Patented Dec. 23, 1941 UNITED STATES PATENT OFFICE BLACKHEAD EXTRACTOR Frank W. Benton, Wilson, N. C.
Application September 18, 1940, SerialNo. 357,307
2 Claims.
This invention relates to a device for extracting comedones, or what are commonly known as blackheads, from the skin, and the main object of the invention is to provide a simple, inexpensive and eflicient construction of device by which blackheads may be easily, quickly and painlessly extracted. 6
A further object of the invention is to provide a device of this character which may be readily manipulated for extraction of blackheads without injury to the skin and which is so constructed as to be easily kept in sanitary condition.
The invention consists of the features of construction, combination and arrangement of parts, hereinafter fully described and claimed, reference being had to the accompanying drawing, in which:
Fig. l is a view in side elevation of a blackhead extractor constructed in accordance with my invention.
Fig. 2 is a vertical longitudinal section on line 22 of Fig. 1 showing the parts as they appear in their normal position.
Fig. 3 is a transverse section on line 33 of Fig. 2.
Fig. 4 is a transverse section on line 4-4 of Fig. 2.
Figs. 5 and 6 are views similar to Fig. 2 showing, respectively, an adjustment of the plunger for a cleaning operation and an adjustment of the plunger for a blackhead extracting operation.
Fig. 7 is a plan view of the cylinder member of the extractor.
In carrying my invention into practice I provide an extractor of the character described comprising a body or cylinder formed of a body or cylinder member proper I and a cap member 2. The member I is provided at its forward end with a reduced portion forming an extracting tube 3 which is in open communication at its rear end with the cylinder chamber 4. In rear of this cylinder chamber 4 the member I is provided with a slot 5 extending diametrically through the same from side to side thereof, and at its rear end the member I is provided with and terminates in an externally threaded tubular boss or nipple 6.
The cap member 2 is provided with a cylindrical forward portion which is of the same external diameter as the body of the cylinder member I. This portion of the member 2 is formed with an internally threaded opening I to receive and engage the nipple, whereby the cylinder and cap members are detachably connected. In rear of this opening I and communicating therewith is a socket 8, also located in the cylindrical part of the cap member. The rear end of the cap member is reduced and terminates in a knob or enlargement 9, whereby it may be conveniently gripped and manipulated.
Mounted to slide in the cylinder member is a plunger comprising a plunger body I0, which fits and slides in the chamber 4 and a reduced plunger portion orstem I I which is fitted to slide in the bore of the tube 3. A coiled spring I2 is disposed in the forward portion of the chamber 4 between the plunger body I0 and the front wall of said chamber and acts to hold the plunger normally retracted. Another spring I3 is arranged to bear at its forward end against the rear end of the plunger body and extends from the cylinder member I through the nipple 6 into the socket 8 of the member 2 and operates to hold the plunger pressed forwardly and to resist its rearward movement except to a predetermined degree under the action of the spring I2. The two springs operate in balancing relation to normally hold the plunger in the position shown in Fig. 2, in which the forward end of the plunger stem I I lies within and a short distance inwardly from the forward end of the tube 3, in which position such end of the plunger stem is enclosed and protected from injury or contamination by contact with extraneous objects.
Fitted to slide upon the cylinder is a sleeve I4 which is normally disposed in the position shown in Fig. 2 and covers the slot 5. This sleeve is provided with an annular bead or enlargement I5 which is preferably milled or serrated and forms a finger-piece by means of which it may be moved longitudinally relative to the cylinder. This sleeve is held in position and connected with the plunger by means of a coupling pin I6 which passes through an opening in the plunger body and through the slot 5 and is movable backwardly and forwardly in the latter. Any ordinary type of coupling pin may be used which is engaged at its opposite ends with the sleeve in any suitable manner, but in the present instance I have shown the use of a screw having a threaded end engaging the sleeve at one side and a headed end countersunk in the sleeve at the opposite side. The use of a coupling screw is preferred as it provides for the more ready and convenient coupling of the parts together and release of the sleeve and plunger by disengaging the screw in order to adapt the parts to be readily and conveniently assembled for use or disassembled for cleaning, repairs or other purposes.
The normal position of the parts, as stated, is
that shown in Fig. 2, in which the plunger is in retracted position and with the forward end of the plunger stem lying within the tube 3. This normal arrangement of the parts adapts the plunger to be moved forwardly to project the plunger end, as shown in Fig. 5, for cleaning by simply moving the sliding sleeve forwardly or holding said sleeve stationary and exerting rearward pressure on the knob 9 of the stem member 2. This operation of projecting the plunger will clear the forward .end of the tube 3 ofany foreign substances which may have accumulated therein and will expose the end of the plunger stem so that it may be cleaned before use and at other times to maintain it in a sanitary condition. Upon the release of the parts after such forward adjustment of the plunger the parts will be returned to normal position by the springs l2 and I3. In the use of the device for the extraction of a blackhead, the plunger may first be projected, as shown in Fig. 5, and cleaned preparatory to the extracting operation. The extractor .is then disposedso as to bring the forward end of the tube 3 over the blackhead and in contact with the skin about the same, whereupon the sliding sleeve is moved rearwardly to impart corresponding motion to the plunger, which will be adjusted to the position shown in Fig. 6. In this will be readilyunderstood without a further and extended description, and it will be seen that the invention provides a device for the purpose which is simple of construction, eificient in action for the extraction of blackheads without injury to the skin, and which may be manufactured and sold at a comparatively low cost. While the structure disclosed is preferred it will, of course, be understood that changes in the construction, form and arrangement of the parts may be made within the scopeof the appended claims without departing from the spirit or sacrificing any of the advantages of the invention.
What I claim is:
1. 'A device for extracting blackheads from the skin comprising a cylinder having a suction tube at one end thereof, a plunger movable in said tube, said plunger having an outer end portion normally lying a distance inwardly from the outer end of the tube and said plunger being movable forwardly to project its end beyond the outer'end of the tube and being movable rearwardly to form a vacuum in the tube, and spring means for maintaining the plunger in its normal position and retracting it after being projected forwardly.
2. A device for extracting blackheads from the skin comprising a cylinder having a suction tube at one end thereof, a plunger movable in said tube, said plunger having an outer end portion normally lying a distance inwardly from the outer end of the tube and said plunger being movable forwardly to project its end beyond the outer end of the tube and being movable rearwardly to form a vacuum in the tube, a spring in the cylinder between the cylinder and plunger when moved backwardly to normal position, a spring in the cylinder between the cylinder and plunger for returning the plunger when projected forwardly back to normal position, and means for moving the plunger forwardly or backwardly.
