MACHINE ron RE OVING Ann Application filed December 27, 1921.

Virginia, citizens of the United States, have invented certain new and usefullmprovementsin Machines for Removin and Replacing Metal Parts of Train-Fipe Couplings, of which the following is a soecification.

This invention relates to machines for as sembling train pipe couplings and for removing the metal parts thereof from worn or weak hose. The present invention relates particularly to the machine for which Letters-Patent No. 1,252,676, were granted to us January 8, 1918, the objects of the invention being to provide simple and efficient means for controlling and expediting the operation of the machine, to provide means for supporting the hose and preventing buckling of the same while the metal partsare being assembled therewith, to provide means for compressing the clamps about the hose, and to improve generally the construc- -'tion and arrangement of the parts of the machine to the end that the efficiency and durability thereof may be increased without any increase in the cost of production or maintenance.

The invention is illustrated in the accompanying drawings and consists in certain novel features which will be hereinafterfirst fully described and then particularly point" ed out in the appended claims.

In thedrawings, 1 Fig. 1 is a-front side elevation of a machine embodying the present improvements. Fig. 2 is a plan view of the same, one clamp-puller being omitted. Fig. 3 is a longitudinal section.

F 1g. 19 is a View similar to Fig. 18 but showing thejaws ina different position.

Fig. 20 is a side View showing another arrangement of the jaws.

Fig. 21 is a plan View of the arrangement shown in Fig. 20. I The bed or main frame 1 of the machine is supported by feet 2 at its ends. On the top of the bed, at one end thereof, is'a fixed of the mechanism knife 3 and cooperating with said knife-is" a rocking or oscillating knife 1 which is carried by the upper end of a lever 5, said lever being fulcrumed in suitable bearings 6 on the top of the bed and extending downwardly from the bearings. The lower end of the lever 5 is pivotally connected to'the outer end of a piston rod 7 which extends from a piston 8 fitted in a cylinder 9, said cylinder being supported in any convenient or preferredmanner at the bottom of the bed. The piston is caused to reciprocate in the cylinder, preferably, by compressed air which is admitted to the cylinder at the ends thereof through branch feed pipes 10 which lead toand discharge into the opposite ends of the cylinder from a controlling valve-11 It will be readily understood that the valve 11is set to admit the motor fluid to one end of the cylinder and simultaneously permit it to exhaust from a port 11 from the opposite end, and the'lever 5 will be rocked in one or the other direction according to the direction of flow of the fluid to the cylinder and I the resultant movement of the piston. Normally, the lever is in the position which holds the knife 4 raised and: the piston is? at or near the outer end of the cylinder. When the bolt in a compression or clamping band on a train-pipe coupling, is to be cut, it is held manually upon the knife and the; ;le-ver 5 rocked so that the knite l is forced down upon the bolt which is thenquickly cut through by the two knives.

The compressedan' or other motrve fluid ,iscarried to the valve 11 by a supply pipe 12: which. is mounted: on the front of :the bed and has .a branch .13 extending transversely through the bed e'an'dl communicating I through :a coupling 14 with a main. supply pipe 15. Pipes 16and 1 .6 'l'eaidirom: aiifour way valve 171cm "the backxo'f the bed to carry the motive fluid to other points of use. The stem oFfathewalve 1 .1 is equipped 'at'its front end with an angle leveiysthe upstanding arm 1810f which has one end of a. spring 2(9 attached thereto, the opposite aendf'of the to normal position.

spring being attached to lined point on the bed. The lateral arm 19* oi the angle 1 lever is connected by a link 21 "withatreadle common t0 a larger cylinder 25., the purpose of which willhereinatter appear. The saidcylinder 25 :isconstructed with a foot constituting an intermediate support 1 for the 1 entire machine.

