6 Claims. l This invention relates to a device for removing or wiping oil from the hand or hands of a machine mechanic or operative.

The prime object of my present invention centers about the provision of a device capable of functioning effectively for removing lms or coatings of oil covering the hand or hands of a mechanic or operative tending oil consuming or using machines such, for example, as automatic screw machines, turret lathes and the like.

It has been for years common practice in factory plants and machine shops to use cotton waste and cleansing cloths for cleaning or wiping oli oil films and coatings adhering to the hands of machine mechanics tending the oil tanks and oil circulation systems of various machines. Besides the undesirable wastage of such cleansing articles, they are nearly always unhandy as-well as untidy and they will perform their intended purposes.

The device of the present invention, having for its aim the replacement of such cleansing articles with an al1-effective oil cleaning device, is' characterized by the following structural and functional features:

(1) It is capable of performing its function of removing or wiping off the oil films or coatings covering and adhering to the hands of the mechanic, with thoroughness and efficiency.

(2) It does not involve wastage of material and may be used and re-used almost indefinitely for the purpose.

. (3) It may form a xture made, for example, in the shape of a machine attachment so that it is always located in a known position, handy and ready for use. y

(4) It may be so constructed and designed as to oil-clean all parts'and surfaces of the hands of the operative.

(5) It may be used with great rapidity `and satisfying convenience and may be made at an exceedingly low cost.

To the accomplishment of these objects and purposes and such other objects as may hereinafter appear, my invention relates to the oil removing or wiping device sought to be defined in the appended claims and described in the accompanying specification taken together with the drawings thereof, in which:

Fig. 1 is a front elevational view of the oilcleaning device of my present invention, showing one form which it may take;

Fig. 2 is a view thereof Ltaken in cross-section in the planes of the broken line 2--2 of Fig l;

Fig. 3 is a top plan view thereof;

Figs, 4, 5 and 6 are sectional views thereof drawn to a reduced scale and illustrating the functioning thereof and the manner of itsuse. Of these figures:

Fig. 4 illustrates the oil-cleansing ofthe palm of the operatives hand;

Fig- 5 illustrates the cleansing of the front of the fingers and may be also considered illustrative of the manner of cleansing the back of the fingers of the operatives hand; and

Fig. 6 illustrates the cleansing of the back of the operatives hand; and

Fig. 7 is a perspective view showing how the device may be attached to the head of a turret lathe.

Referring now more in detail to the drawings and having reference first to Figs. 1 to 3 thereof, the oil-removing device of the present invention comprises a number of wiper blades B', B2. and B3, so constructed and so spacially arranged that the operative by one continuous sweep of either hand over the device may effectively wipe or scrape olf all of the oil adhering to the front of the hand, and by a return continuous sweep of the hand over the device may effectively wipe or scrape off all of the oil adhering to the back of the hand.

The wiper blade B' may comprise a piece'of sheet metal contoured as shown in Figs. l, 2 and 3 of the drawings, the exposed or top edge in of which. is line-shaped to t across the palm of the operatives hand. For this purpose the edge lil may be a straight knife edge, although it will be understood that the line-shape thereof may be varied or modified.

The wiper blade B2 may also comprise a piece of sheet metal, contoured and shapedas depicted in Figs. l, 2 and 3 of the drawings, the exposed or top edge l2 of which is recess-shaped so as to iit partway around individual fingers of either hand of the operative. More specifically, this edge I2, also a knife edge, is provided with a plurality such as the four recesses or concave depressions lli, Mshaped to receive and fit .partway around the individual four fingers of either of the operatives hands.

The wiperblade B3 may also comprise a piece of sheet metal contoured and shaped'as depicted in Figs. l, 2 Aand 3 of the drawings, the exposed edge 16 of which is line-shaped tol fit across the back of the hand of the operativa'this exposed edge being preferably a knife edge curved as best shown in Fig. 3' ofthe drawings to fit the back of the operativeshand.

