ALBERT E. LYTLE, OF CHICAGO, ILLINOIS, ASSIGNOR OF TVVO-THIRDS TO JOHN H. VANHOUSEN, BEACH T. VANHOUVSEN, AND GEORGE H. EATON,
, ALL OF SAME PLAGE.
EXPANSION-ARBO R.
SPECIFICATION forming part of Letters Patent No. 301,905, dated July 15, 1884.
Application filed December 13, 1883. (No model.)
To all whom, it may concern.:
Be it known that I, ALBERT E. LYTLE, a vcitizen of the United States, residing at Chicago, in the county of Cook and State of Illi- 5 nois, have invented certain new and Vuseful Improvements in EXpansion-Arbors, of which the following is a specification, to wit:
This invention relates to an improvement' in expanding-arbors and it consists in the .ro combination, with a hollow journal, of aseries of dogs projecting through the sides of the same, and means of expanding them to clutch the saw or other article, substantially as will be hereinafter more fully set forth, and pointed I5 out in the claims.
In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, refer- 2o ring to the accompanying drawings, in which- Figure 1 is a central vertical section of the device applied to a saw. Fig. 2is a side view of the same, and Fig. 3 a transverse section of the journal 4and its clutching-dogs.
2 5 A represents ahollow j ournal or shaft, formed in its center with a series of longitudinal slots, a, and having ay hole, a, formed longitudinally through each end. Within the hollow journal-is placed a movable plug, B, closely fitting 5o the shell, and formed with a series-of inclined dovetail grooves, b, corresponding in number and location with the slots a. The plug B is provided with a screw-threaded hole, b, into which are screwed two rods, B, from opposite 3 5 ends of the shaft. Y
C C represent dogs, one of which is placed in each of the slots a, and are formed with serrations on their outer faces, as at c. The inner sides of the dogs are inclined and formed 4o with a tongue, c, which engages with the grooves b in the movable plug B. Two strengthening-disks, D D', are provided, one of .which is screwed upon the shaft, and the other may be either screwed upon or formed with the shaft, as may be desired. This device forms 45 an expansionarbor for saws, grinding-wheels,
or other tools, and when placed in position one of the rods B is loosened and the other tightened, thus drawing the plug B valong and expanding the dogs to firmly hold the 5o tool, and dispenses with the ordinary bushing used in such cases. It is applicable to a variety of uses, and may be made of any desired size.
Having thus fully described my invention, 55 what I claim as new, and desire to secure by Letters Patent,'is-
I. In an expansion-arbor, a hollow shaft or journal provided with a series of dogs projecting through slots in its sides, in combina- 6o tion with a plug placed within the journal and adapted to expand the dogs as it slides, and means for moving this plug longitudinally, as and for the purpose set forth.
2. In an expanding-arbor, a hollow shell or 6 5 journal provided with the usual clampingdisks, and formed with slotted sides, through which project movable dogs, in combination with an interior plug, formed with inclines, and suitable screw-rods entering from oppo- 7o site directions and adapted to move the plug back and forth, substantially as and for the purpose set forth.
3. In an expanding-arbor, the journal or shell A, having slots a and holes a', and the 75 clamping-disks D D', in combination with the dogs C, having serratedfaces, and a tongue,
c', formed on their backs, the plug B, having inclined grooves b, and the screw-rods B', all constructed and arranged to operate substan- 8o tially as and for the purpose set forth.
In testimony whereof I affix my signature in presence of two witnesses.
ALBERT E. LYTLE.
