PlCKER-ROLL FOR HATTING AND FUR-REFINING MACHINERY.
SPECIFICATION forming part of Letters Patent No. 761,170, dated May 31, 1904.
Application filed October '7, 1903.
To all whom it may concern.-
Be it known that I, LEWIS R. HEIM, a citizen of the United States, residing in Danbury, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Picker-Rolls for Hatting and Fur-Refining Machinery, of which the following is a specification.
- This invention relates to the construction of rolls studded with pins for use in the class of'machinery indicated in the title and, indeed, for any use where a roller of this general character is required. Rolls of this kind have had a Wooden core or body mounted on a metal shaft and covered with a relatively thin cylindrical metal shell perforated to receive projecting metal pins; and the object of the present invention is to construct the Wooden core or body of the roll in such a manner that it may be made and applied to the metal shaft at a moderate cost and so that it will remain fixed firmly and securely in place thereon, although subjected to hard usage and to variable'hygrometic influences.
In the accompanying drawings, which illustrate an embodimentof the invention, Figure 1 is a longitudinal axial section of the roll. Fig. 2 is an end View thereof. Fig. 3 is a cross-section at m in Fig. 1.
l designates the metal shaft of the roll, on which is fixed the wooden core or body composed of two sections 2 2. Covering the Wooden core is a cylindrical metal sleeve or shell 3, perforated to receive the numerous picker-pins 4, which are driven into the wooden core. In constructing the roll a hole is drilled through the shaft 1, preferably about the middle of the length of the roll, and in this hole is driven a tightly-fitting metal pin 5, which will be, by preference, pointed at its projecting ends. The wooden core in two longitudinally-divided sections is grooved out so as to form an axial bore to fit the shaft snugly and is turned to form a cylinder of the proper diameter to fit snugly in the metal shell 3. Glue'or cement is applied to the shaft and to the flat faces of the woodensections 2, and they are made to fit together and embrace the shaft, being held pressed firmly until the glue or cement has set. In pressing the sections together on the shaft the ends of the pin 5 lr 'al No. 176,027. (No model.)
are made to enter the wood of the sections, and said pin serves to prevent any possible endWise movement of the core on the shaft. After the core is fixed on the shaft it may, if desired, be trued up in a lathe. The wooden core is now provided with -coned clampingrings 6, one at each end. These rings or bands are cylindrical exteriorly and of the same diameter exteriorly as the core; but they are slightly coned interiorly, as seen in Fig. 1. The rings are driven onto the ends of the core and compress the wood upon the shaft. It is preferred to make the rings 6 rather thick and strong and to form on the wood of the core by turning a reduced and slightly conical portion to receive the ring; but the intention is to have the ring fit so tightly as to compress the wood and to require considerable force to drive it on. any danger of looseness from shrinkage or from the giving way of the cement or glue. By glue as herein used is meant any of the well-known substances for cementing parts together. There may be more than one pin 5. Having thus described my invention, I claim 1. A roll for the purpose specified consisting of a metal shaft, a sectional wooden core having its sections glued together and to the shaft, coned metal rings tightly embracing the ends of said core and compressing the wood thereof, a metal shell embracing said core, and picker-pins set in said core and shell.
2. A roll for the purpose specified, consisting of a metal shaft, a sectional wooden core embracing said shaft, coned metal rings tightly embracing the ends of said core and compressing the Wood thereof, a pin 5 extending transversely through the shaft and its extremities penetrating the respective sections of the core, a shell of metal embracing said core, and picker-pins extending through said shell and into said core.
In witness whereof I have hereunto signed my name, this 5th day of October, 1903, in the presence of two subscribing witnesses.
' LEWIS R. HEIM.
These rings obviate
