RAIL-SPIKE PULLER.

Application filed June 1,

This invention relates to improvements in spike pullers.

The primary object of this invention is the provision of a spike, bolt, or nail puller, which is of a very compact nature, and which may be conveniently operated, with ease, to exert a powerful vpull in a vertical direction, to straight out from its socket.

A further object of this inventionis the provision of an improved spikepullin'g de vice, having an operating claw which pulls or exerts force upon'a spike in alignment with the spike, for the extraction of the same; the device embodying a powerful operating cam levermeans to exert apowerful pull upon the claw with but little manual exertion.

Utherobjects and advantages of this invention will be apparent during the course of the following detailed description.

may generally designate the spike puller, which may comprise a frame B; spike claw C slidably mounted in the frame B; and claw operating means D.

The frame B is of course of any approved reinforced construction, and thesame is of a special design, which will make the same convenient for portability, and yet designed to stand-the forces which will placed shallow supporting base 10, which isor dinarily placed directly on the topvsurface vided with the spaced vertically upstand mg gibs or

guide standards

16 and 17, having the vertical space 18 therebetween'opening at the frontpofthe frame B, and said

standards

16 and 17 being grooved at their itacinglsides, at 20 and 21 respectively, preferably for the entirelength thereofflto accommodate the reduced lu s %3 at the opposite side-s of the spike ead socket end of the claw C,-Whic'h will be subsequently described, to guide said claw C in a rectiide standards or gibs I6 and 17. u 1

At its rear end the base: 10 is provided with a batter head 27, againstwhich a perhe same includes. a relatively son may hammer in order to force the spike head into the socket ofjthe'claw spike head socket end described] The frame B furthermore comprises the cam supporting rails 35and 36 atopposite sides thereof, connected at their forward ends integral with the guide sta'ndardslfi and 17 preferably intermediate the ends ,of said guide standards; said cam supporting rails and 36 extending downwardly from their connection withthe guide rails, for connection-at their lower ends to the batter head 27 of the base 10. At the inner sides of the rails 35 and 36', arcuated cam flanges or shelves 40 and Mare preferably provided, extendingfrom immediately adjacent the guide standards 15and, 16 respectively, and at their rear ends terminating short of the base 10, as illustrated in 25, as will be'fsubsequently Figure 2 of the drawing. Upon the upper surfaces ofthese arcuated cam shelves 40 spike pulling claw C, the same includes the narrow elongated substantially flat shank 55,

which is rectangular in crosssection, and

' which at the lower end has the spike h ead socket end 25, and which at opposite sldes thereof has the reduced lugs 23 thereon whichslidably extend snugly into the guide grooves 20 and 21 to guide the vertical rectilinear movement of the claw as it is moved upwardly. The socket 30 is formed by pro viding spaced inwardly extending

flanges

56 and 57, which are adapted to grip the head of the spike F, as can readily be understood,

and the socket 30 is open at the front of the claw C; the

flanges

56 and 57 preferably being beveled to permit the same to be hammered to place beneath the head of the spike. by hammering against the batter end 27 of the base 10, in a manner which is obvious.

Referring to the operating means D, the same preferably comprises an integral L- shaped lever 60, which at the lower end thereof provides the arcuated cam engaging

lever portions

61 and 62, which are of identical formation, as illustrated in Figure 2 of the drawings, the same being spaced from each other throughout their length, and providing convex lower surfaces 64: which are adapted to ride upon the top convex surfaces of the cams 40 and 4-1. The operating lever 60 furthermore includes the lever portion 66 which may be of any approved lengtlueither providing an attaching shank, or a socket for receiving a relatively long bar therein, or the bar may be formed rigid as a part of the lever portion 66. In the specific example shown the lever portion 66 is in the form of a socket, and it extends in a general line at rightangles to the cam

operating lever portions

61 and 62, and is of course integral therewith. In the space 68 immediately adjacent the juncture of the spaced cam lever portions with the lever portion 66, said.

lever portions

61 and 62 are provided with transverse aligning openings 69 for receiving a pin 70, which also extends through an upper 'apertured end of the body of the spike claw C, as is illustrated in the drawing, and thusxthe L-shape'd lever 60 is pivotally connected at the juncture of the portions 6162 and 66 with the upper end of the claw C.

