Application filed April 7, 1914. Serial No. 330,131.

To all whom it may; concern:

Be it known that we, WILLIAM A. AUs'rIN, residing at 415 South Cole street, and VIC- ror. J. SHEPARD, residing at 119- South Baxter street, Lima, county of Allen, and State of Ohio, both citizens of the United States, have invented certain new and useful Improvements in rHose-Strainers, fully described and represented in the following specification and the. accompanying drawings, forming a part of the same.

The present invention relates to a means of inserting a strainer in the hose-connection between an engineand tender, whereby coarse impurities may be strained from the water and the straining-plate cleaned without any delay or diliiculty whenever it becomes clogged, and without detaching any hose-joint.

The strainer is formed with a casing having two complemental chamber-sections with a strainer-plate inserted in the joint of the sections and means for clamping the sec: tions together upon the strainer which permits their ready separation when it. is desired 'to reach the strainer for cleaning the same. The strainer-casing is preferably inserted at the point wherethehose is con nected to the feed-pipe, as such pipe is fixed rigidly uponthe locomotive, and thus supports one section of the casing when the other section isfremov'ed for ole'aning,.t he

flexibility of the hose permitting such opening of the casing without detaching the hose from any of its connections. The sections of the casing are preferably made with annular flanges beveled upon their outer sides so that asplit clamp-ring with a beveled groove can be easily applied to press them together, and can be readily removed therefrom when it is necessary to open the casing, thus avoiding the use of clamping bolts which necessitate the removal ,of many nuts every time the strainer is opened.

The invention will be understood by reference to the annexed drawing, in which- Figure is a longitudinal section of the strainer, on' line '1-'-l in Fig.3, and Fig.2

is an elevation of the end for the rigid pipeconnection. Fig. 3 is a side elevation of the split-clamp, and Fig. 4 a section of the same on line H in Fig. 3. Fig. 5 is a View of a part of the strainer upon double the other figures, Fig. 6 shows the cotter in the bolt 0.

' plate 2'.

. The casing-sections a and a are made of globular form and provided with nozzles at their opposite ends, the section at having an internally threaded nozzle b for connection with a metallic pipe 0, and the section a having an externally threaded nozzle (1 for connection with a "hose-coupling h. The

nozzle b has a supporting ear or cars f at one side which can be fitted over a stationary stud to hold that section of the casing rigidly upon the locomotive, so as to resist the jars to which the casing is subject. The sections are provided with annular flanges g, g, the former having upon its inner face anannular recess 6 to receive the strainer- The recess is proportioned to set the strainer flush with the inner side of the o and nut 0' are applied, as shown in Fig. 3,

for pressing the clamp upon the strainer- "flanges. A lock nut o" is shown outside the nut 0 to hold it securely, and acotter c is shown outside of the nut 0 to prevent either of the nuts from getting loose, thus keeping The flanges are beveled upon their the device constantly in an efiicient and operative condition. A transverse notch p is -formed in the edge of the flanges g'fg, and

a studg is provided in one side of the groove 1 to engage such notch and keep the split clamp from turning around upon the flanges and holding the nut o in a prede- 'termined position for unfastening.

Fig.5 shows va strainer as a metal-plate perforated with -nu'merous small holes adapted to interceptany coarse impurities suspended in the water, and the setting of such strainer-plate in. a recess at the joint of the sections enables the packing j to tightly close the joint of the sections and the joint of the "strainer-plate therewith.

The spherical or enlarged form of the chamber-sections a, a allows an area for the openings in. the strainer-plate fullv to that of the hose or pipe With which the strainer is connected, and the means for pressing the sections of the strainer together permits their instant separation Whenever necessary for the clean ing of the strainer, and Without detaching the flexible hose pipe or metallic pipe-connections. This obviates the breaking of pipe-joints and the disturbance of pachings in union-joints either upon the strainerchanibers or elsewhere, which not only solves loss oil time but involves great Wear of the joints and pacliings; The flexibility of the hose permits the separation of the sections by merely bending the hose when the clamp 7c, 70 is removed, which is etiected by merely loosening the nut 0 upon the bolt 0, and the Whole interior or? the equal strainer may thus be cleaned WlljllOlllZ separating either of its sections from the attached pipe.

The connections provided at the ends the strainercasing furnish a, rigid support for the part a of the casing in Which the strainer-plate is jammed tightly so that it cannot become detached or lost when the strainer-sections are separated. for cleaning. The split clarnp-ring can in like manner be attached to suehstationary part, as by the chain shown at s in Fig. i, so that when loosened. from the flange of the strainer-see tions it may not be lost if inadvertently left in the roundhouse Where it would generally be taken off to clean the strainer. In such cleaning operation, the engine-man first loosens the bolt 0, and When the clamp-ring is removed from the strainer-sections it hangs upon the chains attached to the section a, and as the dirt all accumulates uponthe outer side ot the strainer-plate it can when the section a is removed, be swabbed oil Without removing it from its casing.

The provision of the lug 7 upon the section a allows the ready application of the strainer to thestationary stud upon the locomotive. The jointed clamp-ring 1; permits the rapid separation of the strainersections for cleaning the strainer-plate, and the connection of the strainer-pl-ateand the clamp-ring with the stationary section a precludes the possibility of losing either of out of service,

such parts at such times as the engine is and disconnected entirely from the tender. v it lilaving thus set forth the nature invention What is claimed herein is 2 oi the set our hands in the l. in a hose-strainer, the combination, with two hemispherical chamber-sections provided one with a screvv-connection tor a rigid iron pipe and With a supporting ear to hold such section upon the locomotive, and the other section provided with a unioncoupling for a hose, of annular flanges at the joint of the sections having their outer sides beveled as set forth, and a packing applied to such joint, a clamp having two parts hinged together and provided with a groove to engage the beveled sides of the flanges, and a pivoted bolt and not for press the clamp-parts upon the flanges, Whereby one section is held rigidly When in use, and the flexibility of the hose permits the other section to be separated theretroni for access to the interior of the coupling.

2. The combination, with two strainersections for a locomotive and tender connection, such sections having flanges at the joint, of a lug upon one ot'the sections for attachment to the locomotive thereby holding such section. rigidly, a clamp for pressing the flanges cletachahly together, and a flexible connection between the said clamp and the said rigid section, permitting the attachment and detachment ot the clamp Without risk of loss.

3. in a hose-strainer, the combination, with tWO hemispherical chambensections provided one With a screw-connection for a rigid iron pipe and with a supporting ear to hold such section upon the locomotive, and the other section provided With a union-coupling for a hose, oi annular flanges at the joint of the sections having their outer sides beveled as set forth, a packing applied to such joint, a' clamp having'tivo parts hinged together and provided with a groove to engage the beveled sides of the flanges, a pivoted bolt and nut for pressing the clamp-parts upon, the fiangeaand a flexible connection between the said clamp and the section having the supporting ear, whereby the'clainp maybe, secured on the flanges or detached, Without risk of loss.
