RAIN SIGNAL.

'Applicationfiled July 2, 1920.. Serial 1511393301.

To all whom it may concern:

Be it known that ANTON A. LIBERA, a citizen of the United States of America, residing at Thorndike, in the county offlampden and State of Massachusetts, has invented certain new and useful Improvements in Rain Signals, of whichthe following is a specification.

This invention relates to improvements in rain signals and its leading object is to pro-,

vide a rain signal including an audible alarm and a breakable strip normally retained'under tension to hold the alarm inoperative and adapted to beweakened by the deposit'of rain thereon, to permit of the operation of the alarm at the time of the fall of the rain.

Another object of the invention is to provide'improved means for holding thebreak able strip under tension and means co-operating-therewith to release the alarm mecha- Another object oft-he invention is to provide a support capable of adjustably hold-- ing the devicein various angular and spaced relations to a window sill. lVith the above and other objects in view the invention relatesto new. and useful improvements, combinations, and arrangement of parts clearly described in the following specification and fully illustrated in theaccompanying drawings, in which:

Figure 1 is a side elevation.

Figure 2 is an end view.

Figure 3 is a top plan view.

Figure 4 is a' longitudinal sectional View. Figure 5"is a detailed view showing the automatic trip for releasing the signal retaining lever. v i

Referring to the accompanying drawings 5 designates a case comprising a housing 6 for the signal and the actuating mechanism therefor and a housing 7 adapted to contain a roll of breakable paper orthe like and means for limiting the unrolling of the paper whereby the paper can be maintained under tension, the housing 6 being connected to the housing 7 by means of downwardly offset bridge piece or connection 8.

In the housing 7 a supply roll 9 is mounted upon a shaft 10 which is journalled on the sides of the case 5 and carries on one end a crank 11. The roll 9 is engaged by a brake shoe or the like 12 which is carried by the arms 13 and 14 pivotally mounted upon the shaft 15 journal led on the sides of the housing 7. The shoe 12 is held under tension against thejroll- 9 by means of a spring-1 6.5 i

mounted upon the-shaft 15- and arranged to maintain tension against the arms13 and. 14; The shoe 12 is disengaged from the roll,

9 by means of a lever 17 pivotally connected at 18 to said shoe and provided with a pin 19 having sliding connection in a slot'20 of the arm 2l fiXed ing 7. s 1

to the shelf 22 of the hous- The web or strip 23 from'the roll 9 is e x tend'edacross-the connecting or bridge piece 8 andis,grippedbetweenthe lower jaw 24' and the upper j aw 25 of a clamp carried by the spring propel-led slide26. The upper j aw. 25 is mounted upon the side bars 27 pivotally supported by the-shaft 28 carriedthe slidingbase 26. The shaft-28 carries a spiral spr1ng wh1ch.ma1nta1ns tension against' a lever 29 having connection atone-end with the upper jaw 25 and a fulcrum uponthebar; 7 30 connected with the side bars'27'. By de. pressing the terminal 29? the upper jaw'25 .may be elevated above the lower the web 23 secured there between. I v The base 26 is mounted to slide on' horij aw: 24; and

zontal guides 31 provided on opposite sides of i the housing 6 and is propelled by means of a spring 32 which is secured at'oneend at 33 and at the other end engaging alever-34 which is pivoted at 35 to the .housing"6. and is pivotally connected with .thelink 36 which link is pivotally connected with the upright lever 37% 38 and the'leverf37is pivotally connected at 39 with a'lug '40 provided'onthe under side of the sliding base 26.

In thehousing 6 a clock spring mechanism of any suitable type is arranged, the main shaft' 41 OfvWlliCh extendsthrough'thesides of theihousingand is adapted-to carry the winding key '42. The clock spring mechanism is adapted to operate a'Vibrating.ham-.

mer 43 which is adapted to strikeagainst the bells or gongs or audible sounding means 44' supported upon the upright posts 45 carried by the shelf 46 arranged within the housing 6. The mechanism by which a hammer 43 is vibrated may be-of any desired type, such as that as is used in alarm clock constructions.

The vibrating hammer 43 is mounted upon a shaft which is equipped with the usual stop arm and this stop. arm is adapted to be engaged by a pin 48 carried by alever 49 pivotally supported upon the shaft 50 which shaft is supported at its ends on the housing 6 An abutment plate 51 is connectedto the lower end of the lever 49 and a lever 52 is pivotally connected at 53 with the lower end of the lever 49 and extends upwardly and has connection at 54 with the lever 55 which is pivoted at 56 to the shelf 45 by means of a lug or the like 57 carried by said shelf.

The lever 55 carries a weight 58 on one endthereof and is provided with a slot 59 in which the upper end of the lever 49 works I the fall of rain water thereon and said web breaks under the tension maintained by the spring 32 the arm 62 will strike against theabutment plate 51 and the lever 49 will be moved away from the stop arm 47 so as to disengage the stop pin 48 from said arm 47 and the hammer 43 will be released to vibrate. under the automatic action of the alarm spring mechanism contained in the housing 6. When it is desired to lock the hammer 43 against movement the shaft 63 which'carries the crank arm 64 may be rotated so that the crank arm 64 will engage the hammer 43 and prevent vibratory move ment thereof.

It will be seen that when the-web 23 is maintained under tension by the propelling spring 32 and said paper web or the like is weakened by rain water so that the tension of the spring 32 will break said web the striker arm 62 will be propelled by the action of the spring 32 so as to abut against the plate 51 and disengage the stop pin 48 fromthe arm 47 so that the hammer will be released to vibrate under the actionof the spring mechanism until manually stopped by operating the shaft 63 by means of its crank 63 The mechanism contained in the housing 6 is protected by means of a swinging cover 65 and the mechanism contained in the housing 7 isprotected by aswinging cover 66. r

The case 5 is provided with depending brackets 67 which are pivotally secured to the upstanding brackets 68 carried by the vframe 69. The frame 69 comprises parallel spaced plates each of which is formed with a slot 70, the two slots being disposed in alignment. Between. the plates 69 the head 71 of a clamp member 72 is adapted to slide,

said head being formed with outwardly proj ecting lugs 73 which slidably extend through the slot 70. The clamp member 72 carries a clamping screw 74 which is adapted to engage the shank 75 of the clamp member 76, which is equipped with a screw 77. The device is clamped between the head 77 of the bracketscrew 77 and the jaw of the member 74, as shown in Figure 1. this relation the frame69 maybe slidably shifted upon the lugs 73 or'the case 6 ad j usted to various angular relations by reason of the pivotal connection between the bracket 67 and 68. This angular adj ustment may be varied at will by means of the screws 78 and 79 which are pivotally secured at their ends to the brackets 80 and 81 carried by the case 5 and the frame 69'respectively. The confronting ends of the screws 78 and 79 are provided with right and left screw threads and are engaged by the turnbuckle'82, the manipulation of which will adjust the case 5 at various angular relations upon the brackets 67 and 68.

- Having described myinvention I claim 1. A rain signal'comprising a case having a'roll therein, an absorbent rupturable strip on the roller and extendable therefrom, means :for retarding the rotation of the roll, means for holdingsaid strip under tension slidable on said case, and a signal adapted to be actuated by said means onthe rupture of said strip. i i

2. A rain signal comprising a case, an audible signal therein, a member slidable on the case and having means to actuate the signal, said member being provided with a gripper means for holding said member under tension, a fabric strip adapted to be clamped by said gripper, a roll for said strip, and a tension device for said roll, said case being provided witha gap across the said a strip to receive rain drops. 1
