HAND-CAR AND TRACK-=RAISER.

SPECIFICATION forming part of Letters Patent No. 393,015, dated November 20, 1888.

Application filed June 29, 1888. Serial No. 278,550. (No model.)

To all whom it may concern.-

Be it known that I, ll/IARTIN LEE, a citizen of the United States, residing at Alma City, in the county of Waseca and State of Minnesota, have invented new and useful Improvements in a Hand-Oar and Track-Raiser, of which the following is a specification.

My invention relates to a combined hand-car and track-raiser, having for its object to provide suitable simple and portable raising devices attached to a hand-car, whereby the track may be raised at any point to repair or insert sleepers.

The invention consists in a certain novel construction and arrangement of devices, fully set forth hereinafter in connection with the accompanying drawings, wherein- Figure 1 is a perspective view of a hand-car provided with the track-raiser embodying my improvements. Fig. 2 is a bottom plan view of the same. Fig. 3 is a transverse sectional view on the line av x of Fig. 2, showing the clutches engaged with the track and the device in position to raise the same. Fig. 4 is a longitudinal central sectional view with the clutches raised out of engagement with the tracks. Fig. 5 is a detail view of one of the raising-levers. Fig. 6 is a detail view showing the spring-dog which looks the vertical shaft in place.

Referring to the drawings, A designates a hand-car of the ordinary and well-known construction provided with the wheels at a, which are mounted on rigid axles a a. On a transverse shaft, a*, which is mounted on the under side of the car parallel with and adjacent to one of the axles, is arranged the gearwvheel a, which meshes with a pinion, a, on the said axle, and B designates the operating-lever,which is mounted on suitable standards, I) b, on the upper side of the car, and is provided with the arm b, connected at its free end to a suitable crank, of, in the shaft a by means of the rod or link b which passes through an opening, a, in the platform of the car.

A transverse opening, 0, is formed in the platform of the car, and near the ends of the same, adjacent to the sides of the car, are the vertical movable standards D, which are mounted in openings 6 in the plates E, which are aflixed to the platform of the car and excent ribs.

tend over the opening therein. These standards are preferably squared, and fit in the squared openings 6, to prevent them from turning, and they are provided at their lower ends with the pivoted or swiveled feet or bases cl (1, adapted to bear on the ground between the tracks, and at their upper ends with the adja cent parallel racks d d, which are formed by bending a flat extension of the standard on itself and providing the edges with ratchet-teeth. Spring-actuated dogs F are mounted on the plates E, and are adapted to engage sockets d in the standards when the latter are raised, as shown in Fig. 4 of the drawings, and the said dogs are provided at their free ends with the vertical studs or handles f, whereby they may be disengaged from the said sockets by the foot of the operator. (The dogs are adapted to engage the sockets d automatically when the standards are raised.)

In bearings 9 in the transverse plates G, which are affixed to the platform of the car over the opening 0 therein, are mounted the vertical raising-bars H H, which are provided at their upper ends with the heads or nuts h h and at their lower ends with the hooksor cams hh, the said bars being so arranged that when they are extended downward they will pass at their lower ends on the inner sides of the rails,wh'ereby when they are turned the hooks or cams engage under the treads of the adja The raising-bars are further provided, just above the said hooks or cams, with the shoulders k and also with the collars h, adjacent to the shoulders, the portions of the bars between the shoulders and the collars forming spindles, which are mounted in bear ingsjj near the ends of the clutch-bar J. The bar Jis provided at its ends with the depending arms or studs j which are adapted topass down on the outer sides of the rails.

It will be observed that when the raising bars are turned to engage the hooks or cams on their lower ends with the treads of the rails the latter are firmly clamped between the hooks or cams and thedepending arms or studs 9', the said parts thus forming clutches.

K represents a vertical shaft, which is mounted in a bearing, Z, in the plate L,(which is arranged across the center of the opening 0,) and it is provided at its lower end with a finger, lo, which is adapted to be engaged under the center of the clutch-bar J, whereby the latter (and consequently the raisin g-bars which are attached thereto) may be raised out of contact with the rails when the hand-car is in motion. This shaft is provided at its upper end with a hand-wheel, k, to enable it to be rerated and raised, and on the plate above mentioned is arranged a spring-actuated dog, M, engaging'soekets k k in the shaft K in either its raised or lowered position, thesaid dog being adapted to prevent both vertical and retary movement of the shaft.

The shaft K is provided below the platform of the car with the lateral arms N N, which are connected, respectively, to similar arms, 0 O, on the raising-bars by means of connecting-links l? 1?, whereby when the said shaft is turned the raising-bars are similarly operated to enable the hooks or cams on their lower ends to be engaged with the rails or disengaged therefrom. Then the hooks or cams are engaged with the rails, the vertical shaft is locked against movement by the dog above mentioned, which automatically engages one of the sockets k From the above description it will be understood that by proper manipulation of the shaft K the clutches may be lowered and engaged firmly with both rails simultaneously and locked inthe said engaged position, and also that the clutches may be disengaged and raised simultaneously and locked in the latter position.

I will now proceed to describe the mechanism for raising the rail after the raising-bars are engaged therewith and the standards are bearing at their lower ends on the ground.

It It represent vertical links,which are provided at their lower ends with sockets r 1", swiveledon the raising-bars below the heads or nuts thereon, and to the upper ends of the links are pivoted the raising-leversS S. The head of the raisin g-lever consists of a flat plate, 8, provided at its upper edge withtheinturncd hooks s 8, adapted to engage the ratchet-teeth on the upper end of the standard and the intermediatc guiding tongue, s, between the hooks, and adapted to operate between the rack-s d d, and thereby guide the vertical movement of the lever.

It will be observed that the links R are swiveled loosely on the raising-bars, whereby the hooks s s on the levers may be engaged, respectively,with the racks on the standards. The center of the heads or plates 8 are pivoted on the upper ends of the links, so that the said hooks are on opposite sides of the pivot, and therefore to raise the track operate the levers to alternately engage their hooks with corresponding teeth in the racks-name] y, engage the inner hooks, s, with the corresponding rack, then engage the outer hook with the next higher tooth of the corresponding rack, then engage the inner hook with the neXt higher tooth of the first-mentioned rack, and so on until the rail is raised sufficiently, (it being understood that both levers may be operated at the same time, so that both rails are raised equally, or either lever may be operated to raise one track.)

In the improved track raiser the strain is entirely sustained by the parts of the raising mechanism, for the reason that the raisingbars are connected at their lower ends to the rails by means of the clutches, the standards bear directly on the ground, and the raisinglevers which operate on the standards are connected directly to the raising-bars, thus preventing strain from falling on the hand-car. The rails are held in their raised position by the levers, both hooks of which are allowed to engage approximately-opposite teeth of the ad'- jacent racks.

Having thus described the invention, I claim 1. In a track-raiser, the combination of the standard provided with parallel vertical racks, the raising-bars provided at their lower ends with clutches to engage the track-rail, and the levers connected to the raising-bars and provided with hooks s 8, adapted to alternately engage the racks on the standards, substantially as specified.
