T 0 all whom it may concern:

Be it known that I, GEORGE AL Hooves, a citizen of the United States, residing at Sallisaw, in the county of Sequoyah and State ofOklahoma, have invented a certain new and useful Improvement in Spring Mountings, of which thevfollowing is a spec fication.

My invention relates to improvements in spring mountings. v

It relates particularly to the type of spring mountings in which a coil springof the conolute type is mounted. in a drum to which the outer end of the spring is attached, the inner end of the spring being attached to an arbor rota-table relatively to the drum.-

The object of my vision of novel means for releasably attaching the inner end of the spring to the arbor in a manner such as to prevent the bending or breaking of'the spring in case'that the latter is wound and the'arbor or drum is suddenly released through accident or otherwise.

A further obj ect of my invention is the provision of novel means for reinforcing the drum so that a drum ofyrelatively light material may be employed with a relatively strong spring, without danger of bending or distorting the drum due to the tension of the spring thereon.

Still another object of my invention is the provision of a slip cover for the open end of the drum combined with means for holding the cover from circumferential movement on the drum and with the elimination of rivets,

screws and similar devices, such as are commonly used for fastening the cover on the drum.

My invention provides further a reinforcing member for the drum which increases the bearing surface of the drum on the arbor and also serves as a spacer between two drums mounted on thesame axial suport.

hly employment. of a plurality ed on the same axial support invention contemplates further the of drums mountcombined wlth novel means for connecting the drum units so that the power of their combined springs maybe employed for power urposes.

The. novel features of my invention are hereinafter fully described and claimed.

S1m1lar reference characters. designate 1 designates a support comprising a horizontal cylindrical bar mounted in the oppo--' site 'sides,2 of a suitable casing, a portion'of which isshown, inFig. 1. I

Nuts 3 mounted respectively on the screwthreaded ends of the bar 1 bear against the outer sides 2 of the casing'so as to retain the bar therein Rotatably mounted on the bar 1 are three

tubular arbors

4, 5, and 6, on which are respectively revolubly mounted three sleeves M -7, 8 and 9.

Three

cylinders

10, 11 and 12 are provided respectively with-closed

ends

13,14 and 15 which are respectively rotatably mounted on the arbors .4, 5 and 6, and in which are respectively mounted the sleeves 7,8a-nd9.

- The oppositeends of the

cylinders

10, 11 and 12 are normally respectively elosedby' slip caps 17 18 and 19, said capsbeing provided respectively with peripheral

annular flanges

20, 21 and 22, which respectively em- .brace the

cylinders

10, 11 and 12.

The cap 17 is rotatable on thebar1 and p and 19 are respectively rigidly secured to the right endsof the arbors 4 5, as viewed 111 Fig. 1, 1n the manner in Fig. 6. Upon referring to Fig. 6, it will be seen that the adjacent end of the arbor 4C is provided with two diametrically opposite end projections 23 fitted-in holes provided therefor in the cover- 18 so as to hold the arbor from turning in the cover.

The right end of the arbor 6, as viewed and shown in Fig. 1, has rigidly secured to it a rotary driving member, which may comprise a spur gear wheel'2l, from which power may be talten to drive a phonograph playing mech- 5 anlsm of a music boxor such other purpose as may be. desired. For reinforcing the

cylinders

10, 11 and 12, and for holdingthe covers 17, 18 and 19,

from circumferential movement o'nthe cylin- 1

ders

10, 11 and 12, respectively, I provide a 40 turningthe cylinder so as to wind the an -10, l1 and 12 and bet reinforcing member comprising a rightangled strap 25 attached to the periphery of the cylinder 10,.11 or 12, asthe case may be, by means of a rivet26, which is adapted to 15 be inserted through the outer end ofacoil spring 27-0f the convolute type, mounted in the cyllnder and embracing the sleeves 7, '8

. or 9, as the case may be.

Each-of the

flanges

20, 21 and 22 is pro.-

the adjacent reinforcing member 25 extends and is fitted to hold the cap from circumferentialnmvement. Each member 25 is provided with an outwardly extending projec' tion 29 provided at opposite edges with arms 30, Fig. 5, and F 4, which extend over the outer side of the flange of; the cover, s o t'liat-the'pull of the wound spr ng 27 will be exerted through the rivet 26 and the arms 1310i 30 upon the outer-sideof the flange of the cover, thereby reinforcing the drum.

i ,The other ends of the reinforcing members are respectively revolubly mounted on the-

arbors

4, 5 andti and are each provided with a raisedor cupped portion 31,

which serves as aspacer between the cylin- 66111116 spur gear 24 and thecylinder 12. 1

Any desired means may be provided for spring 27 mounted therein and th'ctwo other springs 27 mounted respectively in the cylinders l1 and 12.

20 a spur gear wheel 32 which meshes with I a. pinion'33 secured upon a horizontal shaft '34 extendingthrough and rotatablv mounted in the adjacent side 2 of the casing, and outi side of thecasing having secured to i'ta crank handle 35. e v

' Secured concentrically to thegear wheel 32 is a ratchet wheel 36-which is engaged by a. pawl 37 pivotally mounted on a horizontal inwardly extending stud 38 which is mounted in'the side wall 2 ofthe casing.

The inner ends of the springs 27 respectively embrace the sleeves 7. and 9. Said sleeves are each provided with a circumferential slot 39, as best shown in Fig. 2. Re-

6 spectively pivoted in the slots-59 are three pawls 10, each pawl being pivoted to the ad- 'iacent. sleeve by a longitudinal pm 41. Each of the springs 27 near its inner end is p'ro vided with a hole 42 adapted to receivethcrethrough an outwardly flaring projecvided in, its edge with a recess-28 into which Inthe drawing, I have shown attached to' theoutside of the cover {45 nism, not shown, which it drives, the crank handle 3.5 is turned so as to turn the cover 17 and the cylinder; lOcounter-clockwise, as vlewed'm Fig. 3, through the intermediacy of the

gears

32 and 33 and shaft 34.

The spring 27 in the cylinder 10 is'thtis wound and 111 'belngwound, carries with it the ad acent pawletO, which in turn rotates the sleeve -1- together with the cover 18 to, which 1t1s. attached'and the' cylinder 11in a:

direction such that the spring 27 in the cylinder 11 will be wound, thereby turning the sleeve 5, cover 19 and cylinder 12, through the intermediacy of the pawl-40 which engages the sleeve 5. The turning of the cylinder 12 will wind the spring 27 therein, which in turniwill be held at its inner end by the pawl 40 which engages the sleeve 6 attached .tothe gear wheel 24.

The crank handle 35 is turned in the-manner described until all the springs 27 are wound, the pawl 37 holding the cylinder 10 then be utilized for transmitting power to any desired mechanism from the wound springs 27. p

In case a spring should break, no damage ,will be done to the other two springs when they are thus suddenly released, as the pawls "40 will slip around with the 'uiilwlndmg springs out of engagement with the toothed sleeves with whichthev engage.

'By the employment of the reinforcing members 25, which assist the cylinders in 'supportingthe springs, the cylinders may be made of relatively thin material without danger of collapsing or distortion due to the strain placed upon them by the inward pull ot' the wound springs.
