SPECIFICATION forming part of. Letters Patent No. 473,892, dated April 26, 1892.

Application filed April 3, 1890, $erial1lo, 348,373- (No model.)

To all whom it may concern.-

Be it known that I, AUGUSTUS G. BURTON, of Chicago, in the county of Cook and State of Illinois, have invented certain new and usefullmprovements in Machines for Measuring the Thickness of Leather; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being bad to the accompanying drawings, and to theletters of reference marked thereon, which form a part of this specification.

This invention relates to improved devices for measuring the thickness of soles, insoles, taps, and general stock for boots and shoes.

The special object of the invention is to produce a machine by which every portion of the leather or other material, instead only of its marginal edge, may be measured or sized.

To this end the invention consists in the construction herein illustrated and described,

' and more particularly pointed out in the appended claims.

I have shown in Figure 1 a perspective view of a machine embodying my invention. Fig. 2 is a plan view of the same. Fig. 3 is a front elevation of the same, a portion of the front plate of the housing being broken away. Fig. l is a side view of the same with a portion of the housing broken away. Fig. 5 shows a slightly-modified form of a portion of the device.

In the said drawings, A represents the table or base-plate of the machine, which is firmly secured by screws or or other convenient means to a table or standard A.

A is a vertical standard or part, preferably cast integral with the base A at its rear portion. An arm or bracket A is preferably cast integral with the standard or back A and extends over and toward the front end of the base-plate A, so as to leave a space a between the lower edge of said arm or bracket A and said base-plate. The forward end of the base-plate project-s beyondthe table or support A and is provided wlth a slot or elongated opening therein a Depending lugs a extend downwardly from theforward end of the base-plate A on either side of the said slot or opening a and in said lugs a is suitably journaled a spindle or shaft ed. A

roller A is mounted upon said spindle a so as to extend through the opening a and rise some little distance above the upper surface of the base-plate A. This is the preferable construction, although some of the advantages 5 5 of my invention may be obtained by the modified form shown in Fig. 5.

The housing B is placed upon the frame A and adjacent to the vertical standard A which latter forms the back of the housing. The face-plate B of said housing is provided with an upper portion 1), which is relatively larger than the housing B, and which projects above it, preferably in semicircular form, as clearly shown in Figs. 1 and 3. tire lower portion of the face-plate B of the housing does not extend to the base-plate A, but is cutaway at b b, so as to pass around and escape the bracket A as more clearly shown in Fig. 1.

\Vithin the housing and revolubly secured to the inner surface of the back plate or standard A is a pinion C, the stem 0 of which projects through the face-plate B and is secured to the shank of an index-finger B whereby said finger is moved by the rotation. of said pinion C. t

C is a segmental lever, pivoted at 0' within the housing to the back plate A so that its teeth 0 will mesh with the cogs of the pinion C.

D is a lever pivoted at d to the bracket A The forward end of this lever D is provided with a roller D, revolubly secured thereto in position directly above the roller A 7 The long arm of the lever D projects into ,the housing B and there engages the lower and slotted portion of a link E, the upper endx of which is pivoted at e to the segmental lever C at a convenient point between theteeth 0 and the pivotal connection 0'. The end (1 of the lever D is smaller than the slot 6' in the lower end of the link E. The free end of a leaf-spring 01 secured near the end of the long arm of the lever D, is inserted in the 5 upper portion of the slot 8 and tends to throw the end cl of the lever into the lowermost portion of said slot. An adjusting-screw e is passed through the lower portion of the link E and against the undersurface of the end d This en- 65 a graduated scale B of the lever D for the purpose herinafter mentioned.

d d are pins or stops standing at right angles from and secured to the bracket A for the purpose of limiting the downward and upward movements, respectively, of the long arm of the lever D.

F is a spring, one end of which is suitably secured to the lower end of the link E and the upper end being suitably secured to a lug f on the standard A". Said spring F tends at all times to draw the said link E and the end d of the lever D upward, and to cause the long arm of the lever D to normally stand against the stop (1 and the index-finger'B to normally point to a given mark upon the extended portion 1) of the face-plate B.

Upon the outer edge of the face-plate B is Any scale of course may be adopted; but in the present instance I have illustrated a scale representing fortyeighths of an inch at each division-mark. For instance, the first mark will indicate four forty-eighths, the second five forty-eighths, the next six forty-eighths of an inch, and so on. When the arm D is in normal position to wit, as shown in Figs. 1 and at, with the spring F exerting its maximum strength the index-finger B in the present instance should point to the division-mark four fortyeighths on the scale B this meaning that the distance between the peripheries of the rollers D A at their most adjacent points is four forty-eighths of an inch. It may sometimes happen, however, that the spring F will not be so located as to normally bring the index-finger B to the desired position, and hence the adj listing-screw e and spring at are used, the latter to prevent any lost motion or slackness between the end of the arm D and the I lower end of the link E and the former to correctly adjust the normal position of the index-finger B so that the-spaces between the rollers D and A shall exactly correspond with the distance indicated on the scale, as will be readily understood.

The bracket A is provided at its outer end with an extended portion or arm A (See Fig. 2.) The short arm of the lever D is provided with a lug d 011 the side adjacent to the arm A which lug bears against the face a of the arm A. usually inserted between the rollers D and A from the side opposite to the arm A and this arm therefore serves to take a part of the strain off the arm D, and thus prevent the latter from losing its adjustment.

In operation my device is very simple. The piece of leather to be measured or sized is passed between the rollers D and A as shown in Fig. 3, in such manner that the rollers may revolve. The upper roller D of course will yield, the rear end of the lever D, to which the roller D is attached, will be depressed, and the index-finger B will be carried around the scale B to such position as to indicate thereon the number of forty-eighths of an The goods to be measured are inch between the rollers D and A. It will such length as to permit pieces of leather of such size as are usually applied to the soles of shoes and boots-to be passed freely therethrough and all portions thereof correctly sized or measured.

It is not necessary and may not always be desirable to have two movable surfaces for the leather to be passed between, as one of said surfaces may be movable and one stationary. Such a construction I have shown in Fig. 5, wherein the roller A lugs (17 a and slot a are removed and an uprising lug a, having a rounded upper edge, is placed upon the base-plate A under the roller D.

What I claimis 1. In a machine for measuring the thickness of leather, the combination, with a suitable frame having a scale marked thereon, of a support for the leather attached to said frame, a lever pivoted to the frame having a roller secured directly to one end thereof in position above the support, an index-finger for the scale pivoted to the frame, and a suitable connection between the end of the lever opposite the roller and the index-finger, substantially as described.
