BROOM SWEEPER Filed Nov. 4, 1957 2 Sheets-Sheet 2 ATTOXR` NEY Patented Jan. 31, 1939 UNITED STATES PATENT oFFicE i al4a-irs A The present invention relates to new and useful improvements in broom sweepers, and it has for its object to provide an automatically adjustable f broom sweeper, which may be manipulated with 5 great ease, andl applied and turned in different directions in order to sweep places' and corners to which no access can normally be had with the sweepers now in use.
j Furthermore; the construction ofmy said device is to the eilect that the broom proper will always retain its full sweeping capacity, even if the bristles of the broom become worn and shortened, as the special construction of my device takes this feature into consideration, as will hereinafter appear.
As the construction of my device is 4.compara-- tively simple, the cost of. manufacturing should be proportionately low.
yWith the above and other'objects in view, this inventioneconsists of the -novel features of construction, combination, and arrangement of parts, hereinafter fully described, claimed and illustrated in the accompanying drawings forming part of this application, and in which similar characters of reference indicate corresponding parts in all views, and in which:
Figure 1 is a perspective view of an automatically adjustable broom sweeper.
Figure 2 is an exploded view of the invention, as shown in Figure l, and illustrating the major parts ofl my device. y Figure 3 is a side elevational view, showing the inside of one of the large wheels, with the brush member broken oil', and showing also the brush proper provided with new bristles, indicating at the same time the driving gear and the relative position of the latter to the'axle drive, said relative position depending upon the length of the bristles. 40 Figure 4 is a front elevational view of the inner side of one of the larger, or front wheels, showing the bristles of a brush member worn down, and thereby affecting the relative position of the drive gear with'respect tothe drive shaft,
and showing also one of the frames for holding` the driving member. v
Figure 5 is a front elevational view, showing the inner part of a front wheel, i. e., one of the larger wheels, ready for assembling.
Figure -6 is an elevational view, showing thel y driving shaft with gears attached thereto.
Figure 7 is a front elevational view, showing the brush gear.

Figure 10 is a transverse sectional view of the bottom part of the axle, shown in Figure 6.
l Figure 11 is an elevational view of the drive 5 shaft, as seen also in Figure 6, indicating more clearly the' recess for guiding the up and down movement of the drive gear, shown in the Figures 8 and 9. y
' Figure 12 is a topview of an enclosing member l0 for securing the brush to `the brush shaft.
. Fiure 13 is a transverse side elevational view of the member shownin Figure 12.
Figure 14 is a front elevational view showing the parts illustrated in the' Figures 8, l0 and 12 l5 assembled, and attached to the brush member.
Referring more particularly to the drawings,
2li indicates a frame, or carriage, adapted to ref bars 2l, and the steering bar 28, which latter is' integral with the carriage frame 2li, and thus 1capable of moving the carriage in any direction.
To facilitate the operation, the said steering bar may be secured in adjusted position by means 35 of a bolt I0 through any of the openings 8i in the cross-bar l2.
I'he carriageframehassecuredtoitthesmall wheelsA 8l, as shown.
vz'lhe brush sweeper proper comprises an axle 40 84 with bristles 85 secured to the latter, as shown in Figure 2. Said bristles 85 are shown as new in Figure 8, and in a partly worn down condition in Figure 4, as indicated bythe numeral 25'."
vWithin the carriage are mounted two large 45 wheels Frames yI'l are secured to the carriage 20, and connected to each other by a cross bar Il; said frames. are adapted to support the gear arrangement hereinafter described. 4
Each one of the large wheels 88 has upon its inner side securely attached thereto a gear I8, as shown especially in the Figures 4 and 5.
A short center axle I8 is inserted through each of the wheels 88, as shown especially in Figure 3; ss
each axle 39 supports a frame member 40 and.
one of the depending side members of the carrlage 20, as shown in the Figures 3 and 5.
In each oi' the frame members 31 is, as shown 'in Figure 6, pivotally mounted a vertical axle 42.
said movement by a yprojection 45 formedupon said gear 44; said projection being adapted to slide in a guiding recess 46 formed inthegxertical axle 42. The gear 44 is upon its depending part@ 41 and upon the outer surface thereof formed with an annular groove 48, as shown in Figure 8. Upon the axle 42 is further pivotaliy mounted la block member 49, as shown in Figure 6, and
more especially in Figure 10; saidblock member is in its upper part formed with a bore 50, which is adapted to receive therein the depending part 41 ofthe gear 44; said block member has mounted in the sides thereof screws 5I, which are :adapted to loosely engage the recess 48 in the depending portion 41. The block member 49 has a projecting axle 52 adapted to receive a gear member 53 thereon, said gear member being shown separately in Figure 7, and attached in Figure 3; this gear 53 yis adapted `to mesh with the gear 44, and turns upon the axle 52,. the gear being held upon said axle by means of a nut 54. To the gear member .53 is securely attached a casing 55, which is shown separately in the Figures 12 and 13, and attached in the Figures 3 and 14. 'I'he casings are attached to'each end of the brush axle, by means of screws 56, and to the gear 53, as yshown in Figure 14.
The frames 31 are securely attached to the frame members of the carriage 20 by rivets 59, as shown in Figure 3, and to the frame 40, as shown in Figure 3, also.
The axle 42 is turnably mounted in the frames by means of the screws 60 and 60'.
,l It will be apparent that the gear 44 and the block member 49, which, as described, are conamupas nected to the brush, will assume a position upon the axle 42, depending upon the height of the spirit of the inventiton,`\and I do not' therefore' wish\to limit myself to the\exact construction and arrangement shown and described herein. What'I claim as new, and desire to' secure by ,Letters Patent of\ thecUnited States, is:
-In a device of the class described, a carriage structure having two side members, a large wheel arranged inside of each of the latter, and a short axle securing the side members to said wheels, respectively, a` gear iixedly arranged upon the inner side of each of said wheels, frames disposed within the side members and a cross bar connecting said frames together, a vertical axle being formed with a vertical recess therein and pivotally mounted in each of said frames, a gear xedly attached to said vertical axle and adapted to mesh with the gear upon the inner side of said wheel, a lower gear mounted upon said vertical axle and adapted to slide upon the latter, said lower gear having a projection thereon adapted to slide in the vertical recess of the axle, the lower gear being made with a tubular depending portion formed with an annular recess therein, a block member slideably mounted on the axle beneath said lower gear, said block member being formed with a bore adapted to receive therein the depending portion of said lower gear, a stud mounted in the side of the block member and made -to loosely engage said annular recess, a short horizontal axle integral with the bloei: member, a gear mounted upon said latter axle and adapted to mesh with the aforesaid lower AUGUST SANDBEBLG.
