To ZZ whom i? lmay concern:

Be it known that l', lViLLiiiir S. A. VViLDnii, a citizen ot the United States, residing at 'Tallejo, in tlie county oit Solano and State of California, have invented a new and useful improvement in Devices tor Removing and Replacing Railroad Ties, of which the tollowing is a specification.

This invention relates to a device tor removing and replacing railroad ties and especially to improvements on the structure shown in my Patent- No. 1,078,182, issued November 11, 1918, and entitled Bevice for removing and replacing railroad ties.

One ot the objects ot the present invention is to provide a simple, substantial, easily operated device by which the old ties supporting a railroad track may be easily removed and replaced by new ties without disturbing oi' removing the soil ot the surround ing road bed.

Another object ot the invention is to provide novel means for securing the device in position on the rails when in operation and in conjunction therewith means permitting adjusting ot the device when rails ot varying size are encountered or when working on curves.

.Another objectot the invention is to provide means to prevent short circiiiting between rails when working so as to avoid accidental operation ot' block signals, alarm ems or other electric actuated devices v. i en employed.

Another object ot the invention is to provide a novel pawl and lever bearing support by which power is transmitted when removing and replacing ties, and also to provide an adjustable plow as will be hereinafter described.

lurther objects will hereinafter appear.

rThe invention consists ot the parts and the construction, combination and arrangement of parts as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which- F ig. 1 is a side elevation of the railroad tie removing and replacing device showing it in operating position on the rails.

1Referring tothe drawings in detail, il iiiuicates in particular road bed upon which is placed the usual torni ot ties 2 and rails 3.

the purpose o'l" the present invention. as previously stated, is to provide meansl bv which old or partially rotted ties inav be ifemoved and replaced by new ones ivitliovt disturbing or removing the surrounding soil orgravel in the road bed. This is accomb l hy providing a special torni ot tie iich consists ot a pair et parallel dis- `terspaced side plates 1l, suitably seegether or as here shown by nieaiis helts. Carried bythe plates et, upon rollers appropriately jouriialled between the plates 11, is av longitudinal pusher bar 8, to which is secured a pair oie rack bars 9 and 10. lliese rack hars are engaged by pawls 11 and 12, ci? which there are two pair, one pair engagg with the rack bar 9, 'and the opposite pair -th 'the raclr bar 10. hy and are disposed in opposite sides of a. hearing member 13, which also serves as a support for main operating lever 1a, in which is secured a pair of opposed handles 15. The detail constructi n of the bearing ''.ber 123 is shown in Figs. 5 and The iig .member consists of a pair ot rings 16, ecured oi' toi-med integral with plates 1?. liese plates are interspaced, as at 18, and

'ovi'aed with superposed recesses 19 reception of the respective pawls 11 t pawls being supported in .9 and the opposite set in the rlhe bearing members or rings rlhe pawls are carrie-d v 16 therefore serve as a support for the pawls, and also for thel main operating lever as the upper' ends of the plates 17 terminate in a bracket 20, to which the handles of the main operating lever are secured by introduction into socket members 21. The upper ends of the pawls are provided with head members 22, which are adapted to be received by the recesses 19 and 19a. These recesses permit pivotal movement of the pawls therein, and also secure the pawls againstendwise removal, lateral removal of the pawls being avoided by exterior securing plates 23. (See Figs. 2 and 5.) lhe ringshaped bearing members 1G are supported in journal members 16"", formed integral with the side plates or secured thereto by means of rivets 24, (see Fig. 1,) and antifriction rollers are interposed between the jomfnal members 1G andthe ring-shaped bearing sections 16 to reduce friction to a minimum. The opposite pairs of pawls 11 and 12, as previously stated, are pivotally mounted in the recesses 19 and 19PL supporting the saine, and their outer ends are thus free to drop by gravity into engagement with the rack members 9 and 10. A rocking or oscillating movement transmitted to the bearing members 16 by means of the handles 15 will therefore impart a reciprocal movement to the pawls 11 and 12, thereby causing these to engage the teeth of the rack bars alternately and transmit movement theretofin the direction of arrow a.

