STREET-SWEEPER.

SPECIFICATION forming part of Letters Patent No. 655,971, dated August 14, 1900.

Application filed March 7, 1900. Serial No. 7,622. (No model.)

To r'tZZ whom, it mag concern: r

Be it known that I, CORNELIUS O. GARDNER, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Street-Sweepers, of which the following is a full and complete specification, such as will enable those skilled in the art to which it appertains to make and use the same. g

This invention relates to street-sweepers and the object thereof is to provide an apparatus of. this class whereby the refuse and dirt may be removed from streets and'roads thoroughly and quickly and may, if desired, be put up into separate bags or other receptacles for transportation to a refuse-dump.

The invention consists in the construction and arrangement of parts hereinafter specified.

In the accompanying drawings, forming part of this specification, in which like refer ence characters denote corresponding parts in the several views, Figure 1 is a side elevation of a street-sweeper constructed according to myinvention; Fig. 2, a plan view thereof 5 Fig. 3, a transverse section of a portion thereof upon the line 3 3 of Fig. 2, and Fig. 4 a transverse section thereof upon the line 44 of Fig, '2. V

In the practice of my invention I provide amain frame comprising forwardly-converging side members 5 and 6, a transverse rear member 7, and a forward transverse member 8, beneath which is arranged the steeringtruck 9 of any suitable form and provided with'the forward wheels 10, and upon which frame member Sis supported a seat 11 of any suitable form. A drive-shaft 12 is journaled in the frame members 5 and 6 adjacent the rear transverse member 7 and is provided with drive-wheels13, which also operate'as the rear supporting-wheels of the sweeper. Connected with the rear ends of the side frame members 5Vand 6 is a depending step 14. Secured to the side frame members 5 and 6am a pair of-brackets-15 and 16, respectively, in which are slidably mounted a pair of guide-arms 17 and 18, respectively, by which is supported an angular casing 19, which is closed, except upon the bottom, and

is provided at one side with an angular extension 20.

Supported and j ournaled in brackets21, arranged upon either of the side frame members 5 and 6, is a supporting-shaft 22, provided centrally with a gear 23, and connected with said shaft 22, at either end thereoffare a pair of supporting-chains 24, which support and carry the casing 19 and extension 20 thereof and are adapted to be wound upon the shaft 22 or unwound therefrom to raise or lower the casing 19 and extension 20 thereof, which latter are guided in their elevation and lowering by the guide-arms 17 and 18, which, as above described, operate in the brackets 15 and 16, respectively.

The side frame members 5 and 6 are connected approximately centrally by a transverse brace 25, and journaled in brackets 26, connected one with said brace 25 and one with the rear transverse frame member 7, is an adjusting-shaft 27, provided with a wormgear 28, which operates in connection with the gear 23 to raise and lower the casing 19 and extension 20 thereof. The adjustingshaft 27 is provided at its rearmost end with a hand-wheel 29, whereby an operator standin g upon the step 14 may readily adjust the casing 19 and extension .20 thereof.

Journaled in the casing 19, at the ends thereof and in the rearmost portion thereof,

revolving sweeper-brush 31 of the usual or any preferred form, and the brush-shaft 30 is provided at one end with a sprocket-wheel 32.

A main carrier-casing 33, open at but one side and end, as shown clearly in Fig. 4, and preferably rectangular in form, is pivotally mounted in the casing 19 forward of the brush-shaft 30, the pivotal connection of said casing 33 being at the forward lowermost edge thereof, as at 34.

Four shafts, 35, 36, 37, and 38, respectively, are journaled in the casing 33 longitudinally thereof, and at the corners thereof and mounted upon the same is a continuous car- \rier composed of flexible side members 39 and transverse spaced strips 40, said side memsaid main carrier, composed of the side mem- I I I y bers 39 and transverse strips 40, is continuous in formation and arranged to be moved within the casing 33 transversely of the sweeper. The casing 33 is beveled and open at one end, whereby it projects into the extension 20 of the casing 19, and journaled in said extension 20 is a shaft 42, which projects from the side of the said extension and is provided upon its outer end with a sprocket-wheel 43. A closed supplemental carrier-casing 44 is arranged longitudinally of the sweeper at one side thereof and ranges upwardly from the casing extension 20, being provided at its outermost end with a discharge-spout 45. The forward end of said supplemental carrier-casin g 44 projects within the extension 20 of the casing 19, as shown at 46, and is open at the top within the said extension, and one side thereof is curved inwardly and downwardly, as shown at 47. A shaft 48 is journaled in the spout 45 of the supplemental carrier-casing 44, and the shaft 48 and shaft 42 are provided with pulleys 41. Mounted upon the pulleys 41 within the supplemental carrier-casing 44 is a supplemental carrier comprising side members 39 and cross-strips 40, identical in form and construction with the corresponding parts of the main carrier mounted in the main carriercasing 33.

The main carrier and the supplemental carrier each follow in the lowermost phases of their movements the contour of the lowermost portions of the casings in which they operate, passing closely adjacent thereto, whereby dirt and refuse introduced into either of said casings will be moved by the respective carrier in a direction predetermined by the direction of movement of the carrier, as hereinafter described.

