SPECIFICATION forming part of Letters Patent No. 625,163, dated May 16, 1899.
Application tiled February 1,1899. Serial No. 704,093. (No model.) l
To all whom, it may con/087%:
Beit known that LPIRRE HAnRsrrga citizen of the United States, residing at Chicago, lin the county of Cook and State of Illinois, have invented certain new and useful Improvements in Street-Cleanin g Machines for Boulevards, Parks, and Paved Streets,` of which the following, when taken in connection with the drawings accompanying and forming a part of this specification, is a description sufficient to enable those skilled in the art to which it pertains to understand, make, and use the same.
This invention relates to that class of cleaners designed to gather or pick up articles, either dirt or other material, from the ground `and deposit the same in a receptacle provided therefor.
The object of this invention is to obtain a' machine which shall be particularly arranged for and fittedV to maintain park-boulevards and asphalt-paved streets in a cleanly and presentable condition; and for the purpose of carrying out the above-named object I have obtained a machine whereby dirt can be picked from the ground,either street or boulevard, and deposited ina receptacle therefor carried by and forming an element in the machine. I have also obtained a machine from which the receptacle used can be readily taken and another and like receptacle substituted therefor. I have further obtained a machine in which the several adjustments necessary to retain the parts in proper relative position as the machine is used and such parts are worn are simple, easily made, and not liable to get out of order.
In the drawings referred to and wherein a letter of reference applied to designate a given part is used to designate such part throughout'the several figures wherever it appears, Figure 1 is an end elevation of a cleaningmachine embodying the invention; Fig. 2, a vertical sectional view adjacent to the driving-wheel of the machine, showing the apron and shovel and adjustable shoe of the machine in proper relative position; Fig..3, a
side elevation of the upper end of the frame of the apron and of a U-shaped frame to which the apron-frame is attached and to which U-shaped frame also the axles of the machine are secured; Fig. 4, an end elevation of the lower end ofthe apron-frame with the' 7 an end elevation of a dirtreceptacle which is removably attached to the machine.
A, Fig. l, is the non-rotatable axle ofthe machine, on which the wheel a isrotatably mounted'in the ordinary way. Axle A (one on each side of the machine) is secured to Y the upper end of the U-shaped frame B.
b, Fig. 2, is the horizontal member of U- shaped frame B, andb a vertical member thereof.
h2isa slot in vertical member b of U -shaped frame B, and b3 is a hole therein through which the axle A extends and is attached thereto.
C is a dirt-receptacle having the projection or lug C on each end thereof, respectively.
C2 is an arm rigidly secured at one end thereof to vertical' member b of U-shaped frame B.
C3 is a recess in the outer end of arm 02,1'n which recess the projection or lugC' of the receptacle C rests when such receptacle is mounted on the machine. The forward part of the receptacle rests on horizontal member h ofthe U-shaped frame B. The receptacle C will therefore maintain its position by gravity on such arms C2 C2 (one on each side of the machine) and member b of U -shaped frame B.
C5 is the handle by which the machine is propelled.
D is the apron-frame of the machine.
d is a bolt extending through the apronframe D, near the upper end thereof, andthroughV the slot h2 in vertical member b of U-shaped frame B.
f d', Fig. 2, is the apron of the machine.
Apron d is secured to the apron-frame D, the upper end of the apron extending to above the receptacle C when such v'receptacle is placed on the machine, as above described and asfillustrated in Fig. 1.
d2 is the'lower end of apron d', formed t0 receive on the upper face thereof the upper edge of the adjustable shovel N, hereinafter described. (See Figs. 2 and 4.)
E is a side bar (there being one thereof on each side of the machine) adj ustably seeurin g lthe apron-frame D to the upright member b' of U-shaped frame B. The adjustment secured bythe side bars E E is to obtain proper tension on the brush-chain J, hereinafter described.v The adjustment of the upper end of the apron-frame D, which is obtained by bolt d extending therethrough and through the slot h2 in vertical members b b', is to obtain proper relative position between the apron d and the brushes L, hereinafter described, at the Lipper end of such apron.
e is a bolt extending through the side bar E and apron-frame D, and e' is a bolt extending through slot e2 in side bar E and through vertical member b of the U-shaped frame B.
