2 SHEETS-SHEET 2;
Wane/sow L, M which are supported by the rings J, J and to which are connected flexible hose L M which pass out through the lower end of the cylinder A around wheels N and over pulleys O, the ends being connected to a rotary valve P similar to the valve G. The valve P is connected to the main supply pipe H by a branch pipe Q and it will be seen that the fluid can he allowed to enter the cylinder C through. either of the ports in a similar manner as it enters the cylinder B and when the port M is opened the plunger K will be forced to the top of the cylinder the liuid within the cylinder exhausting throu h the port L and when fluid is forced into tie cylinder through the port L the plunger will be forced downwardly so as to strike a blow against the upper end of the cutting tool 1. Connected to the frame 0 of the pulleys O is a coil spring R. which is connected to an eye bolt secured in the flanges of the cylinders A and B so that as the cylinder C is moved up and down .in the cylinder B the flexible hose will be drawn tight at all times whereby all danger of the hose becoming jammed within the cylinder A is prevented.
The lower end of the cylinder A is provided with an exterior flange to which is connected a handle S for guiding the machine and the ldwer end of the cutting tool 1 is preferably formed concaved as clearly shown and adapted to be placed over a stay bolt by means of the controlling fluid in the cylinder B which will raise or lower the cylinder C so that by operating the valve G, the cutting tool can be forced up against the stay bolt to be cut and held in that position and then by operating the valve P the,
plunger K can be operated so as to cause the same to strike the cutting tool.
From the foregoing description, it will be seen that I have provided a stay bolt breaking machine which will operate upon a stay bolt so as to break or cut the same, It will also be seen that I have provided a machine i with novel means for raising and lowering the cutting tool so that it can be placed in position against the said stay bolt by simply operating the valve. \Vhat I claim is 1. In a machine of the character described, the combination with a pair of connected cylinders disposed end to end and one above the other, and adapted to be supported by a movable trolley, of an inner cylinder mounted in the said first mentioned cylinders, a p unger in the inner cylinder a cutting tool movably mounted in the lower end of the inner cylinder, ports formed in the respective cylinders adjacent their ends, l'luid supply pipes connected to said ports, and valves controlling the supply of said fluid to the l'QSPQCtlYG cylinders to position the inner cylinder and to operate the plunger.
In a machine of the kind. described, the combination with a pair of connected cylin ders disposed end to end, and located one almvethe other and adapted to be supported by a movable trolley, of a cylinder slidably mounted. within the upper cydnder carrying a cutting tool carried by the inner cylinder and. extending out through the lower cylinder, at plunger slid-ably mounted within the inner cylinder, ports communicating with the respective cylinders, pipes connected to said ports, flexible pipes connected to the pipes carried by the inner cylinder and passing over pulleys, a coil spring supporting said pulleys and a valve connected to the ends of said flexible pipes, for the purpose described.
3. A machineof the kind described cornprising a pair of connected cylinders dis posed end to end, and one above the other, of a cylinder arranged within the said first mentioned cylinders, a cutting tool carried by the inner cylinder extending within the same, a plunger adapted to engage said cutting tool, ports coinnninicating with the outer cylinder, pipes connecting said ports to a rotary valve, ports communicating with the inner cylinder, pipes connected to said ports, flexible pipes connected to said pipes having their ends connected to a retary valve, said flexible pipes passing over spring actuated pulleys and a. main supply pipe connected to said valve, for the purpose described. lljilfiltY LOUIS HAHN.
