To alt whom, t may concern:

Be it known that we, RALPH HART TwED- DELL, of Westminster, in the county of Middlesex, and JAMES BLATT and JOHN FIELD- ING, of Gloucester, in the county of Gloucester and Kingdom of Great Britain, have invented certain new and useful Improvements in Portable Riveting-Machines; and we do hereby declare the following to beafull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make andv use the same.

Our invention -relates to an improvement in portable riveting-machines, the object of the' same being to provide improved means for adjusting the riveting-machine to any desired angle or inclination; and it consists in the parts and combinations of parts, as will be more fully described, and pointed out in the claims.

In the accompanying drawings, Figure l is a view of one style ot' riveting-machine emi bodying our invention. Fig., 2 is an end View of the same. Fig. Bis a longitudinal sectional view of one of the trunnions. Fig.`4 is asimilar view of the other trunnion. Fig. 5 is a viewshowinga slightly modified construct-ion, and Fig. 6 is an end view of the same.

This improvement relates particularly to manipulating the riveter, and not to the construction of the riveter itself; and for the purpose of illustration we have shown our improvements on two distinct kinds of machines, and would have it understood that we do not limit ourselves to any particular construction, but consider ourselves at liberty to applythem to any andl all portable machines to which they are applicable.

The riveter shown in Fig. l consists of two levers connected together at a convenient point between their ends, one of said levers being provided at one end with a piston adapted to work in a cylinder formed on or attached to the adjacent end of the other lever. The lever having the cylinder thereon is provided with a valve for governing the ilowof water into and from the cylinder', which is supplied through the pipe B, one end of which is secured to the hollow trunnion A. This trun nion A supports the levers G,which latter are 5o journaled thereon, and the trunnion' is provided with a central bore, C, which latter is merely a continuation of the pipe B. This trunnion A is secured at one end to the arm D, which latter is provided at its outer end with a trunnion, E. One of the levers C is provided on the side adjacent to the arm D with a worm-wheel, Bt, which latter meshes with a worin, B5, secured to the arm D. Thus it will be seen that by turning the worm the levers 6o can be turned so as to rest in the same vertical plane-that is, the levers can be turned to a horizontal position, with their riveting-tools in a vertical position.

To one end of the bore C of thetrunnionA is secured the pipe B', through whichtheactuating-fluid is conveyed to the trunnion A. This pipe passes rearwardly alongside of the arm D, and is secured thereto at.the point B2, the said part B2 of the arm D being provided 7o withabore, a, leading to the boreb of the trunnion E. This trunnion E is journaled inthebox F, rigidlysecured to the lower open endof the arm G,and the trunnion E is provided with the worm-wheel II, rigidly secured thereto, with 7 5 which the worm I, journaled in the bearings c of the box F, meshes. Thus it will be seen that by means of the worms at the opposite ends of the arm D the machine can be turned to any angle or inclination to suit the work to be op- 8o erated on.

The arm G, before referred to, is curved, substantially as shown, and terminates over the center of gravityof the riveter. This arm is provided with an opening, c, through which the lower hooked end of the suspending link L is passed. This link is suspended from a crane or other suitable device, and forms a connection between the supply-pipe M and the flexible pipe M', which latter is preferably 9o made of copper and connected at its lower end to the trunnion E. The actuating-fluid passes from the pipe M into pipe M', and from thence, through trunnion E, pipe B', trunnion A, and pipe B, into the valve. v

In Fig. 5 we have shown a slightly-moded arrangement of parts as applied to a direct-acting ri veter. The body or frame of this riveter is made U-shaped, and provided with a cylinder, in whieha plunger carrying the movable riveting-tool works.- This cylinder communicates with the valve by the pipe B, and the valve with the trunnion A by the pipe The trunnion A in this construction need not be hollow, and is supported by the arms DL of the trunnion A., which latter is journaled in the lower end of the arm G. ln this instance the pipe B and pipe B are on the same side ot" the machine, and are secured together at the trnnnion A by a swivel joint, L.

