Oct. 17, 1933. J. A. PILCHER RAILWAY JOURNAL BOX- Filed Jan. 14, 1931 INVENTORQ Patented Oct. 17, 1933 UNITED STATES RAILWAY JOURNAL BOX John A. Pilcher, Roanoke, Va., assignor to Western Railway Equipment Company, St. Louis, Mo., a corporation of Missouri Application January 14,

6 Claims.

My invention relates to an addition in the way of an improvement in the ordinary well recognized journal or oil box for railway cars, or

I vehicles, for the purpose of preventing the waste, which with the oil fills the lower portion of the box, from coming in contact with the lower portion of the bearing or brass on the line where it terminates adjacent the journal, and under certain conditions of car impact or the operation of brakes, while the car is in motion allows an opening between the journal and its bearing for the waste to insert itself. When the waste enters this opening it is often caught and causes a hot box.

In the drawing, Figure 1 represents a vertical, longitudinal section through the journal box on the line of the axis of the axle.

Figure 2 is a half transverse section through the line XX of Figure l, and shows the same form of the waste grab preventer 6, as is shown in Figure 1.

Figure 3 is a half transverse section through a journal box, similar to Figure 1, which shows a different form of waste grab preventer 6, which is hinged to work down instead of up, as in Figure 2.

Figure 4 is an enlarged partial section of the journal box shown in Figure 2, and shows the waste grab preventer 6, raised to its highest position where it is out of the way ,when the end of the axle with its journal and collar is thrust into the inner end of the journal box.

Figure 5 is an enlarged partial section of the journal box showing the same form of waste grab preventer 6', as shown in Fig. 3, depressed to its lowest position so as to be out of the way of the end oi the axle with its journal and collar when they are thrust into the inner end of the journal box.

The numbers referring to the parts in the various figures and views represent the same parts.

The number 1 is the journal box. 2 is the journal bearing. 3 is the journal box wedge. 4 is the journal shown by dot-and-dash lines in Figure 1, and in normal position by full lines in Figures 2, 3, 4 and 5. This same journal is marked 4' in abnormal positions in Figures 2 and 3, and shown in dot-and-dash lines. 5 is the part of the axle just inside of and-adjacent the journal 4, and which normally enters the inside end of the journal box through the dust guard '7. The dust guard 7 fits snugly the portion of the axle 5, and floats in the dust guard pocket 8, with any movement of the axle other than in the 1931. Serial No. 508,606

(01. s0s-s9) A direction of its axis. There is sufficient room around the outside periphery of the dust guard and the inside periphery of its pocket to allow this movement. The dust guard pocket 8, has an outerwall 9, at the inner end ofthe journal box 1, and an inner wall 10, on the opposite side of the dust guard holding it in proper place as it moves with the axle. The inner periphery of theopening through the dust guard pocket wall 9, is shown by the dotted line 12, in Figures 2, 3, 4 and 5. The inner periphery of the opening through the dust guard pocket wall 10, is shown by the full line 11, in Figures 2, 3, 4 and 5. l I

The periphery of the portion-of the axle; at 5, Figure 1, is shownby the lines '13 in Figures 2, 3, 4 and 5 and is shown well outside of the journal line 4, and well inside of the

lines

11 and 12, marking the periphery of the openings through dust guard pocket walls adjacent the portion of the axle5, where it passes through the dust guard '7, and its walls 9 andlO.

This description of the normal relation of parts with the drawings represent the well known and much used railway journal box. The forms of the periphery of the openings in the dust guard Walls may beof other forms than shown.

By observation of operation and special experiments, it has been shown that with the impact of cars, one against the other, the inertia of the axle and the wheels mounted on same, forces the journal 4 out of the seat in its bearing 2, and momentarily it takes the position 4', Figures 2 and 3, relative to the bearing 2. This lateral movement of thejournal to its bearing is limited by the distance between the periphery of the axle, shown by the line 13, and the inner periphery of the dust

guard pocket wall

11 or 12.

A similar movement of the journal 4, relative to its bearing 2, takes place with certain braking conditions, such as the hard application of the brakes on the car while the car is moving, or a combined application of the power and hand brakes, even with the car standing, and when there are no inertia forces to assist in the displacement. This .relative displacement of the journal in the seat of its bearing, along with the inertia forces allows the waste, with which the bottom portion of the journal box is filled, to insert itself between the journal and its bearing. The reseating of the journal on its bearing often catches the waste and is called a waste grab. These waste grabs very often result in the journal running hot. It is very desirable that the waste should be kept away from the bottom of the bearing where it is adjacent the journal so there will be no chance for the waste grab. The application of the waste grab preventer 6, or 6', will keep the waste normally in the bottom portion of the journal box 1, from reaching the bottom portion of the bearing 2, under the most adverse conditions of service, and at the same time will not prevent the oil soaked waste from bearing against the bottom portion of the journal 4, and properly lubricating same.

The

waste grab preventers

6 or 6 are hinged to supports 14 or 14', in such manner that they are free to follow the lateral movement of the journal when it is displaced in its seat in its bearing without offering resistance to said movement that is harmful to either the waste grab preventer 6, or the journal 4.

