JAMES B. T. WILSON, OF CHESTER, SOUTH CAROLINA.

AUTOMATIC MEASURING AND STOPPING DEVICE.

To all whom it may concern:

Be it known that I, JAMES R. T. WILSON, a citizen of the United States, residing at Chester, in the county of Chester and State of South Carolina, have invented certain new and useful Improvements in Automatic Measuring and Stopping Devices, of which the following is a specification, reference being had to the accompanying drawings.

This invention is an improved measuring and stopping device for use on fly frames, roving machines, cotton spinning machines, etc., for automatically measuring the number of yards of roving or yarn wound on bobbins and stopping the machine when the predetermined number of yards have been wound.

The primary object of the invention is to provide a simple and effective device of mechanism of this character which will not be affected by taking up or slacking ends, or changing the tension gear, the construction being such that the use of the device will enable any number of frames of the same hank roving to be knocked oft with the same number of yards on all the bobbins.

Another object of the invention is to provide a device of this character in the form of an attachment which may be readily applied to the roller beam and driven from the front steel roll, but which may also be applied to other parts of the machines and driven from the main shaft, the top cone shaft, the spindle plate shaft, or the bobbin shaft.

WVith the above and other objects in view, the invention consists of the novel construction, combination and arrangement of parts, hereinafter fully described and claimed, and illustrated in the accompanying drawings in which Figure 1 is a view illustrating the applicat-ion of the invention to a slubber roving machine. Fig. 2 is a rear elevation of a portion of the machine showing the invention applied thereto, parts being broken away and in section. Fig. 3 is a vertical section taken on the plane indicated by the line 3-3 in Fig. 2. Fig. 4 is a top plan View. Fig. 5 is a detail section taken on the plane indicated by the line 55 in Fig. 1.

WVhile my improved measuring and knock-off motion 'or device may be used on fly frames, roving machines, cotton spinning machines and the like, I have illustrated in the accompanying drawings the Specification of Letters Patent.

Application filed May 9, 1910.

Serial No. 560,110.

preferred embodiment of the invention, and it is in the form of an attachment applied to a slubber roving frame.

In the drawings 1 denotes the main frame on which is mounted a roller beam 2; 3 denotes the front steel roll, and 4 denotes a horizontally disposed shifting bar or member which is adapted to shift a driving belt from a tight to a loose pulley (not illustrated) or to otherwise control the stopping and starting of the machine.

My invention comprises a spring-actuated means for shifting the bar 4:, a catch for holding the shifting means inoperative, and a releasing means for the catch actuated from the front roll 3 or other part of the machine. When the roll 3 is employed for this purpose it is provided with a worm 5 which meshes with a worm gear 6 fixed to one end of a shaft 7 the latter being here shown as mounted in bearings on a bracket 8 fixed to the roller beam 2. Fixed to the shaft 7 is a beveled gear or pinion 9 which meshes with a beveled gear 10 on a shaft 11 journaled in bearings 12 on a supporting member 13. The latter is here shown in the form of a plate vertically disposed and depending from the rear side of the beam 2, to which latter it is secured by bolts or fastenings 14. Arranged on the shaft 11 is a worm 15 which meshes with a worm gear 16 mounted on a stub shaft 17 adjustably secured to the plate or member 13. The worm gear 16 is adapted to serve as the measuring wheel and it is removably mounted on the adjustably mounted shaft 17 so that it may be replaced by a similar gear of different size for the purpose of determining the number of yards of roving or yarn to be wound on the bobbins at one operation of the machine. The shaft 17 has its inner end adj ustably clamped by a nut 17 a or other means in a slot 13 in the plate 13, see Fig. 1. By constructing the device in this manner so that the gear 16 may be quickly changed, the machine may be set to automatically wvind any predetermined number of yards of yarn on the bobbins. Fixed to the gear 16 is a pin 18 adapted to engage and actuate a cam 19 loosely arranged on the shaft 17 and adapted to in turn engage and actuate a latch lever 20. This lever controls a knockoff or shifting lever 21 which is vertically disposed so that its upper free end engages an adjustably mounted stop 22 provided on the shifting bar or member 4:. The intermediate portion of the lever 21 is fulcrumed on a stub shaft 28 which is horizontally adjustable in the supporting plate or member 18 by clamping it in a horizontal slot 24 formed in said plate, see Fig. 4. The lever 21 is actuated in one direction by a coil spring 25 arranged on a guide rod 26 which has one of its ends pivoted to the lower extremity of the lever 21, and the other end of saidvrod slides through an opening 27 in a support 28 which may be one of the standards of the main frame. The latch lever is horizontally disposed and has one of its ends pivoted at 29 to the lever 21 adjacent the fulcrum 23, and the other end of said lever 20 is slidably arranged in a slot 30 in of the latch lever.

In operation it will be seen that the motion of the front steel roll 8 will be imparted to the shafts 7, 11, and hence to the measure gear or wheel 16, and when the latter makes a complete rotation, the pin 18 on it will slowly elevate the cam 19 until the latter lifts the latch lever 20 and disengages its shoulder 31 from the support 28. When this happens, the spring 25 actuates the knock-off lever 21 and the upper end of the latter being engaged with the stop 22 shifts the bar 4 which throws the driving belt of the machine from the tight to the loose pulley, thereby stopping the machine. After the machine has been doffed the parts may be reset by lifting the latch lever 20, returning the cam 19 to normal position, and then shifting the lever 21 to place the spring 25 under tension and to engage the shoulder 31 with the support 28, as shown in Fig. 2.

From the foregoing it will be seen that my improved knock-off motion and measuring device is actuated from the front steel roll and is entirely free from connection with the cone rack so that its chief advantage over other similar devices is that it will knock the machine off with the same number of yards on all of the bobbins except where ends or strands of cotton are left down, or roving stretched on account of heavy stock.

I have found in practice that the use of the invention will elfect the saving of from 10% to 20% in labor necessary to operate the ordinary fly frames and roving machines; that it will increase the production of the machines using the roving taken from machines equipped with my device from 4 to 5%, since there will be fewer ends down on account of singlings made, making it pos sible for the operative to keep his frame, or machine, running more regularly; that it can be creeled faster and easier; that it will improve the quality of the work from 10 to 20%, as there will be fewer ends to be pieced in back of creel, thus eliminating many thick and thin places in stock as it is impossible to piece ends of roving together without making thick or thin places, and of course the fewer piecings made, the better the quality of stock produced; that it will reduce the waste from creeling 50%, and there will be 50% fewer pieces to be run up a second time; that it will produce uniform roving so that the roving of the same hank from any number of machines may be placed in a single machine and have it run out even, the same as if all of the rovings had been taken from one frame.

In the practice of my invention I prefer to provide with the attachment, the shift rod 4 which takes the place of the usual shift rod on the machine.

lVhile I have shown and described in detail the preferred embodiment of my invention, I wish it understood that I do not limit myself to the construction, and arrangement of parts set forth, since changes and variations may be made within the spirit and scope of the invention.
