Application led December 2e, 1915. Serial No. 68,495.

Be it known that I, FiiANcrs Sram- KAMP, a citizen of the United States, resid- 'ing in the city,` county, and State of New York, have invented certain new and useful llmprovements in Designcgraphs, ofU which the following is a speciication.

My mvention relates to a desiffnograplrof the class including devices or tracing curved designs on-paper and the primary object ofthe invention is to provide a simple form of device for mechanically tracing numerous types of curves having a greater degree of complexity than is possible `with devices of this class now in general use.

My invention broadly includes a toggle f arm-type ofpencil con-trol, one or both arms of 'which-are designed to be subjected to variable controlling iactors4 which thus cause a complexity of control resulting `in the formation of both closed and open curves of a great variety of design.

A further object of my invention is to provide a device .of the class described in which the relation of one of, the controlling members to the other may bequickly and accuratelyv varied in its controlling 'el'ect and in accordance with some set plan without aiecting the'operative position of said controlling elements.

l attain this object broadly notvonly by varying the constants which control one or an inspection of the accompanying drawin yboth arms of the togglev pencil cntrol but also by varying thexangular` adjustment of the tracing table with reference to its engagement with the mechanism which con` trois the toggle.

Another object of my invention. is to provide a device for simultaneously causing a y lnrality of simlardesigns to be arranged in present relation to each other.

lncidentally, the device illustrated is intended to be assembled as one of the possible constructions which can be made-from the.

parts Yconstitutingl the steel structural elegjf'ments'of a mechanical toy including perforated girderstripsgand pl`atestwo types of which are known commercially as Mechano and American lmodel builder.

Variousdother objects and advantages of v the invention will be in part obvious from vmeans of vertical struts 12 all coactin arranged to form an-opcn box-like trame for supportingB the movable parts of the device. Both the superframe and the underlframe are formed of longitudinally and transverselydisposed side members 13 each and in part will be more fully set forth in the following particular description of one form `of mechanism embodying my invention, and the invention also consists in cer- Snecication of Lettera Patent. V- Patented dan. 15, ilgls l tain new 'and novel features of construction and combination of parts hereinafter set forth and claimed.

In the drawings: v

Figure 1 is a plan view of a preferred embodiment of myinvention showing` the table supporting frame in an adjusted dot and dash line position; and

Figs. 2 and '3 are 'respectively side and shown an open-work main supporting frame formed of a rectangular super-frame 10 and a similarly shaped underframe 11 with these 4vend views in elevationl of the device shown in Fig. 1.'v ln vthe accompanying drawings, there is' frame elements connected at each corner by l and provided with` vertically alined pivot-pin holes 14 equally spacedA apart along-the -length ofl each of the side members and de'- signed to receive one or more pivot pins 15. rlhese pins are designed to be inserted in any pair of holes! andare ,held in position with their upper .ends projecting above lthe side members forming the superframe by'means of stop collars 16 adjustably mounted on the upwardly projecting portlon of the pivot pins. A work supporting table 17 is centrally mounted for rotary movement within the frame and in a plane substantially on a level with the superframe. The table is ar .raiiged to receive the paper or other work upon which the design is to be made. The

table and its driving mechanism are arranged to be supported from a, table frame 18 shiftably mounted in the main supporting` frame. rll`he table frame is vertically disposed and includes upper and lower longitudinal members 19 and 20 corresponding in shape to the side members of the main frame. The ends of each of the members 1.9 and Q0 are adjustably fastened, by means of readily removable pins 21 respectively toi suiiicient for both it being understood that porting` frame any of the holes 14 in the upper and lower frames. These members are preferably braced in spaced apart relation to form a unit frame by means of the vertically extending struts 22 fastened therebetween. The members 19 and 20 are provided with spaced apart holes 23 resembling the holes 13 and the struts are fastened to these members by'rneans of screws 24 passed through one of the holes and into the ends of the struts. A vertically disposed driving shaft 25 is rotatably mounted in any of the vertically. di'sposed pair of holes 23 and is driven through the beveled gear connection 26 from the longitudinally extending shaft 27 rotatably mounted in the struts 22. This shaft is in turn driven from the main driving shaft 28 journaled in the struts 12. An outer end of the main shaft is .provided with a crank handle 29 by means of which the main shaft and parts operated thereby may be driven either`in a direct or reverse direction. The connection between the main shaft 28 and the longitudinal table driving shaft 27 is preferably in the-form of a friction drive 30. This drive includes a driver in the form of a disk 31 fixed to the main shaft and a round headed driven member 32 fixed to the shaft 27 in operative engagement with the disk to bedriven thereby. The member 32 is adjustable relative to' the axis of rotation of the disk 31 to vary the rotary speed of the table and for this purpose the shaft 27 includes a turn-buckle 33 thus providing a convenient means for varying the speed of the design table with reference to the speed of the main shaft and the pencil control actuated thereby. The' design table'proper is formed of a fiat metal disk 34 loosely mountedon top of the shaft 25 and a wooden plate 35 fixed to the upper face of the disk and designed to have the paper 36 fastened thereto by any suitable means, such as thumb tacks 37. A driving connection is provided between the shaft 25 and the disk 34 by means of an arm 38 xed to the shaft 25 and provided with a spring catch 39 designed to engage in any one of a plurality of centrally disposed apertures 40 arranged concentrically of the axis of the disk 34 and on the under side of the disk.

