TEMPLE'I HOL DING AND DIRECTING MACHINE.

To all whom it may concern:

Be it known that I, CHARLES H. NICHOLS,

a citizen of the United States, residing at Haverhill, in the pounty of Essex and State of. Massachusetts, have invented an Improvement in Templet Holding and Directing Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters on -the drawings representing like parts.

- pattern makers, and draft'smen, and has for ruler, is so mounted that said holder may be moved in all directions and yet will'niainits object the provision of means for holdinga pattern (for instance a shoe pattern), a rafting instrument (for instancea ruler,

T-square, or triangle), or any other directing' tool or device from which a copy is to be made or which is to be used in'making a plan 'or a drawing. i

In carrying out my invention, I provide a holder in which the tool, for instance, a

tain said ruler at all times in arallelism to itself, b which I ,mean that t 1e ruler when moved rom one position'to any other position willremain parallel to itsoriginal position, unless purposely changed in directionQ Besides this leading feature of my' invention,:

it includes means for preventing the tool or ruler from dragging on the board, andmeans for maintaining the ruler unyaryinglyv in whatever direction it is placed 1rrespective of whatever iosition. it may oc- P)", S0 t he tool may be used'on a plurality of boards for making duplicate drawings, or, for eirample,"for making-an assem bled drawing on-one board and details on another board and yet preserve the identity:

of every corresponding angle and line on all the boards; Also I provide two" rotraetors so arranged as to secure theresu ts of a T- square .or triangle by the useof astraight.

As herein shown, I have mounted my instrument on a work table or drawing board 1 by means of a bracket 2 and screw clamp -3' whosehead 4 engagesthe' under side of the table, being operated by a hand wheel 5.

In the outer end of the bracket is rigidly secured, asby means of a threaded end 6 and nut 7 a stationary shaft 8; on which an arm 9 is mounted to turn freely. At its outer or free end said arm isprovided with relatively long vertical bearings in which rs mounted a vertical shaft 10; "On this' shaft 10 are mountedtwo parallel rods or lmks 11, 12, which are secured at their outer ends to a vertical shaft 13 in the same manner that they are secured at 'their.'innerends, see Fig. '11. Viewing Fig. "11, it will be seen that a bearingl l is mountedt'o turn 7 on theshaft'lO (o-r l8, as the case may be)v and is pivotally'connected atits-ends by a yoke 15 to therod 1'1 (or-12, as the case may Thus the shaft 13, while always free 'tobernoved up or down with relation to the shaft '10, is maintained in absolute parallel ism therewith. A'lso both of said shafts are free to turn axially at all times. Provislon ismade' for compelling said shafts to maintain at all times the same relative'axial position, the means herein shown for this putpose comprising -a wheel or pulley 16 mounted on the shaft IO 'and an identical wheel or pulley 17 mounted'on the shaft 13,-

sal tilt-ing movement in accordance with the dere changing positions of the rods or links. 11, 12, as shown in Fig. 4, where it will be seen that the wheel 16 is connected by a gimbal or universal joint with a central bearin move in unison by any suitable means as by a belt 22 of piano-wire wrapped a-plurality of times around each pulley and pinned or fastened thereto.

At its upper end the shaft 10 has fast; thereon a pulley 23 connected to a pulley 24 p on the upper end of the shaft 8, said two pulleys being connected to ,move in unison by means of a belt 25 of piano wire or nonyielding material the same'as just described for the other pulleys. The pulley 24 is pref erably capable of ad'ustment on the shaft8, being provided for t is purpose with a split collar 26 and a clampingthumb-screw 27. Its peripheral top edge is graduated to .provide a protractor scale 28, Fig. 2, and a protractor arm or sectorj29 is mounted on'the post 8 to coiiperate therewith, being held clamped in desired adjust mmtgby means ofa thumb-screw 30. I 7 At the lower end of the shaft 13isse'cured a shouldered part 31 of aprotractor, herein shown as having a zero mark. 32 to registerwith a graduated scale on an annular mem ber 33 which is mounted to move inthe ad'- Q jacent shouldered flange of .the part 31. and

is threaded at 34 to the peripheral portion of a block 35. This block has a central part 36 which serves to center it and afford piv otal movement relatively to part '31 and shaft 13, and'at one'side it is provided with; a dog 37 pivoted at 38 and normally held in;- locking position by a spring 39. This dogrovided in the shoulenga es notches 40 periphery of t e'part 31. At t sisting, as herein shown, of a sleeve-like the like 41, and the foot or laterally extended base of the part 42. The latter is normally held downward by a spring 47 f bearing at its upper end against a shoulder 18 fastened by a pin 19to the vertical shaft, said universal joint having its pivots 20, 21' disposed at right angles to each other in well-known manner in this kind of a-joint. The two pulleys 16 and 17 are connected to 42, Fig, 5.

provided for locking j or braking the movagainst to normally against ah inwardly extending flange 49 of themembe r 42, being retained permanently in position by-a flange 50 of said block member 35. The flanges 49 and 50 on the'members 42 and 35 respectively are arranged to interlock to prevent accidental displacement of the member 42. These parts may be ini;

tially assembled'by having portions of each i i of the flanges 49, 50 cut away so that they may he slipped past each other and ,then turned partially around so as toginterlock as. is usual in bayonet joint connections.

