CARPET-SWEEPER.

' Specification of Letters Patent.

Application filed may 20, 1907. Serial No. 374,783.

To all whom 'it may concern.-

Be it known that I, Grouse B. Deacon,

a subject of the King of Great Britain, and a resident of the city of, London, in the county of Middlesex, in the Province of Ontario. Canada, have invented a new and useful Carpet-Sweepen of which the following is a specification.

This invention relates to a mechanically" operated brush or broom for sweeping care pets or floors and collecting the dust and dirt in dust pans.

lhe object of this invention is to provide a carpet sweeper, in which the brush may be readily, easily, instantly or gradually lowered as it becomes worn;' and one in which the brush will'be so supported that the latter will automatically adjust itself to all uneven or rough places on the carpet or floor, {it the same time that it is governed to a certain limited extent by the pressure on the sweeper, and a further object is to support the dust pans, 'so that they will always be close to but clear of thecarpet, and so supported that no matter how heavy the pressure may be on the body of the sweeper, the dust pans Wlll always maintain the same relative distance from the carpet.

up a piece of coal or other similar large or hard substance on the carpet without interfering with the dust or dirt in the dust pans,

which has been previously gathered.

The invention consists of the im roved construction and novel combination 0? parts as will be hereinafter first fully set forth and described and then pointed out in the claims.

Reference is had .to the accompanying drawings forming a part of this app ication, wherein: v i

12 designates pivot pins, see Fig. 9, one of which is fixed on the inner side of each of said cylindrical bosses,

11, which pivot pins 12 are fitted to and adapted to be inserted in the sockets or recesses 7 in the plates (5, at the opposite ends of the case or body 1; to pivotally connect said handle 10 witlr said body 1.

13 designates springs one of which is employed at each end of the machine, and 14 represents screws secured in each end, a, of the body 1, on opposite sides of the angular end, I), of the bail 8, and said springs 13 extend over and by their own resilience bear on the cylindrical boss 11, and are held in place by their ends partly encircling parts of the shanks of the screws 14 which project hecarpet sweeper which maybe formed of any yond the ends, a, of said body l, and said spring 1s shown bearing on the upper sale of the cylindrical bossrll, but it may be arran ed to bear on any other side of said cylin' rlcal boss 11, if preferred.

The purpose of the pins 12 engaging with the handle at any angle to which it may be adjusted when using the sweeper, or to hold the handle in a vertical position when the sweeper isnot in use, and the forming of the sockets or recesses 7 in the plates 6,

slightly elongated, is to permit the pivotl pins 12 to move and work freely therein.

15 deslgnates wheel shafts wlnch extend lengthwise oft-he maclnne, and the ends of said shafts extend through the shaft openings 5 in the ends, a; and mounted to revolve freely on each end of said shafts 15, just beyond said ends, a, of'the body 1 are the traveling or carrying wheels 16; provided with rubber tires 16. "Slight cuts are made in the opposite sides of the shafts 15 near each of the ends thereof, thus forming a flattened poition 0 adjacent each shaft end.

18 designates thin flat disks which are about twice the diameterof the wheel shaft openings 5, and two of said disks 18 are mounted centrally on each of the wheel shafts 15 in the case or body 1, and said disks 18 are arranged on said shafts 15 opposite each of the'whcel shaft openings 5 in the ends a; and19 are wire sprlngs one end of each of which is secured to the inner face of the ends, a, and their other free ends are adapted to engage with and hold said disks 18, against the inner faces of 'theends, a, to,

prevent. the escape of dust or dirt through said wheel shaft openings 5.

