COMBINED SASH-LOCK AND BURGLAR -ALARM.
Specification of Letters Patent.
Patented June 14:, 1910.
Application filed June 28, 1909. Serial No. 504,923.
To all whom it may concern:
Be it known that we, FREDERICK K. HEU- PEL and Isaac B. N ORDLINGER, citizens of the United States, residing at Washington, District of Columbia, have invented certain new and useful Improvements in Combined Sash Locks and Burglar Alarms; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.
This invention relates to a combined sash and door lock and burglar alarm, and has for its object to provide a device which will effectually lock a window sash and which will give forth a signal just as soon as it is attempted to raise or lower the sashes of a window or open a door. e are aware that there are a large number of devices designed for this purpose but it is our object to provide a simple alarm which can be easily and quickly thrown into and out of operative position and which cannot be thrown out of operative position by the insertion of a tool from the outside of a window between the upper and the lower sash.
This invention consists in the novel construction of the combined sash and door lock and burglar alarm in combination with means for holding the same in operative po sition in such manner that the alarm cannot be forced out of operative position by a tool or implement forced between the upper and lower sash.
Referring to the accompanying drawing: Figure 1 is a plan view illustrating our invention in operative position. Fig. 2 is a fragmentary vertical sectional view through an upper and a lower sash of a window illustrating the alarm in operative position. Fig. 3 is a similar view illustrating the position the alarm assumes when it is attempted to force the same out of operative position by the insertion of a tool or implement between the upper and lower sashes of a window. Fig. a is a similar view illustrating the lower sash in a slightly'raised position. Fig. 5 is a plan View illustrating one form of an alarm engaging strip which is arranged on the upper sash of a window. Fig. 6 is an elevation of the lower portion of a door and jamb illustrating the alarm in operative position. Fig. 7 is a horizontal sectional view showing the door in closed position, and Fig. 8 is a similar view showing the door in slightly open position at which the alarm operates.
Like characters of reference indicate the same parts throughout the several figures in which:
1 indicates the upper sash and 2 the lower sash of a window.
3 indicates the combined sash lock and alarm which as shown in the several figures comprises two hinged members 4 and 5, the hinged member 5 being designed to be secured on the upper edge of the lower sash 2, while the hinged member 4 swings on the lower hinged member 5 as illustrated in full and in dotted lines in Fig. 2.
6 indicates the alarm which is preferably a bell of conventional form, said bell having mechanism within the same (not shown) inclosed within a casing 7. Entering the casing 7 and operating the mechanism therein is a plunger 8.
We prefer to employ any suitable spring mechanism such as can be wound up or set by rotating the bell 6 although obviously any other style of mechanism may be employed.
Secured to the upper sash 1, as for instance shown in Fig. 1 is the plunger engaging strip 9, said strip extending a short distance along the upper sash and is provided with a series of projections 10 preferably punched out of the strip 9. V'Vhen employing this construction the end of the plunger 8 of the alarm is perfectly flat as illustrated at 12 in Fig. 1. Fig. 5 however illustrates a modified form of strip which is provided with a series of perforations 13 within which the plunger 8 enters. When employing this form of strip it is preferable to point the plunger 8 in order to insure an easy entrance of the same in the perforations 13.
Pivotally carried on the hinged member 5 is a leaf spring let, said leaf spring bein curved as illustrated in the drawing and having its free end in engagement with the hinged member 4 and acting against the same to maintain the alarm in position shown in Figs. 2, 3 and 4.
When it is desired to swing the alarm out of operative position and into position shown in dotted lines in Fig. 2 the pivoted leaf spring 14 is swung into position shown in dotted lines in Fig. 1 which allows the hinged member 4 and the alarm to be swung inwardly in position shown in dotted lines in Fig. 2 in such manner that the lower sash may be raised and lowered at will.
WVere it not for the pivoted spring 14 acting against the hinged member 4 and maintaining the alarm in proper operative position the insertion of a tool or instrument A between the upper and lower sashes of a window as illustrated in Fig. 3 would quickly throw the hinged member 4 and alarm out of operative position and into position shown in dotted lines in Fig. 2. In our constructon, however, the insertion of a tool or instrument A, as illustrated in Fig. 3 between the upper and lower sashes of a window, will simply raise the plunger 8 out of engagement with its engaging plate 9 and force or throw the hinged member 4 and alarm into position shown in dotted lines in Fig. 2. hen, however, the alarm is in position shown in Fig. 3 the sash can obviously be raised without sounding the alarm, and can for instance be carried in position shown in Fig. 4. The raising of the lower sash 2, however, raises the alarm and carries it farther away from the lower sash until it will leave the tool or instrument A at which time it will instantly engage the plate 9 and cause the alarm to be sounded and at the same time effectually lock the sash in a slightly raised position.
\Vhile the leaf spring 14 effectually insures the proper operation of the lock and alarm the alarm and hinged member 4 can be quickly and easily thrown out of operative position from the inside of a window by simply swinging the leaf spring 14 on its pivot to disengage the same from the hinged member 4.
Referring to Figs. 6, 7 and 8 which illustrate the alarm as applied to a door it will be seen that the hinged member 5 is applied to the jamb 15, the hinged member 4 extending over the edge of the door 16 to the stile to which the plate 9 is secured. When the leaf spring 14 is in position shown in Figs. 6, 7 and 8 the plunger 8 of the alarm is in position for engagement with the tangs or projections 10 on the plate 9. As soon therefore as the door 16 is opened into position shown in Fig. 8, the plunger 8 is engaged by one of the tangs or projections 10 and forced inwardly thus sounding the alarm. When it is desired to throw the alarm out of operative position the leaf spring 14 is simply thrown on its pivot into position shown in dotted lines in Fig. 1 and the hinged member 4 and alarm are swung back over the jamb 15 in which position the door can be openedor closed without sounding the alarm.
Having. thus fully described the several parts of our invention what we claim as new and desire to secure by Letters Patent of the United States is A device of the character described comprising a member adapted to be secured to the lower sash of a window, a hinged member 44, an alarm carried thereon, a plunger on said alarm, an engaging strip adapted to be secured to the upper sash of a window, said engaging strip being provided with means for engaging the said plunger, a leaf spring pivotally connected to the first mentioned member having its free end normally in engagement with the hinged member for holding the said plunger in engagement with the said strip said leaf spring being adapted to be swung on its pivot out of engagement with the hinged member, substantially as described and for the purposes set forth.
In testimony whereof, we afiix our signa' tures, in presence of two witnesses.
