COMPLETE SPECIFICATION.
Improvements in Street Rollers.
I, BENJAMIN JOSEPH BARNARD MILLS of 23 Southampton Buildings in the
County of Middlesex Patent Agent do hereby declare the nature of this inven-
tion, (a communication to me from Richard Clarence Pope of the City of St. Louis,
in the State of Missouri, United States of America, Mechanic), and in what
manner the same is to be performed to be particularly described and ascertained
in and by the following statement :—
The invention relates to certain improvements in that form of roller shown and
described in United States Letters Patent No. 296,446 issued to the communicator
as the assignee of Charles K. Pickles April 8th 1884.
The invention consists in features of novelty hereinafter fully described and
pointed out in the claims.
Figure 1 is a perspective view of the improved street roller, illustrative of the
invention.
Figure 2 is a detail perspective view illustrating the brake mechanism.
Figures 3 and 4 are detail side views of same.
Figure 5 is a detail axial section showing the dirt guard.
Figure 6 is a detail section, transverse of the arch illustrating the clamp for
holding the frame rigid on the rolls while turning the tongue.
Figure 7 is a detail, vertical section, showing one of the anti-friction_roller
bearings for the journals of the rolls the section is taken on line VII VII
Figure 8.
Figure 8 is a section taken on line VIII VIII Figure 7.
Referring to the drawings, 1 epresents a rectangular frame having heads 2,
one head being located on each side, substantially the same as in the Patent above
referred to.
3 represents the draft tongue, and 4 a swinging frame or beam pivotted to an
arch 5, which spans the rolls, and is secured at its lower ends to the frame 1.
These parts in themselves are the same as the corresponding parts in the Patent
mentioned and act the same, requiring no further description or explanation
here.
6 represents a circle iron or track secured to the arch 5 by brackets 7.
8 represents friction rollers journalled to the beam or frame 4 and which bear
upon the track 6 and move thereon as the draft tongue is being swung around from
side to side of the roller, thus relieving the pivot of the beam or frame 4 from
strain and providing a very easy movement of the beam or frame as it is swung
around.
9 represents the roll or rolls, two are shown. They are mounted on an axle or
spindle 10, with a concave guard or ring 11 between them as shown in Figure 5,
the object of the guard being to prevent dirt and dust, which may fall from the
rolls, from reaching the journals of the rolls on the axle or spindle 10. The ends
of the axle or spindle are journalled in the frame 1 and turn therein, when the
roller is being moved in other than a straight course, and then also, if it is desired
to secure the rolls rigidly to the axle or spindle.
To reduce the friction between the frame 1 and the axle or spindle, housings 13
are employed in which are located anti-friction rollers 14 (see Figures 7 and 8);
the anti-friction rollers are journalled in suitable boxes 14°, shown by dotted lines
in Ho 7

page_text: 15 are springs supporting the lubricating waste against the journals of the
rollers. It will thus be seen that the journal ends of the axle or spindle receive
the entire weight of the frame 1, through the medium of the anti-friction rollers 14,
thus reducing the frictional contact.
When the draft tongue 3 is to be swung around from side to side of the roller
it is desirable to clamp the frame 1 so that it will not move on its bearing with
the journals of the axle 10. I accomplish this by means of a threaded rod 16,
which passes through the arch 5 (see Figures 1 and 6) and which is provided with
a hand wheel 17 on its outer end by which it may be turned, and a block or shoe 18
on its inner end which is adapted to be forced against the rolls 9, and thus hold
the frame from movement relatively to the rolls while the tongue is being
swung around.
19 represents scrapers pivotted to the frame 1, and having extensions 20,
provided with counter-balance weights 21 for regulating the pressure of the
scrapers against the rolls; the object of these scrapers is to keep the rolls free
from dirt.
In going down grades, it is desirable to have a brake on the roller. This I
provide in the form of an eccentric 22 pivotted to the arch 5 at 23 (see Figures 2, 3
and 4).
This eccentric is provided with a number of perforations 24 to receive a bar or
rod 25 by which the eccentric may be moved to bring its inner face against the
rolle, as shown in Figure 4, and thus apply the brake, or the eccentric may be
moved out of contact with the rolls, and held out of contact by means of a link 26,
see Figure 3.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1. In a street roller, the combination of a frame, a roll journalled in the frame,
an arch secured to the frame a circle iron or track, the brackets by which the
circle iron or track is secured to the arch, a beam or swinging frame, pivotted to
the arch, and to which the draft tongue is secured, and friction rollers secured to
the beam or swinging frame, and which bear upon such track; substantially as and
for the purpose set forth.
2. In a street roller, the combination of a frame, two or more rolls journalled in
the frame on an axle or spindle, and a concave guard 11 placed between the rolls
substantially as and for the purpose set forth.
;
3. In a street roller, the combination of a frame, a roll journalled in the frame,
an arch secured to the frame, a beam pivotted to the arch and to which the draft
tongue is secured, and a device for holding the frame from moving on the roll as
said beam is moved on its pivot; said device consisting of a threaded rod passing
through said arch a hand wheel on the outer end of the rod and a block or shoe on
the inner end of the rod; substantially as and for the purpose set forth.
4. In a street roller, the combination of a roller, a frame, a draft tongue adapted
to be swung around to either side of said roller and a device for holding the
frame from oscillating on the roller, while the tongue is being swung around 4
substantially as shown and described.
5. In a street roller the combination of a roller, a frame, a draft tongue adapted
to be swung around to either side of said roller and a device for holding the
frame from oscillating on the roller while the tongue is being swung around; said
device consisting of a shoe and a screw for moving the shoe, substantially as shown 5
and described.
6. In a street roller, the combination of a frame a roll journalled in the frame
an arch secured to the frame, and a brake consisting of an eccentric secured to
said arch, a rod for moving the eccentric into contact with the roll, and a link for

page_text: holding the eccentric out of contact with the roll; substantially as and for the
purpose set forth.
