MARKING DEVICE.

Specification of Letters Patent.

Patented Aug. 31, 1920.

Application filed February 20, 1920. Serial No. 360,033.

To aZZ whom it may concern:

Be it known that I, lVAL'rnn T. Snrrz, a citizen of the United States, and resident of Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Marking Devices; and I do hereby declare the following to be a: full, clear, and exact description thereof.

My invention relates to devices for marl ing designs upon cloth and other materials, and it has for its object to provide a marking device by means of which circular designs may be quickly and accurately producod.

In stamping designs upon linenpreparatory to embroidering, it has been a difficult matter to produce satisfactory circular designs, since the ordinary methods of applying such designs produce a result that either is not perfectly circular or does not match accurately at the point where the marking begins and stops. In particular, these difficulties are experienced by inclividuals who attempt to mark their own designs for embroidery and other forms of needlework.

According to my present invention, I provide a simple marking device by means of which circular designs of any desired pattern may be quickly applied without special skill. This device consists, in general, of a rotary wheel carried at the outer end of a rotatable support, the radial length of which is adjustable at will. This adjustable support preferably consists of a rod extending through a freely rotatable pivot member and held in place therein by means of a setscrew or the like. The rod may suitably be formed in a plurality of sections which may be joined together end to end to pro- .vide a wide range of adjustment formarking patterns of different diameters.

For a more detailed description of my invention, reference may be had to the accompanying drawing, in which Figure 1 is a perspective view of my device, showing one method of varying the'length of the radius arm; Fig. 2 is a plan view of the same device; Fig. 3 is'a vertical sectional view of the central support; Fig. 1 is a transverse vertical sectional view of the marking wheel; Fig. 5 is a side elevational view of the marking wheel; and Fig. 6 is a perspective view of a modified. form of yoke for the marking wheel.

In the drawing, the numeral 2 represents a base member which carries a freely rotatable pivot member 3 that is secured to the base by means of a pin 1 and a nut5. The pivot member 3 is also provided with a knob 6 and with a transverse opening 7 through which extends a radius rod 8 thatis secured in its adjusted position within the opening 7 by means of a set-screw 9. The rod 8 is made up of a plurality of sections, suitably of brass tubing or the like, one end of each section being tapped, as shown at 10, to receive a screw-threaded pin 11 carried by the end of the next section.

Secured to the outer swinging end of the rod 8 is a rotary marker comprising a yoke 12 provided with a tapped seat 13 to receive the screw-threaded end of the rod 8, and also provided with a knob or handle 14 and with openings 15 to receive an arbor 16 upon which is mount-ed a wheel 17 having a rubber rim 18 upon which is formed a suitable design, as shown at 19. The arbor 16 is provided at one end with screw-threads 20 and at its other end with a thumb nut 21. An inking roller 22 is carried on a pivoted yoke 23 above the marking wheel, and is pressed into engagement with the wheel by means of a spring 24.. In order to hold the inking roller out of contact with the marking wheel when the wheel is not in use, so that neither the roller nor the rim shall be deformed by long standing in contact, I provide a spring-finger 30 secured to the yoke 12 and adapted to engage beneath the yoke 23 when the roller is raised, and also adapted to be pushed aside to allow the roller to descend into engagement with the marking wheel. The rod 8 may, if desired, be provided with graduations or grooves 8,

.whichmay either indicate inches or fractions of the circumference of the marking wheel. -The wheel itself is preferably provided with a mark 31 for indicating the proper starting and stopping point with reference to the pattern on the wheel.

In order to provide for marking different patterns, a number of interchangeable marking wheels are supplied with each device. The pattern rim for each of the wheels is preferably made with an embedded reinforcement, suitably of wire mesh, to prevent the rim from stretching while the wheel is in use.

When it is desired to provide my device with pattern wheels of different diameters,

and especially for marking large patterns, the yoke may be made as in Fig. 6, where the yoke is shown as having guides 25 between which is clamped a block 26 secured to the end of the radius rod 8 and having a threaded pin 27 that extends through a slot 28 in one of the guides 25. The block may be fastened at any point of vertical adjustment by means of'a knurled nut 29, so that marking wheels of various diameters may be used with the same yoke and central base.

In marking circular designs with my device, the arbor 16 is unscrewed from the yoke, and the marking wheel carrying the desired pattern is slipped over the arbor and the arbor is replaced in the yoke. The inking roller is then lowered upon the marking wheel, and the length of the radius rod is adjusted to the proper radius of the circle that is to be marked. For this purpose, it is convenient to make use of a sheet of paper for marking out a trial design and making any small adjustments of the radius rod that may be necessary to cause the pattern to match at the point where the design begins and stops. When this adjustment has been made, the base 2 is placed on the center of the sheet of cloth or other materialto be marked, andv the design is quickly applied by setting the wheel with its guide mark in contact with the cloth and then revolving the arm carrying the marking wheel around its pivot. The square form of the central base member 2 enables the base to be quickly centered on the sheet by connecting the corners of the sheet by straight lines or threads, and placing'the base member at the intersection of these lines, with each corner of the base touching one of the lines.

It is evident that as many copies as desired may be made of each pattern, and also that the number of different patterns that may be marked, and the diameters of the circles, are limited only by the number of different .marking bands that are supplied with the device and by the length ofithe radius rod 8. I find it convenient to provide sufiicient sections. of the rod to produce a maximum marking diameter of54l inches, which is the largest diameter in which circular designs are commonly employed, but the rod may be made in any desired length, either greater or less than 54: inches.

My device is of special advantage in marking designs upon piled fabrics, such as velvet, the'loose surface of which has made it ,difiicult to apply designs in regular patterns by the methods'heretotore employed.

My deviceis of course not limited to the use of any particular design or series of designs, and it may be employed for various purposes other than the marking of embroid ery linen. For example, patterns for gear wheels and other curved machine parts may be quickly and accurately laid out by providing the marking wheel with the necessary outlines.

It is also to be understood that numerous changes in the construction and arrangement of parts may be made without departing from my invention, and I therefore desire that no limitations be imposed upon my invention, except such as are indicated in the appended claims.

What I claim is:

1. A marking device comprising a rotary marking wheel and 'means for revolubly moving the said wheel in a circular path.

2. A marking device comprising a rotary marking wheel and means for manually moving the said wheel in a circular path of adjustable radius.

3. A marking device comprising a rotatable and radially adjustable member, and a marking wheel carried by the said member.

4. A marking device comprising a rotatable and radially adjustable rod, and a marking wheel carried at the end of the said rod.

'5. A marking device comprising a rotatable and radially adjustable sectional rod, and a marking wheel carried at the outer end of the said rod.

' 6. A marking device comprising a base, a freely rotatable pivot member carried thereby, a rod adjustably secured to the said member and a marking wheel carried by the outer end of the said rod.

7. A marking device comprising a rotary marking wheel and a support for revolving the said marking wheel in a circular path, the said wheel being movable upon the support eccentrically with respect to its axis of rotation.

8. A marking device comprising a rotary marking wheel, an inking roller forithe said wheel and means for holding the said inking roller out of contact with thesaid marking wheel when the said wheel is not in use.

.9. A marking device comprising a base member, a pivot member mounted thereon and provided with a set-screw,- a rod extending through the said pivot member and adapted to be secured in. position by means of the said set-screws, a marking wheel car ried at the outer end of the said rod, and an inking roller for supplying ink to the said markingflwheel.

In testimony whereof, I, the said WALTER T. Smrz, have hereunto set my hand.
