WILLIAIVI E. QUINN, OF SI-IREVEPORT, LOUISIANA, ASSIGNOR TO QUINN 8c ATKINS JOURNAL JACK ATTACHMENT COMPANY, OF SI-IREVEPORT, LOUISIANA, A CORPO- RATION OF LOUISIANA.

JOURNAL-JACK.

To all 'wil om t may concern Be it known that I, vWnmmir E. QUINN, a citizen of the United States, residing at Shreveport, parish of Caddo, State of Louisiana, have invented a certain new and useful Improvement in Journal-Jacks, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

In order to remove a ournal brass from a railway car it is necessary to raise the journal box from the ournal so as to relieve the pressure on the brass; t-he usual method being to place a jack on a railway tie or other support beneath the journal box and thus lift the box from below. This upward pressure on the under side of the journal box not only raises the box but, by shifting the weight to the journal on the opposite side of the car, causes the wheel and the journal on the side which is being acked up to rise. Various makeshift expedients, inconvenient and time-taking, are employed by train crews to hold down a car wheel while the corresponding` journal box is being raised; and various attempts have been made to provide the jacks themselves with some means for engaging with a car wheel to accomplish this purpose. However, because of the great variety in the size of rails, size of journals, and size and shape of journal boxes and truck side frames, a device which may perhaps operate successfully in a given situation, that is on a particular car standing upon rails of definite size, will not answer at all in other situations, that is perhaps when the same car is standing upon a track made up of hea-vier or lighter rails.

It is the object of my invention to produce a simple and efficient attachment or addition to an ordinary jack which will positively prevent a car wheel from rising when its journal box is being jacked up in any situation which may be encountered in railroad practice without making it necessary for the workmen to rely upon their ingenuity in order to secure a quick removal of a journal brass when the occasion presents itself.

In carrying out my invention, I mount upon the stand or base of any usual or preferred style of jack a radially-projecting,

pointed strut in the form of a pawl fulcrumed toward its butt end and provide a wedge block which may be dropped between the butt end of the pawl and the base or stand of the jack for the purpose of filling the space between the inner end of the pawl and the jack when the outer end of the pawl\has come into engagement with a car wheel; the wedge block serving as an automatically-adjustable filling piece which at all times affords a solid backing for the pawl, regardless of the angular position of the latter and thus permits the thrust of the pawl to be transmitted directly to the base or stand of the ack. The strut may be connected to the jack by a pin and slot device which will permit the strut to vary not only its angular position but also the distance from its outer end to the jack in any given angular position, the wedge block being designed so that it will always afford a solid backing for the pawl. In order to take care of extreme conditions, the strut may be provided at its outer end with an auxiliary pawl which will ordinarily hang down out of the way, but which, when occasion demands, may be swung up so as to form a continuation of the strut.

In one of its aspects my invention may therefore be regarded as comprising a jack having a radially-projecting automaticallyadjustable strut arranged thereon in such a way that the outer end of the strut will always find a bearing point on a car wheel to enable it to hold the car wheel down when the ournal box is jacked up, while the inner end always has a solid backing which will transmit thrusts directly to the base or stand of the jack.

The various features of novelty whereby my invention is characterized will hereinafter be pointed out with particularity in the claims; but for a full understanding of my invention and of its objects and advantages, reference may be had to the following detailed description taken in connection with the accompanying drawing, wherein:

Figure l is a view, partly in section and partly in elevation, illustrating the jacking up of a journal box bymeans of a jack arranged in accordance with a preferred form of my invent-ion, the jack itself being shown in side elevation; Fig. 2 is a view corresponding to Fig. 1 and illustrating a fragment of a jack in which the automatic adment is carried a. step farther than in il; Fig'. 3 is a View Corresponding` to Q, showing a still further elaboration oit the automatic adjustment; Fig. fl is a top plan. yiew ot the strut shown in Fig. 3; Fig. is a top plan View of the base or stand oit' a jaelr which has the supporting ears for the strut cast integral therewith; and Fig. (3 is a View similar to Fig. 5 showing the supporting ears for the strut Carried by a band or strap which may be secured in any suitable Way about a portion of the base or stand of the jack.

Referring to Fig. l of the dranf'ing, l represents the base or stand of a jack of any suitable construction and 2 the movable power element carried by the base or stand. lrojecting radially from the base or stand, preferably from. a. point near an upper end thereof is a strut, 3, in the term of a paWl pointed at its outer end and having a relatively wide inner or butt end. The inner end oi the strut, in the arrangement shown, lies between a pair of ears, et, projectingout- 1uardly 'from the base or stand; these ears being' either cast integral with the base or stand as indicated in Fig. or forming part o'lg' or carried, by a strap or band,@embracing` a portion of the base or stand, as indicated in Figi'. G. A bolt, 6, passingl through the ears and the pand at some distance from the butt end of the latter, serves to hold the paivl pivotally in place.

The deyiee is adapted to be used as illustrated in Fig. l, the jack being set upon a tie, 7. or other support beneath a journal bo.\;, 8, troni which. a brass is to be removed; the jaeli being so positioned With respeet to the rail 9 that the strut or pawl Will drop down and rest upon a portion of the Wheel, l0, near the rim of the latter.

