B'URGLAR ALARM. No. 364,637. Patented June 14, 1887.
l/l/f 5555'sy UNITED.. STATES PATENT OFFICE.
EvEnErr o. ELLWooD, oF GREENs FARMS, CONNECTICUT.
SPECIFICATION forming part of Leners Patent No. 364,637, dated June 14, las?.
To all whom it may concern.-
Be it known thatI, EvERETrC. ELLvvooD, a citizen of the United States, residing at Greens Farms, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Burglar-Alarms; and I do hereby 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 Inakeand use the same.
My invention relates to t-hat class of burglaralarms in which an alarm is given by detonation, and has for its object to provide a device of this class which shall be simple in construction, certain in operation, may be attached to -any door or Window without the necessity for skilled labor, and which may be made so cheaply as to be within the reach of all. With these ends in view I have devised the simple and novel construction, of which the following description, in connection with the accompanying drawings, is a specification, numbers being used to indicate the severahparts of the device.
In the drawings, Figure 1 is a side elevation illustrating my invention as applied to a window, the view being from the -outer side and the sash being indicated by dotted lines; Fig. 2, a front elevation corresponding with Fig. 1; Fig. 3, a view corresponding with Fig. 1,show ing the device as applied to a door; and Fig.v 4 is a slightly modified form, also shown as applied to a door.
Turning now to Figs. 1 and r2, 1 denotes the 35 jamb shown in section, and 2 the bead, the
parting'strip being removed. g 3 (see dotted lines in Fig. l) denotes the sash,and 4 the glass. The entire device consists of but three castings, a pin, and a spring. 5 denotes a catch-plate, which is secured upon theinner side of the window-sash. The other parts are all attached to the bead.
Application filed February 11, 1867. vSerial No. 227,289. (No model.)
through which the pin passes and around which the spring is coiled, as shown in Fig. 2.
.The hammer may be made of any preferred `form. I preferably, however, provide a teat,
15, which strikes the head of the cartridge when the hammer is released.
16 is a projection on the hammer, which is adapted to engage the catch-plateto set the device. The set position of the device when applied to a window is clearly shown Lin Figs. 1 and 2, and the released position is'shown in dotted lines in Fig. 1.
To set the device it is simply necessary io raise the window slightly, so that projection 16 on the hammerwillpass underthe catch-plate. The window is then dropped to its ordinary position, the hammer being locked in the raised position by the catch-plate. The engagement between the hammer and catch plate is of course made very slight, so that if the window is raised but a. slight fraction of an inch, a thirtysecond of an inch beingamply sufficient to hold it, the hammer is released and explodes the cartridge. In Fig. 3 I have shown exactly the same device as in Figs. 1 and 2 applied to a door.
l17 denotes the casing, and 18 the door, which of course swings from the opposite side, the hinges not being shown.
The alarm is secured to the casing and the catch=plate to the door, a lip or flange, 19, on the catch-plate projecting slightly over the casing and being engaged by lip 2O upon the hammer.
door is opened slightly to allow lip 20 to pass under lip 19. The door is then closed, the hammer being held at itsretracted position by the engagement of lips 19r and 20, as clearly shown in Fig. 3. As these lips are made narrow, but very slight opening of the door is suf- To set the device when applied to a door, the 9D IOO iicient to release the hammer and explode the cartridge. The form illustrated in Fig. 4 differs but slightly from that illustrated in the other figures. The shape of the catch-plate is changed and lip 2O on the hammer is placed at the lower end thereof nearthe upward opening, instead ol` at the top, as in the other form. The operation ofthe two forms is precisely the same.
It will of eonrse bo understood that the details of construction are subjectto considerable Variation without departing from the spirit of my invention.
I claim-- 1. In a burglaralarln, the combination, with the pivoted hammer, aetuating-spring,and eartridge-holder, of a hase-plate sulaporting the hammer and having llanges, the one parallel to the movement ol' the hammer and the other at right angles thereto, cach ilange having sclewholes, whereby the device is adaptedto be secured in the positions described and to he operated in connection with a suitable stop, as Set forth.
2. In a burglar-alarm, the combination,V with the angled hase-plate7 spring, and cartridgeholder, of the hammer having the lateral pro jection 16 and a projection extending to the rear of the Vertical plane of the pivot, and a stop having a hase-plate and a lip adapted to engage the projections of the hammer from the side or rear, substantial] y as set forth.
3. In aburglar-alarm, the eo1nbination,\vith a easing, o1" the base-plate secured thereto and having the cartridge-holder and ears S, the Y hammer pivoted in said ears and adapted in retracted position to stand parallel with said easing, and the stop secured to the movable part or window and adapted to be engaged with and disengaged from the hammer by heing moved in lines parallel therewith, substantially as set forth.
In testimony whereofl al'lix my signa/tu re in presence of two witnesses.
