Serial No. 450,531.

This invention relates to locking attachments useful for many purposes and particularlyof advantage for use as window and door locks. v

One of the objects of the invention is to provide a lock arranged for locking a lower window sash with an upper sash in a manner to prevent separation or independent movements of the windows relative to each other maintained in stationary relation with the window frame after it has been raised to permit ventilation or for other purposes.

Another object is to provide a window lock ofsuoh construction that an upper and lower sash may be pressed against each other to prevent a movement of air therebetween.

I I'he invention includes a lock which may be used upon doors as well as windows. It is an object to provide a lock which maybe operated conveniently, will be durable in use and may be practically manufactured.

With the foregoing objects in view and others to be mentioned, the invention presents a new and useful construction, combination and arrangement of parts as described herein and claimed, and as illustrated in the accompanying drawings, it being understood that changes may be made in form, size, proportion of parts and minor details as found to be of advantage,said changes beingwithin thescope of the invention as claimed. 1

In the drawings, Fig. 1 is a broken plan view showing parts of an upper window sash and lower sash with the window lock applied thereto, the upper sash and glass being in section. Fig. 2 is a side view of the parts shown in Fig. 1.

Fig. 3 is a plan view similar to that shown in Fig. 1, the frames of the locks being in section to clearly show the locking mechanism. Fig. 4 is a detail relating to Fig. 3, showing the parts in unlocked position. Fig. 5 is a detail relating to Figs. 1, 2, 3 and 4;, showing the plunger-bar andrelease-plate in longitudinal section.

Figs. 6, 7, 8, 9 and 10, relate to a modified form of the invention. Fig. 6 is a plan view showing a window lock applied to thesashes, the upper sash being in transverse section.

Fig. 7 is a plan view, being a detail relating to Fig. 6 and showing the parts disposed in unlocked position.v Fig. 8 is a detail relating to Figs. 6 and 7, showing the locking-bar and its frame in longitudinal section. Fig. 9 is a front view of the parts shown in Fig. 6. Fig. 10 is a front or side View of the lockingbar and its frame shown in Figs. 6, 7 and 8,

and used for locking 2., door. and to adjust a lower sash so that it may be Referring now to the drawings, and particularly to Figs. 1, 2,3, 4 and 5, for a description, the invention is shown and described in connection with a window frame 11 in which the upper sash 12 and lower sash 13 may have vertical sliding movements.

In order'that the objects of the invention may be attained as first mentioned I provide a pair of stop plates 14, each being secured to the inner face of a side rail of an upper sash as best shown in Fig. 2 of the drawings.

Numerals 15 indicate notches which are formed in and which open upon the inner edges of these stop plates, and while in Fig. 2 of the drawings only one notch 15 is shown,

it will be understood that similarnotches may be formed in said plates at longitudinal inter- .vals thereof, the use of said notches to be presently described.

Numerals 16 indicate a pair of lockingbars pivotally. mounted at 17 between their ends, said'bars being normally pressed into contact with the stop plates lei and notches 15 by operation of springs 18. Numerals 19 indicate covers for the locking-bars and springs 18 as best shown in Figs. 1 and 2 of the drawings, said covers being secured to the upperrail of the lower sash.

In order that the locking-bars'16 may have swinging movements to loclzed or unlocked positions I provide mechai'nsmconsistlng, in

part, of aspreader-member or plunger-bar 20 which is slidingly mounted on a base-plate 21 which is secured upon the upper rail of the lower sash. i

As best shown in Fig. 5 of the drawings the lower side of the spreader-.inember or plunger 20 is provided with a lug 22 adapted to slide in slot 23 of the base-plate 21, and by use of a handle 24; the plunger-bar may be moved, e g Working i th lo 23, and

maintaining the bar 20 at right-angles to the window sash 13.

Means are provided to normally prevent any movement of the plunger-bar 20 except by manual control of a person at the inner side of a window, this being a feature of importance to prevent unauthorized persons from gaining access to a building, said means consisting of a control-plate 25 of angular form and approximately of U-shape adapted to have a rocking movement, under control of a spring 26 (Fig. 5) which is mounted on a locking-pin or screw 27. Numeral 28 indi' cates a nut in which this screw is threaded, and these last named parts are mounted in a yoke 29, the arms of said yokebeing secured to the housing or cover 30 which is provided for the plunger-bar. v

As clearly shown in Figs. 3 and 4 of the drawings, the inner end of the plunger-bar 20 is provided with a head 42 operating as a spreader since it has outwardly curved or convex edges, and at b is indicated a slot which is formed in the upper face of this head, and at a (Fig. 5) are indicated a pair of recesses which are formed in the head-a and which open upon the slot 6. 6

By referring .to Fig. 5 of the drawings it will be seen that the screw 27 engages in one of the recesses c and is normally maintained in said recess by action of the spring 26, and this is the position of parts when the plungerbar has been moved rearwardly to the position shown in Figs. 1, 3 and 5 of the drawings. However, it will be understood that if the control-plate 25 is swung downwardly against the force of the spring 26 the screw 27 will be lifted from the recess 0 at one end of the slot Z) to permit the plunger-bar to slide outwardly of the housing 30 to the position shown in Fig. 4 of the drawingsone end of the screw 27 engaging in a recess 0 at the opposite end of the slot 7), and on account of the particular construction of parts as described the control-plate 25 must be pressed downwardly whenever it is desired to move the plunger-bar.

