MACHINE FOR REMOVING ANI) REPLACING METAL PARTS OF TRAIN-PIPE COUPLINGS.

Application filed October 23, 1916.

To all whom it may concern:

Be it known that we, WILLIAM D. FAID- LEY, Jr., residing at Clifton Forge, Alle ghany county, Virginia, J oI-IN W. MORRIS, residing at Iron Gate, Alleghany county, Virginia, and SAMUEL A. PATTERSON, residing at Clifton Forge, Allegha'ny county, Virginia, citizens of the United States, have invented certain new and useful Improvements in Machines for Removing and Replacing Metal Parts of Train-Pipe Couplings, of which the following is a specification.

This invention relates to mechanism for detaching the metal parts of worn out train pipe couplings, especially the coupling heads, nipples and clamping bands carried by the opposite ends of the hose sections comprising such train pipe or air brake couplings, and for applying such metal parts to new hose sections. Heretofore when a hose section has become so worn as to be of no further use, the whole coupling has been discarded, although the metal coupling head, nipple and clamping bands are by no means It is the aim of this invention to provide a machine for removing such metal parts from the old hose sections and for attaching them to new hose sections so that they may be again utilized.

The coupling head and nipple are fastened to the opposite ends of the hose section by clamping bands or rings having spaced outwardly turned flanges at their ends se-' cured together by bolts bridging the space between said flanges. These clamping bands or rings must be removed before the coupling head and nipple can be separated from the end portions of the hose section, and the machine embodying the invention is equipped with means for doing this as the first step in the removal of the metal parts ofv the coupling. Means are also provided for holding the hose section while the coupling head and nipple are either withdrawn therefrom or applied thereto.

- The invention will he first hereinafter described in connection with the accompanying drawings, which constitute part of this specification, and then more specifically delined at the end. of the description.

A table 1, which carries certain parts of the machine, is mounted upon suitable supports 2 and 3 at opposite ends thereof, the supports 2 at one end extending up through the table, as at 4, and supporting the pivot 5 of a lever 6 for operating the reciprocating knife 7 which is used for cuttmg the bolts 8 holding the clamping bands 9 around the hose sections. Said lever 6 is operated by a bell-crank lever 8 pivoted at 9 between a pair of longitudinal bars 10 arrangedbelowthe table 1, one end of said bell crank lever being connected to the lever 6 by a pitman 11 while the other end of said lever 8 is connected to the piston rod 12 of a compressed air cylinder 13 located on a platform 14 at the base of the table. Any suitable means (not shown) may be employed for controlling the reciprocating movement of the piston rod 12 for moving the knife 7 through the instrumentality of the bell crank lever 8, pitman 11 and lever 6.

At one side of the knife 7 there is a depending guide 15 working in a slot 16 in the table. Another slot 17 enters from one side of thetable and terminates adjacent the knife, and into this slot 17 the hose 52 is introduced, as shown in Fig. 5, when the bolt 8' is to be cut. -When the hose is in position in the slot 17 as shown in this figure, the clamping band 9 is arranged above the top surface of the table and the middle portion of the bolt is disposed below the knife, so

that when said knife descends it will cut through said middle portion of the bolt thus releasing the end portions or flanges 18 of the clamping band from one another.

