JOSEPH DANIEL OVIDE DUBRULE, OF MONTREAL, CANADA.
EXPANDING MANDREL.
SPECIFICATION forming part of Letters Patent No. 447,667, dated March 3, 1891. Application filed September 2, 1890. Serial No. 363,778. (No model.) Patented in Canada October 6, 1890, No. 35,184
T0 to whom it may concern.-
Be it known that I, JOSEPH DANIEL OvIDE DUBRULE, of the city of Montreal, in the district of Montreal and Province of Quebec,
Canada, have invented a new and useful Improvement in Expanding Mandrels, (for which I have obtained Letters Patent in Canada No. 35,148, granted October 6, 1890;) and I do hereby declare that the following is a full, clear, and exact description of the same.
My invention relates to expanding mandrels generally, and has for its object to render the same extensible as to length, capable of use in conical as well as cylindrical holes, and, further, to secure an easy adjustment of the parts. The extensibility in length is secured by the combination, with a stationary expansionhead on the spindle, of a movable expansionhead working on a screwed portion of such spindle. The expansion-heads are composed of cones and wedges, the latter having the smallest connection possible with the cones and being adjustable longitudinally along the outer surfaces of the same; and if a conical hole is to be fitted, these wedges, which make up the difference between the conical shape of the cone and the cylindrical, are adapted to be so disposed as topresent a small diame ter at one end and alarge diameter at another. As the expanding-wedges are adj ustable longitudinally along the cones,I am able to use nuts on screwed portions of the spindle, which nuts, throughaloose washer, bear upon the ends of the wedges and serve to adjust them along the cones, thus avoiding any necessity for hammering the spindle, which in variably spoils the centers. For full comprehension, however, of the invention, reference must be had to the annexed drawings, in which like symbols indicate corresponding parts, and wherein Figure 1 is an elevation of the expanding mandrel; Fig. 2, a-longitudinalsectionthrough same; Fig. 3, an end view of same, as shown in Fig. 1; Fig. 4, a similar view of same, as shown in Fig. 2, and Figs. 5 and 6,transverse sections, respectively, on lines D D and D D, Fig. 1.
A is the spindle, having cast in one with it in a position to one side of the center of its length a conical body F, tapering outward from its inner end to a screwed end portion of the spindle. The remaining or opposite end portion of the spindle is also screwthreaded toreceive a conical body F, tapering in like manner to that of F, outward toward the end of the spindle, and pierced and screwthreaded to travel along it. Each of these cones F F has longitudinal dovetail grooves ff (preferably three in number) in their outer surfaces to receive head-pins Z) I) projecting from the under sides of adjustable segments or wedgesB B B. These wedges are preferably the same length as the cones and are shaped to makeup the difference between the conical and cylindrical form of mandrel' c. e., their interior surfaces are beveled and their exteriors parallel or horizontal. In order that these wedges shall be more easily adjusted, I make the head-pins b I) in size just sufficient to hold them loosely in place, and use loose washers E between their outer ends and the nuts 0 O, traveling on the screwed portions of the spindle, to secure a steady inward pressure.
Heretofore the connection between wedges and cones has consisted in making such wedge in dovetail form and introducing it bodily into the dovetail groove in the cone, with the result that the wedgesvery frequently stick in position and entail more or less trouble in adj ustment.
The cone F,with its adjustable wedges, goes to form what I have before called a Sl33.l3l0l1 ary expansiomhead, and the cone F,with its wedges, a movable expansion-head}? and it will easily be seen thatno matter whether the aperture requiring fitting be long or short, conical or cylindrical, my mandrel can be adj usted to suit it and simply by the turning of the nuts 0 O (and the cone F in some cases) in either direction.
If a conical hole is to be fitted, it is only necessary to locate the wedges near the outer end of one of the cones and move inward those on the other cone, thus securing different diameters.
\Vhat I claim is as follows:
1. In an expanding mandrel, the combina tion of a spindle, a stationary expansion-head, a movable expansioirhead, and means for expanding the heads, as set forth.
2. In an expanding mandrel, the combina tion of a screwed spindle, a stationary cone surfaces and iitting such grooves, so that such wedges are adapted to be adjusted longitudinally along said cone with their said under surfaces in contact with the said exterior surface of same, and a traveler on such spindle for eii'eeting such adjustn'ient, as set forth.
August 29, 1890.
