JOHN NEWLOVE, OF MICHIGAN CITY, NDIANA,

STREET-SWEEPER.

SPECIFICATION forming part of Letters Patent No. 469,030, dated February 16, 1892.

Application filed .Tuly 11, 1891.

To call whom it may concern:

Be it known that I, JOHN NEWLOVE, a citizen of the United States, residing at Michigan City, in the county of La Porte and State of Indiana, have invented certain new and useful Improvements in Street-Sweepers; and I do hereby declare that the following is a full, clear and exact description of the same, reference being had to the anneXed drawings, making a part of this specification, and to the letters of reference marked thereon.

This invention relates to certain new and useful improvements in street-sweeping machines, and is designedmore especially as an improvement upon the construction shown in my patent, No. 433 538, dated August 5,1890.

I have reversed the machine, applying the draft at the end farthest from the brush and delivering the dirt into a receptacle at the forward end, so as to throw the weight nearer the front.

I provide improved means for elevating the brush from the ground and 'for actuating an apron which I arrange between the brush and elevator. I arrange to elevate both the brush and apron sinultaneously by simple means. This apron or dustpan is arranged so that its lower edge drags on the ground, while its upper edge vibrates on a rod.

I provide an improved brush, which may or may not be provided with steel fingers, the brushes being carried by springhooks or rings, which permit the brushes to readily adapt' themselves to any inequalities in the ground or pavement over which the machine is traveling.

Other objects and advantages of the invention will hereinafter appear, and the novel features thereof will be specifically defined by the appended claims. v

The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon,form a part of this specification, and in which-` Figure 1 is a side elevation of my improved machine with a portion broken away. Fig. 2 is a vertical longitudinal section through the same. Fig. 2 is a vertical section on the line .e z of Fig. 2. Fig. 3 is a side elevation from the reverse side to Fig. l. Figat is a top plan seen' from Fg. 2;

with portiors broken away. Fig. 5 is a detail of a portion of the brush-cylinder.

Like letters of reference indicate like parts throughout the several views.

Referring now to the details of the drawings by lette-,A design-ates the main body or case of the machine, which is provided with two hinged covers A' and A'asuitable crosspiece a being provided to form a support for the adjacent edges of the two doors, as seen in Fig. 2. To theforward end of themain body or case there is attached in any suitable manner a cross-piece a in which is swiveled the vertical pin a which earries at its lower end the front guide-whe`el A and to the upper end of which is attached the tongue or pole A as seen best in Figs. l and 2. The cross-piece a' is secured to the body at a slight distance above the lower edge thereot', and the lower front edge of the case or body is cut away, as shown at a, as seen in Fig. 2, to provide for the setting ,of the guide-wheel close to the case and provide room for the guide-wheel to work, as seen in Figs. 1 and. 2, by which means a square 'corner may be turned, if desired. The cross-piece a' may be braced byinclined braces a asshown in Figs.

l and 2, if desired. i

B is the dirt-receptacle. It is arranged at the forward end of the cas'ewithin the latter, and its bottom' inclnes in opposite directions from a lon-gitudinal center toward each side, as seen best in Fig. 4:, being provided at each side with a hinged door B', one of which is shown up in Fig. 1. Any suitable means may beprovided for holding the doors open, if desired. v

C is an elevator eonsisting of an endless band or belt carried over: the drums or rollers c and being provided upon its outer surface with cross-slats c', as shown best in Fig. 2. This elevator is' arranged in an inclined position, as seen in Fig. 2, and is designed to re: ceive the dirt fro m the apron or dust-pan upon which it is brushed by the brushes, as will be The pintles of the rollers c are journaled in elongated Slots '0 in the walls of the case, as seen in Fg. 1, and are adapted to be adjusted, when necessary, by the arms O', which are screw-threaded at one IOO 4 ri-al, to the outer faces ofwhi-ch areatt'ached i end and passed through eyebolts 0 on the sides of the case and provided with nuts 0 for adjusting them, the arms being connected with the pintles of the rollers in a manner similar to the eorresponding Construction in my prior patent and Operating in the same way.