- The remaining parts to be described for causing a horizontal swinging movement of the locking-bars 16 from the recesses 15 consist, in part, of a pair of links 31, anda pair of segmental plates 32, one end of each link 31 being connected with one end of a' segmental plate 32--by means of a coupling-block 33, the opposite end of each link 31 being flexibly connected with a locking-bar 16 by means of a coupling-block 34.

The pivotal mountings for the segmental plates 32 are indicated at 35, midway bet-ween their ends, said segments and the coupling blocks 33 being movable within the housing or cover 30, and since the coupling-blocks are pivotally connected at their ends with the parts mentioned the forward and rearward movements of the plunger-bar do not result in any appreciable friction.

In operation, the control-plate 25 must first be pressed downwardly to permit a sliding movement of the plunger-bar 20 to cause locking or unlocking. By referring to Figs. 3 and 4 of the drawings it will be seen that an inwardly sliding movement of the plunger-bar will cause the curved edges of the head a of said bar to engage and move the adjacent ends of the segments 32 outwardly for moving the links and to cause the bars 16 to move into the recesses 15 of the stopplates, the screw sliding in the groove Z) for engaging in a recess 0, and the lug 22 of the plunger-bar moving in the slot 23 of the base-plate 21; and when the plunger-bar 20 is moved outwardly of the housing or cover 30 the curved edges of the head a of said bar will engage and cause the adjacent ends, op-

posite to those mentioned, of the segments 32 to cause an outwardswinging movement of the locking-bars 16 from the recesses 15.

It has been stated that the rocking movements of the control plate 25 is subject to the action of the spring 26, and it is obvious that adjustments may be made so that .a slight downward pressure upon the control plate will be suflicient to cause a release of the screw from a recess 0, and for this purpose the screw 27 may be rotated in one direction to cause the distance to be increased between its head and the nut 28, and the adjustments gagement with the catch 37, and the clasp which is pivotally mounted on the hook may have a swmging movement into engagement with the catch for pressing the rails of the sashes l2 and 13 against each other for preventing a movement-of air therebetween.

A modified form'oi? the invention is illus- 1 trated in Figs. 6, 7, 8 and 9 of the drawings. In this modified form no recessed stop-plates are used, but the upper sash is provided with a base-plate 39 having an elevated pocket 40 for receiving a locking-bolt 41, said bolt being disposed in a housing 42 which is mounted on a base-plate 43 which is secured to the lowersash. Numeral 44 indicates a controlplate for manually moving the locking-bar,

said plate having a swinging movement from a rivet 45, said rivet traversing the plate 44, the locking-bolt 41, the housing 42 and baseplate .43 as best shown in Fig. 8 of'the drawings. Numeral 46 indicates a spring which is mounted on the rivet 45 which normally operates to press one end of the control-plate 44 downwardly upon the housing 42 and therefore that end of said control-plate opposite to the spring may be lifted upwardly from the housing and may be swung horizontally.

The control-plate 44 is provided with a handle for use when moving it in a circles are, said handle consisting of a. pair of upright wings 4'? connected with each other by a rivet 48.

Numerals 49 indicate a pair of prongs which project downwardly from the end of the control-plate, said prongs being disposed in spaced relation relative to each other and disposed at the respective sides of the bolt 41, and therefore when the control-plate 44 has a horizontal swinging movement said bolt will move with said control-plate.

Numerals 50 indicate a plurality of apertures which are formed in the top of the housing 42, said apertures being disposed in a circles arc, the center of the arc being the rivet upon which the control-plate swings, and at 51 (Fig. 8) is indicated a lug which projects below the bottom of the control-plate 44 and which may engage in any selected aperture for maintaining the control-plate in a stationary position.

It will thus be seen that by use of its han dle the control-plate together with the locking-bolt 41 may have swinging movements for disposing said bolt 41 in locked relation with the catch-member or pocket 40, or may be swung into unlocked relation.

Means are provided for pressing the upper and lower sashes against each other as best shown in Figs. 6 and 7 of the drawings. Numeral 52 indicates a lug which is provided for the base-plate 43 and at 53 is indicated a hook which is pivotally mounted on the base-plate 39 of the upper sash, said hook being adapted to have a swinging movement for engaging the lug 52. Numeral 54 indicates a clasp or second hook which is pivotally mounted on the hook 53, and which may have a swinging movementto cause its eccentric edge to engage the lug 52 for pressing the sashes against each other.

Fig. 10 of the drawings illustrates the lock ing device applied to a door 55 and to the door casing 56, said locking device being the same as shown in Figs. 6, 7 8 and 9 in all respects except the fact that the lug 52, the hook 53 and second hook or clasp 54 are not used, and it will be understood that the opera ation of parts shown in Fig. 10 is the same as corresponding parts shown in Figs. 6, 7 8 and 9 of the drawings.

I claim as my invention,

In a device for locking a window sash with a second window sash, said first named sash being provided with a pair of recessed stop plates, a pair of locking-bars pivot-ally mounted on the second sash, a housing mount ed on the second sash, a pair of segmental plates each pivotally mounted midway between its ends in said housing each having a connection with a locking-bar, a spreadermember provided with a slot and a pair of recesses opening on the slot and having a head provided with outwardly curved edges and disposed between the segmental plates, an angular control-plate seated on said housing, a yoke above the control-plate and having its arms secured to the housing, and a resiliently mounted locking-pin traversing the yoke and control-plate to engage in the slot of the spreader-member, said spreadermember being movable in one direction for moving said segmental plates, the'lockingbars moving into the recesses of the stopmembers and said locking-pin moving from the slot to a recess of said spreader-member.

In testimony whereof, I affix my signature.