During the cutting operation the bolt 8 is supported upon a'beveled lug 19 projecting above the top surface of the table 1 and having a vertical face 20 in vertical alinement with the flat side of the knife 7. The opposite face of the lug 19 is inclined, as at 21, Fig. 6. Thebolt 8 also rests upon a beveled laterally extending lug 22 on a sliding member 23 fitted in a recess in the table 1 and normally held in the position shown in Figs. 5 and 6 by a spring 24. lVhen the knife descends its beveled edge, after passing through the bolt enters between the lugs 19 and 22 and forces the sliding member 23 away from the fixed lug 21, thereby spreading the flanges 18 on the clamping ring 9 to some extent. As the knife completes its downward stroke the head 25 comes in contact with the flanges 18 and forces them still farther apart as they are moved down along the inclined face 21 of the lug 19 and the correspondingly inclined opposite face 26 of the lug 22. After this operation the clamping band 9' will be loose enoug to be readily removed when the arranged substantially coupling head and nipple are taken off by the mechanism presently described. Afterbeing removed the clamping band is in condition to be used again for holding a nipple or coupling head on a new hose section. Said hose section is then placed across the stationary jaw 27 of a holding clamp arranged on the table 1, and the supplemental movable member 28 of said clamp is forced down upon .it by means of compressed air apparatus including a cylinder 29 supported on the back of the machine, a piston rod 30 working in said cylinder, an intermediately pivoted lever 31 connected at one end to said piston rod, and a link 32 connected to the other end of the lever 31 and to the movable jaw 28. It will be understood that any suitable means (not shown) may be employed for controlling this compressed air apparatus. At one side of the clamping jaws 27 and 28 a sliding block 33 is mounted onguides 34 to be moved toward and away from said clamping jaws. The movement of said block 33 is effected by a lever 35 pivoted at 36 between the bars 10, a link 37 connected at one end to the lever 35, another lever 38 pivoted at 39 between the bars 10 and connected to the other end of the link 37, another link 40 connected at one end to the lever 38, another lever 41 pivoted at 42 be tween the bars 10 and connected to the other end of the link 40, and a piston rod 43 work ing in a compressed air cylinder 44 and connected to the lever 41, as clearly illustrated in Fig. 1. g 7

At the other side of the clamping jaws 27 and 28 a block 45 is mounted to slide on guides 46 toward and away from said jaws, and said block 45 is reciprocated by means of 10 a lever 47 pivoted at 48 between the bars 10, and a link 49 connected at one end to the lever 47 and at the other end'to the lever, 38. From the arrangement of levers shown and described, it will movement of the piston rod 43 will cause the blocks 33 and 45 to move in opposite directions away from the clamping jaws 27 and 28, while the reverse movement of the piston rod 43 will advance the blocks 33 and 45 toward said clamping jaws.

As illustrated in Figs. 1, 7 and 8 the block 45 carries a tool 50 adapted to enter the nipple 51 on the adjacent end of the hose section 52 on the advance movement of said block 45. Said tool 50 is provided with an expanding clutch comprising two members 53 hinged together at 54 and adapted to project through slots 55 in the tool, as shown in V Fig. 7, for engaging the inner end of the 1 nipple 51 so that when the block 45 is moved away from the clamping jaws 27 and 28, the nipple will be withdrawn from the hose section 52 which is clamped between said jaws.

The tWO members 53' of the clutch are-im be seen that the outward 11 mally held folded, as

' hand lever 58 pivoted at 59 on the tool 50 and having its inner end 60 working in the slot 61 in anextension 62 of the wedge 57 which is mounted to slide inside of the tool 50. A coiled spring 63 is arranged about the extension 62 of the wedge 57 and abuts at opposite ends against a shoulder 64 on said wedge and a shoulder 65, on the tool for assisting in the advance of the wedge between the members of the clutch at the proper time. The members 53 of the clutch have teeth 66 on their outer edges for gripping the inner end of the nipple 51, and said members also have lugs 67 on their inner edges for limiting the outward movement thereof by engaging the ends of the slots 55, as shown in Fig. 7. The tool 50 may have longitudinally extending grooves 68 in its side to aiford free escape of air when said tool is thrust into the nipple. 7

As shown in Figs. 1, 11, 12 and 13, the block 33 has detachably connected thereto a tool 69 mounted upon rollers 70 running on the top surface of the table 1. This tool 69 has a pair of upwardly projecting lugs 71 and 72 between which the coupling head 73 may be inserted so that when the block 33 is moved away from the clamping jaws 27 and 28, said coupling head will be withdrawn from the hose section which is gripped between said jaws. In order to adapt the tool 69 to fit difierent sizes of conphng heads, the lug 72 is made removable and reversible so as to vary the distance be tween it and the fixed lug 71. To this end the lug 72 is provided with a laterally eX- tending portion 74 which with the reduced base 75 of the lug fits a slot 76 in the tool 69. The lug 72 also has a threaded portion 77 to pass through the slot 76 and receive a nut 78 for securing the lug in either one of its positions. It will be readily understood that when the nut 78 is loosened on the threaded portion 77, the lug maybe raised until its reduced base 75 and lateral projection 74 are removed from the slot7 6, and that when the lug is turned around and its base 75 is seated in the slot with the projection 74 at the opposite side, the distance between the lugs 71 and 72 will be changed. Both of the lugs 71 and 72 may be provided with curved portions or recesses, as indicated at 79, in Fi 13, to prevent the coupling heads from being injured.

