METAL-SHAPING MACHINE.

To all whom it may concern:

Be it known that I, CLARENCE H. RIEGEL, of Niles, in the county of Trumbull and State of Ohio, have invented certain new 'body portions thereof rand a further object is to provide a machine of this character which will form corrugations of the type stated extending longitudinally of the sheet.

The invention will be hereinafter fully set forth and particularly pointed out in the claims. In the accompanying drawings, Figure 1 is a front elevation. Fig. 2 is a plan view. Fig. 3 is an enlarged transverse sectional view. Fig. 4. is a dlagrammatic view showing the positions of the dies or mandrels before being moved to shape the metal. Fig. 5 shows the same parts wit the mandrels foreed together. Fig. 6 is fragmentary view of the completed article. Fig. 7

shows a fragmentary. portion of one set of mandrels. Fig. 8 1s a view of one of the connecting links.

Referring to the drawings, 1 designates a table which is mountedfon the main frame 2 to which it is adjustably held by clamps and bolts 3 which permit the table to be adjusted transversely of the frame, such latter adjustment being controlled by set screws 4. The table 1 is shown as having a portion of its surface cut out, as at 5, to form a chamber or co" to be closed by a top or cover 6 which is pivoted to the table at 7. This top is preferably connected by means of a rope 8 to a counterweight (not shown). When the topis lowered it extends over the chambered portion of the table and is held to the forward thickened portion thereof by locking lugs 9 which are provided with suitable handles by which they may be readily turned on their pivots.

10 designates what I term a pusher. It is Specification of Letters Patent. Application filed November 29, 1911. Serial 1V0. 662,966.

partment which is designed Patented Nov. 19, 1912'.

designed to extend into the chambered portion of the table, tachably secured to a slide 12 which is movable on and transversely of frame 2. The

slide is supported byframe 2 and is movable on the plane of the table, its pusher 10 7 being always in horizontal alinement with the chambered portion of the latter. The

means for moving the slide may be widely varied, and that shown will be readily understood without a detailed description beyond stating that a driven shaft 13 carries eccentrics which impart reciprocatory -mo tions to links 14 which are connected to the slide, the driven shaft deriving its power through suitable gearing from a main driving shaft 15.

On the table Ifplace two separate series of dies onmandrels 16 and 17. All of the mandrels 'are of similar formation in cross section, but those of one series are reversed with respect to those of the other series.

and at its rear it is de- The mandrels of the two series alternate and all are extended longitudinally ofthe bed, their lengths slightly exceeding that of the bed. The mandrels of each seriesare connected only at their outer ends ,lthe'connections permitting them to erally. In Fig. 7 'I have shown-each alternate mandrel as having a head block 20 with openings to accommodate a connecting cross rod 21, and Ihave also eral mandrels of the series 17 connected by a link 22 having oblong slots to accommodate the shanks of the mandrels. The same construction is observed at the other ends of the mandrels of the series 16. Each man-' drel is shown as having, in cross section, a nearly spherical body-portion 23 from which extends a longitudinally disposed flange 24, which flange, in the case of the mandrels of the series 16, is downwardly extended while in the series 17 it is 'up? wardly extended. The series 16 normally remain on the table, butafter the metal has been shaped by forcing the two series together, as in Fig. 5, the series 17 is moved lengthwise from the,table and on to a support 25 adjacent to oneend of the latter, which support I have shown in Fig. 1 as being composed of a series of suitabiy mounted rollers. To prevent the completed sheet from passing off the table with'the series of mandrels 17, I employ a stripper 26 located .at one end of thetable and designed to probe moved latshown the-sevject into the path of the sheet to prevent it from traveling with the mandrels as they are withdrawn. This stripper I have shown as pivotally mounted on the underside of the table and as having a suitable manipulating handle. After the series of mandrels 17 has been withdrawn the corrugated sheet may be removed from the bed.

