or pattern of various transitions and fittings used in air-conditioning, ventilation, branches of sheet metal work.
An object of this invention is to provide a simple and inexpensive tool or jig of the class described, whereby different pieces of sheet metal necessary to form various transitions and fittings may be laid out without the slow and technical method of pattern drafting utilizingmechanical drawing and triangulation.
A further object of the invention is to provide a device of the character described including a channel body member having a longitudinally extending slot formed through it, and having calibrated semi-circles of different dimensions adjustably connected to said body member and slidable along said slot, said semi-circles being adapted to receive various sizes and shapes of plates, and cooperating positioning pins or points being associated with said semi-circles, whereby various and other metal working transitions and fittings maybe quickly laid out.
A further object of the invention is to provide a metal working jig which is highly efiicient in operation, and relatively inexpensive to manufacture and produce.
Other objects will appear as the description proceeds.

Figure l is a perspective view of the improved metal working jig;
Figure 2 is a longitudinal sectional view taken through the jig;

Like characters of reference are used throughout the following specification and the accompanying drawings to designate corresponding parts.
In carrying out the invention, there is provided a channeled body member I having a flat top 2 and dependin side flanges 3. The body I is formed with a longitudinally,extending slot, '4 which extends to points near its extremities.
The semi-circular calibrated scale bodies 5 and 6 are provided with the degree calibration '5 along t ir rv d edsesae are r id with th a s ate l t 3;. adia entto a pa with; the ?1 d,,ll ld e g s Ad t nsi o 9 n il'fle e tend through the slot 4' and through the said scale bodies 5 and 6 to permit angular shifting of said bodies with respect to the body member I, and to clamp the same in fixed position when the shifting has been accomplished. A centering pin I! extends downwardly from the true center of the scale bodies 5 and 6, the body 5 being somewhat larger than the scale body The flat sides of the scale bodies 5 and 6 are upturned to form the vertical flanges l2 and i3, respectively, and cooperate with the combined clamps 4 and Hi, the same being formed with the detachable points or pins i6 and H, also having the set screws i8 and i9 threaded through their upper extremities to clamp various sizes and shapes of plates 29 and 2| in position next to said flanges.
The attachment shown in Figure 3 comprises an upstanding rounded plat'e'22 and a forwardly extending plate 23 adjustably connected thereto by the screw or bolt 24, and formed with the apertures 25. When it is desired to make a pattern for the truncated cone portion of a funnel or the like, the attachment shown in this figure is secured to the channel member I in place of body 5 by means of bolts passing through the slot 4. The distance between this attachment and the body E5v determines the slop of the elements of the conical portion. When the semi- .circular template 2! andthe attachment are secured in position, the device is placed with the curved edges rubbed with carpenters chalk and i facing the pattern paper and it may then be rolled for scribing the outline of the pattern. Obviously, the cylindrical portion of a funnel would present no. pattern problem.
The attachment illustrated in Figure 5 comprises a slotted arm or beam 26 having a head 21 slidably engaged in the slot of arm 26 and formed with a depending integral threaded stud 28. A pair of spaced links 2% are connected by the pin 30 to slide in the slot in the arm 2'6 and axis of. the cone with respect to the base is dependent upon the distance between the lugs 28. and 33, and the altitude of the cone is dependent upon the distance between the point 58 and the base 2!. Tolay out the pattern for the cone, the edge of the semi-circular base is rubbed with carpenters chalk and placed for rolling contact on the pattern paper. tothe extremities of thesemi-circular edge with The device is thenrolled the point 50 acting as a pivot point. By drawing straight lines between the extremities of the re sulting curved chalk line and the pivot point a pattern for half of the cone will result.
The figures 6, '7 and 8 represent various fittings perspectively for making large diameter pipe to small diameter pipe, for making square pipe to round pipe, and when making an elevation drawing of an off-center transition.
The operation of the device will now be generally described as follows when making a side elevation of the required fitting. The proper plates are clamped to the scale bodies 5 and 0, after which the device is placed on the elevation drawing so that thecenter pins ll coincide with the center line and ends of the fitting required, then the bodies 5 and B are swung until the end pins 16 and I! coincide with the line designating the top and bottom of the fitting (see Figure 8). The center pins H are slightly longer than the pins 16 and [1 to allow the plates 5 and 6 to turn after the said center pins II are located. The wing nuts 34 on the end pins H are then tightened, and the edges which will become the outline of the pattern will be rubbed with carpenters chalk. The device is then rolled across a flat sheet of drafting paper producing a line where the chalked edge has touched the paper. In most cases, this operation produces a half pattern which may be cut and .folded to produce a full pattern.
While the preferred embodiment of the invention has been illustrated and described, it will be understood that it is not intended to limit the scope thereto, as many minor changes in detail of construction may be resorted to without departure from the spirit of the invention.
