UNITED OFFIC EDMUND J. FEENY, OF MUNCIE, INDIANA, ASSIGNOR TO FEENY MANUFACTURING COMPANY, OF MUNCIE, INDIANA, A CORPORATION OF INDIANA.

PNEUMATIC-CLEANER PUMPING MECHANISM.

Specification of Letters Patent.

Patented July 25, 1916.

To all whom it may concern Be it known that I, EDMUND J. FEENY, a citizen of the United States, residing. at M uncie, in the county of Delawm'e and State of Indiana, have invented (xertain new and useful Improvements in Pneumatic-Cleaner Pumping Mechanism, of which the following is a specification.

This invention relates to cleaners, and more particularly to devices of the class known as pneumatic cleaners, such as are used for dusting and sweepin In hand operated devices of this kind it has been customary to employ constructions using bellows, single action pumps, and the like.

This invention has for its principal object to provide an improved, simple and inexpensive device of the class described, which is easily operated and which is effective and efficient in operation.

A further object is to provide a device of this character in which the members that constitute the handle are also the pump members and are relatively reoiprocable with respect to each other, and operative when so moved to draw air continuously through one opening or tube and to expel it from another.

For the attainment of these ends and the accomplishment of other new and useful objects, as will appear, this invention consists in the construction, combination and ar rangement generally shown in the accompanying drawings and described in the specification, but more particularly pointed .out in the claims.

In the accompanying drawingsFigurc 1 is an assembled view of my invention; Fig. 2 is a, longitudinal sectional view of the same, part of the handle being cut away; Fig. 3 is a cross sectional view on the line 55,'Fig. 2, parts being cut away for clearness; Fig. 4 is a cross sectional view on the line 6-6 Fig. 1; Fig. 5 is a longitudinal sectional "low of the preferred embodiment of my invention; Fig. 6 is a plan view of one of the members which constitute the valve openings. Fig. 7 is a view on line 15--15 of Fig. 5.

Referring now more particularly to Figs. 1 and 2 of the drawings, a base member 10 is provided with a hinged bottom member 11 formed with an opening 12 from which there extends upwardly a guide 13. This hinged member is secured to the base in any desired or suitable manner, and packing matcrial ll is inserted between it and the base to make an air tight connection. In this form of the invention locking devices 15 are shown which are adapted to retain the hinged member and the packing in position. The 0pcning 12 of the hinged member is preferably disposed adj accnt the front of the IOCQPtALClO. l0. and a bearing surface 16 is provided adjacent the rear thereof to form. in conncction with side members 1.7, three points which determine the plane in which the opening 12 is located. In the top of the receptacle 10 there is formed a depression 18 which is provided with an aperture 15), and cxtending from the guide. 13 is a ballle plate 20, preferably formed of reticulated material which extends over the opening 19. Seated in the depression 18 is a swivel or hinge member 21, which is preferably T- shaped, and is provided with an opening 22, the stem of the member 21 being curved to form a handle connecting portion 23. This hinge member 21 is secured to the receptacle 10 by means of a plate 24- which is formed with rounded end portions 25, and a central aperture to permit the rotation of the hinge member in the depression, the opening 22 in the said hinge member being adapted to register with the aperture 19 in the depressed portion 18, regardless of the rotated position of the hinge member. The rotation of the hinge member is of course limited to a certain degree.

A funnel shaped receiver 26 is adapted to make connection with the handle shapc l connection 23 of the hinge mcialier 21, and this receiver is provided at its enlarged end with a threaded portion 27. In this receptacle there is inserted a cone-shaped partition 28 which is preferably formed with a cone of reticulated material 29 over which a partition 30 of material permeable to air and not permeable to dust, is positioned. These cone shaped portions 29 and 30 are secured by suitable means to a grooi'ed ring 31. the groove being adapted to seat a ring member 32 which secures the cone shaped partition and the screen of reticulated material to the ring 31. This entire cone-shaped partition is adapted to be inserted in the receiver 26 and to be held in such position by a threaded member 33 which is screwed ice into the end of the receiver and which clamps the packing 34 in position between it and the threaded member 27.

