IMPROVE!) RAILROAD PUSHING-JACK.

The Schedule referred to in these Letters Patent and making part of the same To all ywhom it 'may concern Be it known that I, ALFRED FREEMAN, of the city of Peo1ia,in the county of Peoria, and in the State of Illinois, have invented a new and improved Railroad Pushing-Jack; and do hereby declare that the following is a full, clear,aud exact description thereof, reference heilig had to the annexed drawings, making a part of vthis specification, in which like letters of reference refer to like parts, and in which- Figure l represents -a perspective view.

i Figure' 2 is an elevation.

Figure 3 is a view showing operation of link.

Figure 4 is a front elevation of shoe.

Figure 6 is a side elevation of shoe.

Figure 7 is a plan of end of lever and shoe or attachment.

Figure 8 is asuperiicial view of shoe.

Figure 9 is a section of shoe.

Figure 10 is a view of spiked hook.

Figure 11 isa view of new head-plate or modificationof former jack.

This invention is an improvement on my railroad lpushing-jack, patented June 29, 1869, and consists of an attachment to the forward end of the horizontal lever of jack, by which a hold on end of car, for the lever, is maintained during the operation of moving car.

The shoe A is of `a rectangular form,to receive the -lower corner of a car, D, and has a horizontal extension or heel, about two inches long, terminating in twoeyes, between which is received the eye g, of the plate laat end of horizontal lever B, to form a hinge,

the said plate h being a modiflcationof the former forward point of said lever B. Y

,The lower jaw, c, of this clamp or shoe A, has a spnr,f,'..on its upper .snrfacelong enough to take a goodv hold in the bottom of a At the rear end of shoe A,'is an oscillating spiked clamp, d, attached, by a forked stern, to the bolt g, or jointl uniting the shoe A to the end of .the jack, terminating in ahorizontal spiked head, e, pointing toward the car, into which it is driven by a blow.

The upper surface of the angle of the clamp has a notch, large enough to receive the end of a link, l, `which is fastened, by means of a riug-bolt, staple, or equivalent device, to the upper surface of the lever B.

The combination of the spur f and the spiked clamp d forms a strong and ,secure and ready attachment of the shoe A to the corner of acar. r I For the purpose of adapting the connection of this shoe to cars of either soft or hard wood, and to obviate objections of railroad-managers, I also make the following addition to fasteniugs, either of which can be used at pleasure, viz: i

The upper, or vertical arm b, of shoe A, is slotted at m, to receive the end of a staple, It, projecting from the corner of a car, far enoughin its rear toV admit a bolt, fi, between the surface of the shoe and eyeof staple, the two, the, slot and staple, forming a separate and ready and secure attachment to cars, as the sta-v ple can be a permanent thing in a car. i

A li k, l, is attached to the surface of lever B, by stapleor other fastening.

The pushing-jack, of which the above is an irnprovement, consists of a horizontal bar or lever, adinstable by eyes and bolt to required height on a vertical or inclined leg, which terminates in a forked foot, which binds the rail below, to make a fnlcrum. Reference is had to said patent for a more complete desoliption.

The operation of this device isas followsz' The shoeA is brought to the corner of `the car D tohe moved, the vertical arm b pressing against the vertical end of car, and the spur. f,on the lower jaw c, of the'shoe. or clamp A, driven :upward into the car. The point of the spiked clamp d is then. driven into the car, the inclination of the spike heilig so coustructed as to draw the shoe and spur f into the wood-work of car at each moment of its insertion, and thus form a strong and ready point of operation for the jack.

This combination of the hooked staple or oscillating clamp d, and the auxiliary spur f, together with the slot Im, bolt i, and permanent staple k, (in the car,) is

designed to make this device available for its application to cars of either hard or soft wood, the operator using either mode of `attachment at his pleasure.

To relnove the shoe A from car, the spiked oscillating hook il is withdrawn, by simply raising the lever, and bringing the free end of the link 1,'attached to lever, over the notch on the angle of the hook d, when a slight depression of lever releases the hook. f The superiority of the forked hook d over those with a single stem, forming no adequate brace, and in which the hook is liable to release itself, is obvious, as the forked form is not liable to these motions, and consequently does notinjure the wood-work of car unnecessarily. v p

Having thus fully described my invention,

What I claim therein as new, and desire to secure by Letters Patent, is

1. 'lhe shoe A, provided with the spiked clamp d, and auxiliary spunf, combined and operating as described, and the additional fastening, by means of the slot m in shoe, and fixed staple 7:, and bolt, as may be required, in combination with above, constructed and used substantially in the manner and forthe purposes set forth.

2. The lever B, provided with the link l, in combination with the spiked clamp d, constructed and operating as described.

In testimony that I claim the foregoing, I have hereunto set my hand, this 13th day of July, 1869.

Witnesses: ALFRED FREEMAN.