Thesflattop or table 2:? of the bedis con"- struoted with longitudinal slots 28 at or near its opposite ends and is so formed as tojprovide the longitudinal ways or guides 29' at the-opposite sides of the slots. 7 Carriers 3t) are-slidably-fitted to the ways-.29 v

one being equipped with means for supportmg and securing. the tram-p pe coupler l1ead.,'a-n.drtl1e other being. provided with a pin; or similar device. for supporting the nippie-which, in actual practice, forms the connection between the train line and the hose ofthe-coupli-ng; Upon each carrier there 1s also mounted a hose-cl amp puller- 31. lithinfthe bed there-:arepivotall y mounted the rocking'arms or levers-32, 33, each of which hasits upper end extended'throu'gl'i' one of the slots 28--and joined to the adjacent carrier by a pin and slot'connection, as shown tit--34,- the lower end of the lever'3'3 being connected with a. piston rod-35 in a similar mannenasshown at-3'6; A link 37 has one end pivoted to the lever 33-above the ful- The inner end of the cylinder, 9' is closed by a head 241 which is crum thereof and its opposite endpivoted to lever '32 below the *tulcrum Kthereofi, the result of such arrangement being that the levers will be caused to rock simultaneously but in opposite directions and the carriers,

consequently will approach or recede. The

piston rod 35 extends from the piston 88 the cylinder Q ffland the movement of said piston obviously actuates the lever 38, the motion being transmitted'through the link37 to the lever 32. Thepiston 38,

is driven by compressed iairadmitted tothe cylinder 25', at the ends; \t'hereot "through branch :teed pipes 39' which are connected by a controlling valve, 40 which, inturn, iscon' nected with the supply pipe 12 through :a'

nipple orcoup'ling 41, the easi-ngof theyalv'e 40 being constructed with an eX-lraust :port 40 which communicates with one or the other pipe 39 .accordin'gto the position. of

the valve. V v

A lever or handle 42 is -pro-vided to pen mit the operator 't'o easily setthe "valve-40" and control the direction of movement of the piston 38; The piston rod 35 extends axially througha bumper box 43 which is, preferably, formed integral with a foot 2', the outer, "end of the box beingopen and the inner end 'thereoi being closed: except for the bearing org'uide inwhichthe piston rodslides. The outer extremity efthe piston rod is threaded and astop collar-orabutment 4:4 is adjnstably mounted thereon, spring 4'5- bei'ng coiledwaround the piston rod between the abutment and-the :i nner closed end of the box. Obviously, the tension. of the spring may be regulate d'by' adlUU jus'ting the .stopcollar longitudinally of the a piston re d. Then the rodmoves: outw ardly, the springeXpands-"but when the rod moves inwardly "the-spring is com-pressed and, conse piently,,- eu'shlions the. return stroke and prevents .forclble cont-actv between the lever 32 or the lever 33 and the-bed at-the end of the stroke and takes upthe shock when the fittingsare pulled out oat old hose.

An elastic buffer blo'ck 4E6 on the opposite end, of the bed performs a like function for the lever 5. .A 'coye'r 4:7 is secured ever the open outer end of thebumpeubox and a tender. bar -48 pro ifects tram said" cover. When the a piston rod-v is at the iouter limit of its move-menhfi-t will be under t l1efender bar 48 and will be protected: thereby against,

Each carrier 30-has a pair of lugs 49 on its top between which the hose=clamp; pul-ler isv pivoted, and stop ,pins 50 are inserted through the lugs to support;the-, puflleiis in inoperative position. The. pullers asiwi-ll be I readily understood from the drawings each consists of a pivoted shank or arm and an inverted yoke or fork at the free end of the shank to span the hose. The yoke preferably consists of two inverted L-shapedmembers 51 having their cross arms overlapped on the free end of the shank and secured thereto by a bolt 53, the bolt passing through slots51 in said cross arms whereby the yokes may be adjusted to the diameter of the hose in an obvious manner.

One carrier has secured to its inner end a block 54 which constitutes a holder for the train-pipe-coupler head and has formed in its upper side a recess 55 which varies in form accordingly as it. is intended to receive the air-line head, the steam-line head, or the signal-line head. The coupler-head may be helddown in the recess in any convenient or preferred manner, and in Figs. 7 and 8 we have shown a latch bar 56 pivoted for horizontal movement at one end on top of the holder in-position to extend across the recess and have its free end engaged under a keeper 57 secured rigidly on the top of the holder block. In Figs. .10 and 11, we have shown a bar 58 held atone end by a headed stud 59 and constructed at its opposite end with a notch 60 to receive the upper end of a threaded pin 61 mounted on the side of the holder block. A hand wheel 62 is fitted on the upper eXtremit-yot the pin 61 and is turned home against the forked or notched end of the bar clamp the. same across the coupler head.

