proved construction and capableof being more readily applied to the journal-box than is true of known devices.

The invention is illustrated in the accompanying drawings, in which Figure 1 represents a broken longitudinal sectional-view of a journal-box equipped at its. inner end with our improved dustguard; Fig. 2, a side view of the guard; Fig. 3, a sec-' tional view taken as indicated at line 3 of Fig. 4 and showing one casing-plate of the dust-guard removed; Fig. 4, a transverse vertical sectional view of the dust-guard, taken as indicated at line 4 of Fig. 6; Fig. 5, a top plan View of the dust-guard; Fig. 6, a trans- 0 verse horizontal section of the same, takenas indicated at line 6 of Fig. 3; and Fig. 7 an.

enlarged broken section illustrating the manner in which the casing-plates of the dust-Q guard are spaced and riveted. The device will be specifically and mi-' nutely described in connection with a car j our-, nal-box without intending thereby to limit; the invention unduly.

A represents an axle, B a 40 common construction,provided at its outer end with any suitable lid and at its inner end with the usual dust-guard slot or chamber 19., and G our improved dust guard secured firmly within the slot by being driven or forced thereinto. I

. 0 o are provided. The slots o are of such depth (see dotted lines, Fig. 3) and the shouljournal-box of The device 0 comprises a casing or guide formed of suitably-spaced rigidly-connected plates 0, and a spring-held sectionally-constructed automatically size-adjusting packing-ring c. The platesc are of rectangular form and fit snugly within the slot b. They are spaced and rigidly connected by rivets c shouldered as shown in Fig. 7 and have registering perforations o of ample size to receive the journal and permit transverse move- 'ment thereof (either vertically or forwardly or backwardly) with relation to itself. Asthe main play of the axle in its journal-box is ina vertical direction, the openings are elongated Vertically, as shown. The ring 0 comprises two forwardly and rearwardly swinging sections 0 0 joined together at their lower ends by a pivot o and a verticallyslidable (with relation to the other twosections) section 0 The members 0 0 have their adjacent ends reduced and rounded to form pivotal tongues o of half thickness, whereat the members are pivotally joined. Each tongue is provided with an oil-hole 0 through which a lubricant can pass to the adjacent surfaces of said tongues. The member c is provided at its ends with tenons 0 which fitfreely within mortises or slots o with which the upper 'ends' of the members ders at the'bases of the tongues sufliciently removed from the members 0 c to permit contraction of the ring, thus allowing for wear.

The ring-sections are held together,

and the ring is properly centered by opposed upper and lower springs d and opposed latrivets d and bear adjacent to their upper ends against rivets d the lower extremities of said springs bearing against the upper portions of the members c 0 From the foregoing description it will be perceived that the ring 0 collapses automatically to compensate for wear and also is movable as a whole forwardly, backwardly, upwardly, or downwardly to compensate for relative movement between the journal-box and journal. The dust-guard is applied to the journal-box by driving or forcing it into the cavity, which receives it in such manner that the casing or guide is immovably fixed in said cavity, thereby afiording smooth guide-surfaces between which the packingring moves. Preferably the heads of the rivets are allowed to project at the inner side of the casing, thereby aiding in wedging the casing firmly within the dust-guard cavity, the contact at the other side of the casing being as close as possible to prevent dust from entering there. In addition the upper end of the cavity may be closed by a dust-tight stopperf'.

It will be understood that the journal-box may be raised to permit the brass and wedge to be removed and replaced, as usual, the easing moving upwardly with the journal-box while the axle and ring remain stationary.

Changes in details and arrangement within the spirit of our invention are contemplated. For instance, the dust-guard may be inserted in its cavity the opposite end up and will give good results in this position, and the construction of the ring 0 and the arrangement of the springs may be varied, while still retaining the feature of movability in any direction in its own plane within an immovable separately-formed casing.

What we regard as new, and desire to secure by Letters Patent, is

1. The combination with a journal-box having a dust-guard cavity, of a casing comprising suitably-spaced rigidly-connected metal-" lic plates immovably secured within said cavity, and a spring-held automatically sizeadjusting packing-ring movable in any direction in its own plane within said casing, for the purpose set forth.

2. A dust-guard of the character described,

comprising a suitable casing, and a packing ring within said casing comprising two pivotaliy-counccted sections and a third section slidably jointed to the free ends of said firstnamed sections and movable with relation thereto, for the purpose set forth.

3. Adust-guard ot' the characterdescribed, comprising a suitable casing, opposed upper and lower springs supported thereon,opposed lateral springs and an automatically size-adjusting packing-ring confined between said springs and capable of movement in any di-"- rection in its own plane, for the purpose set forth.

4:. A dust-guard comprising a suitable casing, a packing-ring within said casing comprising two pivotally-connected sections and a third section having slidably-jointed connection with the free ends of said first-named sections, and opposed springs bearing upon said ring at the point of connection between said two first-named sections and at said second-named section, for the purpose set forth.

5. A dust-guard, comprising a suitable casing, a packing-ring comprising two pivotallyconnected ring-sections and a third section having slidably-jointed connection with the free ends of said first-named sections, opposed springs bearing upon said last-named ring-section and the diametrically opposite portion of said ring and lateral springs bearin g against the free end portions of said firstnamed ring-sections.

6. A dust-guard comprising two plates provided with journal-openings, rivets equipped with spacing-shoulders serving to space and rigidly connect said plates, upper and lower springs having bearings in said casing near their extremities, a packing-ring comprising two pivotally-joined sections and a third section having tongue-and-groove connection with the free extremities of said first-named sections, said third section bearing upon one of said springs, and lateral springs connected with said casing and having their extremities bearing against the free end portions of said first-named ring-sections, "for the purpose set forth.

7. The combination with ajournal-box having a dust-guard cavity, of a dust-guard casing having suitably-spaced rigidly-connected sides and immovably fixed in said cavity, and a packing-ring movable in its own plane with in said casing, and immovable laterally with relation to the casing for the purpose set forth.

8. A dust-guard comprising a suitable casing, and a packing-ring within said casing comprising two pivotally-connected sections suitably concaved to engage more than onehalf of the periphery of the journal engaged by the packing-ring, and a third section completin g the packing-ring and opposite the pivotal connection of said first-named. sections and movable toward said pivotal connection,

for the purpose set forth.

9. A dust-guard comprising a casing with suitably-spaced rigidly-connected sides, a packing-ring comprising two sections pivotally connected at their adjacent ends and suitably concaved to embrace more than onehalf of the periphery of the journal engaged by the packing-ring, and a third section having slidable connections at its extremities with g 25 the adjacent extremities of said first-named a a packing-ring moving within said casing in its own plane and immovable lateraiiy with relation to the casing, for the purpose set forth.
