Application filed November 26 1928. Serial No. 322,004.

' sition to act as a retaining means for the packing after the repacking operation has been completed.

A further object of my invention is to provide a device of the type described which is simple in construction, durable and efficient for the purpose intended.

Other objects and advantages will appear as the specification proceeds, and the novel features of my invention will be particularly pointed out in the appended claims.

My invention is illustrated in the accompanying drawings, forming a part of this application, in which Figure 1 is a longitudinal section of my device;

. V Figure 2 is a plan view of Figure 1, parts being removed, and a hinged portion being swung open;

Figure 3 is a vertical section of a body member showing the hinged portion opened;

Figure 4 is a plan view of one of the pack ing sleeves which I employ; and

Figure 5 is a side elevation of Figure 4.

While I have shown only the preferred form ofmy invention, I wish it to be understood that various changes or modifications may be made within the scope of the claims hereunto annexed without departing from the spirit of the invention. I

In carrying out my invention, I provide a central body member 1' which is threaded as at 2 into a corresponding portion 30f a supporting member 4. The member 4 may be a cylinder of a pump, or the like, in which a reciprocating rod 5 is disposed.

The interior of the body member 1 is formed with an annular recess 6 which extends longitudinally thereof, the lower portion of the recess being partially closed by an inwardly-projecting ledge 7. A removable sleeve 8 encircles the shaft 5 and is supported by the ledge 7.

lieferring now to Figures 2 and 3, it will be noted that the body portion 1 has an extension 9 which projects some distance above the surface 10 of the body member. The extension 9 is substantially semicircular in section, and is provided with a threaded portion 11, the purpose of which will be hereinafter described.

In order that a seal may be effected between the member 1 and the shaft 5 during the movement of'the latter, I have placed packing 12 in the recess 6 as will be seen by referring to Figure 1.

The conventional stu-liing box is of such construction that the operation of removing the packing therefrom is rather difficult. WVith this disadvantage in mind, I have constructed the upper portion'of the body so that approximately one-half of the side Wall thereof may be swung on a hinge so as to expose the packing.

The hinged member has been generally designated as 13. Figure 2 shows a bifurcated member 14 extending from the lower edge 15 which engages with a projection 16 of the body member. A pin 17 serves to connect the two members together. WVith such a construction, it is obvious that the member 13 may be swung from a position as shown in Figure 3 until the edges 18 of the member 13 contact with the faces 19 of the projection 9.

When the member 13 is in the position as J parent that a rotation of the cap 21 will force I if? 1 member 13 when the packing 12 is forced downwardlyby the sleeve 23. I I H From the foregoing description of the various parts of the device, the operation thereof may be readily understood. Whenever the packing 12 is to be replaced, the cap 21 is removed and the member 13 is swung access to the interior of the sleeve when the cap is removed.

5 In a stuffing box of the character described, a packing receiving sleeve having a substantially semi-cylindrical extension, a

on the pin 17 until the packing is exposed. i

The sleeve 23 may then be moved along the lengthof the shaft 5 in order to permit free access to the packing. I In carrying out the repacking operation, a supply of packing is introduced into the open end of the body memberl. The sleeve 23 is then moved axially until it contacts with the packing. The hinged member 13, when swung into the position as shown in Figure 1, is securedin place by the adjust ing cap 21, The desired amount of pressure may be exerted on the packing by rotating the adjusting cap.

I claim: I
