Application filed July 9, 1907. Serial No. 382,858.
VTo all whom it may concern:
Be it known that I, HENRY BRUBAKER,
The. present invention consists of certain` new and useful improvements in rollers.
One of the objectsof the invention is to provide a roller which may be built up from strips or sections of wood.
Another object is to provide a novel means for holding the strips Vin a cylindrical form.
A further object is to provide a novel form of attachmentby means of which the roller may be connected with a source of rotary power.
` Other and further objects and advantages of the invention will be apparent from the following detailed description, pointed out in the claims, and illustrated in` the accompanying drawings.
Referring to the accompanying drawings, in which like characters of reference refer to corresponding parts,-Figure 1 is a perspective viewof the roller. Fig. 2 is a longitudinal sectional view thereof. Fig. 3 is a perspective view of the supporting frame, the same being shown detached from the roller. Fig. 4 is a detail view of one of the strips.
The roller forming` the present invention may be used in connection with various types of roller machines and is of special utility in the printing, paper making, textile and kindred arts. In such machines the rollers are used for various purposes, such as printing and embossing, pressing, burnishing and conveying. And in order to provide a roller that may be used for any of the above or analogous purposes, it is necessary that the roller should be made of strong material to withstand the varying pressures and strains incident to a rapidily rotating roller. And also means must be provided which will permit of the roller being readily connected with the source of power of the machines.
It has been found in the practical use of rollers for machines as specified above, that it is necessary to reinforce them in order to stand the strains and pressures to which they are subjected, and in order to provide a satisfactory structure, the present invention has been designed, which structure is described and illustrated in its preferred embodiment in the following detailed description and accompanying drawings.
Referring to the drawings, 10 designates a roller in its entirety, which is composed of a plurality of longitudinal strips 11 of wood. Said strips 11 are turned in a lathe or the like, to provide a conveXed outer surface and a concaved inner surface, and their longitudinal edges are inwardly inclined, to provide a wide outer surface and a narrow inner surface, the arrangement being such that when the strips are assembled with their' longitudinally inclined edges 12 abutting one another, a cylinder will be formed. Referring more particularly to Fig. 4 of the drawings, it will be observed that the lower corners of the inclined longitudinal sides of the strips 117 are cut-away to form one half of a longitudinal recess which, when the strips are assembled in cylindrical form, form longitudinally extending recesses 14, provided with a bottom wall 15 and inwardly inclinedend walls 16, 17. The supporting frame 18 comrpises aplurality of spacedapart longitudinal keys 19 arrangedin cylindrical form. The shape of said keys 19 are substantially the same as the longitudinal recesses 14 of the strips 11, and in length they correspond with said strips. 20, designates a metal shell or tube which'supports the keys 19 in the desired spaced apart position, the keys being rigidly held on said shell or tube by means of the bolts or screws 23.
By referring to Fig. 3 of the drawings it will be observed that each end of the shell or tube 20 has located therein a supporting ring 21-22, each of which are provided with wedge-shaped slot or keyway 24, the outer end of which is comparatively deep and from which end its depth decreases until it reaches the inner end, at which point it terminates ush with the inner surface of the said ring or collar. The function of said slot or keyway will be set forth presently.
In assembling the parts in theiroperative position, the rings are placed within each end of the tube or shell and the wedgeshaped keys are then attached to the shell or tube by means of bolts or screws, in the desired spaced-apart position. The strips are then driven in between the wedge-shaped keys, the cut-away portion of each strip snugly fitting over one side and one-half of the outer surface of said keys. When all the wedge-shaped keys, a cylindrical. structure such shown in Fig. 1 of the drawings is formed, in which the strips, by means of theii cut-away inner portions, form a socket, or recess for the reception of the keys, tlie connection therebetween beingk in the form ofY what is known as a dovetail.
To attach the roller to a source of power, the stub end of a power shaft is inserted into the collars in the ends of the supporting shell or tube and may be securely and relatively iniinovably held therein, by means of a key or the like driven into the slot or keyway QA.
From the foregoing description it will be seen that a roller has been produced that is of sections, or strips of wood, and| that by means of the inner supporting tube or shell and the fastening keys carried thereby, such strips are firmly and rigidly held in such a manner as toserve all the functions of a continuous cylindrical roller, and one in which the injurious effects of the centrifugal force incident to the operation of the rollers has beeny obviated. And it will be further understood that by means of theV inner shell structure formed to engage with and iininovably hold the strips or sections of wood in position, all danger of the rol-lerk shrinking will be overcome. And it will also be understood that by means of the screw or bolt connection between the supporting' tube or shell and the fastening ribs, a detachable fastening means is provided which readily permits of the substitution of a new rib for one that may have becomeV broken or otherwise damaged. The tube or shell 20 together with the keys or ribs 19 secured thereto comprise a section holder for the strips or sections 11.k It will be further observed that the keys or ribs 19 are detachable from the tube or shell 20,. thereby permitting of ready replacement of the keys or ribs whenever the same become damaged without involving a substitution of a new tube or shell, or rendering necessary' any change in said tube when ienewing al broken or damaged key or rib. From this it follows that a great saving both in material and time is accomplished, which is a decided improvement in the art, as heretofore the keys or ribs have been made integral with the tube or shell, and hence necessitates an entire new section holder for the strips or sections 11, whenever said keys or ribs are damaged. A
[n the foregoing description and in the accompanying drawings I have described and illustrated a form of my invention that is fully capable of performing the work desired, yet I wish it to be understood that I do not limit myself to thev precise details therein shown and described, reserving for myself any and all modifications thereof as fall within the spirit and scope of the appended claims.
