SPECIFICATION forming part of Letters Patent No. 404,746, dated June 4, 1889.

Application filed April 25, 1888. Serial No- 271,807. (No model.)

To all whom it may concern.-

Be it known that I, HARRISON H. TAYLOR, a citizen of the-United States, residing at Detroit, county of \Vayne, State of Michigan, have invented a certain new and useful Improvement in Machines for Assembling Radiator-Loops; and I declare the following to be a full, clear, and exact description of the i11- vention, such as will enable others skilled in IO the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to a novel machine I 5 for assembling radiator-loops; an d it consists of the devices and appliances, together with their combinations and arrangements, as more fully herewith illustrated in the drawings, and more clearly hereinafter specified, and

point-ed out in the claims.

In the drawings, Figure 1 is a plan vie Y illustrating features of my invention. Fig. is a cross-section along the line so :0, Fig. 1. Fig. 3 is a side elevation of portions of the mechanism. Fig. 4 is a longitudinal section of the chuck and related parts. Fig. 5 is a sectional view of the clutch; Fig. 6, a modification of the nipple and the manner of engaging the chuck therewith.

0 My invention contemplates novel mechanism for the assemblage of radiator loops, either for steam. or hot-water circulation, and therefore has in view to provide mechanism whereby the radiator-loops may be assembled 3 5 and connected in a desired manner at either or at both ends, as may be required. Accordingly I have shown in the drawings submitted herewith mechanism for connecting the loops at both extremities. WVhere, however, it is only desired to connect the loops at one extremity or at the base simply, a portion of the mechanism herewith shown and described may be removed or entirely dispensed with.

My invention contemplates, also, the union of the loops by means of a connecting-nipple constructed with right and left hand screwthreads to engage correspondingly screwtapped hubs on the respective loops.

The essential feature of my invention is therefore to provide suitable mechanism to form the union of the nipples with the various loops as they are added to form the completed radiator and to accomplish the work in a simple, convenient,expeditious, and efficient manner.

To this end, A represents any suitable support for the first loop or the loops already assembled. Thus it may be constructed with a vertical arm A, provided with a tapering 6o shoulder a to engage the hub of the first loop and hold it in position. \Vhere it is desired to provide for connecting the loops at both ends, the support may be constructed with an additional arm A provided with a similar shoulder a. Where provision is desired to be made to unite the loops at both ends, moreover, one of the arms A A is preferably made movable laterally, so as to serve in as semblin g loops of any desired length. Thus, for instance, the support A, of which the said arms form a part, may be constructed witlfa series of perforations a the arm A being laterally-adjustable and held in any desired location by a bolt or pin a engaged in one of 7 5 said perforations. The shoulders at a eachserve to help center the work axially, as well as to hold the loop in proper position.

B B, &c., represent a series of radiatorloops, and 1) denotes their respective hubs. 8o

. C represents a nipple for uniting adjacent loops, the nipple being constructed with right and left hand threads to engage the correspondingly screw-tapped hubs of the loops.

D is ahead-block, having, preferably, amovable engagement on the support A in any suitable 1nanneras, for instance, by a dovetailed engagement thereupon, as shown at a, Fig. 2so that it may be readily reciprocated. This reciprocation may be effected in any desired manner. Thus the head-block may be provided with a pinion d, meshing with a rackbar A upon the support A, the shaft of the pinion being provided with a hand-Wheel D.

E is a rotary chuck, which may be mounted in said head-block, and is provided at one extremity wit-h any suitable means for interiorly engaging the nipple and screw it into the adjacent loops. Thus the chuck may-be shaped simply at said end so as to enter the nipple, 10o

the nipple being constructed with hearing lugs c 0, whereby the nipplewill be rotated when the chuck is engaged therewith; or, as shown in Fig. 4, the chuck may consist of a more elaborate construction, the chuck being made with an expansible head and in a manner analogous to the construction of the chuck embodied in a patent granted to me November 24, 1885, No. 331,167, the chuck consisting of a tubular arm E',located in thehead-block, and having at one end the chuck provided with movable jaws e c, &c., having a spindle e sleeved therein, the spindle being constructed with wedge-shaped grooves c adj acent to said jaws, the spindle extending also through the tubular arm E, and provided with an operating-handle E, with which it may have a screw-tapped engagement. The movable jaws, it will be'readily observed, may thus be quickly expanded and contracted, and when entered in the nipple and expanded will carry the nipple as rotary movement is imparted thereto, thereby screwing the nipple into the adjacent loops simultaneously.

It will be noted, as shown in the drawings, that the chuck is intended to extend through the hub of the new loop to be added, and thus interiorly engage the nipple.

\Vhile the chuckis made to travel with the head-block, it will also be desirable to give it an independentreciprocatory m ovem out, since when the new loop is to be added the chuck must be removed out of the way, so that the loop can be located in position. The headblock may then be engaged against the loop laterally to press it up against the nipple, when, in addition, a further movement must also be given to extend the chuck through the hub of the loop and enter it in the nipple.

