comme.' ((1184-64) This invention relates to a device for lubri^ or while 'it is at rest; 'Otherwise spots or stains may be causedwhich willlseriously damage the goods being sheared.
It is the general object of my invention to t kprovide an improved construction of lubricating device for such purposes, which may be economically manufactured and conveniently applied to either old or new machines.
A further object is to provide a lubricating device which is reliable in operation and which requires no attention by the operator toprevent continued delivery of oil by the lubricating de- I vice when the machine is stopped.
My invention further relates to arrangements and combinations of parts which will be hereinafter described and more particularly point-ed out in the appended claims.
A preferred form of the invention is shown in the drawing, in which:
Fig. 1 is a sectional side elevation of certain parts of a cloth shear, with my invention applied thereto;
Fig. 2 is a sectional plan View, taken along the line 2-2 in Fig. 1; and
Fig. 3 is a combined sectional and perspective view of the lubricating device.
Referring particularly to Fig. l, I have shown portions of a cloth shear including a revolving cutter l having a plurality of helical blades Il, a xed blade I2, a cloth rest I4 over which the cloth C is drawn closely adjacent the fixed blade l2'and revolving cutter lll, a xed support I5 for the blade I2, and an exhaust hood I6 by which lint and waste are removed from the shearing point. The parts thus far described are of a usual construction in cloth shears.
My improved lubricating device extends the full length of the revolving cutter l0 and preferably comprises a sheet metal trough 20 havingV an upright rear flange 2| and a forwardly and horizontally extending front flange 22, the outer end of which is doubled and bent downward, as indicated at 23.
A cover 30 is provided for thetrough 20, and the rear portion 3| of the cover is o'set upwardly and then bent downwardly, providing a" .lll
U-shaped sectionto embrace and form a close i joint with the upstandingv rear flange 2| of the trough 20. i
The front portion of the vcover 30 is bent upwardly as'indicated at 33, and is provided with a doubled inclined portion 34 forming a shield l for the rapidly revolving cutter. strip of leather L is clamped between the cover*A 3l) and the horizontal flange 22 of the trough 20 by a series of clamping screws 40, provided An elongated in spaced relation the full length ofv the oilingf device.' l
The inner end' of the leather strip L extends downward to' thefbottom ofthe trough 20, -as
` clearly shown in Fig. 3, and substantially below the level of the `oil supply maintained therein. A movable oil cap 42 covers an opening in 'the top 30 through which the oil supply may be replenished. y
The lubricating device is preferably mountedY on curved arms 50 having slots 5| to receive clamping screws 52 on the exhaust head I6. The outer edge 6|] of the leather strip L is to be carefully trimmed to present a straight surface, and the lubricating device is to be adjusted toward the revolving cutter blades until it is just possible to see light between the edge of the leather and the edges of the blades.
With the parts thus constructed and adjusted, it is found that a sumcient supply of oil` will be drawn upward through the leather L by capillary attraction or wick-like action, so that the edge B0 will have an extremely thin lm of oil thereon which is continuously transferred to the rapidly revolving cutter blades as they pass closely adjacent thereto with a wiping effect but preferably with no actual contact between the blades and the leather strip.
Consequently, no substantial wear of the edge 60 of the leather strip occurs, `and furthermore, the edge is not hardened by repeated blows of the blades thereon.
It will be noted that the edge of the leather strip L is substantially above the level-of the oil in the trough 20, so that even when the machine is at rest there is no tendency of the `leather to v syhon out excess oil nor to empty the trough, as
adjustment when the direction of rotation of the revolving cutter is reversed. This is very important in certain types of machines in which the cutters are repeatedly reversed during the operf ation of the machine.
This lubricating device has been found much more satisfactory than leather flaps resting on the revolving blades, which have been heretofore commonly used and which required frequent removal and more or less prolonged soaking in oil when the oil therein was exhausted.
It thus appears that my improved lubricating device solves a somewhat troublesome problem of long standing which presented diiiiculties not heretofore satisfactorily overcome.
Having thus described my invention and the advantages thereof, I do not wish to be limited to the details herein disclosed, otherwise than as set forth in the claims, but what I claim is:
1. A device for lubricating rotating cutter blades which comprises an elongated oil-holding trough, an elongated oil-absorbent strip, and means to clamp said strip in fixed relation to said trough, with its inner edge immersed in oil in said `trough and with its outer edge projecting beyond said trough and substantially above the normal oil level in said trough, and firmly supported in close proximity to the locus of movement of the edges of said rotating cutter blades but out of actual contact with said blades.
2. A device for lubricating rotating cutter blades which comprises an elongated oil-holding trough having a horizontally extended top flange, a cover for said trough, an elongated leather strip Vwhich delivers oil directly to said revolving blades,
means to clamp said strip between said flange and said cover with its inner edge immersed in oil in said trough and with its outer edge projecting beyond said flange and cover, and means to rmly support said device in fixed position with the projecting outer edge of said leather strip closely adjacent the edges of the revolving cutter blades but out of actual contact therewith and substantially radial to the locus of movement of said blades.
3. A device for lubricating rotating cutter blades which comprises an elongated oil reservoir, and an elongated strip of material having capillary qualifications, one edge of said strip being immersed in oil in said reservoir, and the other edge being presented at a higher level close to said rotating cutter blades but out of actual contact therewith, and said latter edge being supplied by capillary action with a thin lm of oil which is removed by said rotating blades and which is replenished as fast as it is removed.`
4. A device for lubricating rotating cutter blades which comprises an elongated oil reservoir, an elongated strip of material having capillary qualications, one edge of said strip being` immersed in oil in said reservoir, and the other edge being presented at a higher level close to said rotating cutter blades but out of actual contact therewith, and a cover plate secured to said reservoir and clamping said strip in position, said cover plate having an inclined portion projecting upwardly from said reservoir and forming a guard for the revolving cutter blades.
