Description

H. J. ZENNER.
OILER FOR PUNCH PRESSES AND THE LIKE.
APPLICATION FILED JULY 1. I919.
Patented Nov. 4, 1919.
HUBERT J. ZENNER, OF RACINE, .WISCONSI N.
OILER FOR PUNCH-PRESS'ES ANT) THE LIKE.
Application filed July 1, 1919.
. To all whom it may concern:
Be itknown that I, HUBERT J. ZENNER, a citizen of the United States, and resident of Racine, in the county of Racine and State of Wisconsin, have invented certain new and useful Improvements in Oilers for Punch- Presses and the like; and I do hereby declare that the following is a full, clear, and exact description thereof.
My invention relates to new and useful improvements in devices for applying a coating of oil or other liquid to the surface of a sheet of work material, and it is more particularly directed to the provision of a device for oiling strips of sheet metal as they are fed into a punch press or similar machine, the present device being of the type shown in my co-pending application for patent filed March 29, 1919, Serial No. 286,208 and comprising a pair of superposed receptacles between which are disposed a pair of rollers resiliently urged together for oiling a strip of work material passedbetween the rollers.
It is in general the object of my invention to simplify and otherwise improve the structure and to increase the operative efficiency of devices of this character, and it is more particularly my object to provide a device of this character wherein the entire body structure may be formed of a single simple casting to thus provide a durable structure and promote economy in manufacture.
A further and important. object resides in the provision of an arrangement for guiding the work material between the rollers which prevents gouging or other damage to the rollers as the edge of the work material is inserted therebetween.
With the above and other objects and advantages in view, which will be apparent as the description proceeds, my invention resides in the novel features of construction, combination and arrangement of parts which will be hereinafter more particularly described and defined by the appended claims.
In the accompanying drawings:
Figure 1 is a front elevational view of an oiling device constructed in accordance with my invention, one side portion of the device being broken away.
Fig. 2 is a transverse through the oiling device.
Referring now more particularly tothe sectional View Specification of Letters Patent.
Patented Nov. 4, 1919.
Serial No. 307,892.
accompanyin drawings, the body of my improved oiling device comprises a single casting formed of. end walls 5 which are common to a pair of superposedreceptacles A and B constituted in the device and which thus hold the receptacles in. spaced relation. The upper receptacle A is completed by side walls 6 and a bottom 7 extending'between and integrally connected with the upper portions of the walls 5, while the lowerreceptacle is completed by sidewalls 8 and a bottom 9 extending between and integrally connected with the lower portions of the walls 5, the corresponding portions of the Walls 5 being inclined in conformity with the inclination of the side receptacle walls 6 and 7 and the inclination of the upper edge portions of the walls 5 is carried into the intermediate portion of the walls 5 and merges into outwardly curved edge portions of said walls whereby to reduce the width of the walls between the receptacles. A guide ledge or table 10 extends horizontally inward from the upper edge of one of the side walls 8 of the lower receptacle and terminates short of andadjacent the central portion of the receptacle, for guiding work material between the rollers, later tobe described, and an attaching portion 11 depends from the bottom. of the lower receptacle for connecting the device with a suit able support, although other means of support may be employed. I thus provide .an integral body structure which may v be formed by a single simple casting.
A journal shaft 12 extendslongitudinally through substantially the central portion of the lower receptacle B and through the ,adjacent portions of the endwalls 5, being retained in place by nuts 13 threaded on its ends, and a. roller 14 is mounted on the shaft within the receptacle and carries a .facing 15 of felt or other suitable material, theperiphery of this facing being substantially tangential to or extending slightly above the upper surface of the guide ledge or table 10. The intermediate portions of the end walls 5 are provided with vertically elongated slots 16, and the shaft 17 is passed between the walls and through the slots, being retained in place by nuts 18 or other holding means on its outer ends. A second roller 19 is mounted on the shaft 18, and carries a facing 20 of felt or other suitable material. It will be noted that while I have described the rollers as being mounted on shafts extending through the device, the end portions of the shaft constitute pintle projections at the ends of the rollers and may be hereinafter so termed. The bottom 7 of the upper receptacle is provided centrally with a longitudinal series of apertures 21 preferably in the form of drill holes whereby their size may be accurately determined, these apertures permitting the oil in the upper receptacle to drip onto the upper roller.
To provide an arrangement urging the upper roller downwardly, a vertical enlargement 22 is formed on the outer surface of each end wall 5 between the slot 16 and the upper edge of the wall, this enlargement being provided with a longitudinal passageway 23 therethrough which communicates with the slot. A plunger rod 24 is disposed in the lower portion of the passageway and and this pressure may be adjusted by screwing the plug 2 5 inwardly or outwardly.
In the operation of the device, an adequate supply of oil is maintained in both the upper and lower receptacles A and B, the oil in the upper receptacle constantly dripping onto the roller 19 to afford its supply of oil and any surplus supply which is not distributed on the work strips is obviously caught in the receptacle B. It is noted that the inner edge of the ledge or table 10 is beveled so that the upper surface of the table extends very close to the juncture of the felt surfaces of the roller, and in inserting a strip of work material in the device, the forward edge of the strip is slid along on this table and meets the rollers at the junctures of their peripheral surfaces to thus prevent gouging of the lower roller immediately which might otherwise occur were the strip of work material permitted to engage the same below its juncture with the upper roller. The vertical enlargement 22 of the end walls, in addition to forming a complete housing of the roller pressing means, also strengthens said end walls.
An exceedingly simple, durable and efficient device is thus provided for the purpose described, and while I have shown a preferred embodiment of my invention, it will be appreciated that various changes and modifications of structure may be employed to meet diifering conditions of use and manufacture without departing in any manner from the spirit of my invention as claimed.