The pump which is employed in this exemplification of my invention is composed of a cylindrical member 35 and a piston 36, movable therein, the latter being provided with tubular piston members 37 and 38, secured to the opposite sides of the piston, and extending through the ends of the cylindrical member 35. Suitable packing members are provided between the cylinder and the piston tubes comprising in the present exemplification internal threaded mem-' bers 39 secured to the cylinder and external threaded members 40 surrounding the tubes 37, 38 and adapted to be screwed in the threaded members 39, and to clamp the packing 41 against the tubes to prevent the escape of fluid. One of the piston tubes, as 38, is connected to the threaded member 33 extending through a partition 42 and having communication with the interior of the c0ne-shaped partition 28 when the latter is in position in the receiver 26. The other piston tube 37 extends through the other end of the cylinder 35 and is preferably provided at its outer end with a nozzle 43, which is adapted also to provide a handle for holding the said device. The cylinder 35 is also provided with a handle 44 and the piston and the cylinder being movable relatively with respect to each other, it will be seen that the cylinder may be moved up and down while the piston remains stationary, or the cylinder may be held stationary while the piston is moved relatively thereto. The piston 36 is freely movable in the cylinder and is formed with a peripheral groove 45 in which a packing ring 46 is adapted to be seated. This packing ring bears against the inner surface of the cylinder 35 and against either flange of the groove 45, but is not wide enough to entirely fill the groove. This packing ring 46 may be of any desired or suitable material and in the present embodiment is preferably formed of an elastic or flexible material such as sponge rubber,-

or the like. Extending from the-end of the .piston tube 38 and communicating therewith are passages 47 which communicate also with passages 48 extendingthrough the iston. Extending from the end 0 the ot er tube 37 and communicating therewith are passages 49, which communicate with the groove 45 in the eriphery of the piston.

Arranged on t e sides of the piston are flexible valve members 50 and 51, which are adapted to cover and uncover the. passages 48 which extend throu h the piston. These members are operated y the pressure which is exerted upon them by t e passa ea gof fluid. It will be seen by reference to 2 that communication is afiorded between one cylindrical chamber, as a, around the flange in the small end of the receiver.

of the piston and under the packing ring through the grooves 45 and passages 49, to the piston tube 37 when the packing ring is in the position shown and when the direction of motion of the piston with respect to the cylinder is the same as that shown by the arrow within the cylinder. At the same time communication is afforded between the piston tube 38 and the cylndrical chamber Z) on the other side of the piston by means of the passages 47 and 48, the valve member 51 being raised by the pressure of the incoming fluid and the valve member 50 being in the position to close the passage 48 from the chamber a by reason of the pressure of the fluid in this chamber. Thus it will be seen that fluid is drawn through the piston tube 38 into the chamber 1) and is expelled from the chamber a into the piston 37. When the relative direction of movement between the cylinder 35 and the ,piston 36 is changed, the packing ring 46 will be moved in contact with the other flange of the groove 45 and communication will be afforded between the piston tube 38 and the cylindrical chamber a through the passages 47, 48 and the cylindrical chamber 6 will have connection by way of passages 49 with the piston tube 37 Thus it is seen that the piston tube 38 is the suction tube and the piston tube 37 the discharge tube, regardless of the direction of movement of the cylinder and piston with respect to each other.

In operating this cleaner it will be seen that the receptacle 10 is allowed by the hinged connection to lie flat on a plane surface regardless of the angle of inclination of the handle with respect thereto.

The peculiar construction of the piston and cylinder is such that the piston is freely rotatable with respect to the cylinder, so that the action of the pump is not impaired by the relative rotation of the said parts. Since the filtering partition is inserted between the inlet opening and the pump, it is evident that the air which is drawn into the pump is freed of all dirt orother impurities, and that the blast of air is expelled from the nozzle, which may be used to blow dirt from the crevices or other inaccessible parts. I

The object of the baflie partition 20 is to prevent large )articles of dirt or foreign matter from hinged connection mto the receiver '26, the base 10 being adapted to receive such particles.

