i ANTISPINNING DEVICE FOR GLOTI-I-IvIEASURING MACHINES.

Application filed November 25, 1922. Serial No. 603,882.

T 0 all whom it may concern:

Be it known that I, ANTHONY VANDER- van), a citizen of the United States of America, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Improve ments in Antispinning Devices for Cloth- Measuring Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an automatically operating means in conjunction with the imeasuring roller of a cloth measuring machine for stopping rotative movement of the roller immediately when the cloth has passed by the roller, as in the measuring of end pieces or remnants of cloth or the like in the machine. Without this means, it is possible to cause the roller to turn a. considerable amount after the cloth has passed, thereby giving a larger amount on the indicating means operated by the measuring roller than 1 is the actual length of the cloth measured.

The present invention is designed to stop the roller against such rotative movement through the agency of a brake applied to the roller automatically with the departure of the end of the cloth from the roller, and it is a primary object and purpose of the present invention to provide this means in simple form and of such construc tion that its working is sure and positive at all times for the accomplishment of the ends desired, no possible over measurement of the goods occurring. Many other minor objects and purposes subsidiary to this main purpose will later appear as understanding of the invention is had from the following description of the invention illustrated as to its preferred embodiment in the accompanying drawings, in which,

Fig. 1 is a fragmentary'vertical section through the measuring roller and adjacent parts of a measuring machine equipped with the invention.

Fig. 2 is a fragmentary vertical section through the machine at a plane back of the plane of the section shown in Fig. 1.

Figs. 3 and 4 transverse vertical sections through the measuring roller and the control means therefor, showingsaid means in two different positions, in one of which the said means is inoperative and ineffective, andin the other operative and effective, the

used to be controlled by the cloth passing through the machine for governing the position of the brake with respect to the measuring roller.

Like reference characters refer to like parts in the several figures of the drawings. 1

As constructed, the machine includes a base 1 from which an integrally cast post 2 extends upwardly, the mechanisms of the measuring machine being located above said base and covered by housings 3 and 4, the latter of which is located at the lower front portion of the machine and including a horizontal table separated from the adjacent lower edges of the upper housing 3 a short distance, thereby providing a slot 5 through which the cloth 6 is drawn in operating the measuring mechanism of the machine.

The measuring mechanism includes a measuring roller 7 secured on a shaft 8, the front end of the shaft being rotatably mounted in a roller bearing 9 located in a suitable housing 10 which is permanently secured to the rear side of a front'plate which, together with other plates 11 at the sides, and a rear plate (not shown), constitutes asupporting frame for carrying the mechanism. The housing for the roller bearing has a cylindrical outer surface except at two diametrically opposite points where it is flattened, as indicated at 10 The cloth 6 is pressed against the roller lowering of the presser roller 12,- moving it away from the measuring. roller and holding it away until the handle 19 is operated in the opposite direction. The construction so far described is old and has been previously 7 invented and built by me.

rll.

An irregularly shaped member 20, of the shape shown in Figs. 5 and 6 is positioned transversely of the machine in front of the front end of the measuring roller and back of the plate 11 on which it is pivotally mounted between its ends at 21. One end of the member has a rearwardly extending arm 22 (Fig. 8) which extends parallel to the axes of the rollers 7 and 12 to one side of their line of contact engagement. The opposite end of the member is extended beyond the pivot 21 for a distance as shown at to lie under a. lever 2d pivotally mounted between its ends at 25 to a side plate 11 The opposite end of lever 24 (Figs. 2 and 5) eX- tends to cam 17 which is provided with a second cam projection 17 shaped so that on rotation of the shaft 18 said end of the lever is elevated through movement of the cam, the opposite end of the lever depressed, and member 20 turned on. its pivot 21, thereby elevating the end of the member at which the arm 22 is located. The roller 12 is simultaneously lowered, as before described and the slot at 5 is left clear for the placing of the cloth 6 between the rollers, as at the beginning of a measuring operation.

A roller carrying cage is loosely mounted on and around the housing 10. The cage comprises two ring shaped ends 26 and 27 (Fig. 7) connected by pairs of bars 28 at opposite sides of the rings, the bars of each pair being spaced apart to provide a longitudinal recess 29 between them. The outer end ring 27 hastwo spaced apart pins 30 projecting therefrom, and at the inner end ring a sheet metal circular member 31 is se cured by screws (Fig. 1) to complete the cage and close the ends of the recesses 29, re taining the rollers 32 located in such recesses from endwise movement. The cage is stopped from endwise movement on the housing by the heady of screw 31 which passes through the housing to hold the roller bearing in place, the ends of pins 30 coming closely adjacentthe supporting plate 11 to insure against outward endwise movement of the cage. It will be noted that in the normal position of the cage with the rollers 32 therein, the rollers tend to run down the incline on the upper sides of the lower bars 28 until stopped by engaging against the flattened sides 10 of the housing 10 as shown in Fig. 3.

A second irregularly shaped member of flat metal, shown at 33 (Fig. is pivotally mounted between its ends-at- 34 on the plate 11, the downwardly extending end thereof below the pivot being forked, as at 35, to connect with a pin 36 projecting from the member 20. The member 33 extends horizontally and slightly upward in the other direction away from the pivot, is then turned in a downward direction substantially to the plane of the pins 30 and terminates in aninturned end 37which passes between the two pins. A spring 38 of slight strength is connected to the heavier end of the member 33 serving to substantially balance the same. (See Figs. 5 and 6).

lVith this construction, with the cloth 6 located under and elevating the bar 22, the irregularly shaped member 20 is turned about its pivot thereby giving a limited movement to the second irregularly shaped member 33, ser ing to hold the roller cage and rollers 32 therein in the position shown in Fig. 3, the measuring roller being freely rotatable. As soon as the end of the cloth passes by the measuring and presser rollers, the bar 22 drops to the position shown in Fig. 6, with an actuation of the member 33 and a turning of the roller cage and rollers to the position shown in Fig. t, the rollers 32 being moved outwardly to engage against the inner sides of the measuring roller 7, such movement being caused by the travel of the rollers 32 on the flattened sides 10 of the housing 10. A wedging action is provided serving a sure brake against further movement of the measuring roller until the member 20 is turned in an opposite direction. This is done by operating the operating handle 19 in a downward direction tov separate the presser roller from the measuring roller this, as earlier described, operating lever 2st and through it the member 20 so as to raise the bar 22 to an upper position, holding it there to permit the introduction of a. succeeding length of cloth for measurement and freeing the measuring roller from the brake action to permit freedom of movement thereof. This freedom of movement continues as long as cloth is under the-bar 22 or until the end of a remnant is reached, the brake action coming into play immediately after the end of the cloth has passed from the measuring and presser rollers.

It is to be understood that there is shown only a portion of the machine or so much as is necessary to illustrate the invention. The complete machine is shown in my Patent No. 1,e20,612, issued June 20, 1922. In machines of this character the cloth 6 is placed between the rollers 7 and- 12 when the sameare separated by operating thelever 19', the member 20 being moved t6 elevate the" part 22 thereof. WVhen the lever 19 is moved back to original position,- the member 20 is re leased and the part 22 thereof drops on to the upper side of the cloth, the roller'l2 at the same time being elevated to press the cloth tors further so as to indicate a greater nieasnrement of cloth than has actually taken place. Q y I Ovenn fiin (if the machine is; positively prevented and an insurance made against charging the customer-for more than is delivered.