Journaled in the casing extension 20 in alinement with the shaft 35 of the main carrier-casing is a stub-shaft 49,upon which is a gear 50, and the shaft 49 is connected with one end of the shaft 35 by a knuckle-joint 51, whereby the carrier-casing 33 may be oscillated without disconnecting the shafts 49 and 35. The gear 50 is provided with a square bore, and the shaft 49 is also square,whereby the gear 50 may slide upon the shaft 49 to accommodate oscillation of the casing 33, and the gear 50 is prevented from detachment from the shaft 49 by a bracket 52, secured to the casing extension 20 and inclosing the said gear 50.

A short shaft 53 is journaled in brackets 54, secured to the top of the casing extension 20, and is provided with a gear 55,which meshes with the gear 50 upon the shaft 49. The rearward end of the shaft 53 is provided with a beveled gear 56. Mounted transversely of the extension 20 of the casing 19 is a shaft 57, journaled in brackets 58 and provided at its outer end with a sprocket-wheel 59, which is geared in connection with the sprocket-wheel 43 upon the shaft 42 in the supplemental carrier-casin g 44 by means of a crossed sprocketchain 60, as shown in Fig. 1. The inner end of the shaft 57 is also providedwith a sprocketwheel 61.

A transmission-shaft 62 is journaled transversely of the sweeper-frame in the side mem-.

bers 5 and 6 thereof and is provided at one end with a gear 63,which meshes with a gear 64 upon the supporting drive-shaft 12. The shaft 62 is also provided with two sprockets 65 and 66, respectively, of which the sprocket 65 is geared,in connection with the sprocket 32,upon the rotary brush-shaft 30 by means of a chain 67, and the sprocket 66 is geared,- in connection with the sprocket 61,upou the shaft 57 by means of a chain 68. Upon the rotation of the shaft 62 by means of its gearing, in connection with the supporting drivewheel 12, as above described, it is manifest that the rotary brush-shaft 30, together with the brush 31, will be rotated by means of the sprocket-chain 67, the supplemental carrier, mounted in the casing 44, will be moved by means of the sprocket-chain 68, shaft 57, sprocket-chain 60, and shaft 42 in the supplemental carrier-casing, and the main carrier within the main carrier-casing 33 will be moved by means ofthe sprocket-chain 68, shaft 57, shaft 53, shaft 49, and shaft 35 within the main carrier-casing 33.

The construction and arrangement of parts are such that upon the forward movement of the street-sweeper the rotary brush 31, the periphery of which projects beneath the casing 19, will be rotated in adirection to cause the refuse, earth,and other obstacles engaged thereby to be swept within the main carriercasing 33 and deposited upon the main carrier therein. Furthermore, the main carrier will be moved in such manner that the bottom portion thereof will move the substances deposited within the carrier-casing 33 transversely of the sweeper along the bottom of said casing 33 and up the side of that portion of the supplemental carrier-casing 44 which projects within the extension 20 of the casing 19, as shown in full lines in Fig. 3 and in dotted lines in Fig. l, finally depositing said substances in the forward end of the supplemental carrier-casing.

The side of the forward end of the supplemental carrier-casing is, as above described, curved at 47, whereby the substances dropped by the main carrier in its upward movement from the shaft 36 to the shaft 35 will be guided into the supplemental carrier-casing, and this depositing of the said substances by the main carrier into the supplemental carrier-casing is caused by the formation of the adjacent end of the main carrier-casing 33, which, as above described, is beveled, the sides thereof ranging convergently upwardly, as clearly shown in Fig. 3. Further, the supplemental carrier is continuously moved in such direction that the substances deposited by the main carrier in the supplemental carrier-casing are moved along the bottom of the supplemental carrier-casin g and finally discharged saeri e from the spout 45 thereof into any suitable receptacle or receptacles, such as bags, in which the refuse and dirt or other substances may be removed to the dumps.

Fixed to the forward portion of the main carrier-casing 33 are a plurality of segmental arms 69,-which project through openings in the forward portion of the casing extension 20, and mounted upon the segmental arms 69 exterior of said casing extension is a coiled spring 70, which operates between the casing extension and a thumb-nut 71, which is turnably mounted upon the forward end of the arms 69. By means of the arms 69 and thumbnut 71 the oscillatory position of the main carrier-casing 33 may be regulated with reference to the character of the road-bed over which the street-sweeper is passing to avoid collision thereof with stones and other obstructions.

By means of the adjusting-shaft 27 an operator at the rear of the street-sweeper may regulate the vertical position of the casing 19 and extension 20 thereof, and such position may be maintained by means .of a pawl 72, pivoted to the transverse frame member7 and operating in connection with a ratchet 7 3,fixed to the hand-wheel 29. The object of such regulation and variation of the vertical position of the casing 19 and extension. 20 thereof is to cause a suitable engagement of the brush 31 with the street or road surface to thoroughly cleanse the same of refuse and dirt lying thereon or clinging thereto and project the same into the maincarrier-casing 33, whence it is carried into the supplemental carrier-casing 4A: and discharged through the spout 45 at the rearward end thereof.

I do not limit myselfto the specific con-- struction and arrangement of parts herein described, but reserve the right to vary the same within the scope of my invention.

Having fully described my invention, I claim as new and desire to secure by Letters Patent 1. A street-sweeper, embodying a frame, a main casing mounted therein a carrier-casing pivotally supported in said main casing and provided with a main carrier arranged transversely of the apparatus, said carrier-casing being provided with means for adjusting the same, and a supplemental carrier which is arranged longitudinally of the apparatus and operates in connection with said main carrier, a brush whereby the sweepings are directed upon said main carrier, means for operating said carriers, and means for operating said brush, substantially as shown and described.