Initially, the sheet which is to be shaped is, by any suitable means, given the formation shown in cross-section in Fig; 4. There is no difficulty in so corrugating a sheet, but heretofore it has been practically impossible to form a sheet with corrugations having throats of less width than the oppositely extended spherical bodies. With the series of mandrels 16 sufficiently spaced apart on the table, the corrugated sheet is placed over them as shown in Fig. 4. Thereupon the series of mandrels .17 is slid longitudinally of the table and over the sheet, and caused to alternate with the mandrels 16. The several mandrels of the'two series will then be spaced apart as shown in Fig. 4. Thereupon the operator lowers the top or cover 6 and fastens it by lugs 9, and the operating shaft'being set in motion the eccentrics will force slide 12 forward,

causing the pusher 10 thereof to engage with the innermost mandrel as well as the inner edge of the corrugated sheet and force the: several mandrels together until they assume the compact arrangement shown in Fig. 5. The further revolution of the eccentries will withdraw the pusher, whereupon the operating mechanism is brought to a stop; the top or cover is then raised, and the corrugated sheet removed after the series of mandrels 17 has been drawn outwardly 'onto the support I 25. The corrugations formed in the sheet will freely yield in be- .ing drawn over the enlarged body portions 23 of the lower series 0 mandrels, The extent of the cooperation between the pusher'and the vertically disposed wall of the supporting table may be regulated by adjusting screws 4.

From what has been said it will be seen that by means of my invention I am enabled" to form corrugations of the character stated extending longitudinally of the sheet, thereby giving to the latter additional strength in the direction most desired. Sheets thus corrugated are especially designed for reinforcing concrete.

I claim as my invention 1. In a machine'for shaping metal from a corrugated sheet, two series. of dies or:

mandrels between which the sheet is compressed, the mandrels of each series being reversed in respect to the mandrels of the other series, a table supporting said mandrels, one series of mandrels projecting beyond the table at one end thereof, and the other series projecting beyond the other endaoaaoea uponwhich one series of mandrels may be I moved.

2. In a machine for shaping metal from a corrugated sheet, a table having a compressing chamber open at one side, two series of similarly formed but reversely arranged alternating mandrels located within said chamber, one series of mandrels projecting beyond the table at one end thereof, and the other series projecting beyond the other end of the table, the projecting ends of the mandrels having shanks and head blocks, the latter being formed with coincident openings, links having slots to accommodate said shanks, rods, projecting through the openings of the head blocks, a horizontally-movable pusher designed to enter the open side of said chamber to engage the adjacent mandrel and force the several mandrels together, and means for operating the pusher.

3. In a machine for shaping metal from a-corrugated sheet, a table "having ,a cornpressing chamber open at one side, two series of similarly formed but reversely ar-' ranged alternating mandrels located within said chamber, a horizontally-movable pusher designed to enter the open side of said chamber to engage the adjacent mandrel and force the several 'mandrels together, means for adjusting the position of the table relatively to the pusher, means for operating the pusher, a support adjacent to one end of the table ,onto which the mandrels of "one series are designed to be moved, and a stripper mounted on the table adjacent to said support for preventing the corrugated sheet from being withdrawn from the table with the mandrels.

4. In a machine for shaping metal'irom a corrugated sheet, a, frame, a table having a compressing chamber open at one side, a top or cover for extending over said chant ber, means for locking the top or cover to the table, two series of similarly formed but reversely positioned mandrels alternately arranged and extending longitudlnally of the table, a sliding member mounted on said frame, a pusher carried by said sliding member and located 'in line with and movable into said compressing chamber through the open side thereof', andmeans for reciprocating said sliding member.

5. In a machine for shaping-metal from a corrugated sheet, a frame, a table having a compressing chamber open at one side, a top or cover for extending over said chamber, means for locking the top or cover to ed on said frame, a pusher carried 'by said sliding member and located in line with and movable into said compressing chamber through the open side thereof, means for reciprocating said sliding member, a support in line with one end of the table upon which the mandrels of one .seriesare designed to be moved after the sheet has been formed, and a stripper for preventing the formed sheet from following said mandreis when being Withdrawn from the table.

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.
