ROLLER FOR ROAD SURFACES AND THE LIKE Filed June 21, 1956 ll I' 38 4 2' Sheets-Sheet 2 80 A rm/wfy;

nits ttes My invention .relatesto improvements in machines for rolling roads, driveways, tennis courts, parking areas and like surfaces and more particularly for use when an all weather material is being applied to such surfaces.

Present surface rolling machines are constructed so that the rollers cannot be maneuvered flush with a curbing or the like that may border or divide thearea on which the roller is used and as a result a strip approximating a foot in width must remain adjacent such curb untouched by the roller. Hand tamp-ing is required to finish this strip and in addition to the extra labor costs involved to the contractor doing the work, it will be appreciated that such hand tamping does not always compress this strip to a level plane with that part of the area subject to compression by the heavy roller. A machine that would thus cover all the area up to the curb would not only save costs in operation but would produce a more efiicient and satisfactory result.

With these observations in mind it is one ofthe important objects of this invention to provide in a surface rolling machine novel structure for suspending one of the rollers so that it may move immediately adjacent a curb or the like.

More particularly the instant invention contemplates the provision of novel means for mounting the steering roller in an off set position relative to the chassis or body frame so that it projects laterally from one sidethereof.

A still further object of this invention is to provide a roller of the above class .in which all supporting structure for the off set roller is disposed at the opposite side of its projecting end.

Still another object inhering in this invention :is the provision of means by which the ofi set roller may be of the split roller type.

Other objects and advantages of this invention reside in the details of construction and correlation of the various parts and will be apparent as the description proceeds.

This invention consists of novel parts and combination of parts to be hereinafter described whereby the objects set forth are attained, as pointed out in the claims, and illustrated in the accompanying drawings, in which:

Fig. 1 is a perspective view of a roller machine showing my off set roller and mounting arm therefor, said roller being of the non water filled type,

Fig. 2 is a cross sectional view taken on the line 22 of Fig. 1 to show the means for attaching the mounting arm to the roller and to the body,

Fig. 3 is a cross sectional view of part of the mounting arm taken on the line 33 to show its interior constructron,

Fig. 4 is a cross sectional view of the mounting arm taken on the line 4-4 of Fig. 3,

Fig. 5 is an end view of the roller from the attachment side of the mounting arm, and,

Fig. 6 is a longitudinal sectional view of a roller designed to be filled with water and showing my mounting arm adapted for use therewith.

Referring to the drawings a chassis or body 10 is shown atent '2 (Fig. l) carrying a rear or .compressionroller 1 2. "A suitable motor (not shown) is usedfor propelling thls'machine and steering means .14 is provided in a'well known manner. No invention is ..cl-aimed in such parts'which are shown to illustrate the general setting in which my new mounting arm, indicated generally at 16, is used with the forward or steeringroller 18 which is of'common construction being of the split type having the adjacent sections 20 and 22. Each section 20 and 22 has the internal ring or plate 24 and 26 respectively on the outer .side of' which relative to the outer side of the rollers 20 and 22 are the gussets 28 and 30 respectively for supporting the roller surfaces in a well known manner.

Roller 18 is mounted to the body 10 in a laterally ofi set position (Fig. 2) by my new'mo-untin'g arm-16 which comprises a horizontal member 32 and a downwardly extending member 34 at one endin an inverted reverse L shape. Projecting from the lower end of portion 34 in the same direction as and parallel to portion '32-is a spindle member 36 integrally secured to portion 34 by means of a sleeve 46. This arm--16 is substantially square in'cross section and crisscrossing diagonal internal braces 38 are provided in the horizontal portion 32 (Fig. 4) with an internal gusset 40- extending between the two portions 32 and 34 at the corner 42'. An external gusset or Weblike brace 44 is placed between portion 34 and the inner supporting structure 46 for the spindle 36 so that adequate strength is provided for all stresses and strains to which the arm 16 may be subjected in use.

The free end of arm portion 3-2 (Fig. 2) is attached by suitable spindle means 48'to the center'portion ofthe body 10'so that it may turn easily and rock laterally on surface irregularities. Mounting 48 issimilar to usual vehicle wheel mountings and no invention :is claimed therefor. A steering lever 50 projects beyond arm portion 32 and is operatively connected by cable or the like 52 to the steering-mechanism 14. In mounting the roller unit 18 to arm 16, the spindle 36 passes through an axial opening in plate 26 within roller section 22 (Fig. 2) and is 'journalled in :a hub 53 mounted on the inner sideof such plates by the bolts '54. vNut'56 securesthe outer vend of spindle 36 as shown. Hub 53 may be of-anysuitableztype and it will be understood thatit has properbearingsfand grease seals as is usual in 'wheel mountings.

To mount roller section 20 in axial alignment with section 22 I provide a tubular housing 58 :having aplurality of radially extending braces 60 corresponding in number and position to the spacing of bolts 54 on hub 52. Braces 60 are attached to hub 53 by'means of bolts 54 (Fig. 2) so that housing 58 is spaced from and in axial alignment with spindle 36. Housing 58 terminates in an integrally secured spindle 62 of the same type as spindle 36 and is journalled in a hub 64 attached by nuts 66 to the outer side of plate 24 in roller section 20'. Nut 68 is used in the same manner as nut 56. Roller sections 20 and 22 are mounted by means of hubs 64 and 53 on respective spindles 62 and 36 to form a space 70 between said roller sections, which space it will be noted is in vertical alignment with spindle assembly 48 and thus allows full advantage in the use of split rollers as they rotate independently of each other in negotiating a curve.

Thus constructed, roller 18 is adequately supported by the single arm 16 at one side thereof and the opposite end of roller 18 as viewed at the left in Fig. 2 is not only cit-set relative to the corresponding side of body 10, but is not hampered by any supporting arm or frame that will interfere with its moving closely adjacent a curb, wall or the like. As a result the surface material can be machine rolled right up to the curb so as to leave nothing for hand tamping and will of course a sleeve 81 having a bore 82 (Fig. 6).

jcompartments 74 and 76 in the respectiveioller sections 78 and 80 I have adapted my arm 16 for mounting thereto as follows. Spindle 36 (Fig. 4) has been removed and the lower end of portion 34 is provided with 84which is found in such rollers is elongated to provide the extension section 86 that is rotatably journalled in opening 82 and secured to the outer side of arm portion 16 by a nut 88. In all other respects the arm 16 is the same and roller 72 is mounted in an oft-set position relative to body as described above. Both water filled and nonwater filled rollers are commonly used and I have thus designed arm 16 for use with both types.

It is submitted that the invention shown and described -is aptly suited to achieve the purposes intended and is characterized by a combination of highly useful and mutually cooperating elements that combine their respec tive and proportionate functions in accomplishing the objects sought to be obtained.

It will be understood that the phraseology employed herein is for the purpose of description and not for limitation and that modifications and changes in the construction and arrangement of this invention can be made within the scope of what is claimed, without departing from the spirit and purpose thereof. It is thus intended to cover by the 'claims, any modified forms of structure or mechanical equivalents which may be reasonably included within their scope.
