FELLY-PLATE.

SPECIFICATION forming part of Letters Patent No. 257,279, dated May 2, 1882.

Application filed March 14, 1882. (Model.)

To all whom it may concern:

Be it known that I, JOHN B. BLATT, a citizen of the United States of America, residing at Reading, in the county of Berks and -State of Pennsylvania, have invented certain new and useful Improvements in Felly-Plates; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention has relation to certain improvements in felly-plates for vehicle-wheels.

Heretofore afelly-plate has been made from a sheet of metal of suitable thickness, and

curved so as to tahe inner surface of the felly to which the plate is to be applied, and is secured thereto .by means of two bolts and nuts. This construction of, a felly-plate is objectionable for the reason that owing to the close proximity of the bolt-holes in the plate the bolt-holes through the fellies for the passage of the bolts to make the connection are necessarily brought so near to the ends of the fellies as'to frequently cause them to split, thereby weakening the wheel.

The object of my improvement is to overcome this difculty; and the novelty consists in constructingy a spring felly-plate of such a length as to bring the bolt-holes in the ends thereof near where the spokes pass into the felly, and so as to bear with its greatest pressure directlyon the felly-joint, thereby affording great power of resistance at thejoint against severe concussions and strains, as will be hereinafter more fully set forth.

In the annexed drawings, forming a part of this specification, Figure l is a side view ot'.

a portion of a vehicle-wheel, showing my improvement applied thereto. Fig. 2 is a perspective view of a portion of a vehicle-wheel, showing the spring felly-plate covering the felly-joint; and Fig. 3 is a perspective view of the spring folly-plate.

In Fig. l the letterArepresents the felly of a vehicle-wheel, showing the meeting ends thereof, and the letter B represents myimproved spring felly-plate arranged over the joint or meeting ends ofthe felly, and attached to the tire and felly by means ofthe bolts and nuts. This spring felly-plate, which may be struck up by means of suitable dies, or otherwise formed, is made of such length as to eX- tend nearly the entire distance of the space between two spokes where they enter the felly. This spring felly-plate is curved in the direction of its length to conform nearly to the circle of the felly, and transversely is concave to correspond to the convexity of the felly to which it is applied. The side edges of this plate in the central downward extensions are gradually reduced in thickness from the center to a feather-edge, so as to be Hush or even with the sides of the felly, and the arms ofthe plate gradually converge in coniiguration to the end, with the lateral central portion of the plate setting on the felly, the thickest and strongest, with the seat of the spring resting on the joint, and from the center the metal converges toward each end. Near each end of the plate are formed bolt or rivet holes for the reception of bolts or rivets to connect the plates with the felly and tire.

This spring felly-plate is so constructed and shaped that in applying it to the inner circle of the felly it will require a pressure of from one hundred and twenty-five pounds to one hundred and forty pounds to draw the spring down iirmlyat its ends and set the plate firmly to the felly and tire.

By reference to the drawings it will be observed that the end fastening means are located near where the spokes enter the felly,

so as to retain the full strength ofthe felly at Y the point of meeting, and thus protect the joint of the fellies from breaking or splitting in attaching the plate, or by concussions and strains, and also serving to preserve a uniform circle in the wheel.

What I claim as my invention, and. desire t secure by Letters Patent, is

l. As an improved article of manufacture, the spring felly-plate herein described and shown, curved in the direction of its length, and eoncaved transversely to correspond to the circle and convexity of the felly and converging ends, with bolt or rivet holes, for the purpose set forth.

2. The combination and arrangement, in a vehicle-wheel, of the spring telly-plate curved to suit the circle and convexity of the felly, and connected at the ends to the felly and tire by means of bolts and nuts or rivets located nea-r the spokes, as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.
