SHEET-METAL-BOLLING MACHINE FOR TENDERS THE LIKE.

Application filed September 3, 1921. Serial 1T0. 488,854.

To all whom it may concern: v y Be it known that I, HOMER R. KENNEDY, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles 5 and State of California, have invented new and useful Improvements in Sheet-Metal- Rolling Machines for Fenders and the like, of which the following is a specification.

This invention relates to sheet metal tools, and particularly to a sheet metal tool adapted to crown or form fenders orother sheet metal objects.

The invention has for an object the provision of a device which will form sheet metal into various shapes with a minimum of time and labor expended, and which will perform its work in a superior manner.

This invention is an improvement upon and a departure from the invention of Robert W. Carter fior improvements in sheet metal working machines for fenders and the like,

U. S. Letters Patent No. 1,244,422, issuedv October 23, 1917.

In practicin the invention I provide a sheet metal ro ing machine which incorporates in its simplest embodiment a template member or a forming member and a member co-operating therewith. The template member carries the sheet metal to be formed, while the second member rolls over the sheet metal and the template and presses or forms the sheet metal into the desired shape. It is customary to hand-peen or to strike out at one blow automobile fenders. When metal is treated in this manner, however, it is subjected to great stress at certain parts thereof, which weakens the entire structure. In accordance with my invention, the metal is stretched gradually and formed without 4 weakening it, such as would occur when the metal is stamped. When metal is stamped it is impossible for it to follow, due to the quickness of the st amping operation. My device does not crystallize, abrade, or harden the metal, as is the case with hand-peenin'g or hammering. A device of this character performs a. neat'job upon the metal to be formed and the finished product does not reuire bufl'mg or finishing of any kind, but t e sheet metal is immediately ready for enameling.

The invention has for further objects the provision of an improved sheet metal machine of the character described which will used in practicing the invention;

be superior in point of relative simplicity and inexpensiveness, taken in conjunction with utility, durability and general efiiciency and serviceability. With the above mentioned and other obects 1n view, the invention consists in the noveland useful provision, formation, construction, combination, association and interrelation of parts, members and features, as illustrated in some of its embodiments in the accompanying drawings, described in the following detailed statement, .andfinally pointed out in claims.

In the drawings: v Figure 1 is an elevation of my improved sheet metal working machine; Figure 2 is a fragmentary front elevation of the machine shown in Figure 1, taken on the line :v w Figure 1, and looking in the direction of the appended arrows;

F1gure 3 1s a fragmentary cross sectional v ew takenon theline v -m Figure 2, and

looking. in the direction of the appended arrows;

Figure 4 is a plan view of weight members used in practicing the invention, said view being taken on the line ea -m, Figure 3, and looking in the direction of the appended arrows;

Figure 5 1s a detail of certain elements Figure 6 is a fragmentary elevation showing a base member in conjunction with a roller member used in practicing the invention; 1

Figure 7 is a fragmentary to plan'view of certain forming members use in practicing the invention;

Figure 8 is a cross sectional view taken on the line afi-afi, Figure 7 looking in the direction of the appended arrows;

Figures 9,10, 11 and 12 illustrate sheet metal objects after being formed into various shapes by the device.

Corresponding parts in all the figures are designated by the same reference characters.

Referring with particularityto the drawings, I have designated the sheet metal working machine in its entirety as A, of which a is a structure, b a fulcrumed lever arm, 0 an oscillating or working arm, at a roller member, 6 a mold or template, and f a base or seat member,--all of which elements are used in practicing one embodiment of my invention. The elements shown from a to d inclusive, are more or' less standardized, 'while the elements e and 7 may assume a variety of shapes and forms as will more fully appear in the body of the specification.

The structure a may be the beam of a .buildingormay be a separate piece joined to some structure, so that the same may be.

supported above the template-or mold e and the base 7 in order that the roller (i may operate upon the template 6 andmaterial carried by the template. The structure has pendent therefrom two cheek or fulcrum plate members 1, the said cheeks,

being held on .opposite sides of the structure a, as by means of bolts 2. As stated, the structure a may be joined with afurther structure as 3. The lever arm is fulcrumed at any one of several points between the cheektmembers 1, as shown at 4. Said lever arm is further confined between two brackets '5 to prevent the lever arm from having lateral play. Joined to said lever arm as at 6 is the oscillating arm 0. To hold the arm a I provide U-bolts 7 straddling opposite faces of said lever arxn-and held by means of U-bolts 7. Normally confined within the.

curved seats at- 10 andll is a ball 13 which ball has a, screw threaded stem 14 joined therewith and passing through the opening 12. A hexagonal-reducing coupling 15 with a lock nut .16 receives the stem 14. Said member 15 is screw-threaded as at 17 for reception of a member 18,.which is annular in formation for a certain distance to where it forms anannular flange 19. The remaining portion'as shown at 20 of said member 18 is slotted as shown at 21. A shank 22 is provided at one end'with a yoke 23, and

'. at the other end with a quadrant member 24. The shank 22 and the quadrant member '24 are adapted. to be received. within the slot 21. Both the portion 20 of the member 18, and the shank 22 are-perforated for reception of a bolt 25. Thus the shank 22 may be oscillated back and forth within the slot 21. Said quadrant member 24. is provided with a curvedslot 26. The portion 20 ofv the member 18 is provided with an enlarged transverse opening 27 and a smaller transverse opening. 28. A bolt member 29 is adapted to be passed through said openings 27 and 28 and the opening 27 is large enough to receive the head, as

.30, of said bolt; passes through the curved slot 26 of the Said bolt 29 likewise quadrant member 24. The bo1t'29 carries a tail nut 31. Thus by turning the tail nut upon the threads of the bolt 29 the head 30 of said bolt will be drawn against the shank 22 locking the shank in any one of a plurality of positions, one of which positions is illustrated by dotted lines 32 in Figure 2. The yoke 23 is provided with tWo-journaled portions 33 which are adapttogether by screws or t e like 35, so that the roller. d may be chan ed and other Eollers of various shapes su stituted there- A hinged arm or compensating arm 9 is joined with the lever arm 6. A portion of said arm 9 is fixed to the lever arm, as indicated at 36, while'the remaining portion, as 37, is hinged to the portion 36, as shown at 38. The free end of the portion 37 is formed with an eye 39 and tackle means It is joined with said eye member. Said tackle means includes a tackle block is provided with a differential clutch and with the usual operating rope m. Thus by pullingon the operating rope m it is possible to lift the lever arm I) in any one of several positions.

Beneath the arm I; is a spring 1:. which is adapted to contact with the portion 37 of the means g and to keep said portion 9 normally away from the arm I). The tackle block in is held to the structure a by means of an arm 40. The operating rope m after passing through the tackle block may extend over to where it is carried by a rope hook 41 on the members 5. The tackle block likewise has a clutch release 42 so that'afterthe operating rope has been pulled so as to adjust the lever arm for a certain height the lever arm will not slip until the differmember 18 and said member 46 is provided "with two arms 47 carrying win-g bolts 48 passing through said arms 47 and adapted to contact with a surface of the weight blocks 43. Said member 46 is split at a portion thereof as at 49 and provided with two outstanding spaced lugs. A bolt 50 passes through threaded perforations in said lugs so that by turning .the bolt member 50 it is possible'to securely. clamp the member 46 to the member 18. The elements just described are standard for allfunctions to be performed by this machine. The remaining devices to be described mayvary in accordance with the work to be performed.

Referring to Figure 1 I have shown a base member 7 having a curved seat51 upon which seat the plate or template (3 may be received.

Referring to Figure 1, the template sides a are adjusted to a pre-determined width and 'a head 57 is connected therewith and the metal to be worked or formed into a given shape is then looked upon said template (2 by means of the clamps 64. \Ve will assume that the sheet metal to be worked is that indicated at 62 in Figure 2. The template 6 is placed upon the base f, and the differential clutch is released through the medium of the arm 42 and by grasping the operating rope the lever arm I) is slowly lowered so that the roller member (2 may come in contact with the sheet metal 62. After this is done and the necessary weights 43 have been placed upon the oscillating arm 0 an operator grasps the handle members 69 and 69 of the quadrant member 24 and imparts universal oscilla-' tion to the roller 03 so as to pass the same uniformly over the sheet metal 62 and form it to the template 6, producing, in the instance under discussion, an automobile fender. It is to be particularly noted that as the arm 0 is oscillated the arm I) oscillates up and down freely, inasmuch as the arm 9 is at all times kept away from the arm I).

through the medium of the spring'n. This P pairs of perforations 70 in the guide arms 5.

In Figure 6 I have shown a template base p having a fiat upper surface 71. A piece of metal can be slightly crowned by placing the same on the fiat surface of the base and moving the roller member (Z. over the same. It is best toplace some form of flexible or yieldable'board over the upper sur-- face 71, rather than place the metal to be formed on the surface 71, as the board may be com ressed giving aid in crowning the materia In Figures 7- and 8 I have shown a further form of a template or forming -member designated in its entirety as g, which template includes a ring member 72 provided with inwardly directedlugs 73 which are formed with transverse perforations,

the ring member by means of a tail nut 77.

To accomplish this clam-ping I slot a portion of the ring member 72 as shown at .78 and a. pivoted bolt 79 is carried by the ring member and adapted to be received within the slot 78. The bowl 76 is likewise slotted as at 80 and the bolt 79 when swung upon its pivot will pam within the slot 78 and the slot 80, whereupon by turning the tail nut 77 said nut will bear against the top surface of the bowl 76. The bowls are made in various shapes and forms and of varying depths. As before stated, the metal to be worked is placed within a curved or depressed portion 81 of the bowl 76 and the roller d brought to bear upon. said metal, as 82, so as to form it to the desired shape. These bowl members 76 are particularly adapted to form fully crowned fenders or the ends of gas tanks, etc. Obviously bowls of varying depths may be provided soas to form various crowning depths in the metal.

Figures 10 and 11 show completed fenders formed by a bowl such as that illustrated at 76. The fender shown in Figure 11 is formed@ by the template e, while the fender illustrated in Figure 12 is formed by the template 6 acting in conjunction with the base p after the fender has received a sufficient crown. It is thus seen that very complicated shapes of metal objects may be readily formed, such metal objects having a deep crown at one point, a straight portion,

a reverse curve at another portion, and then a further crown. All of this is easy of accomplishment with this machine.

The ball 13 allows the arm 0 to have a universal swing. Bracket members 86 and 87 may be joined to the cheeks 1 and with the supporting structures 3 so as to securely brace the cheeks 1. Perforations 88 in the checks 1 allow for adjustment of the lever arm 6.

The member 9 is provided with an oil cup 9 for lubricating the bearing so that the Y ball member may move easily. Attention is also drawn to the fact that themember I 14 carries a stop pin 14 so as to limit its movement. 7

It is obvious that many changes'and variations and modifications may be made in departure from the particular description and. showing of the accompanying drawings, in adapting the invention to varying conditions of use and service, without departing from the true spirit of the invention.
