Oct. 25, 1938. J. E. MARTIN MEASURING AND MARKING DEVICE Filed July 15, 1937 mwmmwwmm Patented Oct. 25, 1938 UNITED STATES 1 Strutwear Knitting Company, Minn., a. "corporation of Minnesota Minneapolis,

Application July 15, 1937. Serial Nb. 153,744 2 Claims. (01. 33-'1s9) This invention relates to measuringand marking devices, and more particularly-to devices for measuring tape-like strips of fabric and'marking said strips to indicate the measureineritsob tamed. Q 7 .J 1 2 One of the objects of my invention is-t'o pro vide a simply constructed device of relatively lit-' tle cost which can be set up in a confined space and easily adjustedto provide for varied meas urements. 7

Another object of the invention is to provide a measuring and marking device which is "abso lutely fool proof in operation with the result that even an inexperienced person who has never seen the device before can use it without any instructions from an experienced person.

Another object is to provide means for properly supporting and guiding the tape through the measuring mechanism.

Still a further object is to provide simple and efficient means for removably supporting the rotary measuring element utilized in the device.

These and other objects and advantages of the invention will be more fully set forth from the following description made in connection with the accompanying drawing, wherein like reference characters refer to the same or similar parts throughout the various views, and in which:-

Fig. l is a side elevation of the device with certain parts broken away toshow details of construction;

Fig. 2 is a section taken approximately on the line 22 of Fig. 1, and 1 Fig. 3 is a fragmentary detail of the markin device associated with the measuring roll.

} In the embodiment of my invention shown in the drawing, I have shown a base element 4 which has a central bore adapted to receive a vertical support rod 5. This rod may be securely held Within the base by means of a set-screw 6.

Secured on the rod 5 for vertical adjustment thereon is a collar 1 held by a set-screw 8. This collar is rigidly secured to a U-shaped frame member 9, the vertical arms of which are provided with longitudinal slots I0 extending from points near the lower portions of said arms to the tops thereof. Mounted in the lower portion of the U-shaped frame 9 is a receptacle H which is adapted to hold a supply of a liquid marking substance. A wick 12 extends upwardly through the top of the container II and said container, is provided with laterally extending channelshaped elements l3 which are adapted to engage the sides of the U-shaped frame. Just above the container H and extending inwardly from the arms of the U-shaped frame 9 are bolts l'4 threadedly secured within the arms of said frame andrigidly positioned by nuts l5; The inner portions of the bolts are adapted to rotatably carry bearing elements 16 and, as best shown in Fig. 2, these bearings and their supportingbolts M are spaced from each other an appreciable distance. A measuring roller H is provided with short, laterally extending axle-like elements l 8 and said roller which includes a relatively thin web I9. 0 and wide flange 20 is provided with notches 2| cut into said flange at one point so that when the axle-like elements l8are placed in the slots'lfl' in the 'U-shaped frame 9, the roller can be dropped downwardly to the position shown in 15 thedrawin'g, the notches '2l permitting the outer flange 20 to pass the bearing elements I6. Thereupon the inner flange 22 which is concentric with the outer flange and positioned inwardly toward the hub of the roller, acts as the bearing contacting surface. This is clearly shown in Fig. 2.

The outer flange 20 of the roller I1 is also provided with a transverse groove 23 adapted to receive a brush-like marking strip 24, and the roller supporting bearings are so positioned relative to 25 the wick I2 in the container II which holds the liquid marking material, that rotation of the measuring roll causes the marking brush 24 to pick up marking liquid from said wick, as indicated in Fig. 3. 3o

Extending from one side of the U-shaped frame 9 is a right-angle bracket 25 whose vertical portion is adapted to carry a second angular bracket 26. This latter bracket is slotted at 21 anda spring tension nut and bolt assembly 28 extends through the two brackets to permit vertical sliding adjustment of one bracket relative to the other. A horizontal bar element 29 is adjustably secured to the vertical support rod 5 by means of a set-screw and collar shown generally at 30 and the outer end of the rod 29 is bent at right-angles to carry a reel 3| upon which is found a length of tape 32. The reel supporting rod 29 is in alignment with the measuring roller I1, and I have provided a flat tubular guide element 33 secured 45 to the vertically adjustable angular bracket 26, by means of a spring nut and bolt assembly 34. The tape is fed through the guide element 33 to the measuring roller l1 and an idler roller 35 is placed in above the measuring roller I1 and held between the arms of the frame 9 by means of projecting axle pins 36 similar to the pins l8 on the measuring roller. I

Thus it will be seen that when the tape has been first fed into position, it is necessary only marking fluid from the wick l2 in the container a point corresponding to the circumferential" measurement of the measurlng'roller. If a different length of tape portions is desired, it is necessary only to slip out the idlerroller and' the measuring roller and'insert anothermeas-" uring roller of different diameter thanthe one removed. Thus a set of varioussized rollersican be made available for one device and when different measurements are desired, the substitu tion of measuring rollers can be easilymade. The vertically adjustable bracket element 26 which holds the guide .33 can be moved up or down when differentroller sizes are inserted. The size of the idler roller is immaterial, but it should be fairly heavy. L V

From-the foregoing it will be seen that I have provided an extremely simple and highly eflicient device for measuring and marking fabrics taken from rolls. Of course, if wider fabrics are to be measured, it is conceived that the entire device can be made to accommodate these extra. widths. The device is relatively compact and may be placed upon a sewing table in a factory so that a worker can quickly and conveniently secure a length of tape of exactly the desired measurement without having to do anything more than pull thefree end of the tape until the desired length has been indicated by the colored marking placed thereon by the brush on the measuring roller.

It will, of course, be understood that various changes may be made in the form, details, arrangement and proportions of the various parts without departing from the scope of my invention.

What is claimed is:-

1. A measuring and marking device for strip fabrics and the like, comprising a measuring roller, a marking device upon and movable with said measuring roller, means for supplying a marking material to said marking device, an idler roller mounted above and resting upon said measpuringroller, and means for guiding said strip fabric between said measuring and idler rollers.

2. In a measuring and marking device for strip fabrics and the like, a measuring roller having aplane, circular web and a relatively broad circumferential flange carried by said web, a sup:

port for, said measuring roller comprising slotted spaced elements adapted to receive the axle of said rollers, and oppositely disposed aligned bearing elements carried by said support and spaced from each other a distance slightly greater than the thickness of said web, said circumferential flange having notches extending inwardly to said web at one point on said roller, and a circular bearing contacting flange extending from said web at either side thereof and positioned radially inwardly from said circumferential flange.

JOHN, MARTIN.
