MACHINE FOR CORRUGATING- VENETIAN-BLIND STOCK.
Specification of Letters Patent.
Patented Jan. 26, 1915.
Original application filed July 30, 1913, Serial N 0. 782,110. Divided and this application filed March 27,
1914. Serial No. 827,754.
To all whom it may concern:
Be it known that I, J osnrn JEAN DUMAS, a citizen of the Republic of France, residing at Paris, France, have invented new and useful Improvements in Machines for Corrugating Venetian-Blind Stock, of which the following is a specification.
My invention relates to a machine for forming metals to be used in the manufacture of Venetian blinds, and reference is made to my prior application numbered 782,110, filed July 80, 1913, for manufacture of metal Venetian blinds, of which this application is a division and in which the subject matter hereof was disclosed.
The principal object of my invention is to provide an efficient and convenient machine for corrugating metal to be used in the manufacture of Venetian blinds.
A second object of my invention is to provide a machine adapted to corrugate the edges of metal sheets irrespective of the thickness of the sheet or the width thereof, and irrespective also of the depth of the corrugations desired.
A third object of my invention is to improve the process of manufacturing Venetian blinds having corrugated edges.
A final object of my invention resides in the particular arrangement and combination of parts hereinafter described.
In the accompanying drawings: Figure 1 is a vertical longitudinal section through my improved machine taken approximately on the central line thereof. Fig. 2 is a cross section along the line A-B of Fig. 1. Fig. 3 shows three successive phases of the process of corrugating the edges of a sheet of metal to be used in making a Venetian blind.
Throughout the separate views the same part is designated by the same reference character.
Referring more particularly to the drawings, it will be seen that I provide a frame 11 above which is a large plate 15 which is let into a recess in the top of the frame or plate 11. Projecting upwardly from the plate 15 and integral therewith are two standards 12 and 1 1, respectively, set at the ends of the base plate, and intermediate standards 12 and 14 is a third standard 13 which is adj ustably mounted on the plate 15,
said plate being provided with a longitudinal slot 15 into which slot projects a part 13' integral with the standard 13. Suitable means are provided, such as a threaded rod 22, by which the standard 13 can be advanced forward or retracted from the standard 12. Rod 22 has threaded engagement with a nut 22 placed within the projection 13 and I provide a clamping plate 23 which is rigid with a threaded bolt such as 23 which also projects into the nut 22 and has threaded engagement therewith. It will be seen that by turning up the plate 23 so that it will bear against the under side of the plate 15 on opposite sides of the slot 15, that the standard 13 may be locked in adjusted position.
Journaled in the standard 12 are three pairs of shafts such as l616 at the ends of which are cooperating corrugating elements such as a, the elements a bemg on the side toward the standard 13. At the opposite ends the shafts 16 are intermeshing gears such as 1717. Journaled in the standards 13 and 14: are three pairs of shafts 16 and 16 which also carry corrugating elements a on their ends toward the standard 12. Shafts 16 and 16 have collars fixed thereto on opposite sides of the standard 13 so that the shafts are moved longitudinally whenever the standard 13 is moved. It will be seen moreover, that the ends of the shafts 16-l6 opposite the corrugating element a, are slotted as shown at 1616 so that they can be driven by the gears 17-l7' while permitting axial or longitudinal adjustment. It will be seen that the gears 17l7 are mounted intermediate the standard 24: and a plate 18 so that the gears 17 cannot move with the shaft 16.
In order to accommodate plates of different thickness and to vary the depth of corrugations, I arrange the per shafts inboth 16 and vertically adjustable. For this purpose I provide a threaded rod such as 24 which is attached to each of the upper bearings and they extend through the top of the corre sponding standard. Hand wheels 3535 are mounted on the rods 24: above the standards so that the bearings can be lifted or lowered by means of the hand wheels. Lock bearings of up- 16 so as to be nuts 25 are also provided for holding the bearings and shafts in adjusted position.
As clearly shown in Fig. 3, there are three pairs of rollers A for each edge of the sheet to be corrugated, and these rollers are suitably secured to the ends of the shafts 16 and 16. Consequently the operation is effected in three successive passes. The outline or profile of the rollers consequently progresses as indicated at m, g z in Fig. 3 from the inlet to the outlet of the machine, so as to facilitate the operation. Shaft 19 transmits movement to a shaft disposed intermediate between itself and the last one of the lower tier of shafts. An intermediate shaft is disposed also between each of the lower roller shafts, the upper shafts being driven from the lower shafts by the pinions 17 and 17. The first one of the upper roller shafts also gears with an intermediate shaft which drives two feed cylinders 20 and .91 arranged across the space between the standards 12 and 13 and between which the leaves are successively engaged. The upper feed cylinder is pressed down by the action of a spring permitting it to give in case of any irregularity of the metal sheet, so that the latter are not subjected to any rolling.
It will be seen from the preceding that the corrugating tools act simultaneously on both edges of the sheet and that the latter are corrugated progressively. Moreover, the movable standard 13 is displaced according to the width of the leaves to be corrugated. Moreover, the three passes referred to above for the purpose of corrugating are not absolute, but the number may vary without affecting the invention. The term applies to the general dimensions of the machine. The latter may be of any size and provided with any driving device whatsoever.
It will be seen that my machine is particularly suitable for the manufacture of Venetian blinds, and in addition to the simplicity of its construction and the facility with which it can be worked, it is particularly characterized by the special arrangement of the different parts permitting the corrugation of leaves of any length and forming corrugations of substantially different depths, whatever may be the thickness of the sheet metal employed.
Having thus described my invention, what I claim is 1. A machine for corrugating metal sheets comprising a frame, two oppositely disposed upright standards mounted on said frame, said standards being fixed with respect to each other, a third standard mounted between said first mentioned standards and laterally adjustable with respect thereto, superposed corrugating elements carried by one of said first mentioned upright standards, superposed corrugating elements disposed in the other of said first mentioned upright standards and also carried by said third standard said last mentioned superposed corrugating elements being laterally adjustable with respect to said first mentioned corrugating elements, thereby adjusting the said machine to corrugate sheets either at both edges or intermediate the edges, and means for clamping said laterally adjustable standard.
