TTORNEY STATES AUGUST THOMSEN, OEGLENDALE, NEW YORK.

MACHINE FOR MAKING METAL SPO'UTS AND TUBES.

Application filed July 16,

T aZZ whom it may concern:

Be it known that I, Aoeus'r THoMsnN, a citizen of the United States, and a resident of the borough of Queens, Glendale, Long island, in the county of Queens andState of New York, (whose post-office address is 233 1- Edison Place, Glendale, Long Island) have invented new and useful Improvements in Machines for Making Metal Spouts and Tubes, of which the following is a full, clear, and exact description.

The present invention relates particularly to machinery for manufacturing the end pieces or shapers for spouts. These spouts may have various uses. One particular use is in conjunction with a decorating gun for confectioners use, by which ornamentation is placed upon cakes or similar articles. Other spouts, such as required for oil cans and similar devices, are also formed by this machine. I

Among the principal objects which the present invention has in View are: To impart more perfect shape than heretofore to the spoutforming members; to simplify the construction of the spout; to diminish the time required for the construction; to increase the scope of usefulness in machines of the character mentioned; and to permit rapid and simple alteration in the shapes of the spouts formed thereby.

Description.

As seen in the drawings, and particularly by reference to Figures 10 and 9 thereof, the blank A shown in the former figure is curled about a shaping mandrel to be manually stripped therefrom as the spout B disclosed in the latter of the said figures. The shaping or curling of the blank to the shape shown in Figure 9 is primarily accomplished by the smoothing blades 16 which are adjustably secured by set screws 17 on sliding plates 18. As shown best in Figure 4 of the drawings, there are two plates 18, which plates are guided in slots provided in the swinging frames 19. There are two frames 19, each being independently pivotally mounted on the shank 20 of the mandrel 15' and on the end of a lay mandrel 21. The

mandrels

15 and 21 are held stationarily in heads 22 at the upper ends of standards 23. The standards 23 are made secureto the base plate 24.

The plates 18 are further guided by the braces 25 and by the shank of a bolt 26 which extends through the said braces and through perpendicular slots provided in said plates. These bolts 26 assist in preventing the plates 18 shifting lengthwise of the frames 19.

The plates 18 are reciprocated to and from the mandrel 15 by means of levers 27, of which there are two, each being furnished with a handle 28. The levers 27 are of the character generally termed bell-crank levers, and the short arm 29 thereof is attached by means of a pivot screw 30 to one of the plates 18. To permit the movement of the screw 30 through outer brace 25 a curved slot 81 is provided in the said brace.

The smoothing blades 16 are adjustable fastening bolts 37 extend.

hollow angles being turned on the plates 18, each of the smoothing blades being provided with an elongated slot 32 through which the shanks of the screws 17 extend. V

s seen best in Figure 4-Of the drawings,

the screw 17 extends beyond the plate 18 toform in conjunction with the braces a stop for determining the retracted position of the plates 18. This position is shown best in Figure 2 of the drawings, where the head of the screw 17 is disclosedas bottomed in a recess 33 in the brace 25.

The blanks shown in Figure 10 of the drawings are disposed under the mandrel 15 and above the blades 16, the blades 16 being retracted to leave a clearway below the said mandrel, seen best in Figure 2 of the drawings. l I

The position of the flat metalis regulated by: the gages 3 1. The gages 3a are movably attached to extended brackets The brackets are each provided with a lengthwise slot 86. through which the shank of These bolts are employed for determining the position of the gages 3 L.

As seen. best in Figure 1 of the drawings, the gages 3 1- are rectangular in shape, the toward each other to receive the lateral corners of the blank shown in Figure 1.0. r

lVith the mechanism constructed and arranged as above disclosed, the operation of curling the blank shown in Figure 10 to form the spout shown in Figure 9 is as follows: Thev blanks are successively fed to the mechanism by placing the blanks within the gages 3 1, to; rest on the support 38 in the said gages. The operator then grasps the handles 28- and moves them from the position-shown in Figures 1 and 2 of the drawings to the. position shown in Figure 3. This closes the blades 16 on the blank to hold the same between the said blades and the said mandrel at opposite sides of the said mandrel. The handles are then swung from the position shown in Figure 4: to the position shown in Figure 5. The levers 27, of which the handles 28 form a part, and the parts associated therewith including the blades 16, are swung around the axes of the

mandrels

15 and 21,. with the result that the metal blank shown in Figure 10 is curled to the form shown in Figure 9, closely hugping the mandrel15. In the final operation,

the lapped seam shown in Figure 9 is accomplished by rocking both levers and parts associatedtherewith around the mandrel 15 and partially formed spout thereon in the direction in which the outer layer of: the seam. is folded. V

Having thus shaped the blank into the spout, the. handles 28 and parts associated therewith are returned to the original position disclosed in Figures 1 and 2 of the drawings, when a succeeding blank is placed within the gages 34: and the operation repeated.

It is obvious that the operation performed by means of this mechanism is very rapid.

The spouts formed by the present machine vary in length and diameter, as shown by a contrast of the spout C indicated in Figures 7 and 8 with the spout B shown in Figures 3 and 9. When making the spout C it is obvious that room must be provided in line with the mandrel 15 and in front thereof for the removal of the said spout. This is accomplished by providing the lay mandrel 39, which is slidably held in the head 22. To secure the mandrel 39 in the head 22 the said head has an extended flange 40 wherein bayonet slots a1 are provided to engage pins 12. extended from the mandrel;39. To facilitate the operation of the mandrel 39, handle bars as are provided whereby the said mandrel may be quickly adjusted to service position. To assist the elongated mandrel 15 and to steady the same during the operation, the mandrel 39. has a centering pin n the end of which enters a shallow socket in the said mandrel15 or within the pocket formed by the contracted end of the spout G. In either event,

the free end of the .mandrel 15and spout being formed thereon are supported and steadied during the operation of curling the blank.

While the mechanism-has been shown and described as forming tapered spouts, it will be understood that when desired cylindrical tubes may also be constructed by the mecha- Claims.