The upper-end of the stem 44-is'iprovided' with a slot 51 to straddle a handcontrolled pin 52, the .lower end of said slot;having an enlargement or socket 53 to be engaged by the beveled inner end of a plunger54held yieldingly by the spring. 39' in position to -'engage' and lock said stem 44 when shoved -upwardl -means 0 holding the tool. In Fig. 6 I- have I .do not limit myself to'this shown a ruler- 55 as provided with a dovetail block 56 for enterin the foot member I desired, and to this'end, as showninFig. 12,

a brake '57 may beprovided, this being shown as ivoted at 58 to the'bracket which supports t 1e shaft Band-having an operat ing arm 59 extending outward from the pivot with a spring '69 operating thereurge the brake shoe against the shaft 13. Thus,when it is dc-1 sired to move'and adjust the ruler, a pressure upon the arm '59 will move the brake shoe away from the'shaft, compressin sprin 6O soithat the parts may be reely move while upon-release of the arm '59, the sprin 60 will urge the brake shoe against said shaft to lock the same from rotation and hold the parts rigid in the posi a tion to'which they are adjusted. It will also be understood that I am notrestricted to the recise constructional details herein shown in the preferred embodiment of ,my, invention, inasmuch as manyvariations in details of construction, arrangement and,

f combination, may be resorted to without dee lower end of the block 35 is afoot piece for holding" a ru'lerlor pattern 41, conparting from the spirit and scope of my invention.

In use, the machine is fastened to a table or thelike as shown in Fig. 1 and then the operator secures the pattern, ruler or other instrument to-the foot of the tool holder as shown for instance in Figs- 1 and 7. The thumb-screw 2 7 of the protractor 28 is then loosened and theruleris turned accurately by the operator to coincide with the base line of the drawing or piece of work that is to be done, whereupon the thumb-screw 2 is tightened. The thumb-screw 30 is then loosened and the sector 29 is swung so as to It is desira le that means, he

the-

bring its zero line to the zero point of the protractor 28, whereupon its thumb-screw 30 is again tightened. The arm portion of the machine is now swung so aS to bring the ruler into proper relation to the paper which is fastened to the board and onwhich the drawing is to be made, and a base line is drawn with reference to the ruler, said ruler being necessarily in parallelism with its former position before swinging of the arm, because it is positively so held by means of the belts 22, 25 and pulleys and shafts from the protractor 24. It may be shifted fro-m the base line to any extent desired, as for shading or making other lines parallel to the base line, without any danger of getting it out of parallelism with the base line. If now it is desired to draw a line at any desired angle from the base line or from any of these other lines, said angle is laid off by means either of the protractor 24 or the protractor 33, preferably the latter. In this manner the apparatus serves the same purpose as the ordinary T-square and triangle,

without requiring the operator to maintain the usual plurality of separate movable parts in proper engagement and relation to each other and also without the danger commonly due to the slipping of said plurality of parts as ordinarily used by a draftsman. But by having several sheets of paper secured to the table in convenient relative position, the operator may carry along the making of several similar drawings at the same time, simply swinging the drawing tool from one sheet to another for the successive lines, without any danger of chang ing the relative angle or getting the wrong measurements, etc. This is particularly useful in making detailed drawings from an assembled drawing or vice versa. There is no inconvenience in handling the tool and there is no tendency to drag the same over the paper as in the case of a triangle, ruler or other ordinary flat drafting instrument when lying upon the paper. By having two protractors, a given variation may at any time be provided with accuracy with relation to any position into which the ruler or tool has been previously turned. For instance, if the ruler has already been turned ninety degrees from the base line by means of the protractor 33, and it is desired to turn it two degrees still farther without disturbing the measurement indication of the protractor 33, this is done simply by turning the protractor 24 said two degrees with relation to the indicator arm 29. Whenever a different tool is required, the

operator simply pushes inwardly upon the pin 52, thereby disengaging the locking plunger 54 from the stem 44, thereby permitting the latter to be lowered to release the tool and receive another. The stem with its new tool or instrument in place is then shoved upwardly so as to bring the tool hard against the member 42, the upward movement being continued until the same is again locked immovably in place on the block 35.
