim, however, is herein made to sueh a plate, as the same forms no part of my invention, but is in fact the invention 01 another, for which application for Letters Patent is about to be So far as the presentinventioni s eoneerned, however, said plate may be thus seenred to the ease, as shown in Figs. 1, 2, 3, and S, or it maybe a loose plate simplyseated in the recess and held from displacement by the rail of the sash, when the ease is seeured thereto, as shown in Fig. 7.

\Yithout limiting myself to the preeise eonstruetion and arrangement of parts shown, I elaim- 1. A sash-holder having a rotating loekingbolt and a loekingdetentarranged to prevent the accidental rotation of the bolt when in its looking position, and to permitthe rotation of the bolt under the force of the operai ing-handle, substantially as described.

2. lheeombination, with the ease of a sashholder having an open soelcet, a bottom plate, and looking-detent formed on said plate, of a movable bolt nnnlnted in said. soeket and p.r(')vide('l. with a recess for engzigement with said detent when in its loeked position, substantially as deseribed.

ii. The (-ombination,with the easeol' a sashholder having an open soeket wit-h a eam-slot therein, a lni ttom plate, and loehing-detent formed on said plate, ol? a movable bolt mounted in said soeket having an operatinghandle projeetingthrough the eam-slot of the socket and provided with areeess tor engagement with said detent, substantially as de seribed.

In testimony whereof I have signed my name to this specification in the presenee of two subscribing witnesses.

WILSON l. DODSON.
