RAITJWAY -SPIKE DRIVER.
, aeaioc,
description of the invention, such as will en able others skilled in the art to whioh it appertains to make and use the samea,
My invention has for its objects to provide a comparatively simple and inexpensive, yet a highly eficient durable and in every way desirable machine for driving railway spikes much more rapidly than can be done by hand. With the foregoing object in view, the invention resides in the novel features ofjconstruction and unique combinations of parts hereinafter fully described and claimed, reference being made to the accompanying drawings forming a part of this application.
Figure 1 is a side elevation partly in longitudinal section.
Fig. 2 is a top plan view.
Fig. 3 is a vertical transverse section on the plane of the line 3-3 of Fig. 1.
Fig. 4 is a fragmentary top plan view showing more particularly the manner in which the spikes are prevented from rotating in their tubular guides.
- Fig. 5 is spike guides.
In the drawings above briefly described, a car is shown, said car being preferably of substantially the same size as the well known hand cars used inrailway repair 7 work. The car includes flanged wheels 1 torun upon the railway rails 2', and a horizontal platform 3. At suitably spaced points, tubular spike guides 1 depend from the platform 3 and preferably pass slidablythrough vertical openings 5 formed through the latter, said guides bein provided with longitudinal ribs 6 receiva 1c in key-ways to prevent rotation of the guides. The several spike guides 4 are arranged to straddle the rails 2 and the spikes are dropped into said guides by hand from the upper ends thereof, whereb said spikes will be properly posltioned or driving into the ties 7. In order to prevent rotation of the spikes 8 in the guides 4, the the latter are provided with longitudinal slots, 9 to receive the projecting a perspective view of one of. the
Specification of Letters Patent. P t t 11, 1919, Application filed. October 14, 1918. Serial No. 258,110.
Removable driving bars 11 are received in the guides 4, the lower endsof said driving bars being adapted to rest upon the spikes as clearly shown in Fig. 3, while the upper ends of .the bars in question project from the upper ends of the guides in the downward paths of a plurality of hammer heads 12 mounted on longitudinal hammer handles 13 which are pivoted at 14 to the platform 3, the ivoted ends of the handles 13 being by pre erence mounted in slots 15 formed through said platform. By the means described below, the hammers are 11 so as to drive the spikes 8 into the ties '1, and since the hammer heads cannot descend to the maximum until thespike is totally driven, it is necessary to provide means for varying the throw of the ham mers proportionately withthe driving of the spikes. In other words, the throw of the hammer must be increased after each.
- form of a reciprocating platform as shown,
is mounted upon the platform 3, said actuator preferably resting on flanged rollers 17 and being held in engagement therewith by other rollers 18, both sets of rollers being mounted onsuitable brackets 19. The edges of the actuator or platform 16 are preferably bound with channel or angle iron as seen at 20 for engagement with the rollers 17 and 18 and to generally reinforce the member in question. The actuator 16 is formed with longitudinal slots 21 into which the upper ends of the guides 41 and the driving bars 11 project and through which said guides may be moved when raised, such raising being preferably done when the car is being drawn from one oint to another rather remote therefrom. 22 ar pivoted at one end to the handles 13 and at their other ends to the hammer actuator 16, and means are provided for reciprothe bars 11, thus forcing the spikes 8 into the ties.
The reciprocating means for the hammer 11m inks 70 swung around their pivots to drive the bars actuator 16, may be of any preferred construction, but for illustrative purposes, I have shown a pitinan 23 extending to said actuator from a crank pin 24 operated by a reducing gear 25 from a gas engine or the like 26 which is mounted upon the platform 3. The pitman 23 is formed of two sections 27 and 28 slidable relatively and is resisted in such sliding by rather stiif coiled springs 29. After the hammers strike the driving bars 11, the wrist pin 24: may still move to the limit of its stroke, since the springs 29 will then yield to allow such movement. As the spikes are driven, it will be obvious that the actuator 16 will be reciprocated a greater distancg before the springs come into play,
and upon-the final strokes, the springs in question need not operate.
In operation, the livheels 1 travel along the rails 2 and the car is stopped so that the spike guards i are properly located over each of the ties. The brakes of the car are then applied to hold the same against shifting, the driving bars 11 are removed, and the spikes 8 dropped into the guides 4 with their projecting heads 10 received in the slots 9 so as to prevent turningof said spikes during their descent. The driving bars 11 are now replaced and the hammer actuator 16 is set 'in motion by means of its driving mechanism, the'res ilt being that thesuccessiv'e blows delivered by the hammer heads 12 upon the driving bars 11, Will drive the spikes 8 in the ties 7 accurately and rapidly.
In the foregoing I have described and in the accompanying drawings illustrated one embodiment of my invention, and although the general arrangement shown anddescribed is preferable, it is to be understood that within the scope of the invention as claimed, numerous minor changes may Well be made.
I, claim:
v 1. In a railway spike driver'a car to travel along the railway rail, tubular guides depending from said car to receive the spikes and guide them into place, supporting means having openings slidably receiving the guides, said guides having longitudinal slots to receive the spike heads, said slots impart ing circumferential resiliency to said guides to hold them yieldably in said openings, removable driving bars in said guides and projecting from their upper ends, and mechanical hammers for driving said bars doivni'ardly to drive the spikes.
2, In a railavay spike driver, a car to travel along the railway rails, said car having a. platform, tubular guides depending from said platform to receive the spikes and guide them into place, removable driving bars in said guides and projecting from the upper ends thereof, a hammer actuator mounted for reciprocation on said platform, hammer handles pivoted to said platform and carrying hammer heads for driving said driving bars to force the spikes into the. ties, links pivoted atone end to said hammer actuator and at their other ends to said hammer handles, and means-for reciprocating said hammer actuator to operate the hammers.
3. In a railway spike driver, a car to travel along the railway rails, said car having a platform, tubular guides depending from said platform to receive the spikes and guide them into place. removable drivin bars in. said guides and projecting from the upper, ends thereof, a hammer actuator mounted.
for reciprocation bn said plat-form, hammer handles pivoted to said platform and carrying hammer heads for driving said driving bars to force the spikes into the ties, links pivoted at ne end to said hammer actuator and at their other ends to said hammer handles, and means for reciprocating said haminer actuator to operate the hammers and for increasing the stroke of saidactuator proportionately with the driving of the spikes.
I. In a. railway spike driver, a car to travel along the railway rails, said car having a platform, tubular guides depending from.