One of the tools illustrated in Fig. 14 is carried by each of the reciprocating blocks 33v and 45, as shown in Fig. 1. Jach of these eals; sameness .aleaf. s2. tasteless to. the

block, a hinged portion 81 and depending fingers 83 at the free end of said hinged portion. The hinged portion 81 is of angular formation so as to raise it above the tools 50 and, 69, and is notched at 81 to avoid inter? tering with the hand lever 58. The fingers 83 are designed to embrace the hose section 52 and engage the clamping bands 9, which have been loosened as already explained, whereby said clamping bands are removed from the hose section simultaneously with the removal of the nipple and coupling head when the blocks 33 and 45 are moved away from each other. The fingers 83 may be adjusted, as suggested at 84, for fitting different sizes of hose sections.

As illustrated in Figs. 15, 16 and 17, auxiliary hose gripping means may be provided for insuring the proper holding of hose sections which have become so worn out in the middle as to be unfit for being firmly gripped between the clamping jaws 27 and 28. This auxiliary gripping means may also be used for holding separate end portions of hose, as where the hose sections have become entirely worn through at the middle. This auxiliary gripping means comprises a pair of claws arranged at each side of the clamping jaws 27 and 28. One claw 85 of each pair is stationary, while the other claws 86 are mounted to slide across the table 1 in guides 87. The movable claws 86 of each pair may be moved in unison by means of eccentrics 88 on a countershaft 89 journaled in brackets 90 on the back of the machine and rotated by means of an arm 91, a link 92 connected at one end to said arm, a lever 93 connected to the other end of the link and intermediately pivoted at 94 to a bracket 95 depending from the table 1, a link 96 connected to the other end of the lever 93, a bell crank lever 97 connected to the link 96 and pivoted at 98 to an extension of the pivot 39 for the lever 38, and a link 99 connecting the other end of the bell crank lever 97 with the lever 41 operated by the piston rod 43 in the cylinder 44. It will thus be seen that during the movement of the blocks 33 and 45 toward the clamping jaws 27 and 28, the movable claws 86 will be advanced toward the fixed claws 85 for gripping the end portions of the hose section.

lVhen the hose sections are short, the tool 100, Fig. 18, may be used instead of the claws 85 and 86. This tool 100 has a base 101 adapted to in the guides 87, so that said tool may be placed at the side of the clamping jaws 27 and 28 adjacent the nipple removing tool. Each tool 100 carries a U- shaped blade 102 adapted to be inserted between the end of the hose section and the wrench engaging flange 80 on the nipple and when so arranged will positively hold the hose section while the nipple is'being withdra -e, It v llbe under ced. f. course,

that the fiatface of the blade 102 is engaged with the end of the hose section.

In Fig. 19 is illustrated a tool 103 adapted to be attached to the'block 33 in place of the tool 69 when it is desired to attach an air brake coupling head to a new hose section. The tool 10% illustrated in Fig. 20 is designed for attachment to the block 33 when a steam pipe coupling head is to be at tached to a new hose section. The tool 50 may be used for attaching nipples to new hose sections as well as for removing nipples from old hose sections as already described, the operation of attaching the nipples being simply the reverse of that for removing them. The new hose section to which nipples and coupling heads are to be attool 110 shown in Figs. 21 and 21 fiat on the sides and is especially from the outside of the 'is in the nipple.

tached may be held between the clamping jaws 27 and 28 in the same manner as the old hose section when the metal parts are removed therefrom.

The modified form of nipple-engaging differs from the tool 50, Figs. 7 and 8 in having one fixed clutch tooth 111 and one movable clutch tooth 112, whereas the tool 50 has both clutch teeth movable. The movable clutch tooth 112 is pivoted at 113 to the body of the tool 110 and is operated by means of a hand lever 114 pivoted at 115 and normally pressed by a spring 116. The tool 110 is adapted for use with crushed or mashed nipples.
