QPECIEICATION forming part of Letters Patent No. 352,592, dated November 16, 1886.

. Application filed May 4, 1886.

Serial No. 201,043. (Nu model.)

To all whom it may concern.-

Be it known that I, AXEL S. VOGT, of Altoona, Blair county, State of Pennsylvania, have invented a new and useful Improvement in Axle-Boxes, of which the following is a true and exact description, due reference being had to the accompanying drawings,which form a part of this specification.

My invention has especial reference to axleboxes for railway-car trucks,which it is necessary to close tightly to prevent the entrance of dust and grit, and which must also be easily opened for examination and the renewal of the oil and packing.

The object of my invention is to provide a door or lid which when closed will press firmly against its seat, and completely close the axle-box, and which when opened will remain open until forcibly closed; and it consists in the devices hereinafter fully described, and which are illustrated in what I believe to be their best form by the accompanying drawings, of which Figure l is a central sectional elevation through the axle-box and its lid; Fig. 2,a side elevation ofthe same; Fig. 3, a front view of that part of the hinge which is cast with the axle-box; Fig. 4, a perspective view of the same on the section w m of Fig. 3. Fig. 5 is a back view of the hinge put together; Figs. 6 and 7, side and front views of the compress ing-arm. Fig. 8 is a diagram illustrating the action of my device when in use.

A is the axle-box,having the rim a a around its open end made fiat and level.

13 is the hinge lug or section, secured to or cast with the box. The form and construction of this hinge lug is fully shown in Figs. 3, 4, and 5. It is perforated longitudinally for the reception of the hinge-pin, as shown in Fig. 5, and at I), Fig. 4.

In the front of the hingelug B is an open slot, b, and at the top of the slot, and near the top of the lug, is a recess, 1), (see Figs. 3 and 4,) forming abearing for the compressing-arm E, Figs. 6 and 7.

b is a projection'on the back of lug B.

G is'the lid which closes the opening in the box A. If desired, it may have a rim of soft metal cast into a recess in its fittingface which rests upon the rim a of the box.

a c are lugs perforated for the reception of c" is a curved hood which projects over the top of the hinge, covering the recess b, and terminating in a shoulder, 0 adapted to rest against the shoulder b when the lid is open.

0 is a hollow box or pocket cast in the lid 0 and open at the top.

D is a spiral spring contained in the pocket 0 The axial line of the pocket must be such as will when the lid is closed form a very obtuse angle, such as J K L, Fig. 8, with the compressing arm E, hereinafter described, which angle will have its apex pointing toward the box.

E is the compressing-arm, having at its top,

circular projecting arms 6 e, which are adapted to rest in the horizontal recess b, and at its bottom a plug, 0, adapted to enter the spring D, and a collar, 6, to rest against the end of the spring. This collar 6 should be large enough to nearly fill the opening 0 though.

capable of moving freely in it. The shaft e of the arm E is of a size whirh permits it to move freely in the slot 1)". I

F is the hinge-pin; f, an elastic washer. f is a key to retain the pin F llLPltlCB. To secure the lid to its hinge, the compressing-arm E is first placed in its hearings band the spring D is placed in its boxc The end 6 of the arm E is then inserted in the end of the spring and the lid Othen pressed upward into its proper position,whcn the perforations of the lugs B and 0 will be in line and the pin I F may then be inserted. The upper or hearing surfaceof the recess 1) should be made to project forward sufficiently to prevent the end 6 of the compressing-arm E from slipping out; but as an additional protection I provide the projecting hood 0 which will prevent the arm E from slipping out of place, and also serves as a shield to the hinge mechanism.

The operation .of my device will be readily understood, and is illustrated in the diagram, Fig. 8.

Then the lid 0 is closed, as shown in Figs. 1 and 2, the face of the lid is in the lineG H, Fig. 8, and the axial line of the arm E is represented by the line J K, while the line K L indicates the axial line or line of pressure of the spring D, the points G and J being, re-

ICO

. of the bearings upon which the arm E turns.

As will be seen, the spring D being under compression, its power is exerted in this position to keep the lid 0 tightly pressed down upon its seat, and the lid can only be opened by further compressing the spring.

G H and G H are two intermediate positions of the lid-face while being opened, the corresponding axial lines of the arm E being shown by the lines J K and J K and of the spring D by the lines K L and K L", while G H shows the face of the fully-opened lid, the arm E being then indicated by J K and the spring by K L As indicated by this diagram, the angle J K L becomes more obtuse as the lid is forced open until, after becoming a straight line, the apex of the angle reappears in the reverse direction and the force of the spring is then exerted to open the lid 0, the shoulders b and 0 serving as stops to prevent the lid from being too widely opened. The pressure of the spring D is of course sustained by the hinge-pin F, which is thus tightly clamped between the lug D and the,

lugs c c. The elastic washer f, by drawing the key f tightly against the lug 0, also aids to prevent the pin being shaken loose by the motion of the car.

While, as I have stated, I believe the construction shown and above described in detail to be the best form in which my invention can be applied, it can be varied in many particulars without departure from my invention. Thus the pocket 0 may be dispensed with and the spring secured in some other way. The spring itself need not necessarily be a spiral, for any form'of spring may be used, care being taken that it shall transmit its pressure to the lid 0 in substantially the direction shown in the drawings, and, obviously, the form of the metal compressingarm E may be changed in many Ways. The arms 6, for instance, may be dispensed with, and the arm E provided with a semi-cylindrical or spherical head, a fitting-socket being provided in its abutting place on the box in place of the horizontal socket b, and of course other stop devices may be substituted for the shoulders b and 0 nor need the abutting place be situated on the.

hinge-lug. Aseparate lug may be provided and opened substantially in the way indicated.

Having now described my invention, whatI claim as new, and desire to secure by Letters Patent, is

1. In an axle-box having a hinged lid, substantially as described, the combination of a coinpressi ng-arm journaled or pivoted on the box, with a spring abutting against the lid and transmitting its pressure thereto in one direction and through the compressing-arm to the box in the other direction, substantially- .face when it is wide open.

3. In an axle-box having a hinged lid, substantially as described, the combination of the socket b, situated on the box, the pocket 0, formed in the lid, the spiral spring D, and the compressing-arm E, pivoted at one end in the socket b, and having its other end inclosed in the pocket 0 and resting against the spring D, all substantially as and for the purpose specified.

4. In an axle-box having a hinged lid, the combination of the socket b, situated on the box, the lid 0, having a spring secured thereto, substantially as and for the purpose specified, and having a hood, 0, extending over and covering the socket b, and the compressing-arm pivoted in the socket b and bearing against the spring, all substantially as and for the purpose specified.

5. In an axle-box having a hinged lid, the combination of the hinge-lug B, havingabear' ing or socket, b, and a slot, b, extending downward from the bottom of said socket, the door or lid 0, having hingelugs c c, a box or pocket, 0?, and hood 0", extending over the open socket b, the spring D, and compressing-arm E, having arms 6 c, all substantially as and for the purpose specified.
