POWER BOLLEB.

A plicati n fiied February 25,, 1 927. 'saai No. 170,917'.

This invention relates to a power roller for'usein connection with headers, combines and 'other' harvesting machinery devices wherein elevator canvas' is operated. Power rollers for the purpose 'aforesaid are ofthe compostetype, metal and wood,

' to properly e levate and rotate the canvas,

whichjcarries the cut and headed grain.

Theordinary power roller for the purpose aforesaid and now in general use comprises a wooden body portion, *a metallc shatt and lateral cross bars or rivets engaging the shaft, andwith one`or 'both opposite ends of the cross bars riveted 'through the wood body and the latter is constructed of two Sections. This 'formvof power roller is open to. a' serious objection, in that, experience shows that the constant pressure and vibration shears' or breaks off the rvets, releasng the coupling connection between the shaft 'and wooden body 'portion and causes more or less constant trouble, and to overcome this -troublesome feature, is the primaryobject of the invention, and therefore theinvention has for itsobject, to provide in a manner as hereinafter set forth, a power roller which will 'be rigid, will not be affected'by vibration, will stand the strain and stress; will materially facilitate the distribution of service when rotating and elevating the canvas'by reason of thei power thrust upon the roller,,and' further to avoid the usual' breaking and shearing of the rivets or pins now commonly'used. a

Further objects of the' invention are to provide, in a manner as hereinafter set forth, a power roller for the .purpose referred to; 'which is simple in its 'construction and arrangement, strong, durable, rigid, Compact, thoroughly eflicient in its use, readily assembled and comparatively' inexpens ve to manufacture. V l V With the foregoing. and other objects in view the invention consists' of the novel construction, combination and arrangement of parts as hereinafter more specificallyde scribed and 'illustrated in the accompanying drawings, wherein is shown an embodi-j ment of the invention, but 1t is to be' under-,

stood that changes, variations and modifications can be resorted to, which fall within the scope of the claims hereunto appended.

In the drawings wherein; like reference Characters denote corresponding parts throughout the'sever'al views: V

Figure l is a fragmentary view, in elevation, of a powerf roller in accordance with this invention. f v Figure 2 's a 'cross Sectional- View of a ,power roller in accordance with this invention of a'modified form and with the section taken between the transverse median and 'one end of the roller; I

Figure 7 is [a cross 'sectional'view, of the form of power roller shown in Figure 6' and 'taken at the tr'ansverse median of the roller.

A power roller,-in accordance-with this invention, comprises a body-portion formed of two like Sections ,1, 2 of semi-cylindrical cross section and constructed of material other'than metal, preferably wood. The in- ,ner face of each section of the body portion of the roller is formed with a semi-'Circular groove 3 at .the longitudinal median thereof and extending' from one end to the other end of the section. The section at its trans- 'verse median is formed with an opening extending from the outer face of 'the section and communicating 'with the groove 3. The section is furthermore provided in proX- inity to each' end thereof with a transverse opening extending from the outer face of thesection to the tgroove v3 and the said 'openings are indicated at 5, 6. Between the openngs 4 and 5 and in proximity to the opening 5, the inner face ofthe section is formed with a pair of transversely extending, opposed spaced grooves 7, 8 and the section between the openings 4 and' 6 and in proximi'ty to the opening 6 is formed with a pair of transversely extending, opposed spacedgrooves .9, 1 0; The grooves 7 to 10, inclusive are formed onpthe nner face of 'the section and. extend'from the outer face thereof tofthe groove 3. The baseof each of the grooves 7 to 10 inclusive, diverge in a directiontowards the groove 3 and merge into the wall of the latter. The diverging part ofthe base of each of the grooves 7` to 10 is indicated at 11 and shown in Figure 2. The portion of each of 'the grooves 7 to 10 other than the diverging part of the V.

base thereof extends in the same plane throughout as indicated at 12. The grooves '7 to of one sectionoppose thegrooves member, carried on a shaft of the'roller and 16 of the shaft 14. The openings 4 of the which will be presently referred to. Each socket in cross section, is of rectangular contour with respect to the form shown in Figures 1 to 5. The outer .end of each of the openings' 4, 5 and 6 is enlarged, as indicated at'13 Figures 2 and 3.

The metallie shaft is indicated at 14 and in cross section, conforins in contour to the opening formed by the grooves 3 when the sections 1 and 2 are secured in abutting relation. As shown the shaft 1 1 is of cylindrical cross section and is provided centrally thereof with a diametrically extending opening 15 which registers with the openings 1- of the sections 1 and 2. The shaft 14 in proxmity to each end is provided with an opening, and which openngs are indicated at 16, 17 and align respectively ,with the openings 5 and 6 formed in the sections of theroll body; The shaft 141, be-

tween 'the openings 15 and 16 is provided' with a pair of integral, laterally extending and oppositely disp'osed coupling members 18, '19, and theshaft 1 1 between the openin s 15 and17 isprovided with a air of integral, laterally extending oppositely disposed coupling members'20, 21.- Each-of said coupling members conforins in contour to theshape of a socket formed by the pair of opposed grooves 7 or 8, or 9 or 10. The coupling members have their positioned inwardly With respect to the periphery ofthe body of the roller or in other words the coupling members are of less length than the length of the sockets, but are of a size to snugly engage the walls thereof. As the sockets are of rectangular cross section, the coupling members are of like contour.

The ' sections 1 and 2 are secured together in abutting relation, andin enveloping position with respect to the shaft 14, by clamping` members 22 and each of which consists of a headed bolt provided with'a clamping nut. The bolts extend through the openings 4, 5 and 6 of the body section and through the openings 15, 16' and 17 of the shaft lt. The openings 5 of the body sections align and also align with the openings body Sections align and also align with the opening 15 in the shaft, and the openings 6 of the body sections also align and align' with the opening 17. The enlarged portions at the outer ends of the opening provide shoulders 23 and 2% and ,abutting against the shoulders 23 are the heads of the outer ends bolts and abutting against the. shoulders 24' are the' clamping nuts. The bolts are of less length than the diameter of the body portion and when the Sections of the latter are secured in abutting relation the heads of tae bolts, as well as the clamping nuts,

are arranged inwardly with' respect to' the;

outer periphery of the body portion.

The construction illustrated in Figures 6 and 7, is the same as that referred to in ,connection with Figures 1 to 5, with thisx larged as at 28'to provide 'shoulders 29 and against which iabutrclamping nuts "30, car

cried onthe threaded outer end 26 ofthe coupling members 25. Otherwise than that as stated the construction shown in Figures 6 and 7, is the same as that shown. in Figures 1 to 5 and corresponding parts are "provided with like reference characters.`

The construction of the power roller, in

accordance with thisvinvention',' provides a rigid roller that will not be eifected byv-ibration, will stand the strain and stress, will materially facilitate the distribution of V service in rotating and elevating'fcanvas by reason of the power thrust upon thefroller and further will avoid the usual breaking and shearing of therivets or pins now present inthe ordinary type of power roller used, and therefore it' is thought the many advantages of 'a' power roller, in accordance wit-h this invention, can be readily' understood, and although the preferredvembodiment ofthe invention is as ,illustrated and described, yet it is to be understood that changes in the details ofconstruction ean be had which will fall within the scope of the invention' as" claimed. r
