3 Claims.` (Cl. 78-50) This invention is a rail binding apparatus which is particularly intended to apply stud terminal bonds to holes in railroad rails by means road rail to be bonded and having a depending end 2 in which a bore 3 is formed with its axis directed toward the side of the rail to be bonded. A cylinder 4 is threaded into this bore and has portions Ia and t projecting beyond both ends' of the latter.

A piston 5 is reciprocatively arranged in the I cylinder 4, and an inwardly ilanged nut 6, which is screwed onto the end 4 oi' the cylinder, constitutes a means for mounting a tool`guide 'I in Y which an impacting tool 9 is reciprocatively ar-4 ranged, a threaded hole 9 in the piston 5 func-l tioning in conjunction with a threaded stud'lIl' to provide a means for interfastening the piston and the tool. l

The guide I and tool 8 are not more specifically described because they do not form a part .of the present invention, it being suicient to say that the tool hits the head of the usual type of bond applied to a rail headso as to expand the terminal stud of the bond. It should be noted that the guide l has an outwardly anged end I1- which is, engaged by the inward ange of the r the nut 6. The firearm I4 is part of a small caliber rie suitably adapted for the purpose and which res blank cartridges into the barrel i3.

In the operation of this gun, a blankl cartridge is placed in the firing chamber of the ilrearm I4 and fired, the force of the explosive going through the bored screw I2 from the barrel I9, thus driving the piston 5 forwardly and causing the impacting tool 9 to strike against the terminal of the bond being applied to the rail. Means are provided for resilientiy urging the piston 5 away from the rail, thisbeinga spring I1.

A bracket I8 slidably mounts the frame I and includes a depending member I9 for engaging the other side of the rail from that to which the bond is being applied. This bracket also has arms 20 that oppositely extend in the direction of the rail, and upstanding lugs I5* between which the frame slides transversely of the bracket.

A depending part 2| is adjustably slidably iixed to the frame I so as to oppose the member I9.`

This part slides on the frame I and is fixed by means of a screw 22 which bears againsta plate 23 transversely ixed to its upper end. A spring 24 is arranged between the part 2l and the member I9 and is retained in position by a bolt 25 which extendsbetween these two. Adjustment of this bolt permits some variation of the resilient characteristics of this spring.

Vertically adjustable elements 26 depend from the ends ofthe arms 20 so as to contact the top of the rail. These elements are here screws, but may be substituted by other easily adjusted devices.

In use, the frame I is transversely arranged over the rail to be bonded so that the elements 26 contact its topand so that the depending member I9 is against the side of the rail which is opposite froni that to be bonded. Adjustment of the elements 26 provides for both vertical and angular movements,whi1e adjustment of the screw 22 serves to bring the guide I against the terminal of the bond. When the gun is red toward the side of the rail inthe manner previously described, the recoil is transmitted through the frame I tothe opposite side of the rail by way of the spring 24. It is apparent that the part 2|, spring 24 and depending member I9 cooperatively function as a shock absorber. l

Although a specific example ofthis invention is described in accordance with the patent statutes, its scope vis not to be Hunted except as dened by thefollowing claims.

We claim:

1. Rail bonding apparatusl including a frame constructed to transversely bridge the rail to be bonded, a gun carried by one end of said frame so as to re towards one side of said rail, a bracket slidably mounting said frame and including a. depending member for engaging the other side of said rail, and arms that oppositely extend in the direction o f said rail, a depending part adjustably slidably xed to the other end of said frame and opposing said member, spring means interconnecting said part and said member, and vertically adjustable elements depending from the ends of said arms so as to Contact the* top of said rail.

2. Rail bonding apparatus including a frame constructed to transversely bridge the rail to be bonded and having a depending end in which a bore is formed with its axis directed towards the side of said rail, a cylinder xcd in said bore and having portions projecting beyond both ends thereof, a piston in' said cylinder, means on the end of said cylinder towards said rail for mounting a tool guide, means for interiastening said piston and a tool reciprocating in said guide, means for fastening the barrel of a firearm to the end of said cylinder that is remote from said rail, and means for resiliently urging said piston away from said rail.

3. Rail bonding apparatus including arframe constructed to transversely bridge the rail to be bonded and having a depending end in which a bore is formed with its axis directed towards the Y means for fastening the barrel of a'ilrearm to the end of said cylinder that is remote from said rail, means for resiliently urging said piston away from said rail, a bracket slidably mounting said frame and including a depending member for,

engaging the other side of said rail and arms that oppositely extend in the direction of said rail, a depending part adjustably slidably fixed to said frame and opposing said member, spring means interconnecting said part and said memberand vertically adjustable elements depending from the ends of said arms ,so as to contact the top of said rail.
