Application February 2, 1949, Serial No. 74,053

19 Claims. (01. 15-236) This invention relates to a devicefor 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 films or coatings of oil covering the hand or hands of a mechanic or operative tending oil consuming or using machines such as automatic screw ma- In my Patent No." 2,425,526 of August 12, 1947, I disclose such a device which is characterized by the following structural and functional features:

1. It is capable of performing its function of I removing or wiping oif the oil films or coatings covering and adhering to the hands of the me- 'chanic, with thoroughness and efiiciency.

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 fixture made, for example, in'the shape of a machine attachment so that known position, handy and ready for use.

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.

In' actual use, the device of said previously issued patent has proved extremely effective to attain the desired objectives. However, it

has been found that when such a device is used over a period of time, the oil'or grease which is wiped from the operatives hand by the device accumulates'on the 'device, and particularly on a clean condition but also increasing the likelihood of slipping, thus making working around the machine a more hazardous task. The result is both unsightly and unsanitary.

It therefore has been found desirable to modify the construction disclosed in the previously issued patent so as to provide means on the interior of the wiper for collecting the oil and grease which is wiped from the hands of the user, thus preventing the accumulated oil and grease from escaping onto the equipment or the floorand facilitating disposal or reuse of the wiped oil or grease. Not only does this make the wiper more sanitary and the surroundings cleaner, but also, by confining the wiped waste material to an enclosed receptacle, eliminates the possibility that, by reason of accidental contact, said waste material might soil the hands or clothing of passers-by.

As pointed out in the previously issued patent, the wiper is most convenient in use when three wiping blades are presented for use, one for wiping the back of the hand, one for wiping the palm of the hand, and one for wiping the fingers. However, as is pointed out in said previously issued patent, an effective wiper can be constructed formed of only twowiping blades, one for the fingers and the other for the back and the palm of the hand. The present invention is specifically disclosed in the three-blade form,

.two of the blades coacting with additional two of the blades so as to define a receptacle, it

is possible to form the wiper integrally as by means of a one-piece casting, thus reducing the cost of production and at the same time giving rise to a more attractive unit which is possessed 'of the above. described advantages, and this without sacrificing any of the functional attributes set forth in said previously issued patent.

It is therefore an object of the presentinvention to devise a hand wiper which is more pleasing in appearance and more sanitary and economical in use than the previousv embodiments thereof.

Yet another object is to devise such a hand wiper which is so constructed and arranged that the oil or grease wiped from the hand of the operative is caused to collect in a receptacle from which it may conveniently be dispensed for disposal or reuse. l

A still further object of the present invention is to devise such a wiper which is adapted to be secured in an operative position on a bracket, the bracket being secured to a machine or other object, the wiperbeing capableof ready removal from the bracket in order to facilitate disposal of the wiped oil or grease which has collected therein. If desired, the wiper may be secured to a bucket or pail without having to use a special bracket. l

.the appended claims and as described in this specification, taken together with the accompanying drawings, in which: 77

Fig. 1 is a perspective view showing how the device may be attached to the head of a turret lathe or the like;

Fig. 2 is a front elevational view of the wiper of the present invention;

Fig. 3 is a side cross-sectional view taken along the line 3-3 of Fig. 2;

Fig. 4 is a top view thereof;

Fig. 5 is a rear elevational viewthereof;

Fig. 6 is a side cross-sectional view similar to Fig. 3 but showing the wiper secured to'the bracket and illustrating one mode of use of the wiper; and

Figfllis a view similar to Fig. 6 but showing another mode of use thereof.

The oil removing device of the present invention comprises a plurality of wiper blades generally designated A, B and C so constructed the device may effectively wipe 'or scrape off all of the oil adhering to the other side of the hand.

A receptacle generally designated D is defined between two of the wiper blades, here shown as the blades A and B, the receptacle D being adapted to catch all of the'oil or grease asit accumulates until it is desired to dispose Troughs generally designated E and E are provided on the exteriorof the wiper blades A and B respectively, the trough E" being defined by the blade.(:, and communicating passages F are provided between the troughs E and'E' 'and'the receptacle D so that oil or grease which runs down'the outer surfaces of the wiper blades A and B or the inner surface "of the blade C will find its way into the receptacle D.

The wiper 'ofthe present invention will preferably take the illustrated form of a one-piece unit which may be conveniently formed in a single "casting operation. Such a construction hasthe advantage that the unit is s'eamle'ssand consequently thepossibility of leakage of oil or grease is almost entirely eliminated. lit is, how- 'ever,-definitely within the scope of the present invention to make the wiper of a plurality of 7 units assembled to ether.

tives hand.

Ihe wiper blade A terminates in an upwardly disposed wiping edge 8 which is line-shaped and which may, if desired, take the slightly curved I form illustrated in the drawing. It is the edge 8 which is particularly adapted to scrape the palm of the operatives hand. The wiper blade A is provided at its sides with two raised portions II] which serve the dual purpose of scraping the sides of the operatives hand and of guiding his hand as it is being swept across the blades A and B.

The wiper blade 0 terminates in an upwardly disposed wiping edge II which may be slightly concave in shape as viewed from above (see Fig. 4), this edge ll being particularly adapted to scrape the back of the operatives hand. It will be noted that the edge .I lis disposed somewhat below the wiping edges/2 and 8 of the wiping blades B and A respectively, this arrangement being preferred in order to facilitate use of the device as described hereinafter.

