APPARATUS FOR SUSPENDlNG PORTABLE RlVETlNG-MACHINES.

SPECIPICATIQN forming part of Letters Patent No. 307,282, dated October 28, 1884:.

Application filed A pril I9, 1884. (No model.) Patented in England March 25, 1852, No. 1,4351; in France September 8, 1882,

No. 151,016, and in Belgium September 1852, No. 518,971.

To all whom it may concern:

Be it known that I, JOHN FIELDING, of

Gloucester, in the county of Gloucester and Kingdom of Great Britain, have invented certain new and useful Improvements in Apparatus for Suspending Portable Riveting-lllachines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable othersv skilled in the art to which it appertains to make and use the same.

My invention relates to an apparatus for suspending portable machines employed for riveting and such like operations, the object being to obtainin a simple manner facilities for applying the tools of such machines at various points and in various directions, according to the work that they have to perform. To accomplish this end, I fit on a trunnion on either side of the machine, at or near its center of gravity, asleevc, within which the trunnion can revolve, and to the sleeve I joint, by two parallel links like those of a parallel ruler, a bar projecting beyond the links a distance such that its end is nearly above the center of the machine. The machine, being suspended by a swivel attached to the end of the bar, can be turned into various attitudes, so that its tools can be presented at any required point and in any required direct-ion within the limits permitted by the jointing. In cases where the machine is worked by hydraulic or other fluid pressure, the fluid can be supplied through the trunnion, being conducted thither along the bar and either of the links, which may for that purpose be made tubular, or by a separate pipe with suitable swivel-joints.

In the accompanying drawings, Figure l is a view in side elevation of one form of machine embodying my invention. Fig. 2 is an edge view of another form of machine, and Fig. 2 is aviewin side elevation of the machine shown in Fig. 2. Fig. 3is an end view of the links shown in Fig. and Fig. 4 is an enlarged view, in section, of the trunnion.

A represents a portable riveting-machine provided with a trunnion, A, formed on the back thereof nearly in the line of the center of gravity of the machine. This trunnion is embraced by a sleeve, 13, within which the trunnion is free to turn. This sleeve B is connected by two links, 0 G, like those of a parallel ruler, to a beam, D, having at its end the suspensiondink E, nearly in the line of the centor of gravity of therlvefer. F is the valve-box, provided with the sup plypipe H and with the discharge G, through which the exhaustwater passes. The lower end of the link 0 is provided with teeth arranged in the are of a circle, which latter mesh with the worm I, journaled to the sleeve B. Thus it will be seen that by turning the worm in one direction the rivetcr, by reason of its weight, is permitted to turn, which elevates the link 0, while the joint a is lowered, caus ing the two links and the beam D to assumea vertical position, with the free end of the beam 1) downward, as shown in dotted lines of Fig. 1. By reversing the motion of the worm the riveter can be turned in the opposite direction.

In Figs. 2 and 2 a slightly modified construction of parts is employed in connection with a different style of portable rivetingniacliine. This riveting-machine consists, essentially, of two levers pivoted together, one of said levers being provided at one end with a cylinder, M, and at its oppos te end with a riveting-tool, while the other lever is provided at one end with a plunger moving within the cylinder, and at its opposite end with a riveting-to0l adapted to operate in conjunction with the riveting-tool of the other lever. The links are connected to the sleeve 13 as before described, and the upper ends thereof are pivotally secured to the hydraulic liftcylinder K, to be referred to further on. The actuating-fluid is supplied to the valve-box F by the pipe H, which latter is connected by means of packing-rings and nuts to the hollow arm M formed on or with the sleeve 13. This hollow arm is in communication with the passageway M of the trunnion A by the port M. To the opl posite end of the trunnion A is connected the pipe H, which conveys the water to the box F. In Fig. 2 I have dispensed with the beam D of Fig. 1, and employed instead thereof the hydraulic lift-cylinder K, which latter is provided with a plunger having a pulley, c, j ournaled to the outer end thereof. A chain, L, secured at one end to the cylinder of the lift, passes under pulley c and under pulley c at the opposite end of the lift, and from thence to a crane or other overhead support. In this instance the supply-pipe H passes downwardly alongside of the link 0 and communicates with the hollow trunnion through the ports M and M.

I11 the construction of parts shown in Fig. 2 the trunnion A is made fast to the sleeve B, and the riveter revolves on the said trunnion, but is held against accidental turning by a set screw.

From the foregoing it will be seen that by turning the screw Ithe inclination or angle of the riveting-machine can be varied at pleasure, and by simply admitting water to the cylinder K behind the plunger the machine can be elevated.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination, with a portable riveting-machine provided with a trunnion, of a sleeve embracing one end ofsaid trunnion, and parallel links pivotally connected at their lower ends to said sleeve, and pivotally connccted at their upper ends to a movable sup- 0 porting device.

2. The combination, with a portable riveting-machine provided with a trunnion, of parallel links pivotally secured at their lower ends to the sleeve, and pivotally secured at their upper ends to a hydraulic lift, substan 5 tially as set forth.

The combination, with a portable riveting-inachine provided with a trunnion, of a sleeve embracing the trunnion, parallel links pivoted at their lower ends to the sleeve, and connected at their upper ends to a hydraulic lift, and the Worm and segmental gear, substantially as set forth.

4. In a hydraulic riveter, the combination of a portable riveting-machine provided with a hollow trunnion, the sleeve embracing said trunnion, the links pivotally secured at their lower ends to the sleeve and at their upper ends to a movable support, and pipes connecting with the trunnion through which the actuating-fluid passes, substantially as set forth.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

JOHN FIELDING.
