IMPROVED MACHINE FOR BENDING FIFTH-WHEELS.

- 4Specification forming part of Letters Patent No. 100,903, dated March 15, 1870.

To all whom it may concer-a:

Be it known that I, W. J'. JORDAN, of New Lisbou, Columbiana county, Ohio, have invented certain.Improvements-in Machines for Bending FifthlWheels for Vehicles; and I do hereby declare that the following is a full,

clear, and exact description of vmy invention,`

reference being had lto the accompanying drawings, forming a part of this specilication, and to the letters ot' reference marked thereon, of which drawings- Figure l is a plan of my'improved machine. Fig. 2 is a side view ofthe same. Figs. 3 are plan and side view of the bendingdie. Figs. 4 are plan and side view of the rotating arm. Figs. 5 are plan, section, and side view of 'slotted slide. Figs. 6 are side 'viewvof mechanism for operating press-wheel, and plan of.

bent-lever handle for same. Figs. 7 are plan a'nd side view of swinging block for presswheel. Fig. 8 is a side View of retaining block and rod.

The nature of my invention consists in certain improvements in machines for bending fifth-wheels for carriages and other vehicles, said improvements consisting in the novel combination of the retaining-block for holding the end of the iron t be turned into a circle with the frame and bending-die; also,

in the novel construction of mechanism for carrying the bending-Wheel; also, in the novel construction of mechanism for operating the press-wheel, these several improvements making the machine very simple and cheap in construction, and very easy to adjust to any rcquired size of work, as well as insuring its easy and correct operation.

To enable others skilled inthe art to make and use my invention, I will proceed to describe its construction and operation.

The base B 0i' the machine is secured, by 'screws or bolts Y Y, to the floor or table A, as shown. In the center and at the top of this base is iixed the center-pin G, the lower part of which is turned round to form a jour-- .nal for the rotating arm L, and the upper part of which is made of a square or angular section to prevent any rotation of the table C and bending-die D, which have holes at 'their centers to correspond with the angular section of the pin G, and set over said pin, as shown. The bending-die D is made of an ex- E and F secured ou it, as shown. ing-block H is screwed on the end of the rod ternal diameter equal to the interior dia-meter of' the wheel to-be formed, and has the lugs J ,which rod is passed through holes formed in the lugs 'E F and centerpin G, and is held by the clamp-screw K in .said center-pin, as shown in Figs. l and 2. The rotating arm L has a circular eye formed at its end, as shown in Figs.y 4, which eye iits over the circular part ofthe center-pin Gunder the table C, as shown in Fig. 2. The outer end'of the arm L is bent up, so as to bring it above the top ot' the table O, and is provided with the slots Z Z, as' shown in Figs. 2 and 4. The slide M is ot av U-shaped section, and has the slots a a formed in it, through which pass the bolts O O, which pass through the slots Z in the arm L and secure the slide to said arm. rEhe bending-wheel R is pivoted on the pin d at the end, and on the under side of the slide M, and the swinging block e is pivoted on a bolt, T, between the sides of the slide M, as shown in Fig. 2. The press-wheel Q is journaled on the pin S on the swinging block e, and the rod N is attached by a pin, X, to the block e below the bolt T, which forms the axis of motion for said block. The bent-leverhandle P is pivoted by a bolt, U, between the sides, and at the outer end of the slide M, and the rod 'N is secured to the short arm of said handle by the bolt V, as shown in Figs. 1, 2, and 6.

Now, to form any required wheel, a bending-die, D, ot' the proper size is placed on the table C, and the retaining-block H is set so as to leave a space between it and the bending-die D equal to the width of the iron to be formed, and it is fastened in this position by the clampscrew K. rlhe slide M is then fastened on the arm L by means ofthe bolts O O in such a position as to leave a space between the bending-wheel R and the bending-die D equal to the width of iron to be formed, and

the arm L is swung around, so as to bring the bending-wheel It against the block H. The wheel Q being then thrown up into the position shown in Fig. 6, the bar of iron to be formedis placed between the bending-wheel R and the bending-die D, with its end between the retaining-block H and the bendingdie, when, by pressing down the handle P,

The retainthe press-wheel Q is brought down onto the barot' iron in thc position shown in Figs. l and '2. Now, by moving the arm L around the table C in the direction of the bar to be formed, it is evident that the bending-wheel It will force the iron around onto the bendingdie D, and thus eifect the circular form required for the wheel, the press-wheel Q serving to prevent the iron from bending upward as it is bent into the circular form required.

Where the axle-clips are formed on the iron for the tfth-wheel before it is formed into the circular shape, the bent-lever handle P can be thrown up Whenever the press-Wheel Q comes to a clip in forming the wheel, which will throw the wheel Q back into the position shown in Fig. 6, and thus allow the bending mechanism to pass the clip. Byforming the lugs E and F on the bendingldieD, two points of attachment are obtained between said die and the retainingblock H, consequently no movement of' the die can take place without a corresponding movement of thel retainingblock, from which it is evident that the danger` of the bending-die and iron moving aroundV with the movement of the bending mechanism L M It Q, and 4drawv'ing-the end of the iron' from behind the block Hy so as to prevent the forming of the bar, is fully obviated.

`Having thus fully described my improved machine, what I claim therein as new Iand of my invention, and desire to secure by Letters Patent, is-

Q, rod N, and bent-lever handle P, the several part-s being arranged-substantially as and for the purposespecied.

4. The combination of the bending-die D, center-pin G, table C, rotating arm L, slide M, provided with bending-wheel It, swinging block e, provided with press-wheel Q, rod N, and bent-'lever handle P, the, several parts being arranged substantially as land for the purposefspeeied. l v

As evidence that I claim the foregoing I have hereunto set my hand in presence of two witnesses this 3d day of January, 1870.

WM. J. JORDAN.
