CLOCK-BELL.

SPECIFICATION forming part of Letters Patent No. 600,705, dated March 15, 1898.

Application filed September 18, 1895. Serial No. 562,882. (No model.)

To all whom t may concern.; the alarm-spring, with a key-opening A'i for Be itknownthat I, ARCHIBALD BANNATYNE, the insertion of a key for setting the alarm of Vaterbury, in the county of New I'Iaven mechanism, and with a key-opening A5 for and State of Connecticut, have invented a new the insertion of a key for regulating the alarm 5 5 Improvement in Rear-lVinding Clocks; and mechanism. The said key-openings A2, A3,

The number and position of the on, to be a full, clear, and exact description of key-openings in the bell will of course depend 6o 1o the same, and which said drawingsconstitute upon the construction of the time-movement part of this specification, and represent, in employed and the character of the clock. The Figure 1, a partial View, in vertical central said bell is nearly as large in diameter as and section, of a clock containing my invention; arranged concentric with the circular clock- Fig. 2, a view thereof in rear elevation; Figs. case B, which may be of any approved con- I5 3 and 4i, partial views, in vertical central secstruction and which is provided with a removtion, showing other ways of attaching the able circular back B', which may also be of clock-bell to the rear movement-plate of the any approved construction and secured in time-movement of the clock. place in any approved manner. The edge of My invention relates to an improvementin the iiange A/ of the bell comes quite close to 7o 2o clocks having small cylindrical cases and prothe outer face of the back B. For the reason vided with bells, the object being to produce that the bell is of relatively large diameter as a simple, cheap, and effective clock of neat compared with the size of the case a powerappearance and constructed with particular ful bell, and hence a strong alarm, is secured reference to locating a relatively large bell to for a clock of comparatively small size.

I do not, however, limit myself to the use of a hub for connecting the bell with the rear movement-plate of the time-movement, for the bell may be otherwise connected with the rear movement-plate. Thus in Fig. 3 the bell G is secured to the rear movement-plate II by means of two posts I I, which extend rearward through the back J of the case J In this construction an opening G is formed in the center of the bell for access to the squared rear end of the center arbor II. In the construction shown by Fi. et a stirruplike frame L is employed for securing the bell M to the rear movement-plate N, the inner ends of the said stirrup passing through the back O of the cylindrical case O'. In this construction an opening ll/ is formed in the center of the bell and an opening L in the outer portion of the stirrup for the access of a hand-setting key to the center arbor of the time-movement.

In the constructions shown by Figs. 3 and l the openings formed in the body of the bell for the insertion of keys for winding the time and alarm springs and setting and regulating the alarm are not shown; but it will be understood that the bells are formed with such openings as are required for access to the winding and setting arbors of the movement.

In view of the modifications suggested and of others which may obviously be made I would have it understood that I do not limit myself to the exact construction herein shown, but hold myself at liberty to make such changes as fairly fall within the spirit and scope of my invention.

lfIaving fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a rear-winding clock, the combination with a case having a back, of a movementframe located within the said case, a bell arranged concentrically with and at the rear of the said back of the case, and having its central or body portion formed with one or more key-openings, and means connected with the rear plate of the movement-frame and extending through the said back of the case and into the interior of the bell for connecting the same with the said rear plate of the movement-frame, whereby a relatively large bell may be located at the back of the case and access had to the winding arbor or arbors of the clock-movement through the central or body portion of the bell itself, and whereby also the bell is supported by the movementframe by means located within the case and bell.

2. In a rear-winding clock, thc combination with a case having a back, of a movementframe located within the said case, a bell arranged concentrically with and at the rear of the back of the said case, and having one or more key-openings formed in its central or body portion, and a hub-like post passing through the back of the case, secured by its inner end to the said movement-frame, having the said bell secured to its outer end, forming a bearing for the rear end of the center arbor of the clock-movement, and provided with a longitudinal passage through which access is had to the said arbor for setting the clock.

3. Ina rear-windin g clock, the combination with a cylindrical case having a back, of a movement-frame located within the said case, a bell arranged con ccntrically with and at the rear of the back of the said case and having one or more key-openings formed in its central or body portion the center of which is set inward to form a clearance-recess, a hub-like post passing through the said back, secured at its inner end to the rear plate ol the movement-frame, forming a bearing for the inner end of the center arbor of the clock-movement provided with a longitudinal passage for access to the rear end of the said arbor for turning the same in setting the clock, and having the said bell mounted upon its outer end, which extends into the bottom of the said central recess of the bell, and a nut located in the bottom of the said recess and screwed upon the projecting outer end of the hub which is thereto threaded, the nut serving to secure the bell to the hub.

4. In arear-winding clock, the combination with a cylindrical case, of an independentlyformed disk-shaped back, a movement-frame located within the case, a bell arranged concentrically with and at the back of the said case, and having one or more key-openings formed in it, and means for connecting the bell through the said disk-shaped back with the said clock-movement, whereby a relatively large bell may be located at the back of a cylindrical rear-winding clock, and access had to the winding arbor or arbors of the clock-movement through the bell itself.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
