DEVICE FOR MAKING DESIGNS.

Specification of Letters Patent.

Patented Sept. 2, 1913.

Application filed October 8 1912. Serial No. 724,547.

To all whom, 2'1 may concernv Be it known that I, LYNN L. ALLEN, a citizen of the United States, and a resident of Atlanta, in the county of Fulton and State of Georgia, have invented a new and Improved Device for Making Designs, of which the following. is a full, clear, and exact description.

My invention has for its object to provide a device for making designs, having a bar 'arrying a marking member, the bar being operated by a rotatable member to which it is articulated, the marking member being adapted to produce a design on a table which is reciprocated as it. is rotated, and while the bar with the marking. member is operated.

Another object of the invention is to provide convenient means for securing the markingmember to the bar and to assist in adjusting the marking member in the dc sired position.

Other objects of the invention will appear in the following complete specification, in which the preferred form of my invention is disclosed.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of ref crence indicate corresponding parts in all the views.

Figure 1 is a plan view of my invention; Fig. 2 is a front ele atio-n of my invention; Fig. 3 is an end view of my invention, showing the means for rotating the screw member; Fig. at is asectional View on the line i-l of Fig. 1; Fig. 5 is an enlarged fragmentary sectional view of-the table, showing the guideway in which the reciprocating member travels; Fig. (3 is an enlarged side elevation of the bar, showing the means for carrying the marking members; and Fig. 7 is a plan view of the structure shown in Fig. 6.

In my device the table is reciprocated as well as rotated, while the bar with the mark-' ing member is operated, the belt being so disposed that the belt will rotate the table while the table is being reciprocated. The bar of the device which is provided for carrying the marking member has openings through which extend the central portions .of spring members provided for embracing the marking members for holding the marking members in position.

It will be seen by referring to the d 'awings that a board 5 is provided, having a slot 01' guideway (3 in which the member 7 is adapted to reciprocate. In the board 5 there is a longitudinal opening 8 which serves as a bearing for the screw member 9, this screw member 9 extending into the slot or guldeway (3, and being prevented from mov ng longitudinally of the board 5 by a pulley 10, which is secured to the screw member 2) at one edge of the board 5, and

by the locking nuts 11 which engage the screw member 9 and press against the board 5 at the end 12 of the slot .or guideway 6. This screw member 9 also extends through an opening 13 in the member 7, the screw member 9 meshing with the thread on a nut' 14 which is disposed in a recess 15 in the member 7. The nut 14L is held in this recess 15 and is prevented from rotating relatively to the reciprocating member 7 by the engagement with the member 7 at the point 16. \Vith this construction it will be seen that when the screw member 9 is rotated, it will move the nut 1Z1. relatively to the board 5, which will carry with it the member 7.

livoted to the member 7 there is a tablo 17 to the upper face of which a member 18 may be secured by the pins 1!), so that the design 20 may be drawn on the sheet 18 by the marking member 21. Not only is the table 17 pivoted to the member 7, but there is a pulley 22 pivoted to this member. Additional pulleys 23, 24, and 26 are pivoted to the board There are also rotatable members 27 and 38 which are pivoted to the board 5, the rotatable members 27 and 38 being connected by a link 2!), one end 30 of which is articulated to the rotatable member 2.7, and the other end 31 of which is articulated to the rotatable member This end 31 of the link 29 may be articulated at any one of the orifices 32, to alter the movement of the rotatable member 28 by the link 29 which operates it. A belt 3?, is disposed around the table 17 and the pulleys 21 23, 24, 25 and 26, and also around the rotatable member 27. It will therefore be seen that when the pulley is rotated by means of the handle 34, it will rotate the rotatable member 27 and also the table 17. 35 is articulated at the end Zltitc the rotatable member .28, and this bar 37). which carries the marking members 21, is disposed across the top of the table 17 and the sheet 18, so that the marking members .21 may en- The bar gage the member 18. The bar has a slot 36 in which is disposed a pin 37 secured to a clamp 38, this clamp 38 being ad ustable along the edge 39 of the board 5, and being held in any desired position by means of the set screw 40. It will therefore be seen that with the rotation of the rotatable member 27, the rotatable member 28 will operate the bar to draw the design by means of the marking members 21 on the sheet 18, and while the table 17 carrying. the sheet 18 is rotated. In addition to this rotary movement of the table while the design is marked thereon by the marking members 21 carried by the bar 35, the table 17 has another movement, as the member 7, to which it is pivoted, is moved longitudinally of the board 5 by means of the screw 9, this screw 9 being rotated by the pulley 10 which 1s secured thereto, and which is connected with the pulley 41 by the belt 42, this belt 42 passing around the pulleys 43 and 44 in the manner shown in Fig. 3 of the drawings. The pulley 41 is secured to the pulley 23 to rotate therewith. Itwill therefore be seen that when the pulley 25 is rotated by the handle 34 it will rotate the table 17, and it will atthe same time rotatethe rotatable member 27 which, by means of the link 29, and the rotatable member 28, will operate the end 26 of the bar 35 which carries the marking members. It will also be seen that as the pulley 23 rotates, it will rotate the pulley 41 secured thereto, which, by means of the belt 42 will rotate the pulley 10 to which is secured the screw member 9 which will rotate with the last-mentioned pulley. The rotation of this screw member 9 will move the member '7 in the slot or guideway 6 by means of the nut 14. As the member 7 moves in the slot or guideway 6 to the position shown by the dotted line 45 in Fig. 1 of the draw ings, the pulley 22 will move with the member7 tothe position shown bythe dotted line l-(i in the said figure of the drawings. This movement of the pulley 22 acts a belt tightcner, permitting thebelt to move, and thereby permit the movement of the table 17. hen the table 17 is moved with the member 7 in the opposite direction, the pulley 22 will also move in the said opposite direction, taking up the slack of the belt 33. As will be seen in Fig. 6 of the drawings, I prefer to provide the bar with a member 47 having openings 48 extending horizontally theretln-ough, the spring members 49 extending through these openings 48, the spring members 49 having ends 50 secured at one side of the member 7, the spring members then extending through the openings 48 in the member 7, and being provided with terminals 51 which are disposed at the side of the member 47 to which the ends 50 are secured. These spring members 49 normally embrace the marking members 21, as

best shown in Fig. 7 of the drawings, to hold the marking members in position. In adjusting these marking members 21 in osition, I make use of an eccentric mem er 52, which is pivoted at 53 to the bar 35, the eccentric member 52 being normally disposed upward, as shown by the full lines in" Fig. 6 of the drawings, so that it will not interfere with the movement of the bar, but when desired this eccentric member 52 may be moved down to the position shown by the dotted lines 54 in Fig. (5, so that it will support the bar 35 while the marking members 21 are pushed down to the desired position.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:
