ratei-atea cet. a, 1ere.

To all whom it may concern Be it known that I, F REDERIOK A. SVLEVEN-A sou, residing at Detroit, Michigan, and berlng a cltizen `of the United States, have invented v certain new and useful Improvements in Fish-Belly-Punching Devices, of which the following is a full, clear, and eX- act description, such as will enable others skilled in the art to which it appertains to make and to use the same, reference being had to the accompanying drawings, which illustrate the preferred form of the invention, though it is to be Vunderstood that the invention is not limited to the eXact details of construction shown and described, as it is obvious that various modifications thereof will occur to persons skilled in the art.

In said drawings: Figure 1 is a frontelevation lof a machine embodying my inven tion. Fig. 2 is a longitudinal vertical sec- 'tion through the same. Fig. 3 is a bottom lan view of the upper part of said machine. Jig, 4L is a horizontal section along the line of Fig. 1. Fig. 5 is an end view of the machine. Fig. 6 is a vertical transverse section along the line 6 6 of Fig. 1. Fig. 7 is a sectional detail view, showing the control of the punches through the agency of the gag; and, Fig. S shows a digrammatic fish belly sill as it would appear in plan view, 'when in place in the machine, disclosing the positions of the holes to be produced along the broken line edge.

Fish belly center sills, and in some instances side sills of this form for railway car underframes, present the problem of avoiding awkward manipulation of the web plate of a builteup sill, in punching those holes which parallel the sh belly outline. If the end of such a web plate be advanced through a multiple punch, the movement of the plate being in the direction of itslength, it is impossible to set up a gang of punches which will punch each succeeding hole that parallels the fish belly outline as it arrives in sequence at the line of punches which are disposed transversely of the web plate. That is to say, each succeeding hole to be punched adjacent the diagonal edge of the fish belly outline of the web plate is later-v ally offset from the preceding one by an in-,

sufficient space to permit a side by side ar rangement of punches adaptedV to succes holes. Consequently, these holes running beside thefish'belly outline must be produced by another operation, usually involving the removal of the plate to another punching machine, and an ungainly action in presenting the broken line fish belly edge of the web plate to the punch or punches which are to perform the Vwork upon it.

An object of the invention herein set forth is to provide simple and eective means to eliminate more than a single handling of sill web plates of the sh belly type, and a further object is to produce the punching of all the holes in said plate by a single passage through the multiple punch in which this device is installed.

Consulting the drawings, 1 indicates a bottom plate secured'to thevbed of a multiple punch over which web plate, shown in dot and dash lines at A in Figs. 1, 2, 5 and 6, travels intermittently, being halted whenever a punching operation is to take place. A top plate 2 is bolted to the slide 3 of the multiple punch, and is positioned above the bottom plate 1. The latter is provided with a T-shaped slot i in which is located a slidable die block 5 containingy dies 6 and 7. In the cooperating top plate 2 is another T-shaped slot 8 to accommodate a slidable lpunch block 9 which carries punches 10 and 11.

The punch block 9 and the die block 5 are caused to slide in unison in their respective v T-slots transversely of the fish belly sill through the agency of rack 12 attached to -punch block 9 and rack 13 attached to die block. Racks 12 and 13'mesh respectively with pinions 14 and 15, the latter possessing square central holes which fit about a squared vertical shaft 16 and arerotated by it, thereby, of course, actuating punch block 9 and die block 5 through their racks. The rotation of the shaft 16 is produced by turning a hand wheel 17 whichalso has a squared central aperture surrounding said shaft. 'The racks, which are rectangular in cross section, are reduced at one end to form a threaded cylindrical stud. The stud on rack 12 passes through a hole in punch block 9 and is fitted with a. nut-` 18 which clamps the rack to said punch block.

"Similarly rack 13 is provided with a stud fitted with a nut 19 whereby said rack is securely V clamped to the die block. Both work.

punch and die blocks contain a rectangular aperture or pocket 20 to accommodate the nuts for their racks.

rEhe pinions 14 and 15, with which the racks 12 and 13 mesh are seated in recesses 21 in castings 22 and 23, respectively, the

As the pinions propel the racks 12 and 13' in one direction, or the other, upon the rotation of the hand wheel 17, a pointer 2A, secured to gag handle bracket 25, which bracket is fastened to punch block 9 by means of tap bolts, rides over a templet 26 that is screwed to the slide 3. On this templet are graduations marked a, Z), 0, d, etc., by the aid of which the operator can bring the center' of one of the punches over any predetermined point on the fish belly sill A to be punched. ln other words, the longitudinal position of a proposed hole isqdetermined by the amount of advance of the sill through the machin-e and its transverse position by moving the punches transversely until the reading on the templet given by the pointer which, of course, travels with the punches, indicates that the proper lateral location of the hole has been reached. The operator may have a tabulated schedule which will tell him whether any particular hole in given job requires pointer 2el'to be brought to a or or c, etc., to insure that either punch 10 or 11, according to which is to be used, each being of a different diameter, has moved the correct'distance laterally to locate the transverse position of the proposed hole. After the positioning of the punch chosen, the gag 27 must `be inserted over the stem of said punch to fill the otherwise present space, so that there will be no lost motion in the downward thrust of the punch, the absence of which lost motion insures the perforation of the fish belly sill. For example, if punch 11 is to be operated, the gag 27 will be in the-position shown in Figs. 2 and 7, and, while this punch must accompany the slide 3 throughout its entire stroke, the aperture 28 now present above punch 10 will prevent this last mentionedV punch frombeing forced to penetrate the Rotative movement of the gag handle 29 to the left in Fig. 1, (see also Figs. 2, 3, 6 and 7 for a certain distance will remove the gag 27 from over .the punch 11 and dispose it above punch 10, which will then be the one in operative condition leaving punch 11 ineffective. By such movement of gag handle 29, shaft 30, is partially rotated, the handle being keyed to it. lnasmuch as the bifurcated arm 31 is also keyed to shaft 30, it revolves 1n unison with gag handle 29, and the outstanding lug 32 of gag 27, protectively positioned in said T- slot 8, and into the open slot of arm 31, is set into motion thereby, of course, actuating the gag 27. A still further rotation of gag handle 29' to the left would remove the gag from over punch 10 and both punches 10 and 11 would consequently be inoperative. rEhe bottom plate 1 is provided with apertures 33 through which slugs punched from the sill or other work may find escape to a scrap pile.

The operation of the machine above described isras follows: The work, say a fish belly center sill web A, is inserted into the machine, end first, the direction of its feed being perpendicular to said end, that is, the same asv the direction of the length of the sill. rIyhe sill is advanced until the longitudinal position of the first hole to be punched is directly under the centers of the punches. After consulting .a tabulated schedule, by means of which the size of the punch needed is disclosed and also the letter, or symbol, which indicates to what graduation on thjevtem'plet 26 the pointer 2A isl to be moved in order to bring the desired punch in agreement with the lateral position of the proposed hole, the operator revolves hand wheel 17 until the' pointer 24 has been brought to correct stopping place over the templet 26. Turning hand Wheel 17 imparts rotary motion to the pinions 1li and 15 through the. vertical squared shaft 16, and these pinions impel the racks 12 and 13 in one direction or the other, according to the direction of rotation of hand wheel 17. With the racks travel punch block 9 and die block 5, thereby moving the punches 10 and 11 and the dies 6 and 7 across the face of the web plate to be operated upon, until the pointer 24 stops at the proper graduation on the templet 26. Gag handle 29 is then rotated, and with it the gag handle shaft 30, and the bifurcated arm 31, the latter, by reason of its connection with the outstanding gag lug 32 bringing the gag 27 over punch 10 or 11, as directed from the tabulated schedule, to renderv it operative. By means not shown, but well known, the slide 3V is caused to descend, and, if punch 11, for instance, is gagged it will perforate the fish belly sill web A, while punch 10, upon reaching-said sill will recede into the aperture 23 in the gag 27, and perform no work. Tere the gag- 27 withdrawn from over punch 11 by the requisite movement of gag handle 29 to the left in Fig. 1, to a point where it resided above punch 10, this punch would become operative and punch 11 ineffective. VStep by step the fish belly sill web A is advanced, and the selection of punches and the lateral positioning of them, continues, as above described, until all the holes longitudinally disposed along the fish belly edge B of the sill web have been punched. The punches shown at 34E and the dies at 35 belong to a gang of punches permanently set up for a. particular job and are used to punch all proposed holes in the fish belly sill web that shall be in alinement with them.

Vhile this machine has been described as being adapted to punch holes paralleling the fish belly outline of a center sill of this type, it is to understood that the machine is not limited alone to this specific task and may be employed in general for producing holes in whatever materials are susceptible to punching` operations wherein the contour is irregular and holes are to be produced paralleling such contour. Furthermore, oppositely disposed machines of the type described may be set up in a multiple punching machine -and more than one irregular line of holes be produced at the same time.
