9 Claims. (Cl. 74424.8)
' This invention relates to new and improved devices for automatically measuring lengths of material, such as thread and yarn.
Objects of the invention include the provision of a device having an element driven by the material to be measured as it travels, said element being connected to a settable device to travel the latter to a zero or knockoff point, whereupon the material travel is stopped at the point desired depending on the original setting; the provision of a device of the class described comprising a thread or yarn driven wheel, in turn driving means for moving a device from a predetermined set position to a knockoff point so as to stop the" thread or yarn travel; and the.
provision of a movable means for stopping thread or yarn travel, said means being set where desired for different lengths of thread or yarn and being automatically stopped at a zero orknockoff point so as to stop the travel of the material.
Further objects of the invention include the provision of a thread or yarn measuring device comprising a driven wheel in turn driving a threaded shaft, a movable wheel for selective engagement with the threads of the shaft so that as the shaft is turned, the movable wheel is moved longitudinally thereof from any set position along the length of the shaft, said shaft including a thread winder knockoff device for lifting the movable wheel from engagement therefrom and including a setting shaft for setting the wheel in av desired position according to the length of thread or yarn desired.
Other objects and advantages of the invention will appear hereinafter.
Reference is to be had to the accompanyi drawings, in which I Fig. 1 is a view in front elevation of a device embodying th invention,
Fig. 2 is a view in front elevation with the cover or top plate removed, x
Fig. 3 is a section on line 3-3 of Fig. 2 showing the wheel in engagement with the registering screw shaft, and
Fig. 4 is a view similar to Fig. 3 but showing the device in knockoff position.
.In the form of the invention shown in the drawings, the same comprises a casing or housing having a bottom I0, side walls l2, and a removable top or cover plate M, the housing being closed by end walls IS. The top or cover plate 14 is provided with a longitudinal slot as shown 'at l8 to accommodate an indicator element/20 which is located on a blade 22 fixed to .a nut 24 in mesh with a screw threaded setting shaft 26, the latter being journalled in the end walls It as shown in Fig. 2.
, Shaft 26 extends outwardly through one of the end walls [6 and is provided with a setting wheel 28 on which is mounted a spring-pressed plunger 30 rotatable therewith and engageable in a series of slots 32 in a fixed plate 34 on the housing of the device. It will be clear that by retracting the plunger 30, the hand wheel 28 may be rotated so as to rotate shaft 26 and the rotation of this shaft will set the blade 22 longitudinally thereof, the blade being held against rotation due to its proximity to one of the side walls l2, see Fig. 3. I
A screw threaded registering shaft 36 is journalled in the end walls It and is adapted to be driven as by a wormwheel 38 and a worm,
not shown, on a shaft 40, shaft 40 being in turn driven by a shaft 42 to one end of which is secured a measuring wheel 44, the latter havin a quarter or third yard periphery as desired. Setting screw 26 and registering screw 36 are provided with a definite predetermined difference in the number of threads per inch, and one practical relation is to provide the setting screw with ten threads per inch and theregistering screw with forty threads per inch so that the setting blade 22 may be travelled rapidly to vary the setting desired.
A rod 46 is journalled in end wall It and has fixed thereto a long bracket 48 having a pair of arms at the ends thereof mounting a small rod 50. Slidably mounted on rod 50 there is a wheel52 having a sharp periphery and designed for engagement with the threads of the registering shaft 36 so that as the latter is rotated, the wheel 52 will be travelled along. the registering screw 35. To hold the Wheel in engagement with the screw there is provided a snap spring 54 bearing on a short piece 56 secured to bracket 48, see Fig. 3, and as shown in Fig. 4, this spring will also hold wheel 52 and bracket 48' out of engagement with the registering screw 36.
,At one end of the registering screw 36 there is provided .a grooved enlargement or bump as at 58, this groove being a continuation of the screw threads thereof and causing the wheel 52 to rise at the end of the travel thereof so that the short piece 56 snaps under the angle of spring 54 to be held in the Fig. 4 position until manually returned to engagement with the screw.
Top plate l4 maybe calibrated into any units desired and it has been found that with the device as disclosed, any yardage can be measured from a few yards to over twenty thousand yards depending on' the settin of the blade 22 by the wheel 28. The slots 32 in cooperation with the plunger 30 holds the setting shaft 26 in any position desired and depending on the number of slots 32, the minimum amount of yardage may be varied. In the particular example of the in vention herein disclosed 2 /2 revolutions of wheel 28 will measure a thousand yards, 'but'this can, of course, be varied without departing from the scope of the invention.
The entire device is intended to be mounted at an angle to the horizontal so that wheel!!! will rest by gravity against blade 22 when the rod 46 is tilted up in the off position ofFig. 4, and as blade 22 is travelled downthe'screw Shaft 28, wheel 52 follows. Clearly, the farther wheel 52 must travel to reach the bump 58, the more yardage is measured.
