Description
MADDEN & BUSHNELL Thill Coupling. No. 96,935. Patentd Nov. 16, 1869.
@Htmtt Gtjiflinc.
JOHN MADDEN AND UPSON BUSHNELL, OF CLEVELAND, OHIO.
Letters Patent No. 96,935, dated November 16, 1869.
IMPROVED THILL-SHACKLE.
The Schedule referred to in these Letters Patent and making part of the same.
To all whom it may concern:
Be itknown that we, J OHN MADDEN and UPsoN BUSHNELL, of Cleveland, in the county of Ouyahoga, and State of Ohio, have invented certain new and useful Improvements in Thill-Shackle; and we do hereby declare that the following is a full and complete description of the same, reference being bad to the accompanying drawings, making a part of this specification, in which- Figure 1 is a side view of the shackle.
Figure 2, a view of the top.
Figures 3 and 4, detached sections.
Like letters of reference refer to like several views presented.
This invention-relates to a shackle or clip, whereby the chills are attached to a carriage in a strong, certain, and flexible manner, and providing the joint of the shackle with a chamber for the reception of oil for lubricating the same. 7
In fig. 1, A represents the clip-section of the shackle,
parts in the said section being the part attached to the axle-tree,
and B, the section attached to the thills. v
The joint, whereby the two sections are connected, consists of two concentric circles or corrugations, OD, fig. 4, having an angular character in their transverse direct-ion.
. These annular corrugations are made to-fit in corresponding grooves, E F, fig. 3, sunk in the rounded part of section B, when the two sections are placed together, as shown in figs. 1 and 2, whereby they move upon and within each other on moving the thills in a vertical direction.
It will be observed that section B, in its connection with its corresponding part, laps over upon it, thereby covering the line of contact of the two sections, thus excluding sand and dirt from finding their way in between them, thereby avoiding the friction and consequent wearing of the two sections by the absence of dirt.
' It will also be observed that the bottom of the groove E is square; the square being sunk below the angle of the groove, forming an annular chamber, a, of a square character, below the groove.
In said chamber may be placed a piece of cotton, saturated with oil, or it may be left free, and filled with oil for lubricating the joint. By this means it is self-oiling, and will therefore require but little looking after for the purpose of oiling. I
The two sections are secured to each other by the screw-bolt G passing freely through section B, and screwed into section A. For further security, the end of the bolt is furnished with a nut, H, which effectually prevents it from working off.
It will be obvious, that by this construction of the joint, there islittle or no strain exerted upon the bolt, but that the strain is wholly upon the annular circles; therefore great strength is obtained to the coupling, which, in consequence of the large fitting surface, will permit no rapid wearing of the two parts upon each other.
This manner of shackle is neat in appearance, strong and durable. Hence, for the purpose for which it is especially intended, it is well adapted.
What. we claim as our invention, and desire to secure by Letters Patent, is-
The thill-shackle, composed. of the parts A and B, bolt G, and nut H, the parts A and B constructed and arranged in the manner and for the purpose substantially as described JOHN MADDEN. UPSON BUSHNELL. Witnesses:
J. H. BURRIDGE, FRANK S. ALDEN.
