UNITED STATES PATENT OFFICE.
EDWARD V. HAX, OF BALTIMORE, MARYLAND.
STRAINER.
To all whom it may concern:
Be it known that I, EDlVilRD V. HAX, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented new and useful Improvements in Strainers, of which the following is a specitication.
This invention relates to strainers, and has for an object to provide a device of this character which will be particularly adapted for use in connection with faucets generally used in connection with sinks or the like and an object of my invention resides particularly in the provision of a member adapted to be attached to any well known form of faucet and secured thereto without changing the construction of said faucet or without per manently connecting any particular form of fastening means thereto.
Another object of my invention is to provide a filter consisting broadly of a member having fitted thereto a removable elastic sleeve and to provide said member with a shoulder arranged to form the double function of limiting the upward movement of the tubular member within the nozzle of the faucet and to tightly bind a portion of the elastic sleeve against the lower edge portion of the faucet so as to form a perfect water tight joint at thispoint.
Another object is to provide a device of the character set forth with means whereby water when first discharged into the device will be decreased in its volume and finally discharged from the device in a straight stream which may be ejected upon the bottom of the sink with which the faucet is connected without splashing.
Another object of the invention is to pro vide a strainer consisting of the hereinbefore described tubular member arranged to fit within a portion of the nozzle of a faucet, and to provide the said member at its lower end with an annular flange and with a shoulder disposed in spaced relation to the flange, the said shoulder being arranged to serve as a stop to limit the upward movement of the tubular member and to also serve in conjunction with the flange to secure in their operative positions a plurality of foram inous layers of material or any other suitable straining material.
Another object is to provide a strainer which when applied to the faucet will be almostinvisible and which when in its oper- Specification of Letters Patent...

to the faucet of the usual and well known hose coupling.
Other objects and advantages will be apparent as the nature of the invention is better set forth and it Wlll be understood that changes within the scope of the claims may be resorted to without departing from the spirit of the invention.
In the drawing, forming a portion of this specification and in which like numerals of reference indicate similar parts in the several views :Figure l is a vertical section taken through a portion of a faucet showing the application of my improved strainer thereto. Fig. 2 is a detail section through a slightly modified form of filter. Fig. 3 is a section taken through the elastic sleeve.
Upon reference particularly to Fi 1, it will be seen that my improved strainer consists broadly of a vertically disposed tubular body 1 formed from a single piece of metal and provided with an .inwardly flared upper portion 2. Adjacent to'the bottom or lower portion the tubular member is curved outwardly to form a flared annular passage 3 and to also form a horizontally disposed shoulder t which thus lies outwardly of the body portion and approximately at right angles thereto. The said shoulder is provided with a depending annular portion 5 which has its lower eX- tremity bent inwardly to form a horizontally disposed flange 6. The flange 6 is disposed in spaced relation to the shoulder l and between said flange and the shoulder is positioned and secured the annular edge portions of disks 7 arranged in superimposed relation as illustrated. The disks may be formed from any suitable foraminous material or from any other material adapted to act as a strainer. An elastic sleeve 8 is fitted upon the exterior surface of the body 1 and extends throughout the length of said body. Upon reference to Fig. 1 it will be seen that I have illustrated in detail the nozzle portion 9 of a faucet, the said nozzle portion having an annular exteriorly threaded surface 10 for a purpose to be presently explained. The construction of the strainer previously described is such that the body 1 is tightly held to the elastic sleeve 8 and by providing the latter it will be seen that it is also ar ranged to be secured snugly within a portion of the nozzle 9. Incident to the curvaative position will permit of the attachment i ture of the body portion adjacent to the lower end thereof it will be appreciated that the lower annular portion of the sleeve 8 when the body 1 is wedged upwardly into 3 the nozzle serves to tightly bind the lower portion of the sleeve between the lower annular edge portion of the nozzle and the shoulder 4, hence the construction provides aperfect water tight joint at this point.
hen the strainer is in its operative position shown in Fig. 1 it will be seen that the annular portion 5 disposed beneath the lower edge portion of the nozzle is located inwardly of the threads 10 to permit the usual coupling member 11 or sleeve to be engaged with said threadedportion without having to remove the strainer as will be understood. The coupling member or sleeve is of the usual form and is provided with an annular flange 12 upon which is seated a flange 13 of a hose connection 1%. Inc1- dent to the fact that I provide the body 1 with an inwardly directed flared upper portion 2 it will be seen that water while being discharged from the faucet will first come in contact with said flared portion which latter acts somewhat as an obstruction and to an extent decreases the volume of the water. Upon further movement of the water it will be apparent that upon its reaching the portion 3 of the body it becomes again greater in volume and is then free to percolate through the foraminous disks or straining material in such manner as will obviate splashing of the water when it strikes the sink of which the faucet is a part.
In Fig. 2 of the drawings the modification therein illustrated is substantially the same as that described in the preferred form, but in this instance the shoulder 15 atthe lower end of the body 16 supports an angular portion 17 upon which is formed a flange 18. The flange 18 is disposed in spaced relation to the shoulder 15 and is bent at its inner extremity to form an annular flange or shoulder 19. This construction is such that a pocket 20 is formed between the shoulder and the flange 18. the said pocket receiving the curved extremities 2 1 of foraminous disks of concavo-convex form, as shown. As stated the structure shown in the form just described is identical with the exceptions disclosed with the form described previously and a further description is therefore thought unnecessary. The device is extremely simple in construction, is composed of but few parts and may be applied to faucets of the usual form without changing them as will be understood. The device when in use effectively obviates the discharge of insects or foreign matter with the water ejected from the nozzle and downwardly should the disks of foraminous material become clogged or the device otherwise rendered inoperative incident to the collection of foreign matter or insects within the body 1. the device can be removed bodily from the nozzle 9 and inverted and the forami nous disks held close to the nozzle of the faucet. whereupon, water may be discharged from the faucet directly onto the said foraminous disks and its passage through said disks will effectively clean them. The construction of the device herein set forth is such as will enable one to polish or clean the interior of the faucet without removing the device.
1 claim 2- 1. A device of the class described comprising a member of tubular form adapted to be engaged with the nozzle of a faucet. a flange carried by the member. a shoulder carried by the member. said shoulder being disposed in spaced relation to the flange. an elastic sleeve surrounding the said member and engaged at its lower end with said shoulder and foraminous material carried by the member and confined between the flange and said shoulder respectively.
2. The combination with the nozzle of a faucet. of a strainer comprising a member of hollow tubular form having fitted thereto an elastic sleeve adapted for frictional engagement with walls of the nozzle so that the strainer will be held in its operative position, a shoulder carried by the member adapted for engagement with a. portion of the sleeve to force it into tight frictional engagement with the lower edge portion of the nozzle, and foraminous material carried by the member and disposed beneath the shoulder.
23. The combination with the nozzle of a faucet, of a strainer removably secured to the nozzle and comprising a tubular member fitted within the lower portion of the nozzle, said tubular member having an inwardly directed tapered upper portion and an outwardly curved portion adjacent to its lower end, a shoulder carried by the member and disposed beneath the lower edge of the nozzle, said shoulder having a depending annular portion disposed inwvardly of the peripheral edge portion of the nozzle, a flange carried by said portion and disks of foraminous material secured at their edges between the flange and said shoulder.
In testimony whereof I aflix my signature in presence of two witnesses.