F is a wheel secured to one of the wheels a a of the machine to rotate with such wheel and having internal gear-teeth thereon.
G is a wheel secured on shaft g to rotate therewith, having external gear-teeth engaging with the gear-teeth in wheel F.
g', at the upper end of vertical member b',
forms the bearing in which shaft g is rotatably mounted. (See Figs. 2 and 3.)
H H are sprocket-chain wheels rigidly secured, respectively, to shaft g on each side of the machine to rotate therewith.
H', Fig. 2, is an ordinary clutch, by means of which the wheel G is thrown into and out of engagement with the wheel F, so as to rotate or not, as preferred, the sprocket-chain wheels H, there being two sprocket-wheels H, one adjacent to each of the upright members h b of U-shaped frame B.
I I are sprocket-chain wheels rigidly secured to shaft t' to rotate therewith. Shaft t is rotatably mounted in ihe frame D, near the lower end thereof, as illustrated in Figs. 1, 2, and 4,
J J are brush -chains extending, respectively, over sprocket-wheels H H I I and having secured thereon at intervals the brush sockets or frames K K.
L L are the brushes, by means of which the material gathered on shovel N is elevated on apron CZ and delivered therefrom into the receptacle C in the operation of the machine.
Brush sockets or frames K K, respectively, comprise bed 7c, sides 7c 7c', and turned-in edges 162702. The brushes L are inserted in the brush sockets orframes K by being forced thereinto or slid, so that when a given brush becomes worn it may be removed and a new one substituted therefor.
M, Fig. 2, is a roller mounted on shaft m in adjustable frame M to come in contact with the chain J, adjacent to the lower end of the apron d', to adjust the brushes to the apron at such lower end of the apron. v'
m is a bolt extending through slot m2 of the frame M' and through apron-frame D.
By means of the adjustment last above described of the rollers M M with reference to the lower end of the apron-frame, such rollers forcing the chain to an adj usted position and the adjustment of the apron-frame D toward the brushes at the upper end of such frame by means of bolt d in slot b2, hereinbefore described, any desired adjustment of the entire apron d with reference to the br'ushes passing over it is obtained.
N is a shovel adj ustably secured to the apron-frame B, at the lower end of such apronframe, by means of bolt n, passing through slot n'.
n2 is a loop or pocket on theunder side of the shovel N, into which loop or pocket the forward end of the shoe O extends, such forward end of the shoe being lettered O3. Slice 0 is adjustably secured in place by bolt O', extending through slot O2 in such shoe and through the apron-f rame D, such bolt having a nut thereon.
The shoe O is not used by me when the machine is employed for gathering refuse, litter, or dirt on an asphalt -paved boulevard or street, its purpose being when used to prevent the forward edge of the shovel N penetrating a street or boulevard,when the surface thereof is soft or dusty, beyond a determined distance. To show the attachment of the forward end O3 of shoe O to the shovel N, such shovel N is shown in Figs. 1, 2, and 4 at a.
greater incline than I prefer to place such shovel ordinarily. Any adjustment of the ineline of the shovel N is readily obtained by loosening the nut on boltn in slot n'. (Well shown in Fig. 4L.)
This machine is particularly adapted for use on park-boulevards in place of the ordinary sheet-iron scoops now employed for that purpose and is designed to be pushed by a man or boy by handle C5 about the street. The receptacle C is made removable, so that when the same is filled it can be lifted from the machine and placed to one side of the boulevard and a duplicate receptacle substituted therefor on the machine or to be removed from the machine at any time and the contents thereof emptied into a cart or other receptacle.
By obtaining the several adj ust-ments hereinbefore particularly described I am able to make a machine which will well perform the work it is intended to do and so easy to manipulate and propel that a man or boy may readily move or push it about a street or boulevard and maintain the same in an aceeptably clean condition even when many horses are driven thereover.