shown in elevation in Fig. 5 is removably secured thereto by the bolts/'2 The trunnion E passes through the .lower end of the arm G, and is provided at its outer end with a wormwheel meshing with a worm. similar to that shown in Fig. 1. In this construction I have dispensed with the worm-gear on the trunnion A, and substituted therefor apinion (not shown) meshing with the rack-bar O, formed integral. with or secured to the body ot' the riveter. rlhis pinion secured to one end of the shaft O,while the worm-wheel O`, meshing with the worm 0, is secured to the opposite end of said shaft. The shaft O and worm Oi are journalcd in the removable arm 1)" ot" the trunnion E. The rack O is .toi-med in the arc ot' a circle, a-ndin the present instance will admit ot' a quarter-turn of the machine; but itis evident that the rack-bar can be continued or lengthened sufficiently to give the machine a half-turn. Thus itwill be seen that by turning the worin O the riveterwill be turned on the trunnion A, and by turning the worm l the movement ot' the riveter will be at right angles to theiirst movement. The worms and worm-wheels not onl)v a'iord means for turning the riveter, .but also eft'ectually lock the same against accidental movement.

A3y means ot' the construction shown and described the horizontal arm to which the riveter isjonrnaled can be turned so as to rotate the riveter in one direction, while by turning the riveter around its its own axis on the trunnion A. the movement is at right angles to ihe irst nnrve'inent; hence by means of the combined movements the riveter can be set at any angle or inclination to enable it to accommodate itself to the work.

Heretofore in machines ot'this vcharacter the l riveter has beenr .journaled to opposite ends oi' a curved suspending` arm7 and the curved sus pending arm inovably supported on a roller. \Vhen desired to adjust the riveter in one direction, the curved suspending` arm is moved longitudinally on the pulley. In such devices the supporting-arm is loosely mounted in the pulley, and is liable to change its position if the parts are not evenly balanced, and from the sudden jars during the operation of riveting. In our device the curved suspending arm is attached at its upper end to a hook, and provided at its opposite end with a bearing, in which a horizontal arm isjournaled, while the riveter is in turn journaled to said horizont-al arm. ly the above arrangement the riveter can be turned to any position without moving the curved arm, and as the latter is not free to move over the hook, all danger oii the riveter changing its position is obviated.

Having `fully described our invention, what we claim as new, and desire to secure by Lety ters'Patcnt, is- One of the arms Dl is formed integral. with the trunnion E, while the one on the side l. rlhe combination of a curved arm adapted to be suspended trom a crane or other suitable support, a horizontal arm journaled to the lower end ot' the curved arm, av portable riveting-machinejournaled to th c horizontal arm, and the locking devices lor locking the movable parts in any desired adjustment.

2. rlhe combinationoi' a curved suspending arm, a horizontal arm journaled thereto, a portable riveting machine iournaled to the horizontal arm, and adapted to turn on the horizontal arm in a direction at right angles to the movement ofthe said horizontal arm, and the devices for locking the movable parts 'in any desired adjustnient.

3. The combination, with a portable hydraulic riveting-mac]line and a suitable supply or pressure pipe and swivel-joints, of a horizontal arm to which the rivetilig-machine is journaled, the devices Vfor turning the machine and locking it to the arm, a curved arm to which the horizontal arm is journaled, and the devices forturning the horizontal arm and locking it to the curved arm, substantially as set forth. Y i

The combination, with a portable riveting-i'nachine provided with a rack-barformed inthe arc ol` a circle, ot' ahorizontal armjournalcd to a curved arm, and provided with apinion, the devices for turning the pinion, a woran-wheel rigidly secured to said horizontal arm, and a worm journaled tothe curved arm.

5. rlhe combination, with a portable riveting-machine and suitable supply-pipe, et' the horizonal arm, curved arln, rack-bar and pinion, worm-gear and worm, and the hook L, all ot the above parts combined as described.
