CHARLES WV. BARNABY, OF SALEM, OHIO, ASSIGNOR OF ONE-HALF TO THE BUCKEYE ENGINE COMPANY, OF SAME PLACE.
ECCENTRIC.
SPECIFICATION forming part of Letters Patent No. 287,406, dated October 30, 188?.
Application filed August 23, 181 3. (No model.) I
To aZZ whom it may concern Be it known that I, CHARLES W. BARNABY, of Salem, in the county of Oolumbiana and State of Ohio, have invented certain new and 5 useful Improvements in Eccentrics, of which improvements the following is a specification.
My invention relates to split eccentrics that is to say, those which are divided into two separate sections radially to the axis of their IO shaft-opening, in order to enable them to be conveniently placed on an d removed from thesh afts upon which they are designed to operate.and is likewise applicable to collars, sleeves, pulleys, or other members which ,it may be desirable to place upon shafts in two halves.
The objects of my invention are to simplify and cheapen the construction of eccentrics of the class referred to, and to insure the accurate fitting of the sections when united, without the 2 necessity of subsequent manipulation.
To these ends my improvements consist in a section having a tongue or lug projecting from its butting-face on each side of the shaft-opening; also, in a section having a recess located on each side of its shaft-opening and extendi ng without obstruction from said opening to its periphery; also, in the combination of a section having a projecting tongue .on its butting-face, on each side of its shaft opening, a
section having recesses in its buttingface adapted to receive said tongues, and bolts by which said sections are coupled one to the other. 1
The improvements claimed are hereinafter 3 5 fully set forth.
In the accompanying drawings, Figures 1 and 2 are side and face views, respectively, in elevation, of an eccentric embodying my in vention; Fig; 3, a vertical transverse section through the larger part or section of the same;- Fig. 4, a side view, in elevation, of the smaller section; Figs. 5 and 6, transverse sections at the line a: w of Figs. 3 and 4, through the larger and the smaller sections, respectively, of the eccentric; and Fig. 7, a View, in elevation, of
one of the connecting wedge-bolts.
In the construction of split eccentrics, as practiced prior to my invention, the buttingfaces of the two sections have been planed flat,
and the two sections connected by means of studs with the cored holes.
' studs screwed into the smaller section and having squared projections entering similarlyformed holes cored in the larger section, mortises being formed in the projections of the studs and in the body of the larger section of 5 5 the eccentric, through which connectingbolts were passed for the purpose of securing the two sections together. Such construction is objectionable in involving the necessity of laying out, drilling, and tapping the holes for the studs, making and attaching the studs so that. their rough, forged, or even finished surfaces would approximate the position and direction of the sides of the holes against which they were drawn by the action of the bolts in draw- 6 ing the 'sections'together, and in the difficulty experienced in obtaining a proper and accurate joint between the sections by reason of the imperfect contact of the projections of the The expense, de- 0- lay, and unsatisfactory result above referred to I havefound in practice to be wholly obviated by the employment of myimprovements.
To carry out my invention I cast upon the smaller section, A, of the eccentric,two tongues 7 or lugs, a, each of which projects perpendicularly from the butting-face a of the section, and to afford all practicable strength should extend from its periphery to its shaft recess or opening (1 ting-face b of the larger section, B, of the eccentric on each ,side of its shaft-opening b", said recesses being in line, one with the other, transversely to the shaft-opening and in line 2 and corresponding in width with the opposite tongues, a, of the smaller section, A. Each of the recesses b extends unobstructedly from the shaft-opening b to the periphery of the section, and is thus adapted to be planed out for its entire extent, so as to accurately fit the sides of the tongue a, which enters it, the tongues as well as the butting-faces of both the sections being likewise planed, so that neat and accurate fitting of all the surfaces in contact may be attained. The two sections, after he 5 ing properly finished as above, are secured firmly together around the shaft, preferably by wedge-bolts O, which pass through mortices a in the tongues and b in the metal of the larger section, B, on each side of the re- A recess, 1), is formed in the but- 80 cesses b, and are secured by nuts 0. To afford sufficient space to admit the portions of the tongues exterior to the mortises a without involving unnecessary machine work or weakening of the section B, pockets b of greater width than the tongues may be cored in the bottoms of the recesses b, contact of the tongues therewith not being necessary beyond the wedge-bolts O.
In eccentrics constructed in acccordancewith my invention there is no tendency for the butting-faces to be drawn out of line in connectingthe sections, nor any possibility of such derangement by reason of the perfect contact of the sections, which is wholly on finished surfaces. The sections will necessarily match in every direction when drawn together on' the shaft, the shaft bringing them to the correct position in one direction and the tongues and recesses in the other. The eccentric may, if desired, be secured upon the shaft at the same time that its sections are connected together by making the fit such that the shaft will be tightly clamped as the sections are brought to their meeting position. For greater security against slipping, keys, wedge-bolts, or setscrews may be employed in the usual manner, and it is preferable that the connecting-bolts should be used merely to draw and hold the two sections firmly together, so as to form practically a solid eccentric, which may be moved and adjusted upon the shaft without disturbing the connection of its sections, and is held in desired position upon the shaft by the devices ordinarily employed for the purpose. will further be obvious that my improvements I are applicable, vwithout variation of principle,
collars, or any other attachto pulleys, hubs,
to be placed upon a shaft in ments which are two sections.
I claim as my invention and desire to secure by Letters Patent-- 1. An eccentric-section having a tongue or 7 lug projecting from its butting-face on each side of a semi-cylindrical shaft-opening, and within the end boundaries of the butting-face,
1 said tongue and butting-face being adapted to be acted on by a planing or finishing tool, substantially as set forth.
2. An eccentric-section having a recess located in its butting-face on each side of and transverse to its shaft-opening, and extending without obstruction from said opening to its periphery, so as to be adapted to be acted on by a planing or finishing tool, substantially as set forth.
3. An eccentricsection having an unobstructed recess on each side of and transverse to its shaft-opening, and a cored pocket of greater width than said recess at'the bottom thereof, substantially as set forth.
4. The combination of an eccentric-section having a projecting tongue on its butting-face on each side of a semi-cylindrical shaft-opening, a section having recesses in its buttingface adapted to receive said tongues and bolts passing through mortises in the tongues and in the metal on each side of the recesses, and
serving to connect the sections one to the other, substantially as set forth.
