Letters Patent No. 109,952, dated December 6,1870.
IMPROVEMENT IN POCKETALARMS'.
The Schedule referred to in these Letters Patent and making `parl: of the same.
I, CALVIN W. SI-Monns, of Boscawen, in the county of Merrimack, and State of New Hampshire,
have invented a new and useful Pocket-Alarm, of
which the following is a specification.
Nat're and Objects of the Invention.
The object of my invent-ion is-to provide a convenient and eective device for preventing the surreptitions removal or abstraction of any given article froml the pocket of a person without his knowledge.
My pocket-alarm is composed ot a flat case,
adapted to' be sewed to the pocket, and a headed wire or shackle, for attachment to the ypocket-book or pther article to be secured.A *The case contains agongehell and striking mechanism, the latter adapted to be operated only by thewithdrawal of the headed wire.
The owner is enabled to retract the article without sounding the alarm by a brake, the knob of which is located at the lower edge of th case,' so as-to be in' the extreme bottom of the pocket.
Description of the Accompanying Drawing.
Figure 1 is a. front elevation of the complete device, showing, in. dotted lines, a pocketbook or porte'- monnaie attached to the shackle.
Figure 2 is a front elevation of the case and shackle, the cap of the former being removed.
Figure 3 is an inner side elevation of the cap of the case and its appurtenances.
Figure 4 is an edge view of the completedevice, the case and its appurtenances being shown in longitudinal section, on the line z z', fig. 2.
Like letters of reference indicate corresponding parts in the several figures. v
General Description.
A to form a perforated marginal ilange by which to` sew it to the pocket.
l5 is a gong-bell, and
G, a pillar, projecting from the back a of the case A, supporting the same concentrically within said case,
. being riveted to each.
D represents a spring hammer,attached by rivet to the back a of the case A, g being the head of the same, and h a rigid arm, extending axially within the mouth c of the said case, and terminating in an extended head, fi, and a spring jaw, j,- to form, with the rigid jaw lel in said mouth, a catch. v
E represents a spring brake, attached by rivelato the cap b of the case A, k, being the head of the same, @which may be of lead,) and la knob, extending through a-hole in said cap and riveted to said brake, for operating the same.
m is a guard-lip, on tlie outer side ot' the capb of the/'case A, immediately below the brake-knob l, to prevent anything from vgett-ing under said knob and rendering it inoperative.
'A F represents a wireor shackle, having soldered on one end a perforated plate, n, by which it may be sewed -or tied to a pocket-book, G, or other article, and on its other end a cylindricalhead, o', adapted to engage with the catch Il j in the mouth c, and to .be
both inserted and withdrawn by pressure. l
The details of construction are obviously variable, and are non-essential. l
The several parts may all be made'of metal, but other material may be employed for some of them.
I proposegsubstituting a perforatedange proper for the bent-wire f on the case A; also a piy'oted transverse spring catch or tongue in the mouth c, connected by a link with the hammer D, and a hook on the lower end of the shackle F, to engage with said tongue for the means shown for retaining said shackle and lifting the hammer by its withdrawal; also substituting pivoted arms, with rubber or other springs,
Vfor the spring arms of the hammer D and brake E;
also arranging the hammer D under or within the bell, and dispensing with the brake E.
Operation.
lhe operation ot the device, as represented', is as follows:
A ngcr of the hand, grasping the pocket-hook, guides the head o of' the shackle F into the mouth c ot' the case A, where, pressing back the spring-jaw j of the catch al j, it' engages behind the same, and is held from accidental withdrawal, the head limiting its insertion. The pocket-book can now only be withdrawn by forcing the head o ont through the catch d j, which action, through the arm h, lifts the hammer D and trips ,the same, causing it, by its resiliency, to str ike the bell, and thereby sound au alarm, unless the vibrations of the bell be stopped by applying the brake E, access to th'e knob l of which could not he had without the owners knowledge.
By using this brake the owner may'himself readily withdraw the article without noise.
C lm'ms.
