LEADER PIN OILER Filed March 4, 1938 Patented Nov. 28, 1939 UNITED STATES.
eAT-ENT OFFICE 6 Claims.
This invention relates to improvements in oilers and more particularly to devices designed for lubricating the leaderpins used in connection with punch press die sets. 'The device is adapted to provide an efiicient oiling means for leader pins and may be used in connection with any of the usual die sets without material change in any of the elements of the set. The device is adapted to be self-supporting and automatic in operation when once inserted in place and to retain a supply of oil or other lubricant and keep the pins properly lubricated at all'times.
It is an object of the present invention to provide an oiler which will apply lubricant overthe 5,;cylindrical surface of the leader pins with each operation of the punch press and which may be so positioned with respect to the punch holder and shoe that it will not interfere with the usual operation of the die sets. Also provisionis made 20, whereby an additional supply of lubricant may be added as required.
A further object is the provision ofa leader pin oiler which may be applied to any ordinary die set and will be of few parts; cheap to manug5 facture, easy to assemble, and will not easily'get out of order in use.
The device also may be manufactured and sold independently of the die set and. may be applied thereto by the user without change in the die set or oiler and without the use of tools or any aux- "iliary means for securing the oiler in place.
Further objects will be apparent from the.
specification and the appended claims.
In the drawing, Fig. 1 is a vertical sectional view through a die bodiment of the invention.
Fig. 2 is an expanded perspective view in longitudinal section of the oiler housing.
Fig. 3 is an enlarged fragmentary sectional View through the'assembled housing and corresponds to a portion of the housing shown in section in Fig. 1. Fig. 4 is a top plan'viewof one form of wick adapted for use in the oiler housing.
Referring to the drawing in detail, the embodiment illustrated comprises a die shoe I having leader pins 2 preferably rigidly secured therein and extending upwardly in parallel relation.
through suitable holes in a punch holder 3. The
set and one of the oilers and illustrates one em-.
metal container member or'housing member 5 having an inner upturned flange 6 and an outer upturned flange 1 spaced therefrom to provide an annular trough therebetween. This construction provides an annular lubricant chamber 8 in the container.
A container cover" 9 is provided. and is constructed very similar to the container 5, but slightly smaller in outside diameter and is provided with an inner downwardly extending flange ill and an outer downwardly extending flange l I, which latter substantially corresponds in width to flange T! of the container 5. The cover member. 9 is of a suitable size to telescope within the container 5 as illustrated and to form a wick holding A ring-like wick i2 is inserted between the members 5 and 9 and, when these members are telescoped together, the wick member is compressed in such a manner that an annular portion extends inwardly between the fiangest and If) in a position to contact with a leader pin when the device is placed thereon.
The wick may be a ring or washer of felt or other suitable material such as illustrated in Fig. 4, or it may be merely a suitable strip of a desired cross section and of suitable length to extend completely around the leader pin. I
f'A body member l3 is'also provided and, if desired, may be identical with the member 5. In
fact, an identical member may be used and. merely inverted as illustrated in Fig. 3 and soldered or otherwise secured to the bottom of the member 5 as shown at M. It willbe understood that, by this construction members 5 and I3 may be interchangeable and may be formed by the same tools therebyproviding a very cheap construction.v A coil spring 15 is provided which is of sufficient diameter to receive the leader pin 2 therein and the, oiler housing is supported on the upper end of this spring as illustrated in Fig. 1. If desired, the upper end of the spring may be secured in the housing l3 by soldering or any other suitable means. The spring preferably is of sufficient length to always retain thehousing against the punch holder during any position of the holder so that the oiler housing follows the holder at all times and the felt wick effectively lubricates the pin over its length with each operation of the punch press.
An oil hole I6 is provided through the flange l of the housing member 5 and a corresponding hole I! is provided through the flange ll of the covermember 9. These holes are positioned so that they are in alignment when the device is assembled so that lubricant may be applied to the wick as required.
The device provides many advantages over ordinary methods in that it may be applied to ordinary die sets without change in any part of either the set or the oiler, and without the use I of special tools. The oiler device may easily be removed and replaced and new wicks may be inserted by merely removing the cover member I I.
Modifications may be made withoutdeparting from the spirit of the invention. It is desired, therefore, that the invention be limited only by the prior art and the scope of the appended claims.
