To all whom, it may concern:

Be it known that I, JosEPH BORNAND, a

citizen of the Republic of Switzerland, residit consists in certain details ofconstruction of such motors, as fully set forth hereinafter and as illustrated in the accompanying drawin s, in whichlgure 1 is a sectional elevation of a spring motor embodying my improvements. Fig. 2 is an inverted plan view, the casing removed. Fi 3 is an inverted view. in partial section on t e line 3 3, Fig. 2. Fig. 4 is a side view of the brake device. Figs. 5, 6, and 7 are lan views of partsof the brake'device detac ed. Fig. 8 is'a perspective view showing the end of the shaft that supports the spring-barrel. Fig. 9 is an end view of the winding-shaft.

The frame A of the machine consists of a top platform 1 with pendent brackets beneat supporting the operating parts, the said latform fitting the top of a casing B, whic incloses the parts beneath the platform. The said brackets have bearings for the winding-shaft 2, which extends through the side of the casing and is provided with a pin ada ted to a notch of a separable handle 3, by w ich the shaft may be turned, turning therewith a pinion 4, which meshes with a gear 7 upon a second shaft 8, upon which is supported a drum or barrel 13, containing a spring 12, secured at one end to the barrel and at the other to the shaft 8. Preferably the inner end of the spring is secured to the shaft 8 through the medium of a sleeve 10',

,- fitting the contracted end of the shaft 8 and operating upon flattened faces 11. 11 thereof and held in place by a detachable collar 50. This facilitates the construction and the removal of the parts from the shaft 8, as by" detaching the collar 50 the barrel and the sleeve 10 can be Withdrawn from the shaft 8 and as readily re laced and again secured, by means of the collhr.

The ower of the spring is transmitted to a vertica ly-driven shaft 21 through suitable gearing. As shown, the said gearm consists ai'rel 13 and meshing with a pinion 15, carried by a sleeve 51, turning upon a stud 16 andprovided with a bevel-gear 17, that engages a Specification of Letters Patent.

Application filed November 29, 1905. Serial No. 289,626.

Patented Nov. 27, 1906.

I bevel-pinion 18 upon a vertical stud 52.

The bevel-gear'18 is connected with a spurgear 19, which engages a pinion 20 on the riven shaft 21.

. The rotation of the shaft 2 by means of the handle 3 is the means of turnin the shaft 8 and winding up the spring, an to revent the reverse action of the shaft 8 the" atter is providedwith a ratchet-Wheel 9, which engages the L-shaped pawl 5, hung to the shaft 2, and is pressed against a bearing on the latter-as, for instance, the pinion 4.-by a a spring 6.

The friction between the pawl and the bearing on the shaft 2 insures that the'pawl shall be carried from the ratchet when the shaft is turned in the direction of its arrow, Fig. 1, to wind up the spring, and this winding therefore is effected Without the noise which usually results from the slipping of a pawl on the ratchet-teeth. When the spring reacts and tends to turn the shaft 2 in theopposite direction, the friction against the pawl insures that it shall be swung In a position to engage the teeth of the ratchet.

The a aratus is rovided with a overnor G of suitable character. upon the shaft 21 engages a worm 23 u on a shaft 54, turning in suitable bearings an carryin a sliding sleeve 26, which is forced outwar by a spring 55, and to which are connected two spring-blades 24c 24, each bolted to a block upon the shaft 54 and each connected at the outer end to the sleeve 26. At the outer end of the sleeve 26 is a disk 27, and upon each spring-blade 24 is supported a weight 25, so that as the rotation of the shaft causes the weight to fly outward the disk 27 is brought frictionally against any suitable frictional bearing to thereby create a resist- As shown,a gear 22 ance to the too rapid movement of the parts driven from the spring. While any suitable coacting bearing may be employed in connection with the disk 27, I prefer to make use of a fork 56, carrying two blocks 28 28 at its ends, each with a pad 29 in position to receive the thrust of the disk 27, and this fork may be shifted so as to act as a friction-stop.

As shown, the fork is carried by a rock-shaft 30, around which is coiled a spring 33, that tends to carry the fork toward the disk. From this rock-shaft extends an arm 32 below the lower cam end of a vertical shaft 31, turning in the platform 1 and provided with a knob 59, upon turnin which the shaft 30 isrocked to carry the for away from the disk stud 61, projecting upward but, as shown, it is adapted to a socket in the hub of a disk; 34, adapted to receive the disks of a graphophone. 1

In order to act upon the disk 34 to start and stop the machine, I make use of abrake D, having a shoe 35, adapted to act u on the periphery (of the disk. As shown, t e shoe v 35 18 upon an arm 60, swingi-n freely upon a cm the platform 1, and below the arm 60 is a plate 64, having two separated shoulders 42, and above the arm 60 is an arm 3'7, having two shoulders 38 separated, but to a less extent than the shoulders 42. Upon the arm 60 are two studs 39 i1, projectin respectively, upward and downward with an intermediate cam-surface 53, and a-spring 36 is coiled edge of the disk 34.

When in its inner position,the arm 60 can swing independently of the arm 37 under the pressure of the spring to the extent to which thestud 39 can play between the shoulders 38, but when the arm 3711s swung outward the outer shoulder 38 contacts with the stud 39 and swin s the arm 60 to carry the shoe 85 away from. the edge of the. disk, and the arm 60 is held in this position by the friction of the Washer 68.

Without limiting myself to the constructions shown, I claim- 1. The combination in a spring-motor of the barrel-shaft having shoulders, a sleeve.

detachable longitudinally from said shaft and with shoulders at the inner end engaging those of the shaft, a drum rotatable on the shaft, and a coiled spring connected with the drumend with the sleeve.

2. The combination with the barrel and spring of a motor, of a shaft extending through said barrel and. provided With a reduced end and with fiat faces 11, 11', onthe lar er part adjacent to said reduced portion, a s eeve on said shaft and bearin on said faces,means for connecting the spring to the barrel and to the sleeve, and means for holdin the sleeve longitudinally on the shaft,

su stantially as set forth.

3. The combination with 'the winding shaft and barrel-shaft of a spring-motor, of.

intermeshin gears, a' awl swinging on the windingsha t, means or holding it frictionally against the ear thereof, and a ratchet on the barrel-shait engaged by the pawl, su' stantially as set forth.

In testimony whereof I afix my signature in presence of two witnesses.
