SPECIFICATION forming part of Letters Patent No. 505,436, dated September 26, 1893.

Application filed May 8, 1893.

To all whom it may concern.-

Be it known that LWILLIAM PITT GANNING, a citizen of the United States, residing atLowell, in the county of Middlesex and Commonwealth of Massachusetts, have invented certain new and useful Improvements in Fly- Frames, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to spinning machines of the class known as fly-frames, and, in particular, it relates to the devices which are employed in fly-frames for the purpose of moving the cone-rack to shift the cone-belt along the cone-pulleys, and to the connections between such devices and the stop-motion devices which are employed in such frames.

United States Letters Patent No. 484,776, granted to me October 25, 1892, shows and describes, and also claims, a certain form and arrangement of the parts whereby motion is transmitted automatically from the tumblingshaft of a fly-frame to the cone-rack, and presents, also, connections with the automatic stop-motion devices of the fiy-frame, of such character that, whenever the shipping devices of the fly-frame are operated automatically to effect the transfer of the driving-belt from the fast pulley on the driving-shaft to the loose pulley on the said shaft, a break or disconnection shall be occasioned in the train of transmitting gearing. This break or disconnection leaves the cone-rack free to be moved by hand into any desired position in the flyframe during the stoppage of the fly-frame, such movement by hand being eifected, for instance, in winding up the frame by hand after the completion of the Winding-on upon one set of bobbins and preparatory to restarting the fly-frame with a fresh set of bobbins.

The present invention is in the nature of invention which is mentioned above as being presented and covered by the patent just mentioned, and its main objects are to secure a simplified construction and arrangement of parts, and to enable the break or disconnection in the gearing, and the re-engagement, to be occasioned Without danger of unintentionally gaining or losing a tooth in consequence of slight move- Serial No. 473,402. (No model.)

ments of the gears occurring during the time of the break or disconnection.

My present invention consists in a certain novel construction and combination of parts which I shall now proceed to describe with reference to the accompanying drawings, in which latter are represented the best embodiments thereof that have yet been devised by me.

The characteristic features of the invention are particularly pointed out and clearly defined in the claims at the close of this specification.

In the drawings, Figure 1 is a view in rear elevation of part of a fiy-frame with my invention applied thereto, suflicient of the flyframe being shown to render evident the re lations and connections of my improved devices. Fig.2 is a view thereof in vertical sec-' tion on the dotted line 2-2 of Fig. 1, looking from the right in the latter figure. Fig. 3 is a view in detail in vertical section on the dotted line 3-3of Fig. 1. Fig. 4 is a detail View showingin elevation, as viewed from the left, in Fig. 1 certain of the parts which are represented in the latter. Fig. 5 is a view in rear elevation showing a modification. 'Fig. 6 is a view in vertical section on line 6-6 of Fig. 5, looking toward the right in the latter figure.

In the drawings, 1 is the machine-frame. 2 is the tumbling-shaft. 3 is a horizontal shaft which is geared to the lower end of the tumbling- shaftbygears'L 21 and 31, 32 is a bevel-pinion mountedon said shaft, 3, and in mesh with a betel-gear, 4, on a short upright shaft, 41, which" carries at its upper end aspur-pinion, 42, that serves to transmit motion through a trainof spurgears and pinions, 43, 431, 432, to the upright shaft, 5, the latter having mounted on its upper end a spur-pinion, 51, in mesh with the teeth of the cone-rack, 6. The gear, 43, and

pinion, 431, are connected, as by a pin, 433, 1

and turn together upon a stud, 434, the lower end of which passes through a slot at 435 which is provided in a supportingpiece, 436, the stud being clamped in place in said slot by means of a nut, 437, and washer, 438, on W its threaded end below the supporting piece,

too

436. The pinion, 431, may be replaced. by others of varying sizes, and, after change thereof, the stud, 434, may be shifted in slot 435 in known manner to place the teeth of the pinion, 431, in proper mesh with those of the gear, 432, which last is mounted on the shaft, 5. By the described devices intermittent motion is transmitted automatically to At8- is the usual stop-motion lever, it having a notchedarm, 81, extending outsubstantially horizontally and loaded with a weight, 8152, and also having a. depending. arm, 82, to which; is pivotally connected one end of; a hooked or notched latch, 8.2.1, the hooked. or free end whereof projects through a hole-,,l1, in a, portion of the fram-ing,.and remains engaged with theedge of. the said hole in. the manner; shown in Fig. 1 during the regular working. of the fly-frame.