Thesewiper blades B', B2 and B3 are relative- 1y arranged and spaced so as to carry out the functions above described and best illustrated in Figs. 4, 5 and 6 of the drawings. These three blades are also secured to-gether so as to form one operative unit or tool. More specically considered, the blades B' and B2 are so spacially arranged and the edges I0 and I2 so relatively disposed that with one continuous sweep of the hand, say in a downward direction, the surfaces of the front of the operatives hand are oil-wiped as will be described more in detail presently; and the blades B3 and B2 are so spacially arranged and the edges I6 and I2 thereof so relatively disposed that with a return continuous sweep of the hand, say in an upward direction, the surfaces of the back of the operatives hand will be oilwiped as will also be described more in detail presently. It will be noted that the fingerwiping blade B2 is arranged between the wiping blades B' and B3 and is common thereto; that is 'to say, it serves its finger-wiping function, rst in conjunction with the wiper blade B and then in conjunction with the wiper blade B3. The blade B3 may be secured to the blade B2 as'by brazing or spot-welding the base I8 of theblade B3 to the intermediate connecting part 2E! of the blade B2. Similarly, Vthe blade B2 lmay be secured to the blade B as by brazing or spot-welding the base 22 of the former to the base 2i of the latter. It Ywill be also noted that the knife edges Ill-and I2 of the blades B' and B2 face generally in an upward direction, while the knife edges I2 and I6 of the blades B2 and B3 face generally in an angular and even horizontal direction so that Vthe most convenient downward and return upward sweeps of the hand may be used in the cleansing movements.Y

' Figs. 4 and 5 taken together illustrate the use Y and operation of the oilcleaning device for cleanlingall of the surfaces of the front of the operatives hand. The hand is first moved in one continuous sweep as indicated by the arrows 26,

26 vin Figs. 4 and 5 of the drawings from theY wrist to the ngertips. The first movement is with the palm p of thehand scraping against theline-shaped edge of the yiirstblade B', thus scraping off the oil lm o from the surfaces of the palm. This movement continues until the base of the fingers f of the operative meet and are ready to be tted into the recesses or depressions Id, It of the blade B2. From this point on the movement and action proceeds as illustrated in Fig. 5 of the drawings. The continuing movement of the hand in the arrowed direction results in scraping or wiping on the oil film adhering about the fingers of the operative. Since the four groovesor recesses I4, I4 fit partway (somewhat more than midway) around the individual ngers'of the operatives hand, it will be seen that with the completion of the stated directional sweep of the hand over the cleaning device, all of the surfaces of the hand including the palm and fingers, which may be described as the front of the hand, are thoroughly oilscraped or wiped in the operation of the device.

Figs. 6 and 5 taken together illustratethe use and operation of the oil-cleaning device for cleaning all of the surfaces of the back of the the parts of the device Without departing from.

operatives hand. The hand is rst moved in one V return continuous sweep as indicated by the arrows 28, 28 in Figs. 6 and 5 of the drawings, again from the wrist to the fingertips. The rst movementv is with the back of the hand b scraping against the line-shaped or curved edge of the blade B3, thus scraping or .wiping oif the oilvlm around the individual fingers, it will be seen that` with the completion of the stated return directional sweep of the hand over the cleaning device, all of the surfaces of the hand including the back and the fingers, which may be described as the back of the hand, are thoroughly oil-scraped or wiped in this return operation.

For oil-cleaning the sides of the hand as well as the surfaces of the thumb, at least one of the wiping blades and preferably the wiping blades B' and B2 is or are provided at its opposite sides with curved edges adapted for fitting and for scraping engagement with the sides of the operatives hands. Thus the blade VB is provided with opposite curved scraping edges 3B, 30 and the blade B2 is similarly provided with the opposite curved edges 32, 32.

The unitary device comprisingthethree blades B', B2 and B3 may be formed as shown, so that the same may comprise a suitable machine at- Y tachment. Thus the produced unit may be secured to an angle bracket 34 byumeans of the` bolts 36, and this angle bracket may serve as the means for supporting the device ori-the head 36 of a suitable oil-consuming or using machineY such as a turret lathe -or automatic screw -ma, chine or the like, as best illustrated in Fig. 7' of the drawings. When soattached to a machine, the device is in an accessible location ready an handy for use whenever needed.

The construction, operation and use of the oil-cleaning device of the present invention will be apparent from the above detailed description thereof. vantages described therefor are all obtained'in its operation and use. Itgwill be seen'that the device is capable of performing its cleansing Y clean all parts and surfacesof both hands of the user. It may be used to clean any foreign {substance adhering to the hands suchv as paints, molasses, etc.; and whereverthe rword oil has :been used herein, it will be understood to include any foreign matter adhering to the users hands. The device obviously may be used with great rapidity. Its construction is simple andmay be made4 at an exceedingly low cost..y Y l Y It will 'further be apparent that changesmay be made in the construction and arrangement of the spirit of the invention defined in the follow.'- ing claims. -Iclaimr *7.