20 designates a fiat'spring, mounted at each end of the body 1, on part of the proectmg portions of the shanks of the screws 14 and 21, secured in the ends, a, of the body 1, and connected .to each end of each of said fiat springs 20, is a couplinglink 22, and in and near the lower end of each of the latter is formed round openings, (1; and extending fron'i'the round openings in opposite directions are elongated openings, 0, narrower than the round opening at. One of each of.

said couplin s 22 is engaged with one of the ends of each of the wheel shafts 15, and when engaging said coupling links 22 with said wheel shafts 15, the springs 20, areicompressed slightly toward said Wheelshafts 15', until the ends of said shafts come opposite to and are projectedintQ said. round openings,

of, in said cou lings 22, and when the portions 0, of sal shafts wlnch are narrower than the main portion, areadjusted in line with the narrower openings, 6, of the couplings 22, the springs 20 are released, when the couplings will rise and the portions of the couplings 22 at the sides of the narrow openings 6, will clasp the shaft 15 at the narrow portions, 0, which will prevent the couplings 22 from becoming accidentally disengaged froin the ends of said wheel shafts 15, will hold them in place and prevent them from rotating.

23 designates, a yielding. support in the form of a spring wire, one end of which is secured to the outside of the end, a, of the body 1, and 24 designates a dust pan provided at each end, and near its inner edge with a trunnion 25, which trunnions extend through openings 3 and '4 in the ends, a, of the body 1, and one of-said trunnions at one end extends through the opening 3 and is supported by said yielding support 23, and

the trunnion at the other end'of said dust pan extends through the. opening 4',and is supported by a link 27, the trunnion being preferably flattened to enter the elongated slot 26 in the link 27, so that when trunnio'n is inserted in the elongated slot 26 of the link 27, it will besecurely held in said link from accidental disengagement. And saidlink 27 is suspended from the adjacent wheel shaft 15 by the latter being projected through the elongated slot 26, in said link 27. There are two of the dust pans 24 both supported and constructed in the manner just described except that the yielding support 23 and link 27are reversed, that is where the link 27 supports the trunnion 25 at one end of the dust pan, the trunnion on the end of the opposite pan at the same end of the case or body is supported by the yielding support 23.

28- designates a rod secured in the outer edge of each of the dust pans 24, and the outer edge of each of said dust pans 24 rests in a groove, f, in the inner lower edge of the side of the body 1. One end of said rod 28 extends through an opening 29 in one of the ends. a, of said body 1'.

3O designates levers pivoted on pivot pins 31 secured to the ends, a, and 32 designates a connecting wire one end of which is secured to the lever 30 midway between its ends and the other end of said Wire is con nected to the end of said rod 28 which projects beyond the end, a.

33 designates supplemental ends, spaced apart from the ends, a, of the-case or body 1 and supported by angular extensions, 9', secured to said body;

34 designates arms which are pivoted at one end by pivot pins.35 secured to the sides of the supplemental ends 33, adjacent to the ends of the body 1; and h, designates a raised portion of each of said pivotal arms 34 which is struck up to form the shoulders set screws which each end of the brush i, in which elongated slots or openings 36 are formed, and in these raised portions, h, the elongated slots or o enings 37 are formed.

38 designates cylin rical bearings for a brush spindle 39, and in the ends of said brush spindle 39 are sockets 40, for releasing said bearings 38. I

k designates shanks with which the bearings 38 are provided, and said shanks, is, project through the elongated slots or openlugs 37 in-the raised portions, h, of the pivotal arms 34.

41 designates springs each secured at one end to said pivotal arms 34, and the other ends of said springs ext-end through the elongated slots 36 in the shoulders, z', and

over the shanks, k, of the brush spindle bearin s 38, to hold them in engagement with said arms 34. 42 designates plns fixed on and near the ends'of said pivotal arms 34.

43 designates levers ivoted on pivot pins 44 secured in the supplemental ends 33. 45 designates slots formed in the ends of said levers 43 adjacent to the ends of the pivotal arms carrying the pins 42.

46 designates elongated radial slots formed in the supplemental ends 33. 47 designates extend through said radial slots 46 and are screwed into screw threaded sockets in the upper or outer ends of the levers 43; and, m, designates the lower curved edge of said lever 43.

48 designates journals rigidly secured in spindle 39, which journals 48 extend a short distance beyond the ends of said brush spindle 39 and into the sockets, 72, provided in the cylindrical bearings 38 thereby holding the ends of said brush spindle 39 and bearings 38 in line when in operation.