The receiver 26' may be removed from the handle portion of the hinged member 21 and the whole base portion dispensed with, and another receiving inlet may be inserted It is also evident that the receiver may be removed from its connection with the tube 38 and the eing sucked through the' pump may be-operated separately. The partition in the receiver 26 is readily removable for cleaning or other purposes. The form of partition shown is preferable for the reason that it presents a large sifting area for the dirt and air, the reticulated partition 29 serving to hold the outer partition 30 in distended position. The threaded member 33 when inserted in the end of the receptacle 26 is adapted to position. the partition 28 centrally with respect to the receptacle 26.

The preferred construction, combination and arrangement of the several parts which constitute my invention are shown in Fig. 5, with detailed views of the parts shown in Figs. 6 and 7. This preferred embodiment of the invention differs from the one previously described in the form and construction of the base and hinge members, the dust receptacle and the dust partition, and the piston and valve members.

Base member 10 is formed with symmetrically extending side members each having a bottom opening 12', and these have communication through the body of the base portion and through the swivel hinge member 21 which is formed and attached in a manner similar to hinge member 21'. The stem of the hinge member .21 is slit and formed with lugs 58 which are pressed together by suitable means to secure the stem of the hinge member to a tube.

The dust receiver 26' is preferably formed with one portion cylindrical and the other tapered. A tube 59 is positioned in the ta pered end of the receiver, extending without the receiver to provide a connecting end for the stem of the hinged member 21', and the inner end is provided with a deflector plate 60 to deflect the particles of dust and dirt as they are drawn into the receiver. In the receiver 26' is placed the dust partition 28', which comprises a shell 61 of reticulated material covered on the outside with a partition 62 of material permeable to air and not permeable to dust or dirt. This partition 62 is substantially conical in shape, the smaller end being disposed Within the shell and havin pull string 63 attached to the tip thereo to draw it out of the shell when the dust partition 28 is removed. This construction presents a large area of filtering surface for the displacement of the liltering members.

A cover plate 64 for the receiver 26' is preferably threaded on the end of the tube 38 having thumb screws 65 to secure the cover plate 64 and the receiver 26' together and to clamp the end of the dust partition 28' therebetween to hold the latter in position.

At the ends of the cylinder are cap members 39' and threaded members 40' surrounding the tubes 37, 38 and coiiperating therewith to provide a packing joint.

Threaded on the adjacent ends of the tubes 37, 38 and suitably secured together are the valve members 66 and 67. These valve members form a peripheral groove 45', which is adapted to receive the packing ring 46, the diameter of the flanges which constitute the groove being less than the inside diameter of the cylinder. Valve member 66 (see Fig. 7) is formed with perforated projections 67 some of them rovided' with fastening lugs 68, two of whlch are slotted to receive a shield 69. The object of this shield is to prevent the rushing of air from all sides, as this has been found, in practice, to produce a whistling sound. As the tube 37 has connection with the center of the member 66, the air passes from the groove 45' between the projections 67 to the tube 37. Valve member 67 is hollow, with openings 70 in the sides thereof, one set of which register with the perforations in the projections 67, the tub 38 communicating with the interior of the member. The flexible valve members 50 and 51 perform the same function as in the previously described embodiment of the inventi'on.

Although the valve members 66 and 67 may be composed of any desired and suitable material, the form just described is more particularly adapted to be made of metal. As the operation of this latter embodiment of the invention is similar to the operation of the previously described form, a second detailed descriptionis not deemed necessary.

The construction of the pump is such that it may be used for pumping any kind of fluid, either liquids or gases, but it is especially adapted for use in connection with pneumatic devices. By reason of this construction the cylinder and piston may be moved relatively to each other to simulate a sweeping movement, and it will be noticed in this connection that in the present embodiment this movement is similar to that employed in using a broom or a carpet sweeper of the rotating brush type; the receiver may be kept stationarv and the suction continued by moving the cylinder. up and down with respect to the piston, or the cylinder may be held rigid, and the piston and receiver may be moved relatively thereto. In either case the action is the same and as long as the one is moved relatively to the other, the air will be drawn in through the tube 38 and expelled from the discharge tube 37.

It is evident changes in the construction, combination and arrangement of the several parts of my invention, without departing from the spirit and scope thereof.