One end of the bar 8 is provided with a downwardly projecting jaw 26, which is adapted to engage with the end of a tie (see Fig. 1,) and as the bar travels in the direc tion of arrow (L, when a rocking movement is transmitted through the handles 15, it can be seen that the jaw will engage the tie and force it inwardly in under the rails, thus removing the old tie and simultaneously inserting a new tie. To limit the rocking movement of the raclr member or lever 14, l provi-de a latch 27. This latch is shown in Figs. 1, 2 and 1l,l and merely consists of' a plate which is pivotally mounted between the side. plates 4. The upper two pins 28 formed on the plate 27 engage the upperl edge of the plates 4 and thereby prevents it from dropping downwardly between the same. The lower pins pass through the plates 4 and serve as a pivotal mounting for the same. Downward rocking movement of the lever 14 is limited when the bracket 20 strikes the plate 27. rl`his prevents the pawls from being lifted out of engagement with the rack teeth when ordinarily operating, but .i-evcrsal of the plate 27 by swinging it backwardly permits a further rocking movement of the lever 14 which is sufiicient to .lift the pawls 11 and 12 out of engagement with the rack teeth. This excess i'novement is however only resorted to when it is desired to pull the push bar 8 to extended position when a new tie. is to be inserted.

For the purpose of limiting the outw movement of the push bar 8, I form a notch 28 at one end thereof. T his notch is engaged by a pawl 29 when the notch registers therewith, this pawl being provided for no other purpose than that of limiting the outward movement of the push bar. A handle 30 is formed thereon which permits lifting the pawl if it should be desirable to entirely remove the push bar, for instance for inspection, repairs or otherwise.

In order to secure the tie jaclr upon the rails when it is placed in position with relation to a tie, it is accomplished by forming suitable recesses 32 in the lower edges of the side plates 4, which are adapted to straddle the tracks as shown in F ig. 1. Secured to the side plates 4, and connecting the same, is a gripping member 33 which is more clearly illustrated in Figs. 1, 2 and 7. The gripping member consists of a longitudinally extending center portion 34, having u width equal to the spacing Vbetween the plates 4. This portion is drilled, as at 35, and bolts passing` therethrough secure the gripping member between the plates. rlhe gripping member is otherwise provided with a pair of cross arms 36, a pair of rearwardly extending brace arms 37, and a pair of e* gaging shoes 3S. These shoes pass under the base flange of the rail as shown in F ig. 1, and thereby secures the jack as a whole against lateral movement with relation to the rails. The gripping member just described is not only secured to the side plates by means of bolts passing through the drilled openings 35, but it is also secured thereto by tie rods 39V and fastened at its upper end as at 41, and at their lower ends engages perforated ears 40 formed adjacent and 37 of excess strain when the jack is in operation.v

A gripping or engaging member, similar to that shown in Fig. 7, is employed for the purpose of engaging the Vopposite rail. h is member is shown in Figs'2, 3' and 8, and is identical to the engaging member shown in Fig. 7, with the exception that longitudinal adjustment is provided to take care of rails ofvarying size and to increase the distanre between the engaging members when worlringoncurves. The longitudinal center section of the engaging member shown in F 8 is provided with a rectangular-shaped opening extending therethrough. This opening is lined with an insulating member 44. side insulating plates and 46, and with an end boss 47, which is plugged by an insu` lating member 48. Extending through the avoided and interference et. any kind with railway operation can be prevented as the j ack may be quickly removed or replaced to permit the passage ot trains, etc.

The bolts 5, securing the side plates Vtogether, serve as bearings for the rollers 7, between which the pusher bar travels, and these in turn serve as spacers between the plates and thereby eliminating Yfurther unnecessary mechanisms or. complications.

The jack here shownis exceedingly simple and substantial iii construction. rllliere is only one adjustment provided, tio-wit, the rear engaging member and the adjusting screw employed in conjunction therewith. Unslrilled labor may be employed due to the simplicity and compactness of the structure,

and it may therefore be operated by any one without skilled attention or supciwision.V

While certain features of the present invention are more or less specilically illustrated, l wish it understood that various changes in form and proportion may be resorted to within the scope of the appended claims, similarly that the materials and tinish ott the several parts employed may be such'as the experience and judgment ot the manufacturer may dictateeor varying uses may demand.
