SPECIFICATION forming part of Letters Patent No. 445,935, dated February 3, 1891. Application tiled October 20,1890.A Serial No. 368,701. (No model.)

To all when?, it may concern:

Be it known that I, GEORGE H. PEGRAM, of

St. Louis, in the State of Missouri, haveinven ted an Improvement in Riveting-Machines for Riveting Together the Sections Constituting a Column, of which the following is a specification.

My invention has reference to riveting-machines for riveting together the sections conro vstituting a tube or column; and it consists of certain improvements, which are fully set forth in thefollowing specifica-tion, and shown in the accompanying drawings, which form a vpart thereof.

The object of my invention is to provide suitable mechanism for handling the various sections which are employed to make up a tube or column, whereby the same may be 4riveted in a speedy manner, and preferably 2o so as to drive two rivets at the same time.

AThere tubes or columns are made of rolled sections it has been `necessary to rivet the sections together to form a complete tube or column, either by rivets driven through externally-projecting flanges,where power may be used,or internally-projected rivets, which must be driven by hand.

The object of my invention is to enable the riveting of such sections by a properly-or- 3o Aganized machine, whereby great rapidity in .themanufacture of the tubes orcolumns may be obtained.

In carrying out my invention I provide suitable means, such as a railway, for support- 55 ing the sections which have been temporarily united into the relative positions for the completed tube or column, whereby the tube or column may be moved longitudinally with `respect to a suitable riveting-machine. In 4o this particular application t-he riveting-machine is operated by hydraulic power and operates upon the inside of the tube or column, the heads of the rivets being held in position `from the outside of the tube or column by suitable mechanism,which is fully described hereinafter. The rivets are inserted from the outside through the holes in the columnsections, and are then. held in place by suitable-.adjustable anvils, which receive the 501 `strain put upon therivets when the hydraulic @r'veter upon the inside of the column is operated to put van internal head upon the said rivets.

Referring tothe drawings, Figure l is a side elevation of a riveting-machine embodying my invention. Fig. 2 is a plan view ot same with railway omitted. Fig. 3 is an enlarged plan view of the right-hand end of Fig. 2, with the post or column shown in dotted lines; and Fig. 4 is a cross-sectional view on line w of Fig.

A is a horizontal rod secured at one end to a bearing A', preferably with provision for lateral movement, and supporting at the other end a hydraulic riveter-head B. The riveterhead B is arranged between the two rivetholding anvils O C.

E is a .railway arranged below the rod A, and-upon which one or more small trucks d travel, said trucks being provided with suitable supports for the column or post D, which is formed of several sections ot any suitable cross-section. .These trucks CZ may have their supports modified or changed or made adjustable to suit the cross-section of the tube or column to be riveted. By this means the column D may be moved along parallel to the rod A, and so as to travel over the head B and maintain the series of holes in a proper line to be presented in succession to the riveting-dies b of the riveter, whereby the rivets which are passed through theholes may have their ends headed.

The riveter consists of the main head, in which a piston B operates laterally. The main head carries one ot the diesb and the piston B carries the other dies b, said dies being arranged diametrically opposite. The dies b b are readily replaceable to suit different work.l The piston B is provided with an internal cylinder D', which moves with the piston B and works upon a stationary piston cl, secured to the head It' water is forced into the port E2, the piston B is forced away from the head B and the dies b b are moved apart. It now the water is allowed to escape from the port E2 and water is forced into the port E', then the piston B', with its die, is moved into the head B. By this means a reciprocation maybe had between the two dies b. In practice this reciprocation is controlled through the valve-rod c by a valve e, (shown IOO means ofa hand-screw K.

in Fig. 1,) arranged adjacent to the support A', and connecting with the port-pipes E E2, which extend along the rod A to the head B. This valve e is of the ordinary type, which will allow water under pressure to 'flow into either port E or E2 and allow the escape of water from the other port.

Arranged upon either side of the head B, and supported upon atransverse frame J, are the two anvil mechanisms C for holding the rivets in place in the tube or column during the riveting operation. These devices are the same upon each side of the rivet-head, and

therefore I will describe but one of them.

F is the anvil-die, and is fitted to a reciprocating head G, guided in the main frame J. This head G may be reciprocated bymeans of a toggle L, which is operated by a link Z and a treadle motion M of any suitable description. Vhen the toggle L is raised into a locking position, the anvil-die F will be pressing against the head of the rivet. For various sizes of columns the anvil-die F may be changed as to its length, and thereby compensate for the difference in space required.

Il is a block having a vertical face adjacent to the head G and an oblique face to the rear, working in a suitable guideway on the main frame J. This block is moved vertically by The vertical edge of the block H is provided with vertical guidegrooves g, in which is guided a verticallymovable locking-block I, having a pin e' to strike upon the trame .l and sustain the said block after having fallen to a distance sufficient to actas a thrust or locking block for the head G. When the parts are in the position shown in Fig. 4, a vmovement of the treadle M will cause the head G to be projeeted forward toward the column, and upon this operation taking place the locking-block I, which is sustained by the head G before the operation, is allowed to fall by gravity and comes between the rear end of the head G and the block H and receives the thrust put upon the anvil-die F. Slight adjustments can be made by means of the wedge-shaped plug H being moved up or down by means of the screw K. Before the anvil-die can be withdrawn the block I must be raised, and then upon withdrawing the anvil-die and its head G the block I will be sustained, as indicated in Fig. l.

The operation of projecting the anvil-dies F toward the column on each side takes place simultaneously and is under the control of the same foot-treadle M. As soon as the rivets have been inserted the anvildies are thrust forward and locked in position. The hydraulic riveter is then operated and the rivets have their inner ends upset or headed, completing the riveting operation. As soon as this is done the dies b are drawn together and the dies F are moved apart. The column is then moved over the railway to the next rivet-hole and the operation repeated once more.

It is evident that one ot the anvil devices C and the riveter might be employed for single riveting; but in this case the head B would have to be rigidly sustained against the thrust due to the riveting operation, but otherwise my mechanism is equally adapted to single riveting for flanges or flat work.

It is immaterial to my invention whether the apparatus is arranged horizontallyor vertically, as it may be arranged at any angle, so that the work may be fed horizontally, vertically, or obliquely, the guides for the work being modified accordingly, as would be seltevident to any mechanic.

Ido not limitniyselt' tothe details of construction herein set ont, as they may be modiied in various ways without departing from the principles of my invention.
