PNEUMATIC BELL.
SPECIFICATION forming part of Letters Patent No. 357,699, dated February 1,5, 1887.
Application filed April 22, 1886.
Improvements in Pneumatic Bells, of which.
the following is a specification.
My invention'relates to bells used as doorbells and for other similar purposes, and which IO are operated by the motion of a column of air through a small pipe; and the object Of my invention is to provide a cheap and simple device wherein the air is compressed or set in motion by means of a piston in a cylinder.
I This Object I attain by the mechanism illustrated in the accompanying drawings, where- 1n- Figure 1 is a sectional view of the device. Fig. 2 is a detail.
2O A is a cylinder; B, a piston working therein; G, a cap thereon,having a central aperture, through which reciprocates the push button D, attached to the piston.
C is a hole in the piston.
E is a spiral spring in the cylinder in front of the piston.
F is a pipe of suitable size and material.
G is a smaller cylinder, having the piston H, and the spring E', and connected with the other` 3o cylinder by the pipe or tube F.
I is arack pivoted to the end of piston H and engaging the pinion M.
J is a cog-wheel tight on the shaft X, and carrying the dog L and spring K. The dog` bears against the ratchet-wheel M, and when the same is moved in onerdirection causes the cogwheel J to rotate Vwith it.
N is an escapementfleverattached rigidly to the hammer O a-nd pivoted on the frame U.
4o P is a bed which supports the frame U and the cylindersupport S and bellsupport T.
R is the bell,
Visa spring attached to .the outer end of the frame U, and which bears against the rack I and holds it against the pinion.
Serial No. 199,748. (No molel.)
M and M are rigidly secured together and loose on the shaft X, while the wheel J is tight thereon.
The use and operation are as follows: The push button or buttons are placed in suitable 5o position, as in a doorframe, where they` may be so ixed as that the button will be visible on the Outside ofthe house and the pipe F will connect within. The bell Or bells are then placed in position where they are designed to be used, as in the kitchen Or hall. The cylinders are then connected bythe pipe'F. When pressure is applied, it is transmitted from the `push-button to the rack and pinion, and thence to the cog-w-heel. The escapement-lever is 6o .thereby agitated and rocked, so as to give a series of blows on the bell. The bell will not ring as the piston retreats, because the gear is tight on the shaft and the pinion loose thereon.
The pistons are assisted in returning to their places by the spiral springs. When the linger is removed from the push the wind will escape through the hole. This hole is not necessary in all cases.
1. In a pneumatic bell, the combination of the sounding-bell and its piston, a connecting pipe and a push or actuating cylinder provided with a cup-shaped piston, a hollow cylindrical thumb-piece secured thereto, and a reactng'spring which rests in the actuatingcylinder and projects into the hollow thumbpiece and bears against the end Ot' the cylinder, as shown and described.
2. In a pneumatic bell, the combination of' 8O p the sounding mechanism and connecting-pipe with a cylinder, piston, and push-button, the latter being perforated, so as to leave the space in the cylinder on the inside of the piston connected with the outer air when the thumb is removed.
