TA W OTTO A. SGHAMELL, OF MILWAUKEE, WISCONSIN.
ROAD-ROLLER.
To all whom it may concern:
Be it known that I, 0110 A. Summon, a citizen of the United States, and resident of Milwaukee, in the county of luilwaukee and State of Wisconsin, have invented cer tain new and useful Improvements in Road- Rollers; and I do hereby declare that the following is a. full, clear, and exact description thereof.
My invention refers to road rollers, its primary object being to provide a snnple' and economical roller of this type, whereby efficiency is materially increased, the construction and arrangement being such that a series of three or more rollers in progressive advancement are provided, which set of rollers may constitute a complete machine or a series of such sets or groups may be assembled to form a complete machine.
By arranging a front and rear roll with one or more intermediate rolls therebetween in successive order as stated above, the surface of the road acted upon it subjected to a series of independent ironing pressures in quick succession as themachine travels a distance approximately equal to the distance between the'first and last-roll of the series, the number of ironing pressures being equal to the number of rolls with which said machine is provided. Hence it is apparent that should the road-bed worked upon contain a series of waves within the distance between the first and last roll of the machine, each one of said waves will be subjected to a series ofimpressions, whereby they willbe reduced to a common plane. a
It follows that a further advantage of my construction lies in the fact that the machine traveling once over a road-bed will equal'the work accomplished through an ordinary type of machine moving overthe same distance many times, the saving in repeated rolling operations being equal to the number of intermediate rolls utilized, it being apparent that the result of a road finished in accordance with my invention would be of such uniform smooth finish as to make it possible for any vehicle to pass over the road or pavement without being jarred or otherwise disturbed, which jarring effect results when the road is finished in waves or uneven surfaces by machines equipped with a single pair of rolls. Furthermore by increasing the number of rolls or the effective area of the machine comprising the multiple contact points a single Specification of Letters Patent.

flat surface is approximated as ,a result of one-operation of the machine. This finished result is due to the fact that the action upon the peaks of the waves will cause the same to fill up the recesses therebetween by flow of. the material and this material flowing into the recesses would also be subjected to the primary pressure, ,whereby when the road 1s completed its surface is of uniform deus1ty andv its wearing resistance will be accordingly uniform.
Heretofore it has been thejpractice to I utilize machines forroad construction having' only two sets of rolls one inadvance of the other with the axis of each set at such distance apart as to support the structure, which structure necessitates considerable wheel base. The result of a two point contact wheel base necessarily causes a considerable space between the ground contact points of said rolls and hence when machines of this type are at work it is obvious that the road surface when finished will present more or less a series of horizontally disposed waves due to the fact that the road material tends to bill up in advance of the rollers and under certain conditions this road 'material will set in the above mentioned waved or uneven condition before the machine could repeat its travel thereover.
-Hence with the ordinary type of roller-the material is subjected to the pressure of one roll and after a considerable length of time the said material is subjected to a second pressure, but, as stated, these distinct pressures spaced apart are not suflicient to iron out or overcome the defective waves. ideal manner for constructing roadways of concrete, asphalt or analogous material would be to submit the surface to a uniform simultaneous pressure, whereby all waves would be avoided, but a machine for accomplishing this result is, so far as I am aware, impractical. v
While I' have mentioned that primarily my invention comprises the application of an intermediate roll between front and rear rolls in practice it is proposed to construct a machine having a series of intermediate rolls, whereby the objectionable features mentioned of the ordinary type of road roller are overcome, it being understood that The n the axis of the several rolls of the series are arranged as close together as practical, whereby the road materlal is sub ected to a quick succession of rolling impressions in independent a flat horizontal plane,
such manner that it is worked or rolled into a flat mass of uniform density irres ective of the material which is utilized in t e con-v struction of the surface or base of the road.
With the above object in view the invention consists in certain peculiarities of construction and combination of parts as set forth hereinafter with reference to the accompanying drawings and subsequently claimed.
In'the drawings Figure 1 represents a sectional plan view ofa gang of rollers arranged in accordance with my invention; Fig. 2, a side elevation of the same; Fig. 3, a plan view of a gang or group of rollers arranged to break joints with each other, whereby longitudinal seaming is avoided, and Fig. 4, a diagrammatic side elevation of a machine of rolls.
Referring by characters to the drawings, 1 and 2 represent front and rear rolls of a machine, which rolls are journaled in a frame A and interposed between the front and rear rolls are a series of intermediate rolls 3, 3. The said series of rolls are flanked by two series of three rolls 4, 5 and 6, the axes of which flanking rolls break joints With the axes of the center .set. It is understood, as indicated by dotted lines, that each of these series may be extended indefinitely to form a single machine, or, as shown in Fig. 4, two gangs or groups of rolls may be utillzed.
Referring to Fig. 3 of the drawings, I have illustrated diagrammatically a series of rolls wherein 7 indicates the rear roll and 8 the forward roll, the said rolls being built up by independent axially alined sections. Interposing the front and rear rolls 7 and 8 are intermediate sectional rolls 9, 10 and 11, the sections breaking joints with succeeding sections, whereby longitudinal seaming in the surface to be worked upon is avoided.
As indicated in Figs. 2 and 4 the contact I faces of the series of rolls are arranged upon but it is understood provided with two sets or groups that in some instances, if desired, the contact points of the rolls may be varied longitudinally of the series, so as to form a slight convexed or concaved surface line. It is also within the scope of my invention to vary the shape of the rolls longitudinally as, for
exam Ie, the same may be formed from conica sections in such manner that the com blned transverse sections W111 present a .tance equal to the distance between the axes of the first and last roller, the surface worked upon, will be completely ironed out three times, the ironing pressures being in quick succession will thus prevent wave accumulations, it being manifest, of course, that the greater number of intermediate rolls within limits, the greater the efficiency of the work and speed.
I claim:
l. A road-roller comprising a rigid frame,
a pair of independent trucks pivoted thereto,
each truck having rigidly mounted therein a front and rear roller and an intermediate roller.
2. A road-roller comprising arigid frame, a pair of independent trucks pivoted thereto, each truck having rigidly mounted therein a series of three or more alined rollers.
In testimony that I claim the foregoing I..
have hereunto set my hand atMilwaukee in the county of Milwaukee and State of Wisconsin in the presence of two witnesses.