49 designates bridge wires which extend across and close the lower outlets of the openings, 3, in the ends, a, to prevent the trunnions 25 of the pans 24, which are supported by the spring supports 23, from-fall ing out of the openings 3, when dumping said thrown to the position indicated by the dotted lines in Fig. 3, to dump the sweepings by moving the levers 30 outwardly, and

closed again by throwing the levers into the position shown infull lines in Fig.2.

When not in operation or when no pressure is applied to the sweeper, the body 1, wheels 16 and dust pans 24 are in the position shown in Fig. 2, but when pressure is applied to the sweeper the body I lowers more or less, according to the pressure applied to it, to the position shown in Fig. 5. And the wheels 16 resting on the carpet, and the inner edges of the dust pans 24 being supported at one end from the shafts 15, by the links 27, as hereinbeforge described, it will be impossible for the dust pans to be further lowered, consequently the inner a, at the upper end dust pans 24. The dust pans 24 are' edges of the dust pans 24 are justabove but clear from the carpet, and in the best possible position to catch and hold the dust and dirt on the spindle 39.

swe t u b the brush 0* P y a y When t e greatest pressure is on the l, the latter is not of the slots 3 and 4, abut against said trunnions 25, and there is left a clearance to ermit the trunnions 25 to rise independenly 1n the openings 3 and 4.

lowered so that the ends,

The outer edge of the dust pan 24, is at a higher elevation from the carpet than the inner edge and the inner 'edge of said dust pans underall normal conditions will al-..

ways be close to yet clear of the carpet, no matter .how heavy the body 1 of the sweeper, at the same time said pans 24 are so supported that they will automatically and instantly adjust themselves while the sweeper is in motion to pass over and take up apiecejof coal or other similar large or hard substance on the carpet, without spilling or in any Wayinterfering with the dust or dirt which has been previously gathered in the dust pans.

The brush spindle 39 is supported and revolves freely on the cylindrical bearings 38 at both ends of the machine, and the parts '39 and 38 are held in alinement by the mile 48 as hereinbefore described. The bearings 38 are provided with shanks k which extend through the vertically elongated slots 37 in the pivotal arms 34, one of which is pivoted on the supplemental ends 33 at both ends of the machine, and a spring 41 mounted on each of said pivotal arms 34 extends through the shank 7c of each of said bearings 38. These springs 41 hold said shanks, k, in the lower ends of the vertically elongated slots 37 so that said bearings 38 together with the brush spindle 39 may be adjusted with said pivotal arms 34, at the same time the vertically elongated slots 37 together with the springs '41 permit an independent ver-- The levers 43 one of which is pivoted on 'each of the supplemental ends '33, and each of which is provided with a slot 45, engages with the pins 42 on the pivotal arms 34, so

that by loosening the set'screws 47 and adjusting them in the radial slots 46 in the supplemental as well as the brush spindle 39 may be regu: lated to hear more or-less on the carpet, or to be gradually lowered as the brush, '1", wears, and when properly adjusted it is rigidly held in this position by tightening the set screws 47. 7

When pressure is applied to the sweeper,

the effect is to lower said body 1 and more or less, according to the pressure applied,

and as the body 1 is lowered the springs 20' are also lowered which action throughthe couplings 22 presses said wheels inward on the pressure may be on ends 33, said pivotal arms 34 39, and the greater the pressure on the sweeper, the greater will be the pressure of the wheels 16 on the enlarged portions, t, of said brushspindle 39, consequently the better will be the contact therebetween' and the more positive the rotation of said spindle 39. The Wheel shafts 15 being prevented from rotating by the flat portions, 0, thereof engaging with the couplings, 22, as described, all possibility of thread, fine fuzz, or other similar material winding around said shafts 15, and interfering with-the operation of the machine, is avoided and completely prevented. The journal 48 being entirely covered, and the bearin 38 being located in the socket in the end o l said brush spindle as shown in Fig. 10,and held stationar as described, anypossibility of any rave ings or threads winding around said journals 48 or" bearings 38 is avoided and completely pre- 7 vented.
