To all whom it may concern: cleaner constructed according to my inven- Be it known that I, FARMER DoRsEY, a tion. Fig. II is a central longitudinal sec- 55 citizen of the United States, residing at tion of same. Fig. III is an end view of a Hutchinson, in the county of Reno and State cleaner with two of the blades removed.

Mounted loosely and sliuably upon the My invention relates to tube cleaners, and shaft 1, are two heads 3, which are preferhas for its principal object to provide a deably bell shaped and are spaced a suitable vice of that class whereby scale may be cut distance apart. Secured to the outer faces 70 from the inner surface of a boiler or other of and connecting the heads 3 are the blades tube and which is sufficiently fiexible to ob- 4-5, which are preferabl made from spring viate its breaking or jamming in the tube steel, and secured to the eads 3 by rivets 6.
should a solid obstruction be encountered. Each of the blades 4 5 is shaped sub- A further object of my invention is to stantially as shown in Fig. II, from which 75 provide a mounting for the cutter heads it will be observed that the blade comprises that will enable the knife body to flex lon ithe substantially straight end portions 4,

4'0 ing the tendency of the knives to buckle In order to retain the heads 3 on the shaft, when pushed against a protuberance or hard I provide means which may be fixed to the mass of scale. In the preferred form of my shaft and project therefrom so as to engage invention the pulling means may also serve the heads when the shaft is moved in either as a hammer to assist the knife body through direction, such means preferably compris- 45 a tight part of the tube. ing the spring cotters 7 which project Further objects of the invention will bethrough apertures in the shaft adjacent to come apparent from reading the following said heads. As there is a tendency of the description and claims, the preferred form cotters to bend, especially in the small sizes, of the invention being illustrated in the acwhen force is applied, I prefer to provide 50 companying drawin s which bear reference the thrust collars 8, which lit over the shaft numerals correspon ing to the numerals in and have apertures 9 through which the cotthe description, and in whichzters may project to removably fix same to Figure I is a side elevation of a tube the shaft. These collars are so positioned that the distance .between their outer ends is less than the distance between the inner ends 3 of the heads 3, so that the shaft l may have a limited end play without im-v parting motion to either head 3.
In operating the cleaner the parts are inserted in the tube and the rod operated in the usual ways, no skill being required. Vhen the shaft l is moved forwardly, the forward collar 8 will strike the adjacent head 3, thereby driving the blades 4-5 forwardly, so that the forward knife edge 5 will cut the scale.
Now let it be supposed that the blades, or any of them, encounter a heavy obstruction, as frequently occurs. As the blades are outwardly bowed, the obstruction will bend the blade or blades inwardly which will obviously result in elongation of the blade or blades and relative-movement of the rear? ward head 3 away from the forward head. .Supposing `that the obstruction be encountered ,during a rearward stroke of the cleaner: then the forward head 3 will move relatively upon the shaft. Itis thus evident that the blades can not become caught or jammed in any tube.
Should an unusually tight section of pipe be encountered, the end play of the shaft in the knife body will enable the operator to hammer the thrust collar against the knife head 3 to help the device through or along the tube.
The action of the blades in removing the scale will be fully understood without de-4 scription thereof.
Having thus described my invention, what lI claim as new therein and desire to secure `being of spring metal and bowed toward its center, the central portions of said blades being extended diagonally to the end portions and provided with cutting edges.
3.*In a. tube cleaner, a shaft, a. pair of heads movable on the shaft, separate resilip ent blades each having its ends fixed on opposite heads in offset relation to each other and having a diagonally extending section connecting the end parts, the blades being bowed and the edges of the diagonally eX- tending sections being sharpened, substantially as set forth.
In testimony whereof I atlix my signature in presence of two witnesses.
