TRUCK.

SPECIFICATION forming part of Letters Patent No. 770,527, dated September 20, 1904.

Application filed December 18, 1903. Serial No. 185,733. (No model.) I

To all whom, it may concern:

Be it known that 1, JOHN E. KELLY, a citizen of the United States of America, residing at Allegheny, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Trucks, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in trucks, and relates more particularly to warehouse-trucks and the like.

Myinvention has for its object the provision of novel means for swiveling the wheels upon the body of the truck, of novel means for journaling the wheels in the swiveling attacl ment, and of novel means for preventing spreading of the journal-bearings.

My invention also has for its object the con struction of a truck that will be extremely simple, strong, durable, comparatively inexpensive to manufacture, and highly efficient in its use.

With the above and other objects in view the invention consists in the novel construction, combination, and arrangement of parts, to .be hereinafter more fully described, and specifically pointed out in the claims.

In describing the invention in detail reference is had to the accompanying drawings, formingapart of this application, and wherein like numerals of reference indicate like parts throughout the several views, in which- Figure 1 is a side elevation, partly in vertical section, of the swivel and bearings. Fig. 2 is a front elevation partly in vertical section. Fig. 3 is a detail vertical sectional view of the journal-box. Fig. 4 is a side elevation thereof. Fig. 5 is an under side plan view of the plate, which is rigidly secured to the under face of the truck. Fig. 6 is a perspective view, partly broken away, of the lower portion of the journal-box. Fig. 7 is a detail view in detail of portion of the spring-bolt extending through the journalbox. Fig. 8 is a detail view of a modified form thereof. Fig. 9 is a vertical fragmentary view of the hub of the wheel. Fig. 10

shows a portion of the journal bearings 5 formed in two sections. Fig. 11 is a perspective view of a truck, showing my improvements applied thereto.

In the drawings, 1 indicates the platform of the truck, to which is rigidly secured upon its under face a plate 2, this plate being secured by means of bolts 3 and integral barbs or prongs 4:, which extend into the under face of the platform. This plate 2 has formed centrally therein a depression 5 and has also formed on its under face an annular guideway 6. An axle-bearing7 carries a disk 8, having an annular flange 9, adapted to ride in the annular guideway 6. This plate also carries a central bearing 10, which is swiveled at 11 to 5 the upper wall of the depression 5. Recesses 12 are formed in the plate 2, which are adapted to receive pencils of graphite 14, which are preferably spring-pressed by means of springs 15 or operated bygravity. The axle-bearing 7 O 7 is bifurcated and carries on each leg at its lower extremity a journal-box 16, which is adapted to snugly fit over the contracted ends 18 of the axle-bearings 7. This journal-box is formed with beveled ends 19, and an elongated opening 20 is formed in its walls to receive the bolt 21, which is formed witha coneshaped head 22 on one end and screw-threaded on its other end, as shown at 23, for the purpose of receiving a washer 24, having outwardly-extending wings 25, and a spring 26 encircles the bolt and bears against the nut 27.

In lieu of the washer 25 and spiral spring 26 the construction as shown in Fig. 8 of the modified form may be adopted. In this form 5 24 indicates a washer of somewhat conoidal v form. The spring 26 is of ring-like form, being interposed between and bearing against washer 24 and nut 27. This bolt 21 passes through the elongated opening 20 and thence 9 through the contracted portion 18 of the axlebearing 7. The axle-bearings 7 are provided with downward extensions 28, which fit into the neck 29, formed in the hub 30 of the wheel 31. The axle 32 of the Wheelextends into the journal-box, as shown in Fig. 2 of the drawings. Lubricating-blocks 33 are secured in the journal-box, these blocks being preferably formed of graphite or other suitable material and are spring-pressed upwardly by means of springs 34, assuring a constant contact on the under face of the axle. To increase the lubrication of the upper portion of the axle, I form a suitable opening 35 in the under face of the contracted portion 18 and place therein graphite or like substance, which is also preferably spring-pressed by a spring 37, as illustrated in Fig. 3 of the drawings; but the spring may be dispensed with and the lubricant applied to the axle by gravity.

It will be noted that by the peculiar construction of the spring-pressed bolt 21 all rattling and jar will be successfully obviated. Furthermore, by reason of the inclined sides of the washer 25 of the cone-shaped head 22 bearing against the beveled edges of the journal-boxes 16 an adjustment is obtained that as the journal-box or axle wears away the tension of the springs 26 will tend to draw the head of the bolt toward washer 24: and elevate journal-box 16. It will also be observed that the journal-boxes will be dust-proof and that the same may be easily taken apart and refilled with a lubricant when desired.

The j ournal-bearings of the forward wheels, as shown in Fig. 10, may be formed in two separate parts, 7 7 denoting the legs, and 8 rivets for securing the same rigidly together, the advantage of this construction being that a cheaper casting can be made.

By reason of the peculiar construction of the downwardly-extending portion 28, hearing in the annular contracted neck portion 29 in the hub of the wheel, spreading of the journal bearings will be effectually pre' vented.

By reason of the mounting of the journalbearings and the peculiar construction of the journal-boxes a truck is constructed that may be easily moved from place to place with the heaviest loads, and, furthermore, all jar and rattling will be effectually taken up by the journal-boxes.

The many other advantages obtained by my improved truck will be readily apparent from the foregoing description when taken in connection with the accompanying drawings.

It will be understood that various changes may be made in the details of construction without departing from the general spirit of my invention.

Having fully described my invention, What I claim as new, and desire to secure by Letters Patent, is-

1. The combination with a truck-platform, and a plate secured thereto and formed with a central depression and an annular guideway, of an axle-bearing composed of a disk formed with a central bearing socketed in the central depression of and pivotally secured to said plate, an annular flange fitting in said annular guideway, and depending legs provided with journal-bearings.

2. The combination of a truck-platform and a plate secured thereto and formed with a central depression, an annular guideway and concentrically disposed recesses, with a disk formed with a central bearing socketed in the depression of said plate and swiveled therein, an annular flange fitting in said guideway and depending axle-bearings.

3. In a device for attaching wheels to trucks, the combination of a plate adapted to be secured to a truck-platform, a disk swiveled to said plate and having depending legs provided with journal-bearings and downwardly-projecting extensions adapted to engage the hub of a wheel.

4. In a device for attaching wheels to trucks, 7

the combination of a plate adapted to besecured to a truck-platform, a disk swiveled to said plate, legs depending from said disk, hollow journal-boxes fitting over the ends of said legs and provided with slots, bolts extending through said slots and through the legs, said bolts having cone-shaped heads, Washers arranged on the said bolts and formed with outwardly-extending wing-nuts on the ends of said bolts and springs arranged between the nuts and washers.

In testimony whereof I affix my signature in the presence of two witnesses.
