SCRAPlNG-MACHINE FOR STREETS, 84.0.
SPECIFICATION forming part of Letters Patent No. 539,642, dated May'21, 1895.
Application filed February 14,1895. Serial No. 538,353- (No model.) I
To all whom it may concern.-
Be it known that I, JOSEPH E. PORTER, a citizen of the United States, residing at Ottawa, in the county of La Salle and State of Illinois, have invented certain new and useful Improvements in Dirt-Scraping Machines for Streets and Roadways; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to improvements in street scraping and cleaning machines and the invention consists of certain novel con- 'structions, combinations and arrangements of parts, all of which will be hereinafter particularly set forth and claimed. 7
It also consists of certain other novel constructions, combinations and arrangements of parts, all of which will be hereinafter set forth and claimed.
In the accompanying drawings, forming part of this specification, Figure 1 represents a side elevation of themachine embodying my invention. Fig. 2 represents a top plan view of the same. Fig. 3 represents a central vertical longitudinal section of said machine, and Fig. 4 represents an end elevation of the same.
A, in the drawings, represents the frame; B, the wheeled carriage upon which it is mounted; O, the endless conveyer or apron; D, the scraper, and E the reciprocating shovels or scoops.
The frame A is mounted upon the wheeled carriage in an inclined position with a greater portion of its length forward of the axle B of the carriage. To brace the frame against the strain incidental to this unequal distribution of the weight of the same upon the two sides of the axle, I provide said frame with transverse brace bars a, vertical brace bars a, and longitudinal brace bars a said brace bars forming as a whole an auxiliary bracing and supporting frame which distributes the strain evenly upon both sides of the axle. As an additional means of support for the forward overhanging end of the frame A, I provide a wheel K which has its swivel pin mounted loosely in journal boxes 10', k attached to two of the cross bars a, a, so as to be capable of a swivel action.
Apron supporting rollers c, c are journaled position.
'upon'said rollers, and is provided upon its outer surface with lateralspaced bars 0 which prevent the dirt thrown upon said apron from sliding down its inclined surface, as it revolves; said bars also taking hold of the accumulated dirt in front of the scraper. The lower ends of the side bars are each provided .upon their upper edges with vertical extensions a which prevent the dirt thrown by the shovels E from passing over the tops of said side bars and thus escaping from the machine.
The scraper D is movably mounted at the lower end of the side bars so as to normally rest upon the ground, by means of supporting bars at which are attached to each end of said scraper and are pivoted, on their respective sides of the machine, to one of the vertical brace bars a. The scraper is made up of three members, or strips; the two outer ones d d being of metal and the third member d which is between said outer members, being of rubber or some such flexible material. All
vof the members are slotted laterally and verd by means of which the said three members are secured rigidly together in any adjusted By this construction of the scraper I am enabled to bring either a stiff metal edge or a flexible edge in contact with the ground,
by simply loosening the bolts d and raising or lowering the flexible strip until it either projects below or is withdrawn above the lower edges of the metal strips. This construction is necessary for the varying conditions of the ground to be scraped. If the ground is dry the metal scraper will be Sllfficient to collect the dirt, but if the street is covered with mud and water a more water tight contact between the scraper and the ground is necessary, and this I provide for in the adjustable, flexible, intermediate portion of the scraper. 1
A hand operated frame a has its ends pivotally mounted on two of the vertical brace rods a and is connected to the scraper D on each side by means of connecting rods 01.
It will be seen from the foregoing that when the frame a is raised by the attendant, the scraper D will also be raised and thus cease to operate to scrape up the dirt, as is necessary when the machine is being taken to and from the point of operation. Suitable latching means such a chain and hook are provided for holding the frame a in its elevated position.
A frame a is attached to frame A and extends upward diagonally, resting against the brace bars of the auxiliary frame, and is provided at its upper end with a transverse guide bar a provided with vertical guiding passages a The shovels E are preferably made of flat sheet metal slightly curved vertically so as to form a scoop shaped blade and are each mounted on atvertical rod or bar 2; said bars being adapted to work vertically'in the guiding passages a as the shovels are reciprocated. This reciprocation of the shovel is caused by a crank shaft f, the crank bends of which are connected to the bars 6 by journal boxes f attached to said bars and through which said crank bends pass. The crank shaft is journaled in side bars 9 attached to frame A and each end of said crank shaft is provided with a sprocket wheel f One of said sprocket wheels f 2 is connected to the sprocket wheel 0 on its respective side of the machine by a crossed sprocket chain h; said chain, because of its length, being supported and guided near its middle portion by a grooved sheave h which is jou rnaled on a pin attached to one of the brace bars of the auxiliary frame.
One of the wheels B of the carriage B is provided with an annular rack b whose cogs are arranged upon its inner face. A shaft H is journaled in frame A and is provided at one end with a gear wheel h which meshes with the rack b and thus said shaft H is re volved as the wheel B revolves. The oppo site end of the said shaft H is provided with a sprocket wheel h which is connected to the sprocket wheel a on that side of the machine by a sprocket chain h; clutch mechanism 77. being arranged between the said sprocket Wheel 0 and the shaft 0 upon which it is mounted. It will thus be seen that when the shaft H is revolved, the shaft 0 is also revolved, if the clutch 72, is set to operate, and thus the apron will be revolved and the crank shaft operated to reciprocate the shovels.
The peripheries of the wheels of the can riage are roughened in any suitable mannerso that they will not slip upon the ground when the machine is in operation.
The operation of the machine is as follows: The machine is first attached to any suitable dirt hauling cart or wagon so that the upper end of the endless apron is directly above the body of the wagon. Now when the wagon is moved forward the dirt collects in front of the scraper D until it reaches a sufficient height to be struck by the reciprocating shovels E which are being moved by the crank shaft with a step by step motion being alternately thrust downward and forward and upward and backward, but at no time touching either the ground or the endless conveyer or apron. The shovels throw the dirt up upon the endless c011- veyer or apron as fast as it accumulates in front of the scraper and as the apron is continually moving upward and forward the dirt is carried with it and as the apron turns about the upper roller 0, the dirt falls from it into the receiving cart. In this operation of the machine the attendant walks behind it and manipulates the scraper by means of the frame a so as to keep it down to its work or to lift it over obstructions, and to carry the machine from place to place the scraper is elevated and retained in this position by the beforementioned chain.
