DEVICE FOR USE IN EXTRACTING RAILROAD- -TIES, 800.

SPECIFICATION forming part of Letters Patent No. 637,843, dated November 28, 1899.

Application filed June 13,1899.

To all whom it may concern:

Be it known that I, ALBERT ZETTER, a citizen of the United States,residing at Freeburg, in the county of St. Clair and State of Illinois, have invented certain new and useful Improvements in Devices for Use in Extracting Railroad-Ties and the Like; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention relates to an improvement in devices for use in extracting railroad-ties and the like of that general class clearly illustrated in the Patent No. 623,300, just issued to myself and hearing date April 18, 189$}.

An object of the invention is to make a construction'that will be capable of either pulling or shoving out a tie without any change of position of the device, and a further object is to so construct the device as to afford the greatest possible simplicity, strength, and efficiency in operation.

The invention contemplates the peculiar arrangement and combinations of parts hereinafter to be fully described, and definitely pointed out in the claims.

In the accompanying drawings, wherein for the mere sake of illustration an embodiment of the invention is delineated, like letters of reference designate corresponding parts in the several views.

Figure l is a plan view of the device in operative position, a section of track being shown in dotted lines. Fig. 2 is a side view of the same, the track being shown in crosssection. Fig. 3 is a detail view of a modified form of grip; and Fig. 4 is a detail View of the double ratchet, the end of the bracket being broken off.

Referring to the drawings, A designates a bracket or framework to which the different parts of the device are secured and within which they work. This bracket has a forward flattened extension a, to the edge of which are securely attached a pair of lower brace-rods B, each of which is provided with a stop I) and hook 19, adapted to engage the under face of a track-rail. An upper bracerod 13, adapted to engage over a track-rail, has a bifurcated rear portion, the arms 5 b of which are pivotally secured at b to the ex- "inclosed portions 0 c of the bracket.

tension at. This brace-rod has a notched portion at its forward end corresponding in contour with the tread-surface of a rail.

The forward extension a and a corresponding rear extension a constitute lateral supporting means for the device when in operation.

As a means for withdrawing or shoving out a tie a rack-bar C is provided, the same being adapted to slide within and be guided by the The grip at the forward end of the rack-bar is of peculiar style to enable the same bar to be readily used either to grip or shove the tie.

In the form shown in Figs. 1 and 2 of the drawings the bar has an extension 01, angular in cross-section, having an aperture in which a locking-pin d fits when the grip is attached. The grip comprises a substantially rectangular plate D, having a central aperture of a size to fit over the extension cl, and the grippingarms D D, pivoted at the opposite sides of the plate. To look the arms to the end of a tie when the same is to be withdrawn, an adjustingscrew D connects the same and is designed to spread or tighten them. When it is desired to shove out a tie, all that is neces- 'sary is to remove the locking-pin d and the grip, when the extension at will be used as a plunger, though in many instances the grip need not be disturbed at all.

In the modified form of grip illustrated in Fig. 3 the plate D is formed of flanges integral with the draw-bar, and itself serves as a plunger when shoving out a tie. The opposite flanges in this form have elongated slots a in which hooked ends d of the grippingarms loosely engage and are readily detachable therefrom.

Pivotallysecured in ears 6 upon the bracket is a pinion E, which engages the toothed upper surface of the rack-bar. This pinion is to be used when the device is being used to withdraw a tie, and to operate the same the following mechanism is employed: The shaft upon which the pinion is mounted extends at its respective ends outward slightly beyond the plane of the ears. Rigidly attached to one of the extension portions of this shaft is a double ratchet-wheel F, in the center of which is pivoted an actuating-lever G, which in turn is provided with a relatively broad clearly shown by the drawings.

pawl g, adapted to engage the teeth of both sections of the ratchet-Wheel. It will thus be seen that by actuating the lever G, the grip having first been secured to the tie, the ratchetwheel will be revolved in the direction of the arrow, Fig. 2, and consequently the pinion will turn in the same direction through the medium of its shaft, thereby operating upon the rack-bar so as to force the same rearward. In this manner a tie is withdrawn. At the opposite end of the axle to which the ratchetwheel is located I mount a wheel H, having pockets h in its periphery designed to receive the end of a bar or lever to revolve the pinion in case the operating-lever and ratchet-wheel, just above described,become inoperative from damage or otherwise.

Now when it is desired to shove out a tie the grip is removed from the end of the rackbar and the lever G thrown back into the position shown by dotted lines, Fig. 2, with its pawl out of operative position, and the following mechanism then employed: A lever K is pivoted between ears 6 on the bracket, corresponding to the ears e,before referred to, and this lever is provided to both sides of its pivot-point with lugs 7s 7s, to which in turn are pivoted what I will term, respectively, an upper and a lower pawl 70 the former being somewhat longer than the latter, as The purpose of having these peculiarly-arranged pawls is in order to have a continuous actuating means for the rack-bar during both the forward and rearward movement of the lever K, for it will be obvious that when the said lever is thrown forward the upper pawl 7t will work upon the rack-bar, and when the lever is thrown rearward the lower pawl 7.2 will operate the rackbar, the pivot-point of the lever being, as described, intermediate the pawls.

When the device is being used to draw out a tie, the lever K, with its pawls, will of course be thrown back out of operative position.

It will be apparent that many details of the construction and arrangement of parts shown herein may be altered without departing from the nature and principle of the invention, and it is to be understood that while the device has been described as especially adaptable to removing railroad-ties, yet it is not the intention to be necessarily restricted thereto, since the character of the device renders it applicable and efficient for many other analogous uses.

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