MEASURING DEVICE.

Application filed June 14, 1921. Serial No. 477,514.

of the United States, and a resident of Broken Arrow, in the county of Tulsa and- State of Oklahoma, have invented certain new and useful Improvements in Measuring Devices; 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. I

This invention relates to improvementsin measuring devices and more particularly to such as are adapted to register the amount of stitching done by sewing machines-one object of the invention being to provide simple and etficient means which may be readily attached to the head of a sewing machine and which shall be operable from the driving shaft therein to register. through the .medium of the rotation of said shaft and the number of stitches effected during each rotation. theamount of stitching accomplished in yards. feet and inches.

A further object is to so construct and arrange the mechanism of the device that two registers of the work done shall be made. one of which registers shall be visible to and controllable by the operator and the other concealed from view and inaccessible to the operator whereby any tampering with the visible registering devices may be detected by the readings of the concealed register.

With these and other objects in view. the invention consists in certain novel features of construction and combinations of parts as hereinafter set forth and pointed out in the claims.

In the accompanying drawings; Figure 1 is a view illustrating my improvements. with the casing shown in section: Figure 2, is a view taken at right angles to Figure 1: Figure 3 is a sectional view on the line. 33 of Figure 2: Figure 4 is a view in section on the line 44 of Figure 2. and Figure 5 is a View in section on the line 5 5 of Figure 2. i:

In describing the construction of my improved measuring device. I will assume by way of example that the sewing machine will make ten stitches per inch of the g'OOds and that the needle shaft will make three revolutions for each stitch.

A portion of the head of a sewing machine is indicated at l and the driving or needle shaft 2 is provided with a gear 9 which may be secured either to said shaft or to the fiy- 1 wheel 4;

A frame 5-is hinged at one edge to a plate 6 and the latter is adapted to be secured upon the head 1 of the sewing machine. A

shaft 7 is suitably supported by the frame 5 and at one end. this shaft is provided with a gear 8 to mesh with the gear 9 and has three times as many teeth as the latter so that the shaft 7 will make one revolution for each stitch. The shaft 7 is provided at its other end with a worm 10 which meshes with a gear 11 on a shaft 12.said gear 11 having 10 teeth so that it will make one revolution for each inch of stitching. The shaft 12 is also provided with a worm 13 which meshes with a worm gear 14 having twelve teeth so that it will make one revolution for each foot of stitching. The gear 14 is carried by a shaft 15 and this shaft also carries a gear 16.

The shafts of disk registers Aand B are mounted in the frame 5 and the shafts of these registers carry gears 1718 respectively and are spaced.apart,a portion of the gear 16 being disposed between the

gears

17 and 18. A bifurcated carrier 19 is pivotally mounted in the frame 5 and supports an elongated pinion 20 which may be made to mesh with the

gears

16, 17 and 18 so that motion will be transmitted from the gear 16 to both registers A and B simultaneously.

The register A may comprise four disks 0. 7), c. 07. The disk a represents inches so that one revolution of this disk will'represent one foot of stitching, this will be transferred to the disk 6 which represents feet. The disk 6 is provided with a plurality of sets of numerals 0 1 2 and when this disk I shall have been operatedthree times by the disk a, the disk 0 will be moved throug suitable transfer means one point,the disk c thus being intended to indicate yards, and the rotations of this disk 0 will, by suitable transfer means, operate the disk 03 which is intended to represent tens of yards. The disks of the register B have the same arrangement as the disks of the register A, but in the register B a greater number of disks may be employed (preferably six) so that a greater aggregate number of yards of stitching may be registered. The register B will be inclosed by a suitable cover B so that it will be inaccessible to the operator, while the register A is visible to the operator and capable of being set by him. The said register A maybe protected by a suitable covering havinga Window.

A shaft 21 is mounted in the frame and or disk 22 and after passing freely through an opening in the bottom of the frame 5,

is pivotally attached to the base plate 6. A rod 25 is connected at one'end to the de-- pending portion of the pivoted carrier 19 and said rod, after passing freely through a slot in the base of the frame 5, ispivotally attached to the base plate 6. -It will be observed that by turning the manually 0-perablc shaft 21 the frame 5 will be moved on its'hinged connection with the base plate 6 and the gear 8 will be moved out of mesh with the gear 9, thus disconnecting the de-- vice from operative relation to the needle shaft of the machine. It will also be observed that when the frame 5 is thus tilted, the carrier 19 will be turned on its pivotal mountin and the elongated pinion 20 will be moved out of mesh with the

gears

16, 17 and 18, thus rendering the registering mechanisms inoperable.

'VVith the use of my improvements, duplicate registers of the number of yards of stitching done by the sewing machine will be made, one ofsaid registers being inaccessible by and out of view of the operator of the sewing machine so that should such operator tamper with the visible register, such tampering would be denoted by comparing the readings of the latter with the readings of the other register.

Having fully described my' invention what I claim as new and desire to secure by Letters Patent, is: A

1. In a registering device, the combination of a frame, two similar registers mounted therein, one of said registers being visible to the operator and the other register being concealed from view of the operator, means for actuating said registers simultaneously, and means for disconnecting the actuating means from said registers, whereby one and only one of said registers maybe actuated independently.

2. In a device of the character described, the combination of a frame mounted for swinging movement, similar registers mounted within' the frame, means whereby one of said registers is made visible and the other a concealed from view of the operator, a carrier pivotally mounted in the casing adjacent the registers, a pinion mounted in said carrier and adapted to operate both registers, and means whereby swinging of the frame will cause the carrier to move the pinion to or fromthe registers.

3. In a device of'the character described, the combination of 'a base, a frame mounted on the base for vertical swinging move- 1nent, a register mounted in the frame, a carrier pivoted in the frame, a pinion on said carrier to actuate the register, and a rod extending through the bottom of the frame and pivoted at one end to the base and at its opposite end to the lower end of the carrier.

4. 111 a device of the character described, the combination of a base, a frame hinged at its rear side upon the base, a shaft mounted in the frame and operable from the exteriorthereof, a crank on said shaft, a rod extending through the bottom of the frame and pivoted at one end to said crank and at its opposite end to the base, a register in-the frame, and a pinion'arranged to actuate the register and movable to or from the same by the swinging of the frame.

In testimony whereof, I have signed this specification in the presence of two sub scribing witnesses. i p SIDNEY LEE,
