RETAINER PLUG Filed Nov. 9, 1934 y J/wf/vroz Patented July 2.3, 1935 v UNITED STATES 1 PATENT. OFFICE j Y, I o I Yioosgz. A Y t Y. o I RETAINEE'LG Charles E. Siegmund, Winslow, Ariz. Application November 9, 1934, serial No. 752,215
2 Claims.
My invention relates to improvements in retainer plugs for automatic air brake release or retainer valves.
It is very common today for the exhaust ports of these release Valves (and other parts of the system) which are exposed to become clogged up by dirt, moisture, insects and other foreign matter which makes the operation of the brake faulty. It is therefore the main object of my invention to provide aplug which may be used in the exhaust ports and which is so made and provided that it cannot become clogged up as set forth above and will at all times permit a clear passage or outlet for the exhaust. y
Another object is to provide a plug of this kind having a threaded mounting extension and an axially extended recess opening out at one end through this extension, the other end of the recess being closed except for an outwardly flaring passage, and a number of outwardly flaring passages being extended angularly from the recess out through the sides of the plug at spaced points.
With these and other obj ects in view the invention resides in the novel details of construction and form as hereinafter fully set forth and claimed and as shown in the accompanying drawing wherein:
Figure 1 ris an elevation of a conventional form of air brake release valve equipped with my improved retainer plug.
Figure 2 is an enlarged elevation of the plug alone.
Figure 3 is an end view of the outer` or lower end of the plug.
Y Figure 4 is a section along the line lI--lI in Figure 3.
Figure 5 is an end View of the inner or mounting end of the plus.
Referring now with more particularity to the drawing the plug designated generally at 6 includes a body 'I and a reduced and exteriorly threaded mounting extension 8 extended from one end. A recess 9 is extended axially into the body 1 through the extension 8 and'terminates short 1of the other end of the body, this closed end of the recess being cup-shaped or coned as shown at I9. Exteriorly the body 'I is round and toward its center is reduced forming an annular and peripheral shoulder or ledge Il with its at face at right angles to the axis of the plug and at the end remote from the mounting extension 8 is further reduced and rounded as at I2 forming a similar annular and peripheral shoulder or ledge I3. Y
An end passage or port Mis extended centrally or axially through the closed end of the recess 9 out through the rounded end I2 of the body and as sho-wn this passage I4 is tapered and grows larger toward its outwardly opening end. Additional passages o-r ports in two circumerentially aligned series I5 and I6 are extended angularly and radially out toward the rounded end I2 from the recess 9 through the side of the body, the rst series I5, opening at their outer ends through the ledge II and the other series I6, opening through the ledge I3. Like the end passage I4 these passages I5 and I6 are tapered and the outer ends are larger,
The plug 6 thus formed is here shown as in use upon a conventional form of air brake retainer valve A which includes an interiorly threaded exhaust port B. The plug might be mounted on this valve by screwing the threaded extension 8 directly into the port B but in this case the plug would project outward and be in the way or the hand operating the valve handle C. To prevent this, a small elbow Il is used having a short male end I8 screwed in the port B and a female end I9 receiving the extension 8 so that the plug will lie flat down along the face of the valve away from the handle as shown. Of course, in other installations and on other valves the elbow I'I might not be needed. The plug may also be used in any position and on any suitable part of the air brake system in addition to the valve here shown.
However it is mounted, the plug permits the ready exhaust of air through the passages` I4, I5 and I6 but these passages being small prevent dirt, moisture and insects from entering and stopping up the plug. Then these passages being larger at their outer ends are self cleaning as the blast of air rushes out through them. The plug 5 itself is round on its outer surface and therefore can only be installed or removed by the use of a pipe wrench thus preventingk thefts of the plug from cars or trains. It will be noted that the mouths I5a and Ilia of the passages i5 and I6 open right against the sides of the plug body I so that they will not be battered or closed by the pipe wrench as the plug is tightened or removed with the wrench.
While I have herein set forth a certain preferred embodiment of my invention, it is understood that I may vary from the same in minor structural details, so as best to construct a practical device for the purpose intended, not depart ing from the spirit of the invention and within the scope of the appended claims.
I claim:
1. In a, device of the kind described, a round elongated plug, a reduced threaded extension at one end, the said plug having a recess extended axially in through the said extension to a point adjacent the other end of the plug and having a passage extended out from the recess through that end of the plug, the plug being reduced exteriorly to form spaced annular shoulders with their flat faces at right angles to the laxis of the plug, and the plug having passages extended angularly outward :from the recess and opening through the said shoulders.
2. In a device of the kind described, a
elongated plug, a reduced threaded extension at one end, the said plug having a. recess extended axially in through the said extension to a point adjacent the other end of the plug and having a passage extended out from the recess through that end of the plug, the plug being reduced exteriorly to form spaced annular shoulders with their flatfaces at right angles to the axis of the plug, and the plug having passages extended angularly outward from the recess and opening through `,the Ysaid shoulders, the said passages being tapered and larger toward their outwardly opening ends.
