PNEUMATIQ BELL-RiNclNe.
SPECIFICATION formingpart of Letters Patent No. 268,88-2, dated December 12, 1882.
" Application filed September 16, 1882. (No model.)
.To all whom it may concern.-
Beit known that I, ROBERT P. GARsED, a citizen ofthe United States, and a resident of Norristown, in the' county of' Montgomery and State of Pennsylvania, have invented a new and useful Improvement in Pneumatic Door- Bells or Alarms, of which the following is a specification.
The object of my invention is to furnish a pneumatic door-bell in which one pull of the bell-knob will cause the bell to ring a number oftimes; and l accomplish this object by the mechanism illustrated in the accompanying drawings, in which- 4' Figure lis a side View of my invention; Fig. 2, an enlarged side View of the pump and plun ger Fig. 3, a sectional view of' the same 5 Fig. 4, a back view of the same; Fig. 5, aside view of the winding-spring; Fig. 6, a side view of' the hammer and its operatingwheel, and Fig. 7 a side View ofthe collapsible bellows.
My air-pump A is represented in the drawings as a hollow rubber ball or sphere; but it may in practice have any other suitable shape, and is operated by a plunger, B. The pump A is situated in ametallic hemisphere, C, which is bolted securely to the inside of the doorframe, and it has an orifice, D, in its end, through which the compressed air passes in order to operate my mechanism. The plunger is situated upon aframe-work, F, to which the bell-pull is attached, and this frame-work in the drawings is represented as being attached to a plate 0, to which the bell-pull is fastened; but if more convenient the guide-rods 'F may be twisted or soldered together to forman eye. The guide-rods F pass through slots in the rim or flange of' the hemisphere, and may be adjusted without detaching the plunger B, and they are `surrounded with spiral springs S, whose office is to assist in returning the plun Attached to the inner side of the flange of the hemispherical cup G, and at a suitable distance fronrand partly surrounding the guides, are fenders R, whose of'- tice is to keep the rubber pump from rubbing against the rods F and springs S.
ln the center of the plunger, and directly opposite the orifice D inthe pump, a pipe, E, is placed, through which the compressed air passes to a bellows, G, and, in order to allow the plunger B to operate, a part-,1), of this pipe is flexible or telescopic.
On top of the bellows G is a staple, H, between the legs of which a shaft, I, passes, upon one end of which lis atoothed wheel,K, and upon the other a spring, M rllhe teeth of' the wheel K engage with and operate the escapement L, upon which the striking-hammer of' the bell is placed. The spring M has one end securely fastened to the shaft l, and the other is secured to some convenient fixed place.
From the top of the staple H a cord or band, N, is suspended, which pas-ses around and is secured to the shaft-I.. v
The operation of' the device is as follows:
The bell-pull being drawn out, the plunger B v is forced into the rubber sphere A, compressing the air therein, which passes through the oriiice D and pipe E to the bellows G, raising this bellows and the staple on its top and uu- Y winding the band or tape N, which,passes around theshaft I. The unwinding of this band causes the shaft 1 to be rapidly revolved, and with it the toothed wheel K, the teeth of which engage `with the escapement L, and cause the hammer to give the bell a number of' rapid strokes. Instead ofthe toothed wheel and arm, there may be a number of hammers radiating from andattached directly to the shaft l by means of flexible arms, and the -rotation of the shaft would cause these hammers tostrike the bell successively. When the shaft is revolved, in order to operate the striking mechanism, the 'spring M is wound up, and when the air in the bellows G escapes the spring unwinds itselfand revolves the shaft in the opposite direction, and winds up the` tape N, and the device is again in acondition to be operated. i
It will be seen that the coil-spring N, by attachment tothe shaft I, will collapse bellows G through the medium of a rack upon said bellows engaging with a pinion upon said shaft.
Having thus described my invention, I claim and desire to secure by Letters Patentl. The combination, in a door-bell pump, of the perforate iieXible sphere A, supported by the metal holder C, and with operating-plunger B, said plunger being attached` to a pull, and havingan orificeinits centerfor the passage of air, and attachment to the pipe E through IOO 9. QGSS! the liexible or telescopic tubing P, and said flexible or telescopic tubing P, the Whole adapted for ringing a bell, substantially as shown and described.
2. As a means for operating a d.oorbell,and in combination with adevice for pneumatically operating the bellows G, the bellowscarrying a staple, H, and the band N, one end of which is attached to said staple, and the other wound around the shaft I to revolve said shaft and to operate the hammer, substantially as shown and described.
3. As a means for collapsing the bellows Gr, and adapted to be'wonnd up by the expansion of said bellows, the spring M,one end ot' which is attached to the shaft I and the other to v some fixed point, in combination with the tape 4. In a pump composed of the holder C, cov
erin g A, and plunger B, the latter attached to. rods connected to a bell-pull and passing through a tlange on said holder, the combination,with said rods and guide-flan ge, (the latter adapted to receive the bearing of the sprngs,) the springs S, surrounding said rods, and the fenders R, fastened to the guide-ange, the springs adapted to return the plunger to its position when not actuated by the bell-pull, and the fenders to prevent said springs or rods from rubbing against the rubber sphere, the whole operating substantially as shown and described, as and for the purposes set forth.
R. P. eARsED.
