CLOCK.

SPECIFICATION forming part of Letters Patent No.4 258,421, dated May 23, 1882.

Application tiled December 24, 1881.

To all whom it may concern:

Be it known that I, ARTHUR E. HoroHKIss, of Cheshire, in the county of New Haven and State of Connecticut, have invented `certain new and useful Improvements in Clocks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such us will enable others skilled in the artto which it pertains to make and use the same.

My invention relates to an improvement in clocks, the object being to provide a clock of such construction that it will occupy but little space, and yet be provided with sufticient space for the employment of a mainspring of any desired size'and power; further, to enable the clock to be wound and set without necessitating the removal from the mantel or other support.

gVith these ends `in view my invention consists, first, in aclock, the combination, with a center shaft, of the mainsprin g-arbor arranged vertically inthe clock, and'suitable gearing combining the center shaft and mainspringarbor.

My invention further consists in the combination, with the center shaft of a clock-movement, of a mainspringarbor arranged vertically in the clock, and having a mainspring and Winding device connected therewith.

My invention further consists in the combin'ation, with the center shaft of a clock, ot' a mainspring-arbor arranged vertically in the clock, and a device located on the outside of the movement-frame for setting the hands.

My invention further consists in certain other 'features ofconstruction and combinations ot' parts, as will hereinafter be described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is ya view, in front elevation, of a clock embody- (Model.)

is located 'the trainot wheelsE, which is driven by the center shaft, F, the latter being arranged horizol'itally and projecting through the front plate, C, to allow of the attachment of the hands or pointers of the clock, and extending through the middle plate, B, its rear end being provided with two solid. pinions, c d. Pinion c is attached to a sleeve fastened to the center wheel, e, the latter being secured to the centershaft by frictionalengagement, while the pinion d is rigidly secured to the center shaft.

G is the mainspring-arbor, whichis arranged vertically between the middle and back plates of the frame. The lower end of the arbor G extends through the top plate,f, ofthe cylindrical spring case or box H, situated at the bottom of the movement, and secured thereto by means of screws g, inserted through the lower pillars a and the top plate, f, or in any other desired manner.

To the lower end of the arbor Cr is fastened the niainspring-drum I, provided with a disk, h. The inner end of the mainspring t' is secured to the drum I in the usual manner, which consists in securing a pin or stud to the drum and hooking the inner end of the spring there` upon, while the outer end of the spring is fastened to the spring case or cylinder H.

Encircling the mainspring-arbor G is a sleeve, J, the lower end ot' which has aratchetwheel, j, attached thereto or formed integral therewith. A pawl, 7c, pivoted to the upper face ofthe disk L of the mainspring-drum, engages with the ratchet, and is retained against displacement by means of the sliiring K.

To the upperend of the sleeve J is secured or formed therein a bevel-pinion, L, which meshes with a bevel-pinion, L', secured to the rst wheel, M, or to its shaft. The first wheel, M, meshes with the pinion c and imparts motion thereto, and consequently to the train E. A collar, 1, is fastened to the sleeve J by a screw, l', to retain the arbor in place. A folding handle, J, is attached to the sleeve J, and is used when desired by winding up the spring.

The upper end of thearbor has aknob or any suitable device, M', attached thereto, whereby the clock may be wound without removing it from its support.

Upon the upper portion of the mainspringarbor is placed a sleeve,N, to which is secured a disk, (),preterably constructed with'a down- TOO wardly-projecting lian ge, o, though this flange may be dispensed with. The lower end of the sleeve N is provided with teeth, n, which engage with the pinion d when the sleeve is depressed, and thus by rotating the disk O the center shaft may be turned in either direction for setting the clock. The teeth a on the lower end of sleeve N are retained out of engagement with the pinion d by means of a spiral spring, I), interposed between the disk and the bridge-plate, P', the latter being secured to the back and middle plates.

Instead of using the disk O for setting the clock, the thumb-piece Q at the side of the movement may be employed for this purpose. The thumb-piece Q is attached to a shaft, Q', which is supported to a stationary tubular bearing, R. The inner end of the shaft Q is provided with a pinion, g, which meshes with the pinion d, and hence by turning the thumbpiece Q the hands of the clock can be turned in either direction. A spiral spring, S, serves to throw the pinion q outof engagement with the pinion d.

From the foregoing it will be observed that the different parts of the clock are in small compass, while sufficient space is provided in theiboX or casing for the mainspring for the employment of a thirty-hour or eight-day spring.

The clock may be wound by the winding at tachment connected with the lower end of the mainspring-arbor, or by the device attached to its upper end. When the latter is used the clock may be wound without being removed from the mantel o r other support. The clock may be readily set without opening the case.

Instead of locating the spring at the bottom of the clock, it mightbe located near the upper end.

It is evident thatmany slight changes in the construction and relative arrangement of parts might be resorted to without departing from the spirit of my invention, and hence Ido not limit myself to the exact construction and arrangement of parts shown and described; but,

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

1. In a clock, the combination, with the center shaft and pinion-shafts of the train arranged horizontally and supported in vertical plates, of the mainspring-arbor arranged vertically in the clock, and a mainspring attached to one end thereof, and suitable gearing connecting the mainspring-arbor and center shaft, substantially as set forth.

2. In a clock, the combination, with the eenter shaft and pinion-shafts of the train arranged horizontally and supported in vertical plates, of the mainspring-arbor arranged vertically in the clock, a winding device attached to one end of the mainspring-arbor, and a mainspring connected with its opposite end, substantially as set forth.

3. The combination, with the center shaft and pinion-shafts of the train arranged horizontally and supported in vertical plates, of a mainspring -arbor arranged vertically in the clock and connected by gearing with the center shaft, and devices located on the outside of the movement for setting thehands or pointers, substantially as set forth.