Figure 5 shows the support 14 attached to the journal box 1. Figures 2, 3 and 4 show the supports 14, made in the form of a frame supporting the

Waste grab preventer

6 or 6, one on each side of the journal 4, made so they can be assembled outside of the journal box along with the waste grab preventer and by proper manipulation and springing be inserted in the box before the journal or its bearing is inserted.

The

waste grab preventer

6 or 6 is held to the

supports

14 or 14 by a pin 15. There is wound around this hinge pin 15, springs 16, having projecting ends, one end reacting against the side of the box 1, and the other end bearing against the waste grab preventer 6, to keep it against the journal 4, in all its harmful movements relative to its seat on its bearing 2. The waste grab preventer 6, is made so it approaches the length of the journal 4, but enough shorter so that with the normal movement of the axle, in the direction of its axis, relative to the journal box, it will not be caught and injured between the axle collar 17, and the inside dust guard pocket wall 10. The hinge parts of the waste grab preventer 6, opened to receive the hinge part of the supports 14, are made wide enough for the supports 14, the springs 16, and an additional amount that will allow the waste grab preventer to move with the journal and its axle in the direction of the axis of the axle, without binding the axle collar 17, and the supports 14, or between the shoulder formed by the portion of the axle 5, at its junction with the journal 4, and the waste grab preventer supports 14.

' The waste grab preventer 6, is provided with an extended portion 18, which when the waste grab preventer is forced against the sides of the box so as to be out of the way of the entering axle with its collar, it will be held in this position, shown in Figures 4 and 5, by the spring in the supports 14, even against lighter forces of the springs 16, assisted by gravity. In the normal position of the waste grab preventer 6', the projection 18, will be free from the sides of the box and the springs 16 will make the edge of the waste grab preventer follow any abnormal lateral movement of the journal on its bearing and keep the bottom or waste holding portion of the journal box cut off from the top or bearing portion of the journal box.

The side of the waste grab preventer 6, coming next the waste, has placed on it prick punches or snags 19, turned in such direction that the rising waste if it is forced hard enough to lift the waste grab preventer against the action of the springs 16, will catch on the snags or prick punch projections. It will thus be prevented from easily reaching the bearing and will help hold the waste grab preventer to the abnormal lateral movement of the journal on its bearing.

The method of placing the waste grab preventer, with the journal box, axle, bearing, wedge and waste, in service for its proper functioning is as follows:

The waste grab preventer, with its supporting rame, is put through one of the end openings in the journal box. It is then forced to the position up or down, as the case may be, shown in Figure 4 or 5. In this position the end of the axle with its journal and collar can be inserted in the journal box and the bearing and wedge can be put in place in the usual manner.

7 After this the waste grab preventer can be' forced againstthe action of its spring supports,

away from the sides of the box. When so released the springs 16 will cause it to bear with its edge with a harmless pressure against the periphery of the journal and wipe it free of all waste and lint as the journal turns. The bottom portion of the journal box is then packed with oily waste in the usual manner and all is ready for service. It is readily seen that the free movement of the edge of the waste grab preventer and the location of this edge relative to its hinge point will prevent its being caught and damaged by any movement of the axle in the box.

Having thus described my invention, I claim the following:

1. In a device of the class described, the combination with a journal box and axle, of a brass in said box and bearing on the upper part of the axle, the lower part of the box forming a chamber containing oil retaining packing, and a pair of packing guards positioned one at either side of the axle and extending between the axle and the adjacent wall of the box to prevent access of packing to the brass, said guards yielding laterally to compensate for the relative lateral movement of the axle approximately into contact with the box wall.

2. In a device of the class described, the combination with a journal box and axle, of a brass in said box and bearing on the upper part of the axle, the lower part of the box forming a chamber containing oil retaining packing, and a pair of packing guards positioned one at either side of the axle between it and the box and separating the packing in said chamber from the brass, said guardsbeing extensible'and retractible in a lateral direction to maintain contact with both the axle and the box in any operative position the parts may assume.

3. In a device of the class described, the combination with a journal box and axle, of a brass in said box and bearing on the upper part of the axle, the lower part of the box forming a chamber containing oil retaining packing, and a guard plate positioned between one side of the axle and the adjacent box wall, said plate being pivoted adjacent the side of the axle and capable of swinging on its pivot to maintain contact with the other part during its relative movement toward and away from said first named part.

4. In a device of the class described, the combination with a journal box and axle, of a brass in said box'and bearing on the upper part of the axle, the lower part of the box forming a chamber containing oil retaining packing, and a guard plate positioned between one side of the axle and the adjacent box wall, said plate being pivoted adjacent the box wall and swinging on its pivot to maintain contact with the axle during the 6. In a device of the class described, the combination with ajournal box and axle, of a packing guard positioned at one side of the axle and pivoted to swing toward the axle, and a projection carried by the guard and adapted to have frictional contact with the box to retain the guard in retracted position to permit of the insertion of the axle in the box.
