Description
5. w. LUITWIELER CAM AND SPINDLE CONSTRUCTION Filed July 9, 1923 ATTORNEY J BAA/111% WMWFEFER- I I BY Patented Oct. 21, 1924.
UNITED STATES PATENT OFFICE.
SAMUEL W. LUITWIELER, OF ROCHESTER, NEW YORK.
CAM AND SIPINDLE CONSTRUCTION.
Application filed July 9,
Torall whom it may concern Be it known that T, SAMUEL VJ. LorrwinLnR, a citizen of the United States of America, residing at Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Cam and Spindle Constructions, of which the following is a specification.
My invention relates to a cam and spindle assembl and has to do more particularly with mounting one or more cams on a spindle so as to afford a strong, rigid, and firmly tied unitary structure.
A further object of the invention is to provide an arrangement that can be readily and, economically manufactured, and which lends itself to a practical assembly, especia-lly adapted for use in pump and engine construction.
Other objects and advantages of the in vention will appear more clearly from the following description, when read in conjunction with the accompanying drawing, the novel features being pointed out in the claims following the specification.
In the drawing:
Figure 1 is an end elevation, with the supporting spindle in section, of mechanism constructed in accordance with a preferred embodiment of the invention;
Figure 2 is a longitudinal vertical sectional View on line 2 2 of Figure 1;
Figure 3 is a transverse vertical sectional view on line 33 of Figure 2, and
Figure 4 is an end view of a modification.
The invention includes a divided spindle embracing opposite spindle portions 1 and 2 which include end plates 3 and f, preferably formed integral with the spindle portions 1 and 2. The end plates 3 and 4, are also provided with annular locking portions 5 and 6 consisting of alternately arranged recesses and projections, and in the arrangement illustrated in Figures 1 to 3, each annular locking portion on the end plates includes three recesses and three projections for locking cooperation with the cams, as will appear momentarily.
Arranged between the end plates 3 and 4: are cams 7, three such cams being disclosed in the illustrated embodiment, arranged symmetrically about the spindle for cooperation with rollers 8, as/usual in cam- 1923. serial No. 650,398.
driven machinery. Each cam 7 is provided on its opposite sides with annular locking portions or collars 9, said locking portions embod ing alternately arranged recesses and pr jections as on the end plates 3 and 4 previously mentioned. The locking recesses and projections are so disposed on the respective end plates and cams as to permit of interlocking engagement between adjacent faces of the cams, and between the end plates and adjacent cams, while retaining the symmetrical relationship of the cams to the spindle on which they are mounted. The arrangement of Figure 4c differs from the previously described arrangement, inthat it includes only two interlocking recesses and projections on each annular locking portion, instead of three. 7
- The cams are held thus assembled by suitable connecting means, preferably consisting of rods 10 passing through openings in the end plates and in the annular locking portions of the cams and held in place by nuts 11. 12 is a guide or centering rod supported in openings in the spindle portions 1 and 2 centrally thereof and passing through corresponding openings in the respective cams, thus serving to insure proper centering of the cams with respect to the spindle and contributing to a more rigid and unitary construction. The parts can be readily taken apart or assembled, and while the mechanism which I have disclosed can be employed in the attachment of a single cam, it is particularly adapted to assembling a series of cams on a spindle, where rigidity and strength are important factors to be consid ered.
While I have described the invention with reference to a particular construction, it is not limited to the details disclosed but may be modified or otherwise adapted without departing from the fundamental features of the improvement, as comprehended by the following claims.
I claim:
1. The combination with a divided spindle including oppositely disposed end plates, of a cam located between said end plates and having interlocking connection therewith, and attaching means for the cam and end plates.
2. The combination with a divided spindle including oppositely disposed end plates, of a cam located between the end plates and for interlocking With one of the end plates, and attaching means for the cam and end plates.
a opposite sides including alternately arranged recesses and projections for interlocking cooperation With adjacent locking portions, the end plates having corresponding locking portions for engagement With the adjacent cams, and attaching means for the cams and end plates.
5. The combination With a divided spindle including end plates, of a plurality of cams located between the end plates and provided With annular locking portions on opposite sides including alternately arranged recesses and projections for interlocking cooperation With adjacent locking portions, the end plates having corresponding locking portions for engagement With the adjacent cams, a guide rod alined centrally of and supported in the opposite portions of the spindle, said rod passing through openings in the cams, and attachmg rods extending through openings in the annular locking portions of the cams and the adjacent end plate or cam, a centering rod arranged centrally of and supported in the opposite portions of the spindle and passing through openings in the cams, and 0 a series of attaching rods extending through openings in the annular locking portions of the cains'and end plates for securing said parts together.
7 The combination With a divided spindle, of a series of cams having interlocking connection With each other, the end cams having interlocking connection-With the adjacent parts of the spindle, and means for securing the cams and spindle together.
In Witness whereof, I have hereunto signed my name. I
SAMUEL W. LUITVVIELER.
