TO ALL WHOM IT MAY CONCERN:
Be it known that I, E. J. MOQRE, 'of East Bost-on, in the county of Suifolk, and State of Massachusetts, have invented a new and useful Improvement in TubefExpanders; 'and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skillcdin the art to make and use the same, reference'being had to the accompanying drawings, forming part of this specification.
This invention consists in 4arranging astock with a number of rollers placed therein, with beads formed on them, which rollers are so adjusted in the stock that'they canv be pressed outward by a tapering pin, which passes through the stock, and operates upon ,the rollers in such a manner that the process of setting tubes-in a steam-boiler is greatly simplified, and rendered easy in situations where it couldnot be performed in the ordif nary way, as I will proceed to describe. In the drawing-` Figure 1 represents a longitudinal section of the tool, through the line y y of fig. 2, showing the arrange-V mentof the rollers and the tapering pin, with one o f the rollers detached; also a section ofthe boiler-tube and tube-sheet in red.
Figure 2 is a eross-section of fig. 1, through the line n: m. Similar letters of reference indicate like parte. l p represents the stock; B the tapering pin and screw. C represents thc rollers; D the handle or lever on the pin B.` The shape or formation of the stock is clearly seen in the drawing. The rollers are plaecdin recesses from within the stock, and are guided by pivots on their ends, which work in slots in the stock.` When the pin B is removed the rollers are readily taken out. The upperA portion or head of'the sto'ck has a screwthread cut in it, and the upper. portion of the pin B has a screw-thread upon it which lits the stock.V The sides i ofthe screw part of the pin are parallel to each other.
The operation is at once understood from the drawing. As the pin is turned or secured into the stock, the tapering 'portion forces the rollers outward, the beads on the rollers indent t-ho tuhe upon each side'of the head or tube-sheet, thereby forming a groove around'the tube, which holds it securely to its4 place in the sheet. It will be noticed that the bead on the upper end of the roller is smaller in diameter than -the other. This l is for the purpose -of accommodating the surface or peripheries of the beads to the shape of the tapering pin.. The hole through the tube-sheet is usually countersunk, and when tubesare sot by my plau,`or with this i. expander, no caulking is required, and the tubes are much less liable to be injured by fractures or otherwise than when they are set in the ordinary way. Tubes can be set with this expander, in case of p repairs 'or othcri wisc, where a hammer or sledgc could not be used for driving in the pin, according to the common method.
I am aware of the patent granted to R. Dujdylon', dated February 5, 1867, for a tube-expander,` but this f.
I do not claim, as it forms no part of my invention, but what Ilclaim as new, and desire to secure by Letters Patent, isi l 4 i v ,l
The construction'ofthe expanding-rollers C, provided with beads surrounding their peripheries, the lower one of less diameter than the upper, substantially as described for the purpose specified.
