Description
UNTTED sTATEs PATENT oEEToE.
M. S. CURTISS AND EDGAR ST. JOHN, OF BINGHAMTON, NE\V YORK.
Specification of Letters Patent No. 9,180, dated August 10, 1852.
To all whom it 'may concern.:
Be it known that we, MARSHAL S. CURTISS and EDGAR ST. JOHN, both of Binghamton, in the county of Broome and State of New York, have invented certain new and useful Improvements in the Construction of Railroad-Frogs; andv we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing, and letters marked thereon, forming a part of this specification.
Our invention consists in the ypeculiar manner of constructing the shank of the movable point, with projections or hooks fitting a corresponding slot. or channel formed with recesses in the bed-plate thereof, whereby said point is secured in its seat by a wedge shaped spike pressing against the end of the frog pointand passing through said bed-'plate into the frog block below, which forces said point close against the truncated end of the frog, and it may be further secured from any vertical or lateral movement by the insertion of bolts, horizontally, through its shank andsaid bed-plate, thus obviating the practical disadvantages arising from the present method, in general use, of drilling holes, vertically, through that part Soof said point most subject to the tread and in the shape and use ou railways. The movable point A, is-
friction of the flangesof the wheels, and lessening the expense of constructing, keepi'ng the whole frog in eicient repair, and, consequently, augmenting its durability.
The accompanying drawing (Figure 1) represents a top View of the bed-plate and a separate view of the frog point removed from its seat, and Fig. 2 a section of thev whole, with the movable'point secured to its seat.
Ve construct the frog of castiron, all, except the movable point, cast in one operation, dimensions now in general made of wrought iron, provided with a shank of about 1% inches Wide, which shank is of a peculiar form to suit its Seat. The bodyof said shank C, projects about 2, and theends thereof about 4, inches, terminating in the form of hooks D D.
Formed in the bed-plate E, is a slot or channelF, extending from about 4 inches from the truncated end to 14 inches. This channel corresponds to the width of the shank C, and is the length of one of the hooks Dv D, and at each end it is deepened to receive the projections on'which the hopks are formed, and recesses-are cut under said channel, and in toward the truncated end corresponding with, and for receiving, the hooks D D.
The frog and movable point thus constructed, the point is secured to its seat by placing it into the channel and sliding it up toward the truncated end, which forces the hooks D D to enter the recesses under the channel, and then inserting a spike H, which draws said movable point close. against said truncated end. It may be further secured,
from any lateral or vertical working, bv insertingl horizontal bolts through the vbedplate and shank, if desired. y
Y'Vhat we claim as new in our invention, and desire to secure 4by Letters Patent,- is,
The combination ofthe peculiarly formed shank of the frog point and its corresponding,"channel and socket, said point secured toits seat by spike and bolts, or their equivalents, substantially as described.
In testimony whereof We have hereunto signed our names before two subscribing witnesses.
M. S.- CURTISS. E. ST. JOHN.
