H. FREEMAN & J. ARMBRUSTER.
Steam-Boiler Flu-Scrapers.
Patented Dec. 3,1872.
S L S 5 E N T UNITED STATES PATENT HIRAlVI FREEMAN AND JACOB ARMBRUSTER, OF PETROLEUM CENTRE, PA.
IMPROVEMENT `IN STEAM-BOILER FLUESCRAPERS.
Specification forming part of Letters Patent No. 133,5?3, dated December 8, 1872.
.To all whom t may concern:
Be it known that we, HIRAM FREEMAN, of Petroleum Centre, county of Venango, State of Pennsylvania, and JACOB ARMBRUSTER, of the same town, county, and State, have jointly invented a new and Improved Flue- Cleaner; and we declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use it, refer-V ence being had to the accompanying drawing which forms a part of this specification.
Our invention relates to the construction of a flue-scraper with two longitudinal springs and lateral rings or bands so united that all parts of the due will be thoroughly scraped at the same time, and to other items in the construction of same.
In the drawing, Figure l is a plan of the flue-cleaners, in which A are springs; B are segmental cylindrical plates, bearing guides O which come up to the surface of the scrapers D B' B", &c.,'are .similar plates; and D' D", Ste., are similar rings or Scrapers. Plates B' unite along slot .fr y. Plates B" and B' lap over each other. G are pivots in grooves or slots F. I is rubber packing supported by metal plates J and retained by nut K on bolt L.
Fig. 2 is section, in which similar letters represent similar parts. m man m is section of boiler -iiue The plates B' B", `&c., are pressed together, and the rings D D', Ste., press against the iiue on all points. The springs in pressing together have forced the pivots Gr into the extreme ends of slots F. h h, te., are pivots by which the plates are attached to the springs. E is acontinuous rod of iron or other metal.
Our invention consists as follows: We take two pieces of Springsteel, A A, curved as shown in the drawing, and to these pieces of spring metal we attach Scrapers B B' B", Snc., by means of rivets passing through the plate and spring. The plates B are segments of a cylinder. A second plate, n a, Fig. 2, is riveted to this plate, whose edges projecting upward form the guides O G. These guides come up flush with the top of the ring D, so that when the cleaner is forced into a flue the springs will be pressed together, and the guides C will prevent the flue from catching on the ring D as the latter enters. The second plate B is similar to the first but is slotted diagonally at w y on both sides, and has a ring on both ends of the plate at D D'. This diagonal slot is for the purpose of prevent ing the possibility of any part of .the flue not being scraped by the rings D' D'. The plates B" B' are similar to the last, but instead of the slot one of them is made to lap over the other at its ends to eiect a similar purpose. The springs A A, unless allowed to yield at the ends, would break when cramped into a flue. We therefore provide slots F at their ends in the arm E through which the pivots G G pass, and in which they are permitted to slide freely. When compressed in a tube they will assume the position shown in Fig. 2. At the lower end we attach a piece of rubber packing or other similar substance, retained by a bolt, K,- between two plates or disks, J J, for wiping out any material that is loosened by the rings or scrapers. At the other end we form a screw-head, into which the rod or handle is screwed.
We know that the rubber cleaner I I has been used before. Ve do not, therefore, claim that feature except when combined with the other parts of the cleaner herein described. We know, also, that springs have been used for a similar purpose. We do not therefore claim them broadly. This may be used by dispensing with either the diagonally-slotted ring or the lap-ring, and slots F F may be dispensed with by forming a mortise-and-tenon joint, Z Z, shown by dotted lines in Fig. l.
Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-
l. The flue-scraper herein described, composed of springs A A, plates B B with guides C O and Scrapers D D, diagonally slotted plates B' B' with scrapers D' D', or lap-plates B" B"' with scrapers D" D', arm E with slots F F and pivots G G, screw-head L, and wiper I I, constructed, arranged, and operating substantially as described.
2. In a flue-scraper, the diagonally'slotted plate B' B', substantially as described.
3. In a luescraper, the lap-plates B" and B', substantially as described and shown.
