sPncImcA'rI'oN forming part of neets'ratenenra venoso, dated May 13, 1902. Application filed September 16,1901.' Serial No. 75,450.' (No model.)
To @ZZ whom it may concern:
Be it known that we, LUCIEN H i HANDY, residing in the cityfand Vcounty of SanFrancisco, and CHARLES S. HosnoRD, residing at Berkeley, county of-Alameda, State of California, citizens of the United States, have in-f rangement, and combination of parts, whichV we shall hereinafter fully describe and which have for their object the provision of an inexpensive, portable, and effective device for giving security to occupants ofrooms the doors of which are inadequately provided with fastenings.
Referring to the-accompanying drawings,
Figure 1 is a view of .ourv device, showing it applied to a door. Fig-2 is a back View of the device. 'Fig. 3 is a front view of same, a portion of the bell being broken away. Fig. L is a View of the holder-plate A.
A is a metal plateior stock which may be termed the holden It is provided at one len'd'with the holding-points a, turned at right" vangles to the plate, and on the opposite side it has a spring ct of suitable character, best formed asa tongue integral with the plate. The other end of theY plate or holder is formed with an open-ended slot a2. v y
B is the base-plate of the alarm mechanism.' It has its forward end turned sidewise to form a stop o, and it is provided with a screw-stud b', which slips into the slot a2 yof the holderplate. A thumb-nut C, fitted on the stud b', serves to tighten the base-plate B upon and to hold it to the holder-plateA in the position and with the firmness required.
Carried by the base-plate B are the bell D and the frame E of a suitable clockwork alarm mechanism. This mechanism it is unnecessary herein to show, as it forms no part in ,detail of 'our invention.
fing.
Its construction ,beingI that of the ordinary alarm mechanism, it need not be specifically described in order vto fully understand ourinvention. It is suf- 'iicient to' say that it consistsofthe usual spring-operated gearing actuating a striker 4 c2 andput under tension by a Winding-key,
such asis Aindicated at e, the striker being vibrated bythe usual escapement. From the Istriker projects a pin e", which when held arrests the alarm mechanism.
' Mounted'and adapted to, have ka sliding movement longitudinallyin the base-plate B isa tripping-rod F. Its forward end passes through and projects beyond the stop l) of said base-plate. It has a shoulder f formed upon it, which when the rod is normally pushed forward or projected engages the pin e' of the striker e2` of the alarm` mechanism and by preventing its Vvibration stops the operation of vsaid mechanism. .A spring Gr bearing on the tripping-rod serves to` hold it projected against the spring-power of the alarm mechanism, which through the' pin Ie' tends to withdrawor force it back.
The operation of the device is as follows: H is a door, and I is the stile of the door-casing. The stock or holder-plate A (the baseplate B, with its alarm mechanism and tripping-rod, beingpreviously removed) is fitted to thecasing-stile I by pressing the holdingplate is temporarily supported in a horizontal position projecting inwardly from the casrIhenthe door is closed, and its edge bearingka'gainst plate A will force it firmly in place, the spring-tongue-ct servingv to take lupslaclgthus providing for different spaces existing between the doors `and their casings and holding both itself and the door so firmly that the door will not rattle nor will the holder fall out nor can it' be pushed out from lthe outside, because it is back of {Ythe'stop-bead on the casing-stile. Now the base-'plate B, with its carried parts, is tted upon the holderplate A by slipping its stud b into the openended and exposed slot d2 of said'holder-plate. It is moved along until the projecting end of the tripping-rod F is near to or lightly touches the door, with the stop b just back of it and opposing the door. The open-ended slot enypoints t into the wood, so that ythe holderables these parts to be readily fitted tothe holder-plate, and the elongation of the slot enablesthe tripping-rodand stop tobe brought up to their proper positions, thus compensating for dilerent thicknesses of doors'and regulating them to the adjustment or position of the holder-plate. When the base-plate is properly adjusted, it is firmly fixed in position on the holder-plate by tightening up the thumb-nut C. Then the key e is turned to wind up the alarm mechanism, and the latter, though now under tension, is arrested and held inactive by the striker-pin e being in contact with the shoulder fof the projected tripping-rod. If now the door be forced, the rst eect due to the contact of the door with the tripping-rod F is to push said rod back. This will cause it to withdraw its shoulder from engagement with the striker-pin e, which being now free to vibrate will allow the alarm to sound, and the alarm will continue until run down. The second electis to bring the door up against the stop h of plate B, which thus serves as a lock, keeping the door from being further forced open. The occupant of the room if he desires to hastily investigate the origin of the alarm can by simply giving the thumb-nut a little turn loosen the base-plate B and draw it and its carried parts from the holder out the open-ended slot thereof, thereby releasing the lock and saving time over an operation which would involve an entire removal of the thumb-nut, as would be the case if the slot c2 did not open out at the back of the holder. The springtongue of the holder holds the door firmly enough to prevent it from being moved inwardly by slight causes, such as wind, and by the arrangement of the tripping-rod to permanently release the alarm mechanism the full value of the latter is obtained, insur- V ing notice to the occupant.
Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-

In a burglar-alarm and door-lock, the combination of a holder-plate adapted to be seated between the door-casing and the door edge, and havingin its rearend an open-ended slot, a base-plate having a stud with thumbnut, whereby said plate is adjustably and removably fitted to the slot of said holder-plate, said base-plate carrying an alarm mechanism and having a stop on its forward end opposing the door, a slidable tripping-rod mounted in the base plate with its end extending through the stop and lying in the path of the door movement, and an engagement between said rod and the escapement of the alarm mechanism eective to arrest the operation of the said mechanism when the rod is normallyset and to release said mechanism when the rod is pushed back.