The carrier at the opposite end of the machine carries a nipple-stripper which is best shown in Fig. 9 and comprises a base 63 se cured firmly t0 the carrier and a part 64 of circular cross-section which projects horizontally from the base and is adapted to enter the nipple or fitting in the end of the hose remote from the coupler head. The part 64 is tubular as clearly shown and its free end is tapered, as at 65, whereby it may more readily enter the nipple, and within the tubular member, immediately adjacent the tapered free end thereof, is pivotally secured the stripper dog 66 which extends longitudinally of the tube away from the free end of the same. 1 This dog is adapted to project, atitsfree end, through the longitudinal slot 67 in the tube.64 and a stop. lug 68 is formed on the pivoted end of the dog to engage against the adjacent end wall of the slot and thereby limit the outward movement of the free end of the dog,the said free end of the dog being given a clawlike form, as shown at 69. so that it may readilyengage the end of the nipple or fitting. It will be understood that the device is pushed through the nipple or fittinguntil the dog clears the inner end thereof whereupon the dog isswung outwardly so that its claw or free end will engage the end of the nipple after which the puller is drawn longitudinally so that the nipple will be stripped from the hose. into the nipple-engaging position, we provide the plunger 70 within the tubular member 64 and the head 71 of this plunger has a beveled end or side upon which the dog rests. Movement of the plunger toward the dog will obviously raise the latter so that it will project through the tube 64 and engage the nipple while movement of the plunger in the opposite direction will permit the dog to withdraw by gravity. To effect movement of the plunger, we provide a lever handle 72 which is mounted in and projects upwardly from the base 63 and has its lower end engaged in an opening 73 in the plunger so that as said end of the handle is rocked iuone or the other direction To swing the dog.

the plunger will be slid in the same direction. A spring 74 is coiled around the plunger between a stop ring 75 in the tube and an abutment shoulder 7 6 on the plunger, the spring holding theplunger head '71 in engagement with the dog 66' and the stop ring being slipped into the tube and held by a set screw so that it may be adjusted to regulate the tension of the spring as may be desired. In assembling a nipple with a hose, the dog 66 is not necessary and the holder 77. shown in Fig. 12. may be employed, this holder being also somewhat shorter than the nipple extractor.

The holder 77 is carried by a base 78 the end of which presents an abutment which receives the thrustof the fitting due to the resistance offered. by the hose. The holder is circular in cross section and is constructed with longitudinal grooves or slots 110 to accommodate spring fingers 111 which are adapted to bind against the inner circumferential wall of the fitting and thereby firmly hold the same, the springs being held in place bv having one end. with the end of the holder. fitted snugly in a socket in the end of the base. The end of the hose in which the nipple or fitting is to be inserted is not always in exact axial alinement with the holder and we provide means for adjusting the holder to meet the conditions. The base 78 is pivoted to the carrier 30 and may move pivotally as it is over a slot 28 in "the top of the bed. A wedge 112 is arranged between the back of the base 78 and the opposed face ofthe carriage, and is constructed with an overhanging lip 113. A set screw 114 is mounted in the lip 113 and adapted to engage in a threaded socket in the base, washers 115 being fitted a ound the screw between the baseand the lip, as shown. The base is adjusted pivotally to permit the holder to properly engage the hose after which the wedge is forced be tween the base and. the carriage. The proper number of washers are then inserted to maintain the distance between the base and the hp 113 whereupon the screw 114 is sides of the clamp 79.;are guides83 between which plays the arm 8 flwhich carries ,2 the.