The head-block may be reeiprocated, earrying the chuck therewith, by means of the hand-wheel D, as already described. \Vhile I do not confine myself to any definite means of reciprocating either the head-block or the chuck, the reciprocation of the latter may conveniently be accomplished by constructing the tubular arm E with suitable teeth 6, with which a gear efljournaled in any desired manner upon the head-block, may mesh, the said gear being operated, for instance, by a lever E. The tubular arm E is provided at the outer end with any proper driving mechanism, as a gear E.

F is a rotary shaft mounted in extended arms D D of the head-bloek, the said shaft being provided with a driving-gear I and a pinion f, meshing with the gear E". As the said latter pinion is to mesh with the gear E, located upon the reciprocatory tubular arm E, I prefer to construct the said pinion of sutficient breadth to mesh readily with the gear, in whichever direction it may be reciprocated.

G is adriving-pulley mounted upon a shaft oi, provided with a gear G meshing with the gear F.

G is any suitable clutch having a permanent engagement upon the shaft G, while the pulley is movable to engage or disengage the clutch.

I do not limit myself to any particular clutch mechanism; but the pulley may be brought into frictional contact with the clutch by means of a conical sliding block g, provided with an operating-lever g,said block operating upon jaws g g to throw the pulley into and out of engagement with the clutch.

II is the main driving-shaft belted with the pulley G, as shown at 11. Any drivingmechanism may, however, be employed.

The mechanism to unite the opposite ends of the loops, it will be understood,will be the duplicate of that hereinbefore described, the driving-shaft being belted with a pulley G, which may be the counterpart of the pulley G, communicating its power, through intermediate mechanism similar to that already described, to a corresponding head-block and reciprocatory chuck. This duplicate mechanism may be employed or dispensed with,as may be desired.

a" denotes an auxiliary portion of the frame constituting the track of one of the duplicate head-blocks, and made movable upon the main portion of the frame A.

By making the track A of the head-blockmovable upon the support A as well as the arm A this duplicate mechanism (shown in the upper part of Fig. 1 and at the right hand of Fig. 2) may readily be removed altogether, if preferred, as well as adjusted for various lengths of loops.

It willbe immaterial, of course, which of the two duplicate mechanisms is made adj ustable the one to the other. So, also, I have shown aid described the head-block as movable; but I contemplate the adjustment of the arm A 1 or A in lieu of the reciprocation of the headblock as coming within the scope of my invention, though I prefer the reciprocation of the head-block.

In order to center and hold the hub of the new loop to be added in a proper position for union with the nipple, I prefer to cut away the tubular arm E at c", so that the chuck may enter the hub of the loop and properly hold the loop in position.

In operation a loop is first located in place upon the support, its hub being engaged at one side upon the conical-shaped shoulder a, and also upon the shoulder ct if the loop is to be connected at both ends. A nipple may then be simply entered by hand on the opposite side of the hub, the new loop to be added located in position, and the head block brought into lateral. engagement therewith. The chuck. is then moved forward and engaged with the nipple and given a rotary movement. As the nipple is being thus united with the adjacent loops, the headbloek may be moved forward to maintain its pressure against the loop.

An important feature of this device is the fact that the hubs of two adjacent loops may Where a duplicate mechanism is employedto unite the loops at both ends, since said duplicate mechanism is made movable 011 the 7 support, some suitable belt-tightener will be desiredas, for instance, the roller E.

I would have it expressly understood that I do not limit myself to any particular construction of the chuck, and that my invention contemplates any suitable device for in teriorly engaging the nipple to rotate it; and I purpose to include under the term chuck in the following claims any analogous device adapted to this end.

Any suitable means may be employed to give the chuck a reverse motion.

It is contemplated, as a simple and satisfactory method of constructing the nipples, to cut off suitable lengths therefor from ordinary gas-pipe and cut a right and a left hand screw-thread thereon.

\Vhat I claim is- 1. In combination, a loop-support A, constructed to hold the loops in position, a headblock, a shaft mounted in said head-block carrying a chuck E, projecting beyond the face of the head-block, means for reciprocating the head-block, means to reciprocate the chuckshaft independently of the head-block, and means to rotate the chuck-shaft, substantially as set forth.

2. In combination, a loop-support A, constructed to hold the loops in position, a sliding head-block D, a shaft mounted therein carrying an expansible chuck E, projecting beyond the face of the head-block, means for rotating said chuck-shaft, and means for reciprocating said chuck-shaft independently of the sliding movement of the head-block, substantially as set forth.

3. In combination, a loop-support consisting of two parallel arms constructed to hold the loops in position, and means for laterally adjusting one of said arms, a head-block having a sliding engagement on one of said arms, means for reciprocating the head-block; a shaft mounted therein carrying a chuck projecting beyond the face of the head-block, means to reciprocate the said chuck independently of the head-block, and means to rotate the chuck, substantially as set forth.

4. Incombination, a loop-support A, constructed to hold the loopsin position, a headblock D, a shaft mounted therein carrying a chuck E, projecting beyond the face of the head-block, and means to rotate the chuck, substantially as set forth.

In testimony whereof I sign this specification in the presence of two witnesses.
