SPECIFICATION forming e Letters Patent No. 532,471, dated January 15,1 895.

Application filed May 8, 1894:. Serial No. 510,458 (No modeL) To aZZ whom it may concern.-

Be it known that I, EDWARD O. MERSHON, a citizen of the United States, and a resident of Saginaw, in the county of Saginaw and State of Michigan, have invented a certain new and useful Cleaner and Oiler for Band Saw Wheels, of which the following is a specification.

My invention relates to means for keeping the wheels ofband-saws clean and free from gum or other obstruction.

The pitch and sawdust carried by a bandsaw onto the lower band-saw wheel, particularly, sticks to the surface of the wheel and obstructs the proper operation of the saw and by continued accumulation increases the diameter of the wheel and cracks the saw. Scrapers and brushes have heretofore been used to remove fromthese wheels this obj ectionable matter but if a soft brush or a scraper made of metal softer than the wheels is used it soon becomes dull and does not do the work satisfactorily. If on the other hand a hard metal brush or scraper is used it soon spoils the wheels bywearing away the surface thereof. Scrapers and brushes when used alone become also clogged with gum and require frequent cleaning. 1- overcome these difliculties by employing a specially constructed scraper and by using oil in connection therewith to prevent pitch and dust from sticking to the surface of the wheels and'to the scrapers and in fact to prevent the saw also from becoming clogged with gum.

With this end in view my invention consists in combining with a scraper, an oil well from which oil shall be fed to'the surface of the wheel to prevent gum from sticking and to dissolve or soften any which by chance might adhere.

It also consists in mounting in a particular manner a series of spring-toothed scrapers and in arranging the teeth of one scraper to alternate with'thoseof another.

. My invention further consists in the particular construction and arrangement of parts hereinafter specified and pointed out in the claims.

In the accompanying drawings forming a part of this specification,-Figure- 1, represents inside elevation my improved cleaner and oiler as applied. Fig. 2, shows a front view, and Fig. 3, represents a transverse ver= tical section taken on line as, 00, of Fig. 2.

In the drawings the dotted lines A, indicate the surface of the lowerband wheel. ,Above this wheel and nearly over the center thereof 1 I locate the combinedcleaner and oiler which may be supported in any convenient way, but which I preferably mount upon the frame or column of the machine.

B, refers to the oil wellwhich may be of any form or shape and of any suitable material. I have shown it as provided with a perforated flange O, at one side for attaching it to the frame or column of the machine and with a cover D, which may be hinged or otherwise retained in place, to keep sawdust and other matter from entering the well. The sides of the-oil well project beyond the front wall and form a recess or groove in which the scraper blades or plates E, are mounted.

Each blade of the scraper consists of a curved plate of spring metal preferably of brass, and is slit or serrated at itslower end. The slits and teeth of one blade alternate with those of another so that they shall scrape the entire width of the wheel surface.

In mounting the scraper, the first blade thereof is placed in the recess against abutments (1, a space being thereby left between said blade and the front wall of the well to ride over so much of a spot of gum as it can- 5 not remove without disturbing the other blades leaving them free to complete the re moval of said gum. The alternation of the teeth also assists in the speedy and complete removal of any gum, as that which 'might IOO pass between two teeth of the first blade will be caught by the middle of a tooth on the next blade. The spring action of the scraper blades also assists in keeping them free from the gum which they remove from the wheel, and to further assist them in freeing themselves from gum they are mounted so that they shall bear radially on the wheel.

Several different ways might be de vised for applying the oil, but I prefer to use a wick for that purpose. The front wall H, of the oil-well is, therefore, made shorter than the others or slotted near its upper edge to provide for passing the wick I, over the said wall and down between it and the scraper, as seen in Fig. 3. The overhanging end is sufficiently long to lie for a short distance on the surface of the pulley. It may also like the scraper be wide enough to extend across the surface of the wheel or it may be much narrower and may even not touch the wheel but simply deliver oil onto the scraper from which it will be conveyed to the wheel. Wicks of different capillary capacity may be used to regulate the amount of oil that shall be fed to the wheel. As the machine operates, the oil fed to the lower wheel is also transmitted to the saw and to the upper wheel and assists in keeping them free from gum. The usual scraper or brush may or may not be used on the upper band wheel when my improved cleaner is used on the lower one, but as a general rule it is advisable to use a light brush thereon.

In sawing lumber containing agood deal of pitch it is advisable to use the oiler and scraper on the upper wheel. This may be done by reversing the scraper blades and extending a stiff wick, such as a strip of felt, up through a slot in the cover-D, as indicated by dotted lines J, in Fig. 1, the device being then located on the cross-head or that part of the machine which carries the upper wheel.

The oiler and cleaner may also be adapted for application to the upper band wheel by extending the front wall H, as shown in dotted lines in Fig. 3, and slotting it as at J. Then the wick I, would be passed upwardly from the slot J, between the scraper and the said extension of the front wall, the scrapers being inverted from the position shown in Fig. 2.

\Vhat I claim as my invention is 1. The combination with a band saw wheel, of an oil well supported on the machine in proximity to the wheel for supplying oil to the surface thereof, and a scraper secured to the wall of said well and consisting of a series of spring metal plates arranged to bear radially upon the wheel, lugs upon the well separating the first plate therefrom, crosspieces between the other plates and on the outside of the last one, and screws passing through said cross-pieces and plates into said lugs to secure the scraper to the well and to allow freedom of motion to each plate for the purpose set forth.

2. The combination with aband-saw wheel, of an oil well, a scraper attached to a wall of the well and consisting of a series of spring metal plates separated from one another, and a wick extending from said well and passing between said Wall and the scraper.

3. The combination with an oil well formed with a recess in a wall thereof, of a scraper secured in said recess, and a wick extending from the well and passing between the scraper and said wall, as and for the purpose specified.

4. The combination with a band-saw, of an oil well secured to the column thereof and provided with a recess in front, a series of adjustable scraper blades located in said recess and afranged to bear radially upon the band-saw wheel, transverse strips separating said blades from each other, and a wick extending from within the well through the front wall thereof to said wheel.

5. A scraper for band-saw wheels consisting of a series of serrated spring metal plates or blades mounted to act radially and simultaneously on said wheel and spaced apart so that each blade may act independently of the other, the serrations of one blade alternating with those of another, as and for the purpose specified.

6. The combination with a band sawingmachine, of an oil well detachably secured thereto and provided with a recess in one side, a scraper fitted to said recess and provided with slots running longitudinally thereof to enable it to be adjusted and reversed for engagement with either the upper or the lower band wheel, and means for conducting the oil from said well to either of said wheels, substantially as and for the purpose set forth.

7. The combination with a band-sawing machine, of an oil well cast in one piece and provided with an ear for the attachment thereof to the frame of the machine, a cover for closing said well, a scraper attached to the front wall of the well, and a wick passing from the well through an opening in said wall and lying between the scraper and the wall, as and for the purposes set forth.

8. An oilerand cleaner for the wheels of band sawing machines, consisting of an oil well with an aperture at one side for the passage of a wick therefrom and with lugs between which said wick passes, a scraper fitted to that side of the well against said lugs thus forming a passage for the wick and provided with slots extending longitudinally thereof, and screws passing through said slots into said lugs for adjustably securing the scraper to the well.

9. An oiler and cleaner for band saw wheels, consisting of the oil-well provided with a recess in one side and an aperture opening into said recess, a wick passing from the well through said aperture and lying in ,the re- Signed at New York, in the county of New cess, a series of spring metal plates fitted to York and State of New York, this 19th day of said recess, cross strips alternating with said April, A.