.it all rails were of the same height, all join-nale of the same diameters and length, all journal boxes and side trames ot a single standard sive and shape, if there Were no variation in the eoniigurzition of ear Wheels, the several parts which I have heretofore specifically described could be so proportioned that when the ack was placed in position the pointed end of the strut would properly engage with the ear Wheel and the butt end of the strut would bear against the side ot the base or stand of the jack so that when the jaelt was operated to raise the journal box, the Wheel Would be held down. However, there is no such uniformity in the various elements to 'which l have just referred but, on the other hand, there is a great diversity between the sizes and shapes of such elements and consequently some means must be provided Which Will permit the deyiee to adapt itself to the various conditions apt to be encountered. To this end l hare provided a Wedge block, 1l, which is adaptedY to be dropped down between the butt end ot the pawl or strut and the side of the base or stand oit the jael; so that, regardless ot the angular position which the paWl or strut Will assume when in Contact with the Wheel, the Wedge bloek will lill in solidly7 behind it so that the tlufust o the pawl or strut Will be transmitted directly to the base or stand. rihe Wedge block will ot' course be made to lit between the ears, 4l, so that it cannot Work out laterally. ln order to prevent the wedge block from bee coming lost, it may be attached to one end of a short piece ot chain, l2, whose other end is secured to some portion et the jacl. Consequently, with the device Constructed as l hare just described it, the jael; is set in place under a journal to be raised, the pawl dropping` upon the ear wheel, and the Wedge blool; then inserted behind the paivl and the adjustment is complete tor the 'Wedge block will automatically seat itselt until it solidly bridges the space between the butt end ot the paivl or strut and the side oli the base or stand ot the jaclt.- Then, when the jack is operated, the paul or strut is unyielding and 'the wheel is positively' held down. A. Wider range ot adjustment may be obtained by permitting the pawl or strut to move bodily, that is shift its fulerum radially with respect to the axis ot the jack. rlhis may be accomplished as shown in Figs. 2 and S3, by connectingv the strut or pawl, 30, to the ears, 4;, by means et a pin and slot device. ln the arrangement shown, the pin or bolt, G, passes through .round holes in the ears and through an elongated slot, 3l, in the pawl. ln this arrangement, the Wedge block ll() should be son'ienhat larger than the wedge block ll. because the range of adjustment is greater. la still further range of adjustment may be obtained by connectingv to the outer end et the strut er pawl an auxiliary strut or pawl, 300, which normally hangs down out ot the Way but, which may be sn'niig up, as shown in Fig. and thus form an extension ot' the main pau'l or strut. The auxiliary pawl may ot eourse take any suitable form. ln the arrangement shown, the auxiliary pavfl lies on the under side of the main par-:l or strut and has ears, 301, project-ine up beside the latter. all pin or bolt, 32, passes through the ears, 301, of the pawl or strut, 30. i

lt sometimes happens that the paivl or strut should be capable of being shifted angularly around the axis et the jack so as to permit the jael. to be n'orled satistao torily. lllhere the sui/Jportii'igare earried upon a band or strap as indicated in Fig. 6, this adjustment of the pawl or strut may be obtained by simply shitting` the strap or band. lVhere the ears are cast integral with the base or stand ot' the jack, the adjustment of the paWl or strut may be obtained by providing a second set et' ears,

40, angularly displaced from the ears 4 about the axis of the jack. By removing the bolt or pin, 6, the pawl or strut may be removed from between one set of ears and placed between the other as conditions demand.

I claim:

l. In combination, a jack, a pawl pivoted at its butt end to the ack so as to be capable of swinging about a horizontal axis in a plane radial to the jack, the butt end of the pawl being wide and having a considerable portion thereof lying above the pivotal axis of the pawl, and a vertically-movable wedge block lying between and engaging with said portion of the butt end of the pawl and the adjacent face of the jack.

2. In combination, a jack, a pawl pivoted at its butt end to the j aclr so as to be capable of swinging about a horizontal axis in a plane radial to the jack, the butt end of the pawl being wide and having a considerable portion thereof lying above the pivotal axis of the pawl, and a vertically-movable gravity-actuated wedge block lying` loosely between the upper portion of the butt end of the pawl andthe adjacent portion of the jack.

3. In combination, a jack having parallel ears projecting therefrom on opposite sides of a plane radial to the jack, a pawl lying with its butt end between said ears, a horizontal pivot passing through said ears and said pawl, the butt end of the pawl being wide and having a considerable portion lying above said pivot, and a vertical gravityactuated wedge block lying between said ears and engaging with both the upper portion of the butt end of the pawl and the adjacent face of the jack.

4. In combination, a jack having separated ears projecting therefrom on opposite sides of a. plane radial to the jack, a. pawl lying with its butt end between said ears, a pin and slot connection between said pawl and said ears to permit the pawl to swing about a horizontal axis and to move bodily toward and from the jack, the butt end of the pawl being comparatively wide and having a considerable portion thereof lying above the pivotal axis of the pawl, and a vertically-movable wedge block lying between said ears and engaging with the upper portion of the butt end of the pawl and with the adjacent face of the jack.

5. In combination, a jack, a pawl extendl ing radially from one side of the jack, a pin and slot connection between the inner end of the pawl and the jack for permitting the pawl to swing about a horizontal axis andalso to have a limited bodily movement toward and from the jack, the inner end of the pawl being comparatively wide measured in the vertical direction and having a considerable portion thereof lying above the pivotal axis of the pawl, and a vertical wedge block lying loosely between and in engagement with the upper portion of the inner end of the pawl and the adjacent face of the jack.
