PAVEMLNT 0R SIDEWALK SGRAPER.
Sterns CHARLES F. BIERBAOH AND GEORGE E. BIERBAOH, OF MILWAUKEE,
' WISCONSIN.
PAVEMENT` OR SIDEWALK SCRAPER.
SPECIFICATION forming part of Letters Patent No. 543,920, dated August 6, 1895. Application nea November 3,1894. serial No. 528,258. (No nicher.)
To all whom it may concern.:
Be it known that we, CHARLES F. BIERBACH and GEORGE E. BIERBACH, citizens of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented new and useful Improvements in Pavement or Sidewalk Scrapers, of which the following is a specification.
Our invention relates to improvements in street and sidewalk Scrapers, and pertains especially to han d-actuated devices for cleaning asphalt pavements, cement walks, and similar smooth surfaces.
The object of our invention is, rst, to lessen the labor of operating the scraper by means of wheels so located that a balance can easily be'secured thereon; second, to combine with 'a scraper a rotary brush for sweeping light substances upon the scraper while the latter is bein g forced beneath them; third, to provide for the operation of the scraper independently of the brush Without removing the'latter.
In the drawings, Figure I is a side view of our invention with dotted lines showing the position of the brush when not in use. II is a rear view showing the position of the wheels with reference to the body of the scraper. Fig. III is a detail vshowing the spring-clip for engaging the hoisting-lever of the brush. Fig. IV is a detail showing'the sprocket-wheel with coupling-lever. Fig. V is a detail of the coupling mechanism; Fig. VI is a detail of the rear portion of the scraper, showing a pocket adapted to receive utensils, as hereinafter described. Fig. VII is a detail view of the hoisting-lever.
Like parts are referred to throughout by the same reference-letters.
A refers tothe scraper-plate, which is preferably formed of sheet'rnctal with sides B and detachable steel wear edge O in front.
D is ahandle by means of which the scraper is pushed ahead of the operator. j
The rear side of our scraper is supported slightly above the surface on wheels E E, and by bearing downen the handle D the entire scraper can be lifted and borne uponA the anced we have provided the wheel-housings FV F, into which the wheels project, thus en- Fig.
abling the axle or shaft to be located in close proximity to the scraper or underneath the latter, if so desired, and at the same time permitting the entire scraper to run closely to the surface of the ground.
The wheels E E are keyed to the shaft G, which extends transversely of the scraper, the projecting ends being provided with sleeves H, to which are attached brush-supporting side bars I I. The front ends of these bars I I project beyond the edge of the scraperl and are connected by the rotating-shaft J, provided with a-cylindrical brush K. The ends of the bars with the shaft and brush are supported at an appropriate distance above the surface by means of the adjusting-screw L, which passes through the flanged plate M and rests upon the supporting-lug N on the side of the scraper.
Motion is communicated from the rotating wheels E E to the brush by means of the shaft G, sprocket-Wheels O and O', chain P, and
shaft J, the sprocket-wheel O being provided with a coupling-lever Q for throwing it into and out of gear with the shaft G.
It is obvious that in scraping wet surfaces the brush should be withdrawn, andA for this purpose we have provided the rod R, connecting the two side bars I I near the rear of the scraper, and a hoisting -lever S, supported loosely by a sleeve S upon the shaft G, and provided with an arm T, similarly attached to the rod R, so that by drawing rearward on the lever S the bars I I are llifted upward with the brush to the position indicated by the dotted lines in Fig. l, and are held in that position by the spring-clip U, attached to the scraperhandle D. The brush mechanism is then thrown out of gear by lifting the couplinglever Q and disengaging the sprocket-wheel O, as shown in Fig. V, leaving the scraper to be operated independently.
If desired, the coupling-gear can be applied to the wheels E E, thus permitting the shaft G tovremain stationary when the sweeper is out of gear, the wheels in such case being, of course, provided with bearings upon the shaft.
We have also formed a box or pocket Won the rear-side of the scraper, in which may be placed various hand-implements adapted to IOO be used for cleaning or adjusting the parts of the scrapersuch as brushes, wrenches, screw-drivers, oil-cans, &c.
It desired, the pivotal supporting-wheels may be attached direct to the bottom plate of the scraper and the side and rear cud walls be dispensed with.
Having thus described our invention, what We claim as new, and desire to secure by Letters Patent, is-
l. A street and side-walk scraper consisting of the combination of the scraper plateA, the Wheel-housings F, F formed in the rear p0rtion thereof, and the pivotal supporting- Wheels adapted to project into said housings, together with the manually operated actuating handle D extending upward and rearwardly from the body of said scraper and adapted to hold the same pivotally upon the Wheels, substantially as described.
2. A street and side-Walk scraper consisting of the combination of the scraper plate A, provided with the detachable wear edge C, sides B, and a raised back having the pocket W, the Wheelhousings formed in the rear portion of the scraper plate and the pivotal supporting wheels adapted to project into said housings, together with the rearward projecting actuating handle D, adapted to hold the scraper pivotally upon said Wheels, substantially as described.
3. A street and side-walk scraper, consisting of the combination ot a scraper body or pan, having its rear portion supported upon wheels, a shaft upon which said wheels are located, projecting beyond the sides of the scraper, brush supporting bars loosely attached to said shaft and adapted to support a cylindrical brush immediately in front of the scraper, a rod connecting the supporting side bars near their rear ends, and a lever attached to said rod and adapted to raise said supporting bars and brush pivotally upon said shaft, together with a spring clip or lock adapted to engage said lever and lock the brush in a raised position, substantially as and for the purpose set forth.
4. In a street and side-walk scraper, the coinbination with the supporting side bars I I, of an adjusting screw L adapted to operate through the flanged plate M and to bear upon the projecting lug N of the scraper pan, substantially as described.
In testimony Whereot` we affix ourI signatures in the presence of two witnesses.
