Specification of Letters Patent.

Patented May 11, 1915.

Application filed March 6, 1913. Serial No. 752,415.

To all whom it may concern:

Be it known that I, WILLIAM THOMAS Mc- FARLAND, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Combined Depurators and Surgical Instruments, .of

which the following is'a specification.

My'invention relates particularly to improvements in combination interchangeable blackhead, sliver or hair, etc, removers and skin invigorators in' which the aid of vacuum is used to perform the necessary operation or to get the desired result; and the objects of my improvements are, first, to provide a vacuum pump inconrbination or in connection with the interchangeable parts or members to be described later; sec- 0nd, to provide a member or part having in combination therewith a pair of tweezers for the removal of hair or sliversor such matter with the aid of the vacuum; third, to provide a part or member for the removal or withdrawal of blackheads or similar infections from the skin with the aid of vacuum; fourth, to provide a skin or flesh invigorator, or massaging tool, which can be attached to either or both of the above stated members or parts, and used in connection with a vacuum; fifth, to provide a vacuum pump piston, which shall he slidably mounted in each, or either of the aforesaid parts or members to be described more particularly later; and sixth,- to provide a vacuum pump guide. orslide detachably secured to any of the above said members or parts. r

I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is substantially a longitudinal sectional view embodying my invention showing the pump piston pulled back to its full stroke and a pair of tweezers gripped by a pair of fingers, shown indotted lines and in the act of removing a hair or sliver from the flesh or skin. Fig; 2 is a similar view toFig. 1 embodying my invention, but partly broken away and disclosing another form used in the removing of blackheads or the like; the piston here isv shown only part way of its full stroke while being used in removing, for instance. a blackhead which (as seen) has jumped from its seat. Fig. 3

is :1 section taken on line A-A of Fig. 1.

is double ended; that IS, it has an enlarged Fig. 4 is a view in section showing a form used as a flesh or skininvigorator or mas.

saging tool and embodying my invention. Fig. 5 is a detailed view of the finger grip detached from its seat in the pump piston.

' Similar letters refer to similar parts throughout the several views. Y

In Figs. land 2 are shown two different forms or members or parts, 6 and 7 respectively, which are detachably secured to a pump piston guide (8), while in Fig. 4:, is

shown a flesh or skin invigorator or massag-" in tool (9) detachably secured to member (7%, or same could be attached in a like manner to member (6). I

Referring to Fig. 1 or Fig. 2, it will be seen that when part or member (6) or (7 either of which are interchangeable with guide (8), is attached to said guide. (8) forms a pump chamber or cylinder(6 or (7 In Fig. 1, it will be seen that the piston (10) has been drawn back to its full stroke, by pulling on the fingers (11) against the spring (12) and at the same time producing a vacuum in the chamber or piston cylinders (6 when the nose (6 is pressed against the skin or flesh of the part to be operated upon. In this instance, as

shown in ig. 1, the member (6) is formed in sucha manner as at (6 )"so as to support a pair of tweezers (13) held in a rubber cap (14) which permits of the adjustment to or from the object to be removed from the part to be operated upon (15), which in this case represents a hair (17) to be removed. The cap (14); has along bearing (16) which fits tightly over the tweezers (13) substantially making an air tight chamber when the nose (6 is premed against the flesh or skin (15). This construction also facilitates the adjustment of said tweezers (13) to the part or object to be removed. In either members (as in Figs. and 2) the operation to be performed is in full view of the operator,

because said members (6) or (7) are constructed of clear glass. In either Fig. l or Fig. 2, when the mouth or nose (6 or 7 is pressed against the flesh or skin (15) or (15 respectively, and a. vacuum obtained, pulls the skin or flesh into said noses (6 or (7 and expands-or stretches said skin causing easy access to the object to be removed (as in Fig. 1), or causes, as in Fig. 2, the object or infection or blackhead (18) actually to jump from its seat.

In Fig. 1,-it will be seen that the piston portion (10 on the opposite end of the piston (10) proper, there being a smaller'or reduced portion (10 connecting the two ends (10') and (10 The opposite end (10 of the piston 10) slidably fits in the guide (8). To facilitate assembling and economy of Construction the slide is slotted on opposite sides, as at ('8 ),to permit of inserting in the slotted hole (8 the fingers or grips (11). The grips (11) are made in two like halves and when assembled meet in the center of (10 at (19) At the extreme end of (10 is a tapped hole (20) which admits of a set screw (21) for holding grips (11) in place; there being a counter bore (22) in (10 into which the projection (11 of the grips (11) is inserted preventing, after the set screw (21) is screwed down upon the ends (11 of said grips (11), from coming out. The said grips are widened as at (11 and curved as at (11 to obtain a better purchase by fingers of the operator. Also, it

will be noted that the end (11 of the grip (11) is offset to permit being .slightly inclined so that the projected end (11 will clear the bore (22), when the screw (21) is withdrawn, on being inserted or removed from the slottedhole (8 The piston, or vacuum producing end, is composed of several parts constructed similar to an air hoist iston; there being in this case, the rod (30), the piston head (10), the leather packing or suction members (10 and the suction members retaining screw (10) which connects and holds the members (10), (10 and (10 together. This construction permits of tively.

readily when worn.

As will be seen, by referring to the several views, particularly to Fig. 1, the. parts can be readily assembled or disassembled; there being a screw cap (23) on the end (24:) of the guide (8), which acts as an abutment for the spring (12) on the opposite end of (24) of guide (8) is a threaded flange (25) to which is secured a; screw flange 26) which supports either member (6) or 7) there being two soft rubber gaskets (27) and (28) between the flange (29) of the members (6). and (7) and the screw flange (26) and the flange (25) respec- Referring again to Fig. 4, it will be note that the piston (10) is about to the end of its stroke in the member (7). It will be perceived therefore that on drawing of the piston (10) back or on the suction stroke that a vacuum is produced in the chamber (7 and within the member (9), when said member (9) is pressed, with its perforated portion (30), against a persons skin or flesh. The result thereby being that the skin will be drawn into the perforations renewing the suction member (10 (31) and on rapid stroke of the piston (10) to and fro will draw and release the skin in rapid succession, thereby massaging and invigorating the skin with beneficial results.

In Fig. 1 it will be seen that the piston (10) is actuated in one direction by the spring (12) when hand power is used, but,

however, said piston (10) may be driven mechanically.

Having thus described my invention, the merits of my improvements can be readily understood, and it will be seen that the minor details. of my construction can be altered in many ways without departing from'the spirit of my invention, but

remover member having an opposite end ,with a bearing through which may be inserted a pair of tweezers for the removal of hair, slivers, or the like with the aid of a vacuum produced by and in the self-contained vacuum pump, and an opening in' the wall opposite the one through which the tweezers are inserted.

The combination in an instrument or device of the class set forth of, a vacuum pump having a detachable cylinder and piston guide having a screw flange detachably secured to each other by a screw flange secured against the flange of the cylinder and screwed to the screw flange of said guide; said cylinder terminating at its free end in a spout or nose to which may be secured a skin or flesh invigorator; and said spout having a bearing opposite its open end in which may be inserted a pair of. tweezers for the removal of hair, slivers, or the like, with the aid of vacuum produced by and in the self-contained vacuum pump.