. The socket portion 66, in the specific instance shown is provided with a socket open ing therein for receiving the lower end of a relatively long bar 76, which may be the conventional standard lining bar. In lieu of such a socket the lever portion 66 may constitute the bar 76 itself, or may be formed rigid therewith, or the lever portion 66 may be merely a. shank for receiving the socket on the lower end of a bar. These are merely alternative constructions which are withinthe mechanical ability of anyone skilled in this art to apply; it being preferred to have a detachable connection of the bar 76 with the L-shaped lever 50, or to make the spike pulling device portable.

As a reinforcing feature of the L-shaped operating lever 60, the free ends of the cam engaging lever portions are connected with the forward end of a connecting brace bar portion 60, which extends in a divergent relation with the

lever portions

61 and 62, and

at its opposite end 81 the same is connected integral with the lever portion '66,. above the juncture of the lever portions 6162 and 66, as is illustrated in the drawings. This reinforces the'substantially right angled portions 6st and 66, and connects the free ends of the spaced lever portions 6162 in a stable relation. A spike knock-out projection 87 is formed integral or rigid with the free ends of the lever portions 6162, in transverse relation therewith, normally extending downwardly when the lever is in a position about to start the drawing of a spike, and which moves forwardlyand into engagement with the spike after the spike has been pulled, to knock the spike out of the claw socket 30, in a manner which is well illustrated in Figure 2 of the drawing, and which can readily be understood.

Referring to" an operation of the inven tion, the base 10 is applied as above described on a ground surface or on thetie, and the base is then, forced towards the spike until the head of the spike is received in the claw socket30. In this position of parts the operating lever 60 is positioned with the portion 66 vertical, and the lever portions 6l62 are positioned substantially horizontal with the convex surfaces thereof in engagement with the forward ends of the cams 40 and 41. After the bar 76 has been applied in the lever portion 66, the operator draws the same rearwardly, and this starts the elevation of the claw C; the convex edges of the

lever portions

61 and 62 operating on the cams 40 and i1, and incident to the radii upon which the convex edges of the said

cam lever portions

61 and 62 are formed, and incident to the formation of the cams, as the lever 60 is further rocked in order to extract the spike, said

cam lever portions

61 and 62 will permit the leverage to be increased. That is, the fulcrum points of the

lever portions

61 and 62 on the cams will move farther away from the guide vi: Ax)

forpulling spikes between closely posi

standards

16 and 17 as the claw is vertically moved upwardly, to increase the leverage action, and thereby producing-a powerful pull which increases for the major length of extraction of the spike F, and until the spike :is substantially withdrawn, when the. fulclaim of the lever portions 61 .and 62 moves -along thecams toward the

vertical guide standards

16 and 17, and when thespike is entirely withdrawn the knockout projection 87 will enter the open rear end of the socket 30 to engage the upper end of'the spike F and knock thesamefrom the clawC as illustrat-ed in Figure- 2. y In event the improvedspike puller is used t-iorsed raile, such as illustrated in Figures 6 ceiv'ing socket 293 exactly similar to. the

socket 30 above mentioned, for receivingthe head of aspike9l which is'positioned between said closely positioned rails, as

illustrated in Figures 6 and 7, and with which attachment 90 the spike 94: may be readily withdrawn, the base 10 of the frame B in this instance resting upon the top of a rail. 13.

From the foregoing description of this in-.

vention it is apparent .that a novel type of 1x spike puller has been provided, which will operate to etiiciently withdraw spikes from rails.
