Rapmq Patented Mar. 31, 1931 UNITED STATES max minute, or MUNICH, GERMANY METHOD OF AND MEAN FOR FASTENING DOWN RAILS Application filed July 25, 1929, Serial No. 381,005, and in Germany September 4, 1928.
The invention relates to a method of and means for fastening rails by means of plate springs which press down upon the foot of the rail.
15 It is now customary in rail fastenings of this kind to stress the springs by directly or indirectl'f pressing them down by screws, nailsand the like; or the springs are in the form of a wedge and are forced. by heavy blows underneath the holders which are secured to the sleeper. These methods have failed to produce a serviceable rail fastening on which reliance could be placed.
The method of the invention differs from the foregoing in that the springs are stressed by a screw-press or other tool independently of the rail fastening itself and they are thus held until the holders are applied or until the springs are in the proper positions relatively to the holders, whereupon the springs are released sufiicientl'y to allow them to press against the holders. The tool is then ,removed.
Various forms of the rail fastening according to the invention and of the tool employed for stressing the springs, are illustrated in the accompanying drawings, in which:
Figures 1 and 2 are respectively,,a crosssectional elevation and a plan of half of a.
Figure 66; being an end view on a larger scale of the key used therewith.

Figures 8 and 9 are respectively, a crosshalf a rail and of a fifth form of rail fastener Figures 11 and 12 are respectively, a crosssectional elevation and a plan of half a rail and of a sixth form of rail-fastener according to the invention.
Figure 13 is aside view of a part of a rail 58 and of a seventh form of rail-fastener according to the invention,
Figure 14 being a corresponding plan with the rail in section on XIV-XIV, Figure 13.
Figures 15 and 16 are side views of parts of rails and of two further forms of railfastener according to the invention.
Figures 17 and 18 show an end and side elevation'illustrating part of a rail in a chair fitted with plate springs and of one form of tool employed for stressing the plate springs, according to the invention.
All forms of the rail fastener illustrated, with the exception of that shown in Figure 10, have plate springs 1 of the triangular form shown in Figures 3 and 4, placed upon the foot 2 of the rail 3, so that the somewhat blunt apex of the triangular spring presses against the web 3 of the rail and the longest edge or the base rests upon the edge of the foot 2 of the rail.
In the forms shown in Figures 1 and 2, the base 4 of the chair or fastener is provided with a hook shaped rib 5. When the triangular spring 1 is not stressed, that is to say, before use, it is bow-shaped as indicated in Figure 4. It is first laid upon the foot of the rail and then stressed by means of a screwpress or tool such as that hereinafter described, that is to say, it is pressed down upon the foot 2 of the rail. A clip 6, which is Z-shaped in cross-section, is then inserted between the hook shaped rib 5 and the foot 2,
so that its lower flange 6a engages under the rib 5, and its upper flange 6b engagesover the stressed spring 1.
The clip 6 being now in position, the stressed spring is slightly released by the tool hereinafter described so that it presses against the upper flange 6b of the clip 6. .95 Thereupon the tool which has been employed for stressing the" spring is removed and the rail fastening is complete. The foot 2 of the rail is now gripped by the s ring 1 between the clip 6 and the base 4 o the chair, and
cannot be freed until suliicient pressure is applied to the spring 1 to release the pressure on the clip 6 to enable it to be withdrawn, thus necessitating a tool such as that hereinafter referred to.
The preferred form of tool for stressing the spring 1 illustrated in Figures 17 and 18, comprises a screw threaded spindle 7, which passes through an internally screw threaded boss or nut formed on a cross-head 8 and has its lower end connected to a U-shaped pressure member 10, so that it can rotate relatively to said member, but cannot move axially with respect thereto, for example, by means of a U-shaped locking pin 9 inserted in holes in the boss 10a of the pressure member and into a groove 11 in the end of the spindle 7. The hole 13 in the boss 10a has a spherical bottom and the end of the spindle 7 is correspondingly shaped. Anchoring members or gripper arms 14 are pivoted to the crosshead 8 by the pins 15. An operating lever 19 is mounted freely on the end of the spindle 7 and has a ratchet toothed clutch member 206 for co-operative engagement with a ratchet toothed clutch member 20a on the spindle 7.
The lever 19 is rigidly secured to the upper part 205 with which it can be rotated and is axially movable on the upper cylindrical part of screw spindle 7, so that when this is rotated to the left, the teeth of the clutch members 20a, 205 can move one on the other, the upper part 20?), moving upwards, whereas when rotated to the right, the lower part is taken round by the upper. The upward axial movement is limited by an enlargement 7a.