' A pair of recording tables 41 and 42 are mounted in adjusted position on the supand are operatively driven from the main shaft 28.' A description of either one of these recording tables will be the two tables may be mounted either on the same side of the lmain frame or one on one side and the other on either the opposite or an adjacent side of this frame. Each of these recording.'l tables includes a vertically extending shaft 43 adjustably mounted in any of the pair of holes 14.. A disk 44 is and above ,screws 58 to the levers.

the superframe 10..A A slide bar 45 is adjustably mounted on the disk 44 and is fixed tion of the table 41. The shaft 43 is connected to the main shaft so as to be driven thereby preferably by means of a mitered gearconnection 48. This gear connection is preferably so arranged that` raising the shaft 43 with its revolving pivot pin 47 will break the connection between the teeth of the gears forming the connection thus permittinn' either the main shaft or the record table driving shaft to be adjusted relative to each other.

Further thespeed between the recording table and the main shaftmay be varied by varying the speed ratio of gears making up the connection 48. In this way it is possi-ble to cause the rotation ofthe recording table to be a definite function of the rotation of vthe work-table or a definite function of the other recording table. The placing of the design on the paper is controlled by means of a toggle pencil control formed of arms 49 and 50 pivotally connected at any point along their lengths by means of a pin 51. Each of the arms is provided with openings 52 corresponding in character to the holes 13 and each designed to be engaged either by both of the revolving pivot pins 47 or arranged so that one of the holes in one of the arms is engaged by one of the revolving pins 47 and one of the holes in the other arm is engaged by one of the fixed pins 15. The

Vpencil control includes a pencil carriage including a bracket 53 of the pivotal connection between the arms.`

A pair of levers 55 are pivotally connected side by side to an upstanding member 56 of the bracket and designed tobe adjusted vertically about horizontally disposed axes of rotation. Each of the levers is provided with a pencil band 56 designed to encircle a pencil 57 or other suitable marking device. The bands are attached by means of adjusted into frictional tight engagement with the lever and band so that the pencils vmay be adjusted to assume any desired angle withreference to the vertical or'the screws may be used merely as pivots in which case the pencil is held` to the paper merely by lts ownweight land the weight of the The screws. may be reference to the design table.

` the same frame into position to dispose the j Leagues sired Vto make a definite character'of curve,

the resultant of two movements, one an oscillatory movement abolita fixed center and the other an oscillatory movementabout a center which is itself revolving, .one of the arms is placed on the pin 15 which has been shifted in the frame into positionto bring the pencil at the desired starting point with The other arm is placed upon one of the pins 47, the driving shaft of which has been adjusted in pencil at its desired place on the work toggle arms. The main shaft is then rotated, causing either or both of the pencils, depending upon the arrangement of the arms carried by th'bracket to form one'or two similar tracings on the paper 36. Should it be desired however, to form a character of curve -the resultant of compounding ino-' l the iixedxpin 15 is shifted to the `pin 4 of the other recording table, and the operation is repeated as previously, described but.

obviousl giving -a more complex curvel By movin@r the catch 39 into an inoperative position, tius disconnecting the work-table from its driving shaft, the table may be rotated upon .the axis of the shaft into any angular desired.y position. 1n this reset position` the catch may be reset to hold' the table in connected drivin relation with the mechanism controlling t e pencil control. r1`he table may be reset to rotate about a new axis of rotation byA loosening one or thel other of the pins at the opposite ends of the table frame, andA adjusting the same so that the table frame will be in a new position with reference to the main frame. It is pos- 'is possible-to design an ever-interesting toy sible to make this adjustment without 'affectingvthe driving connection between the main shaft and the` horizontal'table driving shaft due to the rounded construction 'of the head to the driven member 32. By adjusting the turn-buckle the speed of the work table with reference to the cycle of operaltion of the togglevpencil control may be carv from structural parts supplied by the structural mechanical element toys lnow in general use. Practically an unlimited number of beautiful and unusual designs may be toggle controlling member alon formed simply by varying the positions of l the toggle arms and a control for the pencil is provided which is easy and positive in its operation and any design-may be repeated simply by identifying the previous positions of the changeable factors and replacing the toggle arms in Atheir previous positions.

-Any desired degree of pressure engage- .ment between the pencil and paper may be provided and by loosenin the screws 58 the pencils may be caused tol ear lightly on the paper. A multiplicity. of similar designs may be traced simultaneously by using two or more pencils thus further providing for a compflication of designs.
