UNITED 'STATE- Sv PATENT OFFICE.
JULIUS B. WANTZ, OF CHICAGO, ILLINOIS, ASSIGNOR TO VICTOR ELECTRIC COMPANY, A CORPORATION OF ILLINOIS.
EAR-Fume SPECIFICATION forming part of Letters Patent No.-'v728,526, dated May 19, 1903.
'Appiioaaon siearebmry 11,19os. semina. 142,976. .(110 model.)
To @ZZ/whom it 'may concern/:-
Be it known that I, J uL1Us B.WANT z,a citizen of the United States, residing at Chicago,
in the county of Cook and State of Illinois,
have invented a new and useful Improve,- ment in Ear-Pumps, of which the following is a specification.
My object is to provide a-particularly simple and desirable pneumatic Ypump of improved construction and capable ofready adf justment to effect Asuctionalone or suction with release` or vibrations brought about by alternate suction and compression Vor cornpression alone.`
The pumpis moreespeciallyadapted for: use with anyf suitabley tip for insertion into the ear of apatient,-when the device may be employed for exercising or massaging pneumatically the tympanum in the treatment of certain diseases of the ear.
In carrying out my invention I provide a small piston-pump fitted at; its base with a rotary slide-valve, which may be turned to and held in anyone of four positions to bring about the results above stated. In use the valve is connected to a hose (not shown) carrying a tip, earpiece, or cup for any massaging purpose.
Referring to'thefdrawings, Figure l is View of my improved pump, partly in side elevation andpartlyin section, showing the,
valve portion turned tothe position wherein it produces compression alone Fig. 2,a broken section takenonline2 in Fig. l and showing thej Ameans for adjusting the stroke of -the pump-piston Fig.V 3,' an enlarged brokense'ction of the pump, showing the valve turned@ to the suction position; Figs. 4, 5, and 6,
broken sections taken on lines 4, 5, and '6 in Figs. 1l, 7, 8, and 10, respectively; Figs. 7 and 8, plan views of the meeting faces of the valve and Valve-seat, the views being taken on dotted lines 7 and 8 in Fig. 3 and viewed as indicated by the arrows; Fig. 9,'.a broken plan section taken on line 9 in Fig. 3, the
valve being in the compression position; Figs. 10, 11, and 12, plan sectional views on line 9 in Fig. 3, but showing, respectively, the valve turned to vibration, suction and release, and suction positions; and Fig. 13, a
perspective view of one of several similar Patentedivray 1e, 1903.-?
screw-plugs inthe valve-seatportion of thel pump which confine and limit the nieve- .fining therock-shaft against4 longitudinal v play. The rear er'dof `the opening?) is closed in the present construction byan'ornamental plug e. Working in the cylinder D is a piston E on the lower vend of astem E. ing through the disk orhead C at right angles to the shaft B is an openin'gj', from which, at
one side of its axis of rotation, extends a slotV f of less width than the openingf. The head of the piston-stem forms a bearing-ring E2. A thumb-screw g, having a cylindrical shank g and a threaded shank extension g2, passes at the shank g through andformfs a bearing for thering-portion E2. Between the ring and the faceofthe face of the disk C is a washer g,5. The threadedpart g2 of the shank ypasses throughthe slot f `and carriesa nutyglin the openingf. By loosening the thumb-screwl g it and the parts-carried thereby may, be; slid toward and away .from the .center of-rotation of the disk C to diminish'or increase the throw of the pumpvpiston and V'tighten it in the adjusted position. The vlower endor head D" of the cylinder presents a fiat valve-seat or meeting face h for the meeting or seating face c' of a rotary slide-valve F. The valve Fis upon a bolt G,
having a plain shank portionlc, headlc', andthreaded end k2. The bolt passes at its shank Zt through a central opening in the valve, and the part k2 is screwed into a ythreaded socket in the head D'. Surrounding the shank lc and confined between the head k' and the under side of the valve F is a spring G', which operates to press the valve yieldingly to its seat Without interfering with its rotation.y l
Extending through the valve inthe posif tion shown is a port or passage Z, and diametrically opposite thereto is a port or passage m, extending from the face of the valve out through one side thereof and terminating in a hollow handle or projection m', adapted to fit into the end of a rubber hose. (Not shown.) Extending from the face hthrough the cylinder-head to the interior of the cylinderare passages 71,19, fr, s, and t. In the passage 'n is a chamber n', containing a ball-valve n2, seating downward. In the upper end of the said passage is a hollow screw-plug w, which limits the rise of the ball-valve, but contains slots w to prevent closing of the passage when the ball is raised against its lower end. In the passage p is a chamber 1f, containing a ball-valve p2, which seats upward, its movement away from the seat being limited by a screw-plug u, like the one described. In the passage fr is a chamber r', containing an upwardly-seating ball-valve r2, the distance of movement of said valve from its seat being limited by a screw-plug w, similar to the one described. The passages s t contain no chambers or valves.
The valve F' may be turned upon the pin or bolt G a half-revolution, this movement being limited by stops y, fastened to the head D and extending downward into the path of the projection or handle m. When turned to one stop, as shown in 3, the ports lp are brought into registeri'and also the ports m fn.. This is what is termed the suction position. Rise of the piston E sucks air through the port ym and discharges it through the port l. Thus in operation when, for example, the earpiece is inserted into the ear of the patient it tends toward producing a vacuum at the outer side ot' the ear-drum.
When the valve is turned to the reverse position, whereby the portml registers with the port p and the port l registers with the port n, the piston draws air through the port Zand forces it through the port m to exert compression against the ear-drum. When the valve is turned to the position shown in Figs. 10 and 6, the port Z is blanked and the port fm registers with the port t. In this position the piston in its downstroke forces air against the ear-drum and its upstroke withdraws the air therefrom, producing alternate compression and suction or Vibrations, as it is termed.
When the valve is turned tothe position shown in Figs. l1 and 4, the port Zregisters with the port 7' and the port m registers with the port s. \/Vhen in this position the rise of the plunger sucks air through the port m and in its descent may force the air simultaneously through the ports m l. This has the effect of producing alternate suction and release upon the tympanum.
In the head D' is the spring plunger-pin and in the face of the valve are shallow sockets z c. The plunger-pin is in the path of the said sockets and operates to engage one 'or the other when moved into register therewith. The engagement, though gentle, is sufficient to' indicate to the operator the position of the valve, but does not interfere materially with the movement of the valve from one position to another.
The rocking of the cylinder upon its bearing at d maintains it always in line with the piston-stem. The construction shown and described renders it very easy to turn the valve to any position desired quickly and accurately. The spring G' operates to hold the rotary slide-valve yieldingly against its seat, whereby under too great pressure through the passage m it will open, and thus prevent undue compression. The tension of the spring may be varied, if desired, by turning the screw G.
While I prefer to construct my ilnprovements throughout as shown and described, they may be variously modified in the matter of details of construction without departing from the spirit of my invention'as defined by the claims.
What I claim as new, and desire to secure by Letters Patent, is
l. In a pump of the character described, a cylinder having a valve-seat provided with valved ports and open ports extending to the interior of the cylinder, and a main movable valve ou said seat provided with passages adapted to register successively in the movement of the main valve with different said valve-seat ports, and operate under the action of the pump according to the relative positions of the main valve to eect compression, suction, suction and release, or vibration, substantially as described.