The operating lever 19 has a key 21, pivoted to it which can be placed in between the upper shoulder 7 a of the screw spindle 7, and the upper clutch member 201), so as to lock the lever to the spindle in order to enable the spindle to be unscrewed to remove the member 10 from the plate springs 1.
The tool is used in the following manner:
The screw spindle 7 is first unscrewed until it has reached its uppermost position, so that the gripper arms 14 are down in their lowermost position. The springs 1 havin been laid upon foot 2 of the rail, the U-shape pressure member 10 is lowered over the head of the rail 22' and the web 3 of the rail, so that the lower ends of the arms of the pressure member 10 reach the springs 1, thelower rounded ends of the arms 14 of the gripper passing over the adjacent portions 24a of the ribs 24 of the chair base plate 4. When they have passed the projections 24a on the ribs, the members 14 fall inwards, so that they engage below the head of the rail. The screw spindle 7 is then rotated by means of the operating lever 19, so that the gripper arms 14 firmly engage with or are anchored by the projections 24a and consequently the pressure member 10 is pressed against the springs 1, so that the latter are stressed or pressed fiat against the foot 2 of the rail and thereupon the means for locking the springs, for example, the above described clips 6, are placed in position. The key 21 is then inserted and the screw spindle 7 is unscrewed so that the springs 1 arch until they press against the key. The fastening of the rail is thus completed.
The springs 1 are released in similar manner.
The form illustrated in Figure 5 differs substantially from that illustrated in Figures 1 and 2, in that a rib 23 is provided 011 the base plate 4 between the clip 6 and the foot 2 of the rail. The rib 23 determines the p0sition of the rail and provides a good grip for the clip 6.
A particularly satisfactory form is that illustrated in Figure 6, wherein ribs 24 are provided on the chair base 4 on both sides of the foot of the rail, against which ribs the foot of the rail as well as the outer edges of the springs 1 can bear.
Each rib 24 is provided with a slot 25. Each spring 1 is pressed down by the tool hereinbefore described, flat upon the foot of the rail, whereupon the upper arm of an angular clip 26 is inserted into the slot 25, the end 26aof the clip 26 being slightly diverted upwardly and thickened. The uppermost point of the spring is then about 3 mm. lower than shown in Figure 6. Immediately the spring is released sufiiciently to allow it to press against the clip 26, the diverted end 26a of the clip 26 prevents the latter from retiring through the slot. The downwardly pointing arm 26b of the clip 26 presses against the rib 24 and also upon the base 4 and thus provides a grip for the clip.
As will be seen from Figure 7, the ends 1a of each spring 1 may be turned down so that they curve around the adjacent rib 24. The spring is thus prevented from moving sideways, although there is no such movement in practice because the spring is so firmly held. For the same purpose, namely, to prevent lateral movement, the support for the end of the clip 26 which engages over the spring may be slightly hollow, that is, shaped to conform to and snugly fit the arched upper point of the spring.
In the forms shown in Figures 8 and 9, ribs 27 are provided onthe chair base plate 4,
near the foot of the rail, and each of these ribs is provided directly above the base with a slot 28. Into this slot is inserted the lower arm 29?) of a substantially U-shaped clip 29, the upper arm 29a lying upon the spring 1.
The form shown in Figure 10 is merely to demonstrate that it is possible to dispose the spring directly on the chair base plate, and not on the foot of the rail as in the forms previously described, that is to say, to place it outside the rib 30 of the base 4. The clip 1 CPI or plate 31, which holds the spring 1 is passed through a slot 32 in the rib 30, so that the outer end of the plate 31 is pressed by the spring 1 upwards, whereas the inner end 31a is pressed downwards upon the foot of the rail.
In the form shown in Figures 11 and 12, a hook-shaped clamping plate or clip 33 is secured to the wooden cross tie or sleeper 36 by means of the screw 34. A tubular extension 35 of the hooked plate or clip 33 pene- In the form shown in Figures 13 and 14.
after the spring 1, having been stressed by means of the tool hereinbefore described, the nails 38 are driven in and the spring is allowed to press against the heads of the nails and the foot of the rail by loosening the tool. It will be obvious that screws may be employed in place of the nails 38.
In the forms shown in Figures 15 and 16, only one nail or screw 38 is used respectively for each spring 1. Thus, unlike the construction according to Figures 13 and 14, the spring 1 is in each case inserted with the arch upwards.
In all the forms hereinbefore described, a thin layer of wood or packing strip 39 is inserted in the usual manner under the foot of the rail.