' clamp 81 and is in turn carriedbythe upperend of .a piston rod '85 rising .;fro1n,.a

"It the fluid be withdrawmgravity will cause the piston and the clamp to drop so thatthe hose will be heldpanjd if "fluid'be admitted above the piston" the hose will be'firmly-secured. When new fittings areto be assembled wi'th ahose, the corrugated-working "faces of the clamps 79 and 81 are-rendered inoperative by employing auxiliary'jaws to support the hose without pinching it-an'd in such a manner that it may remaln fully distended. The upper auxiliary'jaw 91 con sists of an elongated block ha'vingalongitudinalgroove92 in its lower side tofit over the hose, while on the upper side of the block are corrugations 98 which interengage with the corrugations onthe clamp 81 and adjacent the ends of the block overhangingilugs' 9 1 risetherefrom tofit around the side edges of the clamp 81, set screws 95' being mounted'in the upperends of the lugs to bind upon the clamp and I secure the auxiliary aw firmly v thereto.

Formers 107 are provided 01111 1 6 jaws 102 and arev removable so that the securing bolts may be engaged through openings 102 ad jacent either side ozt-the jaw whereby the formers may. be; adjusted to hose of different lengths. Obviously, by turning the hand wheels 10.6 the iaws 102 may bemade. ;t o;.recede orto approach so that the formerswill embrace the hose clamp. (hen the hose clamps are stripped from; the;hose,-; theyare frequently distorted and pl'llgllSlZgbk? reshaped before being applied to a newhose. fInour present machine, the hose clamps are ,-r,eshaped upon the hose :so that lar very ma- Jul)- terial saving-of time is efiected, an d, by

properly .manipulat-ing the screws, the clamps will be supported in proper-relation tothe hose while the fittingsiare being forced into the same, and are prevented fromspreading while the closing bolts are being inserted and secured.

' Motors maybe. substituted for :the hand'wheels 106. These motors may'be of any preferred construction I and are mounted on the-back of thebed, beingfed by. a pipe I 1.16 coupled directly to the. main supply pipe 15, as shown in Figs; 15 and 16. -Ea'ch motor has a stem 117 extending from its controlling valve, which stem is engaged with the u'p per end of a crank arm 118 on the rear end of a rock shaft 119'journalledfin and; eX-' tending through the bed of themachi-ne. 'On the front end of each rock shaft is a handle "120 whereby the shaft may beset :-to .start or stop the adjacent motor.

In striping ahose of its fittings, the

hose is secured'betweenthe clamps"79uand 61 and the carriers 30 are moved inwardly so that the nipple-puller will be engaged in the nipple and the coupler-head secured in the holder as hereinbefore set forth. clamp pullers are then engaged over the ends of the hose immediately behind the clamps, after which the piston 38 is caused to travel in the proper direction to effect outward travel of the carriers whereby the coupler head, the nipple, and the clamps will be quickly drawn from the hose. In assem bling the fittings with a new hose, the hose is placed between the jaws9l and 96 with the hose clamps around its ends. The aws 102 are then moved inwardly so that the formers will embrace said clamps and support them in proper angular relation to the hose, after which the carriers are moved inwardly so that the head and nipple carried by them will be forced into the respective ends of the hose. 1 r In Figs. 17 to 21, the clamp-formers are shown as comprising carriers 121 slidably engaging ways in the top 27 of the bed and fitted to the threaded portions of the screws 105. From the top of each carrier rises an angular stud or post 122 of less area than the top of the carrier whereby the top of the carrier forms a rest or support for a shaper jaw 123 which is provided with a central opening of the same configuration as the post 122 and adapted to snugly receive the post whereby twisting movement of the jaw will be prevented. Each is provided on one face with a projection 124 having a concave recess 125 whereby it may fit readily around the hose clamp, the projection being located at one side of the cen tral longitudinal line of the jaw. This con struction permits the jaw to be readily set according to the length of the hose about which the clamp is to be set. As shown in Fig. 18, the former will act on hose of one length. If the jaws be lifted from the posts, then inverted, and then reengaged over the posts, they will be set for hose of another length, as shown in Fig, 19. Each shaper jaw is provided, on the face remote from the projection 124, with a rib or tooth 126 which is narrower than said projection 124 and is disposed on the central longitudinal line of the jaw.

Many hose are torn in two, the rubber part of the hose being too short to be caught and held by the clamps 79 and 81, and in this event the teeth 126 are run up ahead of the clamps onto the hose, holding it while the fitting is pulled out.

Having thus fully described our invention, what we claim as new and desire to secure by Letters Patent of the United States is 1.
