CLOCK.
SPECIFICATION forming part of Letters Patent No. 408,665, dated. August 6, 1889.
Application filed October 4, 1888.
To all whom it may concern.-
Be it known that we, EDWARD M. MOUL- TON and MARK MOULTON, both of Rochester, in the county of Monroe and State of New York, have invented a certain new and useful Improvement in Clocks; and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the drawings accompanying this ap- IO plieation.
The object of this invention is to so connect the mainspring and mainspring-wheel that said parts may he detached for repairs and applied again without taking the movement t 5 apart or disturbing the other gearing. In general principle it is similar to that patented by us September 18,1888, No. 389,852,asleeve fitting between the side plates of the frame and an arbor passing through the sleeve being used as in that case.
The special object in this invention is to make a loose connection between the sleeve and arbor; in other words, to avoid the use of screw-threads, which necessitate anumber of turns of the arbor in the sleeve to connect the parts immovably together.
To this end the invention consists of a sleeve having its interior square or of equivalent form in cross-section, an arbor of similar form passing loosely through the sleeve, and a suitable fastening device for securing the parts together, all. as hereinafter more fully described.
In the drawings, Figure 1 is an edge eleva- 3 5 tion of a portion of the clock-frame, showing the mainspring, mainspring-wheel, and con necting parts. Fig. 2 is a side elevation looking in the direction of the arrow in Fig. 1. Fig. 3 an enlarged longitudinal section through the arbor of the mainspring-wheel, showing it also mounted in the clock-frame. Fig. 4 is a perspective view of the sleeve and its tightening-nut, said parts being separated. Fig. 5 is a perspective view of the arbor.
Figs. 6 and 7 are cross-sections of the sleeve,
showing modifications in the form.
A A indicate the two side plates 'of the clock-frame, which are of usual form.
B is the mainspring, and C the mainspringwheel provided with the usual ratchet and Serial No. 287,243- (No model.)
detent. The rest of the gearing is not shown, being of the usual construction.
Our improvement is as follows:
D is asleeve to which the mainspring-wheel is attached. The sleeve is made of just such 5 3 length as to fit removably between the side plates A A of the frame. Its interior a is of square form in cross-section. At one end the sleeve is out with two or more slits b b and provided with a screw-thread 0 cut on a bevel.
E is the arbor of the mainspring-wheel. It consists of a square body (1, two journal-bearings/"f, that rest and turn in the side plates of the frame, and a projecting square-sided stem g, that stands outside the frame and forms the winding-stem.
J is a nut that screws on the beveled end of the sleeve D, to clamp the same in place on the arbor, as will presently be described.
an is a hook on the end of the mainspring, which hooks over a pillar K of the frame. Any other suitable device for the purpose may be used, if preferred.
To attach the arbor in place, the sleeve D is first slipped up into position between the sidesA A of the frame. This is readily done, as the sleeve is of such length as to fit easily between the said sides. The arbor is then inserted endwise through the sleeve, the body d resting in the interior a of the sleeve, the journals ff resting in the sides of the frame and the stem g projecting outward beyond the frame. The nut J is then turned up on the beveled thread 0 on the sleeve, which clamps the end of the sleeve down firmly on the arbor and fastens said parts together. The clamping fastens the parts together, so as to turn as one device. The ends of the sleeve resting against the sides of the frame form stops to prevent end displacement. 0
The object in this invention is to avoid the cutting of screw-threads shown in our former patent, thus facilitating the insertion and removal of the arbor, lessening the expense and securing perfect protection against turning the arbor the wrong Way in cases of mistake in winding.
If desired, theinterior of the sleeve and the body of the arbor maybe made of other than square form in cross-section. Two such forms rco of; the sleeve are shown in FifgS. o and 7, one being trini'igulnr and the other elliptical.
If desired to furnish ndditionnl SQCUIfli/Q ngninst loose movement. npin 1) may be used, as shown in Figs. 1 and 3.
Having described our invention, what we claim as new, and desire to seeure by Letters llntent, is
1. In :t eloelc, the eombinntion, with the main wheel and spring, of. a sleeve titling between the sides ol the eloelelrsnne and n-ovided. with n smooth interior, a \vimflingarbor fitting loosely in said sleeve, the ends forming journals resting in the 'l'rmne and one end projecting, 'lforming' n winding-stem, and n :l'nstening deviee looking said mvrts tonether, ns shown and doseribed, and for the purpose sl'leeil'ied.
