ABRAHAM L. TOLHAN AND FRANK L. TAYLOR, OF ORANGE, MASSACHUSETTS, ASSIGNORS 'lO NOVEL IDEA COMPANY, OF ORANGE, MASSACHUSETTS.

DEVICE F633 MAKING- DESIGNS.

Application filed July 15,

To all whom it may concern:

Be it known that we, ABRAHAM L. TOL- MAN and FRANK L. TAYLOR, citizens of the United States, residing at Orange, in the county of Franklin, State of Massachusetts, have invented a new and useful Device for Making Designs, of which the following is specification.

This invention relates to machines of that class employed for making fanciful scroll designs, and operates generally on the principle of a geometrical lathe, the pencil, pen, or stylus being so mounted and operated as to trace various designs on paper, slate, or other surface.

The principal object of the invention is to provide a machine of very simple and economic construction which may be readily operated by'a child, and which may be also employed by engravers or others in the production of fanciful scroll work.

A still further object of the invention is to provide a machine in which all of the moun t ings may be readily adjusted for the purpose of changing the character of the design produced, and further to so arrange and con struct the operating mechanism that the support for the paper or other surface may be revolved at difierent speeds and in different directions.

With these and other objects in view, as will more fully hereinafter appear, the invention consists in certain novel features of construction and arrangement of parts, hereinafter fully described, illustrated. in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that various changes in the form, proportions, size and minor details of the structure may be made Without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawings :Figure 1 is a perspective view of a machine for making designs constructed in accordance with the invention. Fig. 2 is a side elevation of the device, parts being broken away in order to' more clearly illustrate the same. Fig. 3 is a detail perspective view of the pencil or stylus carrier showing the various parts detached. Fig. 4 is a detail view of the holding clamp for the pencil carrier. Fig. 5 is a detail section through the crank pin and its connections.

Specification of Letters Patent.

1908. 1 Serial No. 443,731.

Similar numerals of reference are employed to indicate corresponding parts throughout the several figures of the draw ings.

The working parts of the machine are supported by a suitable frame, which in the present instance comprises a pair of wooden or metallic strips 10 and 11 which are connected by a table or platform 12.

The table 12 is provided with bar openings for the reception of a pair of vertical shafts 15 and 16. To the upper end of the shaft 15 is secured crank disk 17, the periphery of which is grooved to form a driving pulley, and to the lower end of the shaft 15 is secured a smaller driving pulley 18. To the upper end of the shaft 16 is secured a disk 20 that is provided with a grooved periphery which may be made to receive a belt so that it may be driven from the disk 17, and the belt may be crossed or straight in order to revolve the disk 20 in either direction. To the lower end of the shaft 16 is secured a grooved pulley 21 which is shown as connected to the small pul ley 18 by a cross belt 22 so that movement is imparted from the shaft 15 to the shaft 16 at a comparatively low rate of speed.

Extending diametrically across the top of the disk 17 is a pair of spaced guiding strips 24 which serve for the reception of a slidably adjustable bar or plate 25 to which is secured the lower end of a crank pin 26. The upper end of the crank pin is turned outward to form an operating handle that is provided at its outer end with a small revoluble knob 27. The lower portion of the crank pin 26 is threaded and receives a clamping nut 29, which when turned down engages again st the top of the guides 24 and locks the plate 25 in place; by loosening the nut the plate may be freely shifted within the guides in order to adjust the distance of the crank pin from the axis of rotation of the disk.

Mounted on the threaded portion of the crank pin is a nut 30 which forms a stop for limiting the downward movement of a collar 31 that is guided on the pin, and said collar is I normally depressed by a spring 32 the upper end of which bears against a fixed collar or flange 33 carried by the crank pin.

Extending from the collar 31 is a stylus or pencil supporting arm 35. This arm is formed of two sections, one of which is prefl erably made of sheet metal and bent into the ing bar is a slide 42 from which projects a "clip 43 adapted to carry form of a sleeve for the reception of a rod 36,

the outer end of which is turned to form an eye 37 that fits over a vertical pin 38 carried by an adjustable slide 39. The slide 39 is 1 made of sheet metal, and its opposite sides are inwardly crimped to engage the grooves I that are formed on the opposite sides of the upper portion of the bar 11. The slide is 1 preferably made of metal of a more or less elastic nature so that it will hug closely to the j side of the bar 11 and retain its position without the necessity of employing any auX- l iliary securing devices. Surrounding the pin 38 is a helical compression spring 40 that tends to force the rod 36 downward.

. l Mounted on the section 35 of the connectl a pencil, pen, stylus, or other marking device. The stylus carrier is firmly clamped in position by an auxiliary spring clamp that is provided with a pair l ofoutwardly projecting wings 46 for conl venience in opening it to release position so l that the stylus carrier may be freely moved l along its carrying rod.

The disk 20 is arranged for the reception of a marking surface such for instance as a piece-of paper or slate or metal having a prepared surface to be engraved. or etched.

In operation the paper or other marking I surface is secured on the disk 20 and the stylus carrier is adjusted to the desired l point in the length of the connecting rod 35. The position of the crank pin is then adi justed and the slide 39 is shifted to the required point. The crank pin is then revolved by grasping the knob 27. The outer end of the stylus carrying rod will swing on l the pin 33 while that end connected to the crank pin which is the pin. The stylus carrier will thus be made to travel in an approximately ovate l path, and as the disk 20 is revolving the l determined by the adjustment 0 line described by the stylus will be in the form of a continuous scroll.

Owing to the various adjustments the l stylus may be made to travel in many dis tinct lines to produce scroll work of different l patterns, and various geometrical figures the l appearance of which may be varied by employing pencils or other marking devices of j different colors. 2
