IMPROVEMENT IN CALL'BElLLS AND CASTER'STANDS.

The Schedule referred to in these Letten Patent andmaking part o! the same.

To all whom it may concer-n:

Be it known that I, FREDEEIcK ANTON BLT- TERLIEN, of West Meriden, in the county of New Haven and` State of Connecticut, haveA invented a new and improved Call-Bell and Caster-Stand, com= bined'; and I do hereby declare the following to be a full, clear, and exact description thereof, which will enable those skilled in the art to make and 'use the same, reference being had to the accompanying draw- -ing forming part of this speciiication, which'. drawing represents a vertical central section of my invention.

This invention consists in -the arrangement of a toothed rack on the inner end of the touch-rod which projects up through the center of the bell, in combination with a pinion which gears in said rack, and from which extends the rod carryingr the clapper in such a manner that by depressing the touch-rod the pinion is caused to revolve and the clapper is thrown in contact with the bell, and when said touch-redis released the weight of the clapper causes the pinion to revolve in the opposite direction, and the touch-rod, with its raeldare carried back to their original position.

A suitable guide-roller keeps the rack of the touchrod in gear with the clapper-pinion.

.The invention consists, also, in the arrangement of a call-bell in the hollow part of a caster-stand, the touch-rod of said bell extending up through the handle of the caster-stand and acting on the clapper or clappers of the bell in such a manner that the bell is entirely concealed, and that the same does not interfere With the revolving motion of the frame containing the caster. i,

In the drawingy The letter A designates a bell which is `supported on the stand B, as shown.

Through the center of the bell rises the tonch-rod C, and to Athe inner end of this Atouch-rod is attached a toothed rack, a, Vwhich gears in a pinion, i), mounted on a pin secured ifi the stand B.

From said pinion extends a rod, c, tothe end oi which is secured the clapper d.

A roller, b', which bears'on the edge of the rack opposite to the pinion b, sel-vesto keep said rack in gear with the pinion.

' This roller is mounted on a pin secured in the stand B, and, if desired, it may also be provided with cogs, to gear in corresponding cogs on the edge of the rack, so that this second clapper will be operated simultaneously with the clapper (l.

A shoulder, c, above the rack c, prevents the touchrod from rising beyond the desired point.

By depressing the touch-rod C the clapper is thrown in contact with the bell, and when the touch-rod is released it is carried back to its original position by the weight of the clapper.'

By. these means a mechanism for operating callbells is obtained which is very simple and cheap, all its parts being so constructed that they can be cast and pnt together with little trouble or loss of time.

If the stand of the call-bell is constructed with a revolving caster-frame, D, the touch-rod C extends up through the handle ot' said stand, and the mechanism required for sounding the bell does not intel'- fere with the revolving motion of said caster-frame, and at the same time the bell is entirely concealed under the casterstand.

What .il claim as new, and desire to secure by Letters Patent, is

The rack a, secured to the touch-rod C, and gearing in a pinion, 11, which carries .the clapper d in combination with a bell, A, mounted on a stand, B, with or without the' revolving frame D, substantially as shown and described.
