IMPROVEMENT m ExPANome MANDRELSV Specification forming part of Letters Patent No. 180,169, dated July 25,1576; application filed June 28, 1876.

To all whom it may concern:

Be it known that l, STEPHEN P. M. TAS- KER, of the city and county of Philadelphia, in the State of Pennsylvania, have invented a new and useful Improvement in Expanding Ma-ndrels, which improvement is fully set forth in the following specification, reference being had to the accompanying drawings.

The nature of my invention consists in the division of the mandrel into tapered longitudinal sections, the wide end of every alternate section being at one end of the mandrel, and the wide end of the intermediate sections at the other end. The edges of the sections eter, and when they'are moved in an opposite direction the diameter is expanded. In order to accomplish these results, so as to accommodate themandrel to difl'erent sizes of tubes, I connect the large endsof every alternate section with a flange held thereon by means of screws or pins, which are allowed play in radial slots, the said flange being fast on' a central rod. The large ends of the intermediate sections are in like manner connected with a similar flange, which is fast on one end of a central tube or socket. The rod is operated by means of a nut on its outer end, or by a lever or any other suitable device, whereby the mandrel is expanded or contracted in the direction of its length, .for the;

A A A are three tapered longitudinal sec-.

tions of the mandrel, and A A A are intermediate sections of the same form, but in a reversed position, whereby their narrow ends come between the broad ends of the former. The broad ends of the sections A A A are held against the flange B by means of screws 'or pins 1), there being radial slots 01 in the flange to admit of the expansion and contraction of the sections. Thesections A A A are connected in like manner with the flange. B by means of the screws I), which pass through the radial slots d of the flange. The'sections are held together by means of the male and female dovetails e 6, whereby they are permittedto move freely in the direction of their'lengths, for the expansion and contraction ofv the mandrel, and their peripheral surfaces kept at all times even with each other.

, G is a central 'rod, one end of which is permanently connected with the flange B. It. has a longitudinal movement in the tube or socket D, one end of which is fast to the By the longitudinal movement of the rod in thedirection of the arrows seen in Fig.1, the two setsof sections. A and A having their wide ends drawn nearer each other, the mandrel is expanded in its diameter, as seen-in said Fig. 1; andwhen therod is moved in the opposite direction, (indicated by the arrowin Fig. 5,) so as to cause said broad ends to recede from each other,

the diameter is contracted, as seenin said To effect the longitudinal movement of the rod C have a nut,f, on its outer end, as represented in the drawing, or else employ a lever or any other convenient device, whereby a like result is produced.

I have shown three sections in each set,

but do not confine myself to the use of this number, as two or any higher number may be used.

The combination of the rod 0 and tube D may be dispensed with by having a rod proexpansion and con raction of the diameter of or socket D with the flanges B and B and the mandrel, substantially as set fort-h. sections A and A, the rod being operated 2. The combination of the sections A and by means of the nutfor other suitable device,

A, having screws or pins 11 b in their ends, substantially as set forth.

with the flanges B and B, having radial slots STEPHEN P. M. TASKER. d d, substantially as and for the purpose set Witnesses: i forth. THOMAS J. BEWLEY,

3. The combination of the rod 0 r and tube STEPHEN USTICK.
