CLOTH COMPUTING AND IVIEASURING MACHINE.

SPECIFICATION forming part of Letters Patent No. 580,862, dated April 20, 1897. Application led January 26, 1897. Serial No. 620,822. (No model.)

To all whom it may con/cern:

Be it known that I, OTTO HECKEL, of St. Louis, State of Missouri, have invented certain new and useful Improvements in Wire- Oloth Computing and Measuring Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates to improvements in a wire cloth computing and measuring4 machine; and it consists in the novel arrangement, construction, and combination of parts, as will be more fully hereinafter described, and set forth in the claims.

The object of my invention is to construct a device in which a roll of wire-cloth or screening or other material may be placed, and by unwinding the same from this device it measures the length desired and calculates the number of square feet and gives the amount it will cost, according to the manipulation of the roller, which will be fully hereinafter set forth. In this device any width of cloth or such material may be applicable, and according to the graduations upon its computing-roller it will designate to a fraction what the cost of the different widths will be at so much per square foot. This can be instantly read from the face of the roller and the faceplates.

This invention has proven a wonderful time-saving device, as, for instance, in all stores the clerks are compelled to figure, first, by measuring the article with a rule; second, to figure out the square feet in this length, and, third, to figure out lthe cost at so much per square foot. All of this is unnecessary when using my device, as the calculating and measuring are done by simply withdrawing or unrolling the material through this device. The lineal measure is designated upon the graduated disks located at each end of the machine, and the square measure and price are designated upon the computing-roller.

Referring to the drawings, Figure 1 is a front elevation of my complete invention. Fig. 2 is an end view of the same, showing a portion of itself tilted in dotted lines. Fig.

5o 3 is a vertical sectional elevation taken on the line 3 3 of Fig. 1. Fig. 4 is a verticalsectional View of the chamber carrying the operating mechanism, taken on the line 4 4 of Fig. 5. Fig. 5 is a vertical sectional view taken on the line 5 5 of Fig. 4. Fig. G is a front view of a portion of my device to an enlarged scale. Fig. 7 is a face view of a portion of the computing-roller detached from the machine, showing the method of gradnation.

In the drawings, 1 indicates my complete invention, which consists of a base 2, made of any desired material, and to each side of said base 2 is mounted a curved casting 3. Upon the base 2, from casting to casting, is mounted a table 4, over which the material to be unwound is passed. To the ends 5 of the castings 3 is pivotally mounted a frame 6, which is composed of two chambers 7 and 8, and are held together at the top and bottom by rods 9, which may be constructed in any desirable manner. At equal distance between the rods 9 and passing through said chambers 7 and S is a shaft 10, upon which are mounted disks 1l, one on each end and an indefinite number between, according to the desire of the manufacturer. Over these disks ll is secured, in any desirable manner, asheet of Celluloid 12 or other suitable material, and upon this sheet is placed the computingscale.

Upon the shaft 10 and within the chamber Sis mounted a double gear-wheel 13, provided at its one side with a double collar 14, acting as a guide for said wheel, keeping same in its position. To each end of said shaft 10 is mounted a disk 15 and 16, upon which are imprinted numbers and graduations from 1 to 25, but any number of figures and graduations may be imprinted thereon as desired, according to the size of said disk. Each of these graduations represents one lineal foot.

The disk 15 is in communication with the gear-wheel 13 by means of friction caused by a rubber ring 16 or other iexible material placed upon the shaft 10 between the disk 15 and shoulder 14 of the wheel. By this friction the shaft 10 is revolved, as the gear-wheel 13 is loosely mounted thereon, and the disk 15 is secured to the shaft by a set-screw.

Beneath the double gear wheel 13 and mounted upon a shaft 17, held by the sides of IOO the chamber 8,is a double gear-wheel18, meshing with the gear-wheel 13, and beneath the double gear-wheel 1S and meshing with the smaller portion thereof is a gear-wheel 19, provided with a double collar 20, and is loosely mounted upon a shaft 21, said shaft 21 being also provided at each end with a disk 22 and 23, said disks graduated and numbered from 1 to 12,signifying inches.

Between the disk 22 and the collar 2O of the wheel 19 is also a friction-ring 24:, similar in construction and purpose to the one 16 previously described.

Beneath the wheel 19 and meshing therewith is a gear-wheel 25, rmly secured to a shaft 26, and upon said shaft is mounted a roller 27, the operation of which will behereinafter fully set forth.

To the opposite end of the shafts 10 and 21 and between the outer casing of the chamber 7 and the disks 16 and are spiral springs 2S, which are for the purpose of keeping the collars 14 and 20 in close operative communication with the disks 15 and 22.

On the chambers 7 and 8 are mounted pointers 29 and 30. Upon the pointer 29 is im'- printed the word Inch and upon the pointer 30 is the word Feet. Also upon the disks are pointers 31-and 32. These are provided with the abbreviations of feet and inches, the pointer 31 provided with 111. and the pointer 32 with Ft In the rear of the computing-roller and secured to each chamber is a guard 33. This is for the purpose of preventing the material being unrolled from coming in Contact with and scratching the celluloid covering of the computing-roller.

In front of the roller and secured to the chambers are graduated face- plates 34 and 35. The upper or plate 34 is provided with graduations of any desirable number, and within each graduation is the word \Vidth, and each has also a number designating the widths of material being unrolled.

The plate 35 has graduations corresponding with those upon the plate 34:, and within its graduations are the words Sq. feet and Sell.

The computing-rollerlhas its graduations divided to correspond with the plates. Thus the figures that come in view between the two plates signify as follows: Those appearing over the space occupied by the words Sq. feet indicate the amount of square feet in the piece withdrawn from the machine, and the figures appearing over the space marked Sell indicate the cost or selling price of the piece containing the amount of square feet shown.

To the curved castings 3 are mounted bars 3G, forming a support for the roll of material placed within the space 37, as shown by dotted lines in Fig. 2, the lower three bars acting as rollers, allowing the roll of material to revolve thereon when being unwound.

Any desirable width of roll may be placed within the space 37, the device being so arranged, permitting the ends of the roll to eX- tend beyond the ends of the device.

The operation of myinvention is as follows: Vhen the device is in operative position upon a table or counter and it is desired to place the roll of material within the device, the frame 6 is then raised, as shown by dotted lines in Fig. 2, the end of the cloth is brought to the outer edge of the table 4, and then the frame 6 is lowered, permitting the roller 27 to rest upon the material, and is kept in close contact therewith by means of the frames gravity. The disk 15 is then pulled upon, as shown in dotted lines in Fig. 5, releasing the friction-rin g from the wheel 13, and then the disk is turned so that itsblank-mark is in line with the pointer secured to the side of the chamber. Vhen the disk is released, the action of the spiral spring on the opposite side of the device places the friction-ring again in operative position. The disk 22 is also manipulated in like manner as the one just mentioned. When the cloth is being pulled from the machine, it operates the roller 27, which turns the gear-wheel 25, this wheel turning the gear-wheel 19, which revolves the shaft 21 and disk 22, which indicates inches, this wheel meshing with a wheel 18, which is in communication with a wheel 13, which operates the computing-roller and disk 15, indicating feet. The gearing is so constructed that by the revolving of the roller 27 the disk 22 revolves, each round indicating-one foot, while the disk 15 revolves but from one mark to the other, each mark indicating one foot. Thus the disk 22 is revolved twenty-five times to once of the disk 15, this giving the lineal measure. The square feet and selling-price are found upon the computing-roller, as before clearly mentioned.

Having fully described my invention, what I claim, and desire to secure by Letters Patent, is-
