STRAINER AND DIRT COLLECTOR Filed Oct. 6, 1927 Patented May 21, 1929.
UNITED STATES MILO DENNEY, OF TIPTON, MICHIGAN.
S TRAINER AND DIRT COLLECTOR.
Application filed October 6, 1927. SerialNo. 224,473.
This invention relates to strainers and dirt collectors of the style set forth in my Patent No. 1,632,699 granted June 14, 1927, and 1t is an object of the invention to provide a device of this kind comprising means to effectively retain separated dirt or the like within the bowl upon creation of back suction as may occur when the device is employed in connection with a railway air brake system and the like.
It is also anobject of the invention to provide a device of this kind comprising a collecting bowl into which a straining element extends together with means for pro- 1 tecting such element.
The invention consists in the details of construction and in the combination and ar rangement of the several parts of my improved strainer and dirt collector whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth. l
The novel features of my invention will hereinafter be definitely claimed.
In order that my invention may be the better understood, 1 will now proceed to de scribe the same with reference'to the ac-v companying drawing, wherein Figure 1 is a sectional view illustrating a strainer and dirt collector constructed in accordance with an embodiment of my invention; I
Figure 2 is a sectional view taken substantially on the line 22 of Figure 1; I
Figure 3 is a View in top plan of the valve member as herein set forth.
As disclosed in the accompanying drawing, B denotes a body, preferably cast, and substantially T-shaped in elevation and which is provided with two boresor passageways 1 each leading from an end of the head portion 2 of the body and terminating at the lower end of the stem portion 3. The outer portions of the bores or passageways 1 are provided with means, such as internal threads 4, whereby the device in its entirety may be readily interposed within a desired line.
Underlying the stem portion 3 of the body B is a cup member or bowl C, the upper portion of which being partially closed by a plate 5 which provides a relatively large opening 6 with which the inlet bore or passageway 1 communicates.- The free edge of the plate 5 is straight and extending downwardly from said straight edge portion of the plate 5 and inclined in a direction to partially underlie the opening 6 is a plate or flange 7. This plate or flange 7 serves particularly to provide protection for the straining element 8 which extends within the bowl or cup member C through the opening 9 in the plate 5, said opening 9 registering with the outlet bore or passageway 1 of the body.
Carried by the side wall of the cup member or bowl C and extending entirely therearound is a continuous plate 10 arranged in the formof an inverted cone having its lower or apex portion open, as at 11, the marginal portion of the plate defining such opening being ground to provide a downwardly member 18 positioned above and spaced from' a second member 19 substantially in the form of an inverted cone with its lower or apex port-ion open, as at 20. These members 18 and 19 are secured one to the other and main tained in desired relation through the instrumentality of the interposed arms 21. Normally the valve structure is in its open position with the central or apex portion of the member 18 resting upon the upper end of the stem 17. However, upon abnormal suction within the bowl, especially in connection with an air brake system orv the like, the valve structure will move upwardly bringing the member 18 in contact with the valve seat 12, thus effectively preventingthe dirt or the like collected within the cup member or bowl C being carried out.
As the fluid passes into the cup member or' bowl C from the intake bore orvpassageway 1 contact ofthe same with the continuous plate 10 will resultin a portion of the dirt or foreign matter carried by. the fluid being drawn through the opening 11 into the lower portion of the cup member or bowl C. The fluid as it passes out through the outlet bore or passageway 1 first passes through the straining element 8 which is oi a character to substantially entirely remove from the fluid all remaining dirt or foreign matter. This dirt or foreign matter separated from the fluid drops through the opening 11 upon the upper plate 18 of the valve structure V and from said plate 18 upon the lower plate 19 and will readily drop out through the lower central opening 20 of such plate.
This lower plate 19 comprised in the valve structure V operates to catch the dirt which is within the lower portion of the cup member or bowl C when the air brake is set in emergcncy as it will serve to keep such dirt from readily passing up over the upper plate 18. This desirable action is further facilitated in view of the fact that the lower peripheral edge of the upper plate or member 18 is substantially midway of the upper and lower edges of the lower plate or member 19.
It is also to be 'barticularly noted that the plate or flange 7, operates to prevent the dirt passing into the cup member or bowl C from coming into direetcontact with the straining element 8.
The cup member or bowl C is adapted to be secured to the stem 3 of the body B in any desired manner and herein disclosed through the instrumentality of the bolts 22.
From the foregoing description it is thought to be obvious that a strainer and dirt collector constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my in vention is susceptible of some change and modification without departing from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.
