ROLLO G. MANNING, on Ansinnen, ,PENNSYLVANIA RAIL CLAMP.
Application filed May 17,
To aZZ whom t may concern:
Be it known that I, ROLLO G. MANNING,
a citizen of the United States, and resident of Ambridge, in the county of Beaver and State of Pennsylvania, have invented certain new and useful Improvements in Rail Clamps, of which the following is a specii` cation.
This invention relates to rail clamps and more particularly to adjustable rail clamps adapted to line up, clamp, andfirmly hold a rail to its support, and has for one yof its objects the provision of suchl a clamp particu# larly adapted for use in clamping rails supporting turntables,
Another object is to provide a clamp of this class that may be securelvv locked in its adjusted position. f
A further Object is t0 provide a clamp of this class that will permit very slight .adjustments of the rail at right angles to the normal upright position of the rail. f f
A still further object is to provide arail clamp having the novel construction, design, and combination of parts hereinafter described.
In the drawings- Figure 1 is a plan of a rail secured in poi sition by clamps constructed in accordance with my invention.
Figure 2 is a .sectional elevation through the rail of Figure 1, showing one of the clamps in elevation and the other lin section."
Figure 3 is a plan of the eccentric adjusting disk or washer.
Figure 4 is a plan of a slightly modied form of clamp. ,l
Figure 5 is a sectional elevation through a rail having the clamps of Figure 3 ap-l plied thereto, the one clamp being in section and the other being in elevation.
Referring more particularly to Figures 1 and 2 of the drawings, the numeral 2 designates a rail adapted to be secured on a supporting plate 3 by the clamps A.
The clamps A comprise a clamping plate 5 which is cut away along its one edge to form an extended flange 6 and shoulder 7, adapted to overlie the top face of, and contact with the edge of the base flange orp the rail, respectively. The plate 5 is provided with a centrally arranged circular opening traveling cranes, and

8 which is enlarged at its upper end as at 9 Jo-iforin. a seat for Ya washer 10.
TheV washer l0 is provided with an eccentrically positioned aperture 10@L adapted to receive a bolt 11 which .p-assesthrough the. opening 8 and, is secured in the supporting plate 3. The washer 10 also is provided With an aperture 12 for the reception of a suitable wrench or toolused in rotating the washer. relative to the clamping plate 5, and .to permit the operator to insert his finger or a toolk in lifting the Washer from its seat.
It will'be readily understood that any rotation orn the washer 10 relative to the clamping plate 5 will, due to the eccentric mounting or the washer, cause the` plate 5 to move toward or away-from the rail.
The lside wall of the enlarged portion of the openingl 8, forming seat V9, has its side walls provided with aplurality or series of semi-circular recessesor notches la which extend around its entire circumference, and the washer 10 yis provided with three similarA recesses or notches 15 whichl are adapted to cooperate with the notches letto form circular openings for the reception of a locking pin 16. The pin 16 `is adapted to be inserted in the opening formed by the registering notches 14 and 15 after the washer l0 has been rotated to adjust the. rail and forms a positive lock to prevent further movement of the washer relative to `the clamping plate. v
A. suitable covering disk or washer 18 is mounted over the bolt 1l and extends partly over both the clamping plate 5 and `the washer 10 and is adapted to cover the opening .formed by the cooperating notches let and 15. v l
The `bolt 11 is provided with nuts 19 `and 20 which are adapted to be tightened down against the washer 18 to secure the several parts together. It, for any reason, the nuts 19 and 2O should become loosened, the rail 2 will not be effected since the locking pin 16 will hold the several parts intheir adjusted position. o f
1n Figures 4 and 5 I have shown a slightly modiiied form of clamp in which the notches'- let are omitted from the walls of the seat port-ion 9 and a tongue or lug 25 substituted, and in which the three notches 1 5 in the Washer l0 are i'eplaced With a continuous series of notches 26 extending entirely around its circumference.
in this construction when it is desired to adjust the rail it will be necessary to loosen the nuts i9 and 20 sufhciently to permit the washer l() to be lifted out ot' the seat 9 and to then rotate it about the bolt l1 until the desired. adjustment is made, when the Washer will be again seated with one of the notches 2G registering with the lug 25. It will also be noted that the covering plate or Washer 18 is omitted from the modiii'ed construction of Figures 4; and 5 since there is no loose locking pin as inv the preferred construction and, therefore, the washer 18 is unnecessary.
`While l have shown and described two embodiment-s of my invention, it Will Vbe understood that my invention is not limited to these constructions, since various modilications which Will readily suggest themselves to those skilled in the art, may be made ivithoutdeparting from the scope o my invention as defined in the appended claims.
I claiml. The combination With a rail supporting member, of means Jfor -adjustably securing a rail to said member, said means comprising a clamping plate having a circular opening therein, an eccentric Washer member mounted in said opening, said clamping plate having its Walls surrounding said opening provided with a series of semicircular notches extending around its entire circumference, and said Washer being provided with a plurality of corresponding semi-circular notches adapted to cooperate i iviththe notches in said plate to form circular openings for the reception of a suitable loclring pin, a covering disk mounted over said eccentric Washer and extending over a portion of said clamping plate, and a bolt passing through said disk, said Washer, and said rail supporting member, said bolt being adapted to secure all of said parts together.
2. The combination with a rail supporting member, of means tor -adjustably securing a rail tov said member, said means comprising a clamping plate having a circular opening therein, an eccentiic Washer member mounted in said opening, said Washer being provided ivith a series of notches.l means cooperating with said notches to lock said Washer against movement relative to said clamping plate, and a bolt passing through said Washer and said plate to secure said parts together and form a pivotal mounting for said Washer.
3. The combination with a rail supporting member, of means for adjustably securing a rail to said member, said means comprising a clamping plate having a circular opening therein, an eccentric Washer member mounted in said opening, said Washer being provided With a series of notches, means cooperating with said notches to lock said Washer against movement rel-` ative to said clamping plate, said Washer being provided with 'a tool receiving aperture adapted to receive a tool to facilitate the adjustment of said Washer, and a bolt passing through said Washer and said plate t0 secure said parts together and form a pivotal mounting for said Washer.
et.
