not cut through the rubber, consequently is pushed back a distance equal to the thickness of the sheet of rubber which is being measured. The amount of this backward movement of the flat gage roll is in the manner described indicated in thousandths of an inch by the dial pointer; thus practically instantly without stopping the calendering machine or interfering with the running out of the rubber sheet the thickness of the sheet can be gaged to ascertain whether or not it is coming too thick or too thin. The disks, of course, eut through the rubber, but as the rubber is soft and sticky and particularly if it is to be immediately applied to a fabric, when it is passed between the rolls which unite it to the fabric the slits which the disks cut are closed together. In measuring the thickness of the sheet as it comes from the calender rolls, or in ascertaining whether the sheet is varying from the desired thickness, the instrument can be held by the hands and thrust radially toward the axis of the calender roll on which the sheet is running, or it may be rested upon a bar or bracket and thus thrust against the calender roll.

In the second form of instrument illustrated, instead of having two cutting disks and one gaging roll, as in the above described form, there is one cutting disk, which is immovable with relation to the handle, and two fiat rolls, which are held by a slide movable on the handle and are moved backward according to the thickness of the sheet being measured. In this form the cutting disk 15 is mounted in the forked end of a frame 16 which is desirably tubular. On this frame is an ear 17 bearing a stop screw 18 with a lock nut 19. The dial gage 2O is fastened to this frame. Moving on the outside of this frame is a tubular slide 2l carrying a pin 22 which projects upwardly through a slot in the frame between the stop screw and the stem of the dial gage. On the forked front end of this slide are the gage rolls with flat surfaces 23. A spring 24 with one end fastened to a pin 25 in the frame and the other end fastened to a pin 26 in the slide draws the slide forward and holds the pin against the end of the stop screw. When this structure is used the cutting disk penetrates the material and the broad Hat surfaces of the gage rolls force the slide back and through the pin carried by the slide cause the dial to indicate the amount of backward movement of the rolls, and consequently the thickness of the sheet being measured.

In the form shown in Fig. 7 the rolls are arranged in a vertical plane. In this form one roll 27 is mounted on the forked end of the slide 28, which has a pin 29, and the other rolls 30 are mounted on forks at the ends of the frame 31. This frame is provided with astop screw 32 which bears against the opposite side of the pin carried by the slide, from the point where the stem 33 of the indicating dial bears.

Instruments embodying this invention, besides being used for gaging a sheet of rubber on a calender roll, may be employed during the gaging of a calender roll which is in the process of being ground, so that a true sheet will be produced. When these rolls are being formed it is customary to grind them with a slight crown which will when rolling the particular stock in question just counteract the spring of the rolls under the work of rolling a sheet, and thus produce a sheet of uniform thickness from end to end of the rolls. lVith an instrument of this nature a sheet can be very easily and quickly gaged at each particular point on the rolls so as to detect any of the errors which might have resulted from the grinding.

The invention claimed is:

1. A measuring instrument consisting of a frame, a disk with a sharpened edge mounted on the frame and having Vits axis stationary with relation thereto, a roll with a flat edge connected with the frame and having its axis movable with relation thereto, the axes of the disk and roll normally being in alinement, and a gage carried by the frame and operatively connected to indicate the amount of movement out of alinement of the axis of the roll with relation to the axis of the disk.

2. A measuring instrument consisting of a frame, axles fixed to the frame, an axle movable along the frame, penetrating disks mounted upon said fixed axles, a surface roll mounted upon said movableaxle, and a gage carried by the frame and operatively connected to indicate the amount of movement of the axle of the surface roll with relation to the axles of the penetrating disks.

3. A measuring instrument consisting of a frame, a pair of rotary penetrating disks with sharpened edges mounted upon the frame, a slide movable along the frame, a flat faced roll rotarily mounted upon the slide, and a gage actuated by the movement of the slide to indicate the position of the roll with relation to the disks.

4:. A measuring instrument consisting of a frame, a sharpened rotatory disk mounted upon an axle fixed with relation to the frame, a broad edged roll mounted upon an axle movable along the frame, adjustable means for limiting the outward movement of said roll, and means for indicating the amount of inward movement of said roll with relation to said disk.

5. A measuring instrument consisting of a frame, rotatory means mounted upon the frame for penetrating the material to be measured, rotatory means yieldingly connected with the frame and designed to bear on the surface of the material to be measured, and a gage actuated by the movement of said yielding means to indicate the position of said surface means With relation to said penetrating means.

6. A measuring instrument comprising a handle, carrying sharpened rotatory disks adapted to penetrate the material to be measured, a rotatory roll With a broad pe riphery adapted to bear on the surface of the material to be measured, said roll being movable radially With relation to the disks, means adapted to adjust the relative positions of the disks and roll, and a gage actuated by the movements of the roll to indicate the amount of movement radially of theroll With relation to the' disks.

7. A measuring instrument having tWo connected frames movable With relation to each other, a spring thrusting between and holding said frames in normal relation, surface and penetrating rolls mounted on and carried by the respective frames, a dial gage fixed to one frame, and means iXed to the other frame and engaging said gage so as to cause it to indicate the amount of relative movement of the frames from normal position.

8.,A measuring instrument having a tubular frame, disks with sharpened peripheries rotarily mounted on the frame, a dial gage mounted on the frame, a slide fitted Within and movable longitudinally With relation to the frame, a roll With a broad periphery rotarily mounted on and movable With the slide, and means projecting from the slide and engaging said gage for indicating the movement of the slide and roll With relation to the disks.

9. A measuring instrument comprising a frame, rotatory means having a fixed position on the frame and designed to penetrate the material to be measured, means designed to bear upon the surface of the material to be measured, means whereby said surface bearing means is movable with relation to the frame,and a gage connected and arranged to be actuated by and to indicate the movements of said surface bearing means with relation to the frame and the penetrating means carried thereby.