Dis the main aXle, carrying the main wheels D' and` suitably journaled in the walls of the E' is a pulley on the s-hafit of the uzpper roller of the-eleVa-tor, and E is an idler* on a stub-shaft upon the: same' side of the case and in proxin ity thereto, as seen best in Fig. E is ar pu l l'ey'on the'shaft of the bru'sh-cylind -er, and over this p-ulley, over the pulley' (1 u n-der the: idler' E over the idler E and under the pu 'lley E' passes the cndless belt F, asshown in Figs. 3 and 4, so that motion isi-nparted to the brush-shaft and` to the elevater.

Gr is the brush-shaft. It is su itably journaled in vertically-adjustable bearings g, as seen bes-t in Fig. 1, and on this shat't' are the heads G", which are provided with radial groovesg', as seen best inFigs. 2 and 5', in which arearranged the rods g?, as see-n best inFig 5, and around which are the-springs 9 H are rings of some suitable springy mate-` in an y suitable man ner the bars G which Carry the brushes g, the' end s of the bars being-"provided with offsets and arranged in` theradial grooves of the heads,as seen in Fig. 5. This Construction provides for the holding of the brushes te their work and yet allows them to-yiel'd when passing? over ob-- structons'. Spring-plates H' for adding` stiffness to' the: brushes may be provided, if d'esired, uponthe bars, as seen` in Fig. 2' and by dotted lines in Fig.. 5, being preferably alternately'arranged, as shown in Fig. 2. When forus'e upon asphalt pavement, these fin-gers are preferably omi'tted. The bars Gr are preferably each fol-med in two parts separated at the center, as seen in Fig. 5, so as to allow one part to yield independent of the other.

I is a cross-bar provided with fingers t' to Work between the brushes to keep them from becoming clogged up.

J isa dust pan or apron arranged between the elevator and brush, with' its upper end carried by a pivot or rod j and its lower end: ar-

` seen best in Fig. l.

ranged to contact with the ground, as seen in Figs. 1 and 2. It is designed to be'elevated from the ground when desired. v

In order to elevate the brush-cylinder and the dust-pan from the ground when desired,I

t provide the mechanisn shown in Figs. 1 and 4, in which K is a chain or rope or cord attached at one end to the dust-pan, as at j', and its other end, after passing over the pulley K', is fast to a drum L, carried by a suitable shaft at the forward end of -the case, as M is another chain, cord, or rope attaehed at one end to the hearing of the brush-shaft 'and at its other end to a pnlley m, as seen in Fg. l. nec'ted to an arni. N', fast' on the shaft of the pulley m, and its. other end attached to` the drum L as; seen in Fig.` l. The drum is provided: with a. ratchet-Wheel 0 and with a lever 'O and pawls 0', as seen` in Fig; l. The shafit of the pulley m extends to the oppositeside of the case` and carri-'es a' like: pu'l l'ey m connected by cord m with. thebear-ingof the brush-shaftupon that side, as seen.- in Fig. 3, s'o that by manipulation of' the lever O the brush and thed usvpan Will be siinultaneously raised When d'esi red.

Modificatio'ns in detail may be res'o-'ted to without (leparting frorn the: spirit of the in vention or' sacrificing any ot'` its. advantages.

What I claim as new i s- 1. In a cylindricalbrus l, the combination, with the heads having rad i al grooves, ot' the shaft, the, spring-held bars G paral lel with the-s-haft,t'he s-pring-bandsdiseonnected from the shaft and carrying said bars, and. the brushes carried by' said bars, as setfo'th,

2. In a cylind-rical brush thecombination, with the heads having, 'ad ial grco-ves, of' the' shaft, the spring-held bars G. parall'el' with the shaft, the spring-bands d-iscon'nected from the shaft and carrying said bars, the. brushes carried bythe bars, and. the spring-plates on the bars parallel with the brushes, substantially as 'and for thepurpose specified The combination, with the heads' having radial grooves, the shaft, the rods arran'ged in the grooves, the springs around said rod's',.the bars parallel with the shat't'and having oltsets at' theends and sleeved on the said: rods the spring-bands, and the brushes carried by said bars, all substantially as shown and d'escribed.
