.To a/ZZ whom it may concern.-
Be it known that I, GEORGE D. WINTERS,
Reno, in the county of. Vashoeand State of` Nevada, have invented certain new and useful Improvements in Barricade-Alarms for Doors, of which the following is a full, clear, and exact description. x
My invention is an improvement in burglar-alarms, beingin the nature of a barri cade-alarm for doors, whereby an alarm will be sounded by a partial opening of the door in case any one should attempt to enter when the alarm is set.
The invention consists in certain novel constructions and combinations of parts, as will be hereinafter described, and pointed out in the claims. In the drawings, Figure l is a perspective view showin gthe lower portion of a door with myimprovements applied. Fig. 2 is a detail elevatiompartly in section,showin g the alarm mechanism, the bell being removed. Fig. 3 is a side view of the alarm mechanism. Fig. 4 is a top plan view thereof. Fig. 5 is a de tail section o`n about line 5 5, Fig. 2. Fig. 6 is a detail View showing the lower portion of the strut-bar and the seat-plate therefor, and Fig. 7 is a detail view of the seat-plate.
In carrying ont my invention I prefer to provide the seat-plate A for the lower end of the strut-bar B,such seat-plate being recessed in the floor and having a socket A for the bolt B' at the lower end of said bar. While this seat-plate is preferred, it will be understood it may be omitted when desired and the bar be pointed or otherwise adapted at its lower end to engage the iioor. At its upper end the strut-bar B has `a sliding connection with the door,being preferablyprovided with a lon gitudinally-elongated slot B2, through which is passed the bolt C, bywhich the strutbar is held to the door. This bolt C is supported by lugs or brackets C' on a frameplate C2, which also supports the bell D and the mechanism for sounding the same, which mechanism includes a trip-bar E, arranged for operation by the upper end of the strutbar and adapted to release the detent which `with its lowerend as a pivot.
holds the bell from sounding. The alarm mechanism, as shown in Fig. .1,.is supported on the door. This bar Eextends above the upper end of the strut-bar, and the latter as it moves `upward by` the openingV of the door will press the bar E up and causeithe same to release the detent and permit the'bell to sound, as will more fully appear hereinafter. In `this operation itwill be seen that the door. is opened it will push the upper end of the strut-bar back and the latter 'will,\rise, owing to its movement in the arcfof a circle As it so rises it will lift the bar E 'andA release Vthe alarm mechanism, which I willnow describe.
The bell is4 sounded by a spring F,`con
`nected with a ratchet pF', which is rengaged by a detent-pawl G, pivoted at G andarranged to be engaged by a projection E on the bar E in such manner as to be released by the upward movement of the strut-bar, as before described. The operation of this construction will be well understood from Fig. 2. As the strut-bar is lifted it willthus release the detent, and the bell will sound; 'but if the door shouldbe slightly opened andthen quickly closed the bell would sound momentarily except for the detent H, which I have provided for holding the bar E elevated when it is pushedfup by the strut-bar. As lshown in Fig. 5, this detent is in the form of ahook pivoted at its upper end and arrangedat its lower end to engage' underA the bar E when such bar is lifted by the strut-bar.' This detent thus holds the bar E up and causes the bell to sound until it is run down or until the detent I-I isreleased, so if one should attempt to enter the room and should quickly close the door aftery the bell commences to sound the bell will not stop ringing, but will con.`
tinue ringinguntil run down.
When the strut-bar is not in use, it may be swung upward on the bolt C` as a pivot and be held by engaging its bolt B with an eye or staple I on the door.
Having thus described my invention,what I claim, and desire to secure by Letters Patent, is
l. A barricade-alarm for doors comprising a strut-bar having at its upper end a sliding connection with the door and an alarm mechroo anism supported on the door and 'including p ing the trip-bar substantially as sei forth.
3. In an apparatus substantially as described the combination of the door, a strutbar having at its upper end a sliding connection with said door and the alarm supported independently of the strut-bar and having a trip portion arranged to be released by said.
strut-bar substantially as described.
4. A barrieade-alarm for doors comprising a frame-plate supporting the alarm mechanism and provided with brackets, a strut-bar having a longitudinally-elongated slot and fitted between said brackets, the pin or bolt passed through said slot whereby the strutbar has a sliding connection with the frameplate, and the alarm mechanism having a trip portion arranged for operation by the strutbar substantially as described.
5. A barricade-alarm for doors comprising the bell, the spring for sounding the bell, the detent-pawl for restraining said spring, the trip-bar arranged at one end to release said detent-pawl, the strut-bar for operating said trip-bar to release the detent-pawl, and a detent for holding said trip-bar when adjusted by the strut-bar substantially as set forth.
6. In an alarm mechanism the combination of the strut-bar having at its upper end a sliding connection with the door, alarm mechanism arranged to be released by such upper en'd of the strut-bar, and a seat-plate to receive the lower end of the strut-bar substantially as set forth.
7. A barricade-alarm for doors, comprising the door, the strut-bar, the alarm mechanism arranged for operation by the strut-bar, a seat-plate in the iioor, an eye or staple on the door and a bolt at the swinging end of the strut-bar arranged to engage the seat-plate when the strut-barislowered and the eye or staple when the strut-bar is raised substantially as set forth.