These wiper blades A, B and C are relatively arranged and spaced so as to carry out the functions above described and best illustrated in Figs.

"Band 1 of the drawing. These three blades are also secured together so as to form one operative unit or tool. More specifically considered, the blades A and B are so spatially arranged and the'edges'Z and 8 are so relatively disposed that with one continuous sweep of thehand the surfaces of the palmand front of the o'peratives hand are oil-wiped, and when the operatives hand is inverted and'then swept across the blades "B and C, the surfaces of the other side'of his hand are oil-wiped.

The blades Aand B extend upwardly from and are connected to a first wall 12 in the form of a base and side walls 14 and 16 extend upwardly from the first wall l2 and between the blades A and B. Consequently, an enclosed's'pace which constitutes the'receptacle D is defined between the blades A and B, the first wall l2 and'the side walls l4 and It. 'It will be apparent that any oil scraped from the 'operatives hand by the interior surface of the wiper blades :Aor B v'vill run down along that interior surface into 'the receptacle D. However, it often happens, as

will be explained more in detailhereinafter, that oilis wiped from the -operative s hand-along the exteriorsurface of the blade-AorB. In-order to ensure that this-oil is also led to the receptacle D, troughs E and E are formed onthe exterior surfaces of each of the blades'A and B, the trough E being defined by the lip 20 conwiper blades A and B at 'the bottom of the troughs E and E so that any oil and grease which is caught by the'troughs E and E will pass intothereceptacle D, the orifices 22-and 24 thus constituting the communicating passages F.

Depending from thefirst wall l2 are a pairof arms 26 and 28 spaced from one another so as to fit over the upstanding end 30 of a bracket 32 which is adapted to be secured in anyappropriate manner to aturret lathe or any other piece of machinery 34 in connection with which the use of the wiper is desired. The arms 26 and 28 are appropriately apertured as at 3B and 38, the aperture 36 being internally threaded so as to receive wing-screw the portion ll of which is externally threaded. If, as here disclosed, the upstanding portion 30 of'the bracket 32 is provided with an aperture 42, the portion 4| of the wing-screw 40 will pass through that'aperture and bereceived in the aperture 38 in the arm 28, thus securing the device to the bracket 32. On the other hand, if it be desired to position the device on the non-apertured upstanding rim of a bucket or pail, the inward tip of the wing-screw 40 will press against the outer surface of said rim,

cause the arm 28 to be drawn against the inner surface of the rim, and thus secure the device thereto. In this way, the wiper may be positioned in close proximity to the piece of equipment which causes the operatives hands to become soiled or to any other appropriate object. At the same time, the wiper is readily detachable therefrom when it becomes necessary to dispose of the accumulated oil or grease which collects in the receptacle D.

The use and. manner of functioning of the wiper will in the main be fully apparent from the above description. Figs. 6 and '7 disclose a preferred manner of use. The operatives hand 44, palm down, may first be swept in the direction of the arrow 46, the operatives palm first passing over the wiping edge 8 on the wiper blade A and the oil or grease on the operatives palm be-. ing scraped off therefrom by the wiping edge 8 and passing down along the exterior surface of the blade A into the trough E, and from the trough through the apertures 22 in the blade A into the receptacle D, where it accumulates. As

this singlesweep of the operatives hand continues, the base of his fingers will come opposite :the wiping blade B, at which time the operative will fit his fingers into the recesses 4 and as he continues to sweep his hand in the direction of the arrow 46, the grease or oil will be wiped from the bottom andsides of his fingers 48 and will r the back of the hand is down and the hand is then swept in a single direction as indicated by the arrow 50 in Fig. 7, the direction of sweep being such that the back of the operatives hand first passes over the wiping edge II on the wiper blade C, the oil or grease on the back of the operatives hand being scraped off therefrom and passing along the'interior surface of the blade into the trough E" and thence through the aperture 24 in the blade B into the receptacle D. As this sweep is continued, the base of the operatives fingers will come opposite the wiping edge *2 of the wiper blade A and hence the back of his fingers may be scraped clean in the same 'manner as were the front of his fingers as disclosed in Fig. 6.

The above described method of use is one which has proved to be most convenient, but the wiper can, of course, be used in many other,

ways. For example, if only the blades A and B are to be used for wiping purposes, both the front and the back of the operatives hand may be scraped clean as disclosed in Fig. 6 or, if dewould pass along: the exterior of the wiperjand thus eliminate the advantages inherent in the present invention. Of course, even this limitation would be avoided if an additional trough were provided on the exterior of the blade C, but that has not beenfound necessary in most applications.

By reason of the above described construction, the wiper of the present invention may be used for a long period of'tim'e without any care or supervision, without in any way giving rise to deterioration in the conditions of cleanliness prevailing at the time and in the vicinity in which the wiper is used. The wiped oil or grease cannot drip from the wiper or fiow from'it along the bracket 32 onto themachinefl or onto the'fioor beneath. The wiper may be readily removed from the bracket 32 for cleaning purposes or for disposal of the oil or grease which has accumulated inside the receptacle D merely by removing the wing-screw 40, but this need not be done very frequently. The entire unit is very pleasing in appearance, is substantial in construction, may inits preferredform be inexpensively manufactured in a single casting operation, has -no moving parts to get out of order, and efiiciently all within the spirit of the invention as defined in the following claims.
