PA ENT 2341 roan, 0E TARBANQALABAMA v SPIKE rULLnR This invention;Tappertains devices for extracting large nails, spikesandz the like and 7 "more particularly to uja spike'puller ior rail- 7 .tion is to provide a nov'elrailroad spike puller embodying body block for. engaging the rail; and w e crating; leveif carrying Claws for engaging a "spike on either side of the rail; whereby the sp'ikesean be conveniently lanclieasily operated froin each side of thera1l iwithout undue exertion on the part ;of the i 1 As turther-obpctoff the invention is the J irproyision 'ofnove'l" clan1pi-ng members associatedwith the body block for engagingthe T "rail to hold theblo'ck in proper position on the V railagainst movement during actuation of the operating lever.

i A further ebject tor tlle ifiventlOn is the I provisionof locking membersfor clamps, so 1 as to insurethe proper holding of the-clamps in engagement with th l ff ll. p V further" object of the I invention is the I provision of. 'ine'ans carried by :the opposite i ends" of the body 'blockwh'ereby the: same can oe-re'adily graspedto facilitate the slidingoi' v [the block along the rail to"diilerentp'ositions thereon. 1

A still furtherobjeet ofthe invention is the provision of a railroadjspike extractor'of the above character," which will be durable end efiicient in use; one tliatj 'will be simple and easy to lnanufac'ture, and one 'which can placed uponthe market at reasonable cost."

With these and other objects in View, the

invention consistsin the novel construction,

arrangement and formation! of parts, as will bfef hereinafter more specifically described,- lclaimed, and lllu strated n the accompanying drawings, "in whichidrawings Figure 1 'isaside elevation of the iinproved spike extractor showlngthe same in operative clamped position on arail;

v Referring to the drawings in detail, where in similar reference characters designate coremployed for holding the rails on the ties.

I The improved spike puller Acoinprisesza base block 20 which can havefits outer face curved transversely if preferred. The lower face of the base block 20 is providedwith a longitudinally extending groove 21 for snugly receiving. the head or ball "12 ota-rail and the flanges '22 defined by said groove engage the opposite sides oftheballof the; rail and prevent lateral shifting of the block; 7 -The block'is'provided on itsupper face adijacenteach end thereof with transversely extending grooves 23 and intermediate its ends i and between the grooves 23 with a central transverse groove 24. The block is provided with a longitudinally extending central'bore 25 which receives a removable longitudinally extending pivot 26 which, as shown, terminates short of the endtransverse groove 23. This pin 26 has rockably mounted thereon the operating lever 27 of the spike puller and the groove 24. is so arranged that the lever can .be

swung from one side of the block to the other and the lever on each side and above its pivot carries

spike extracting claws

28 and 29. These clawsare rockably carried by the lever and so arranged that one claw can. be used for'one side of the rail forjextractingspikes; while the other claw can housed on the other side of the rail for extracting spikes. The J lever'27, as shown, isprovided with a rela-' tively short handle, but' it'is to be understood that an extension hand therewith if desired.

' In order to hold thebase block on the rail grip can be associatedagainst longitudinal movement and inorder .to further brace the sameagainst lateral shifting during the extracting of a spike,

novel clamps

30 and 31 arecarried by the opposite ends of the block. 7 Each clamp includes jaws 32' and 33 which depend from the opposite sides of the base block 21 and these jawshave formed on their upper end inwardly extending pivot ears 34. The base block itself on thefopp'osite side of the longitudinal bore 25 is provided with side bores 35 which extend through or communicate withthe' end: transverse grooves 23 and the cars 34 are placed in said grooves after which the pivot pins 36'are slid in the bores 35. This effectively holdsthe jaws in position for f swinging movement. The lower ends of the jaws. are provided iwith inwardly directed books 37 for engaging the base flanges 14 of the rails and thejaws above the hooks are provided with blocks 38 for clamping en- .gagement with the-Web ofthe rail. HA contractile coil spring connects the two jaws together on each side of the pivot'point thereof and normally tends to swing. the jaws in open position out of clamping engagement with therailr '1.

When it is desired to clamp the base block inposition swinginglatches 40, carried by the base block are moved into engagement with the jaws and these latches effectively holdthej aws in clamping position. Each of the swinging latchesAO carry a manipulating handle 41. v.

In operation of my; improved device, when 'itis desired to extract the spikes from the tie the baseblock is placed on the rail inthe desired position and held in place by the;

1 clamps after which the lever 27 is swung to one side and the claw' is inserted over the headof the'spike. Thelever is now moved upwardly. and the spike will be conveniently and expeditiously pulled from the tie. i

In a device of this kind, spikes can be cone veniently removed from the ties on high 'trestles andjthe like inthat spikes can be removed from both sides of the rail from the center of the trestles. Y Y

The spike puller can be conveniently moved along the rail from place to place by grasping the pivoted bail handles 42 carried by.

each end of the block for this purpose.

Changes in details maybe made Without departing fromthe spirit or the scope of this invention, but 1 Y What I claim as new is: J E 71., A railroad spike puller comprising a base block, means carried by the opposite ends of thebase blockfor clamping engagement ing means for engaging the base flanges of a rail, means carried by the blOCk-IEOI" holding the jaws" in gripping contact with the-raiL-a swinging operatmg'lever carriedfby the base block, intermediate the'clamps for swinging movement of eachsideofthe base block, and pivot-ed claws carried by the leverabove and on the same side of the pivot pointthereof.

3. A railroad spike remover comprising a longitudinally-extending base block having a: groove in its lower facefor receiving the ball of a rail, the base block beingprovided with end transverse grooves and xan intermediatetransverse groove, the base block being also-providedwith a longitudinally extending central bore openinginto the intermediate transverse groove and side longitudinally extending bores opening into the end transverse groove, pivot pins mounted in said bores, allever rockably mounted on the pivot pin mounted in the-central longitudinalbore and arranged in the intermediate transverse groove, claws rockably' car- ,riedby the lever above and on the same side of the pivot point of the lever, clamps for each end of the block forengaging the rail each, including jaws having inwardly directed "piv- J ,ot ears extending into the end transverse grooves, pivot pins extending through the pivot ears and into theside longitudinally extending bores, andswinging latches for engaging the clamping contact with the rail,

an elongated body-(having a longitudinally extending groove 1n- 1tslower face for rejaws for holding the samein 4. A railroad spike extractor'comprising ceiving the ball of a rail, a swinging leven' carried by the base'block, spike engaging claws rockablysecured tofthe lever above and r 'on the same side of the pivot noint of said lever, a clamp carried by the base block including jaws arranged on each side of the base block and pivotally'connected thereto,

swinging latches carried by the base bleak for movement overthe jaws for, moving and holding' the same in contact with the rail, each jaw including a lower hooked end for engaging the base flange of a rail and an inwardly directed jaw base for engaging the web of the rail.