In my Patent. No. 484,77 6, I- h-ave-showxrthe stop-motion lever, 8, combined with a cert-ainarrangement of parts whereby, whenthe hooked on notched latch is disengaged from itsholdon the stationary framing, and the said lever is allowed to: turn under theinlfi uenceofi the; weight that is applied thereto in manner as described herein, a. break is, occasioned in; the train. of gears. by which the uprightshaf t correspondingzwiththat marked 5 herein is-opera-ted from the horizontal shaft herein marked 3. In the said patent, the break is effected by raising a movable arm or gear-carrier supporting a series of spurgears and pinions. Herein, I combine the said stop-motion lever with an arrangement of parts which itis intended shall secure the same general. result, but herein the parts are much simplifiiedand aredifferentlyarranged and; operated. I employherein a rod, 9, resembling the rod shown in. thev said patent, such rod-bei-ng'pivotall-y connected herein at its upper: end with the arm, 81, of the stopmotion lever,,8, and, in the patent, serves for connecting the stop-motion lever, 8, with the arrangement whereby the engagement of the gearing is broken and reestablished. I now: cause the said rod, 9, to actuate a rocker having; connected therewith a fork entering a. groove in thehub of the bevel-pinion, 32, and, L spline the said bevel-pinion on the-said shaft, 3, or'otherwise connect the bevel-pinion, 32,,with the shaft, 3, in equivalent manguide, 122, carried by the a spiral spring,

ner, so that the bevel-pinion may move endwise of the shaft while still turning therewith.

Figs. 1, 2, and 4, show an embodiment of my invention in which the rocker is constituted by a simple bell-crank lever, 10, pivoted at 101, the arm, 102, of the said lever being connected with the rod, 9, and the arm, 103, thereof, being connected with the fork. The fork is shown at 11, (see also Fig. 3,) its arms entering the groove, 321, in the hub of the bevel-pinion, 32. The eye of the fork is slipped upon a rod, 12, and secured in desired position thereon by a clamping-screw, 121, one end of the said rod passing through a framing, while the other end thereof passes through a hole in a vertical part of the framing, see Fig. 4, and isxprovided with an arm, 123,,which plays in a slot, 1031, formed in the arn1,.103, of the bell-crank love-1510,. as shown clearly-in Figs. 1 and 4.

Figs. 5: and 6- show arocker consisting of a. horizontal rock-shaft, 13,, provided with a' horizontally extending arm, 131., with which the rod, 9, connects, and with a depending arm, 132, having directlyconnected therewith the fork, 133, which engages with the bevelpinion-,,32, the connection between the arm 132. and fork133 being-efiiectedflby casting the two in onepieceh Inboth constructions, the rod, 9, passesthrough a; hole in the arm of the rocker with which; it connects, a collar,,91, being placed. on; the rod above the arm and fixed in place by'a clam-pingscrew, 911, and 92, being placed on the rod below thearin and compressed between the latter anda: collar, 93,,which is fixed in place on the end of. the rod by a clampin-g-screw, 931. The object of this spring is. to prevent injnryand breakagefro m resulting-when the teeth of the: sliding be-velrpiniom. 32, do not reenter properly into mesh with the teeth of the bevel gear, 4,.after being disengaged. Should the teeth fail to enter properlyinto mesh at first, the; spring will, yieldas the stopmotion 1ever,.8,, is moved into the position which it occupies: during the running of the fly-frame, and: when therotation of the bevelpinion,,32, withthe shaft, 3, has moved. it a sufficient. angular distance to place its teeth in proper position relative tothoseof the bevelrgear, 4,v for res-engagement, the spring will operate to throw the bevel-pinion into proper engagement with thebevel gear. When the stop-motion. lever isshifted in posit-ion in order to'occasiontthe stopping of the fly-frame, the connections herein presented slide-the bevel-pinion, 32, away from the bevelgear, 4, leaving the cone-rack, 6, free to be adjusted in the direction of its length into any desired position by means of shaft, 7,.and its hand-wheel, 71,, and spur-pinion, 72.

In consequence of occasioningthe break in the gearing by sliding the bevel-pinion, 32, longitudinally of the shaft, 3, on which it is splined, there is no danger of the gearing be coming deranged in position in a manner which will interfere with the bevel-wheels becoming re-engaged precisely as they were before, unless the parts are intentionally moved during the time of the disengagement.

In some fly-frames, the rocker may be operatively connected with. some member of the stop-motion devices other than the stop-motion lever herein shown.
