pans by a force to be supplied by. a human thumb and' one finger, andwithout disturbing the equilibrium of the sweeper body when supported by the handle alone; also to minimize the force required to overcome a given spring pressure employed to maintain the pans closed during sweeping operations.
Another object is to provide means for retaining the dust pans in an open position while discarding collected. dirt particles without adding additional parts to accomplish the desideratumandiindepen'dently of the force employed to effect the opening.
Still further objects or advantages, subsidiary or" incidental to the aforesaid objects; or resulting from the construction. or'operation of the invention as it may becarried into effect, will become apparent as the saidinvention is hereinafter disclosed.
Drawing The invention is more particularly described and ascertained hereinafter, by way of example, having reference. to the accompanying drawing wherein: v I V Figure 1 is an end. View of a carpet sweeper housing with sections of. the .end cover and the end wall cut away,
axles. removed to more clearly disclose the details of the dumping" mechanism for the dust collecting pans.
Fig. 2 is a bottom view of in its entirety, except that only a portion of the length of the sweeper is shown.
Fig. 3 is directed to a minor modification of the manually actuated rod to provide a means for locking the dust pans in an open position.
Fig.4 is a modification of Fig. 1 to illustrate a practicable rearrangement of the identical parts to provide means to yieldingly retain the pans in either the open or the closed position independently of the operating force.
Fig. 1 substantially Structure and operation Numeral I indicates the end wall of the as well as thewheels and their sweeper housing, ll a plate attached'thereto and which is organized to support wheels, axles and their appurtenances which are not shown. Bearing l2 is a bushing fashioned" witha shoulder and riveted on to the plate so as to become a2? permanent part thereof to support shaft 13, to one end of which is keyed lever or arm M, while lever or arm I5 is keyed to the other end; It will be noted that the ends of the arms 14 and l5 adjacent shaft l3 have been formed with $150 projecting areas which serve. as collarsfor the, shaft and abut the ends 'of the bearing 12- and thereby completely close same. This is obviously an enduring bearing of aivery'high-order wherein the projecting areas ofthe arms prevent any egress of'dust from thedust chamber-even during rapid rotationof the-brush when the air ishighly agitated. Tothe lower end of lever I5, push bar I 6 is pivotally connected by pivot llwhile the outer endof bar I6. is slot l8 formedin cover lfl which isremovabl-y attached to the end wall l-0.- Notch-,lfib of bar It in the modification shown in Figure3 is solocated that it can engage the margin ofslot l8 and thereby look all the moving parts of thee dumping apparatus-in the incident position, with r the result that the pans will be held in the open position independently of the actuating force. A slight vertical pressure willrelease these parts to respond to the action of spring 2 l*to eflectsg closing of the pans, which is dealt with hereinafter. i
Arm I 4 is formed with a hook or projecting lug which at all times carries the apex ofv inverted V shaped dump lever spring of said spring have a right angle bend to form. arms 22, 23, each one, being disposedinto upturned edges'of dump lever pans 24, .25; These in turn are carried-on. pivotsorshort shafts 26,121 which are permanently attachedto'plate I l;
By lodging the ball of a human linger on the inner wall We of the cover and the thumb against the arm lBa of bar l6, and exerting a mild squeezing action, bar It travels in a path substantially parallel to the horizontal and moves lever I5 about its axis which in turn rotatesshaft l3 suiiiciently to thereby cause arm M to travel up- Ward and pull spring 2| from its lowerdotted rest position to the upper dotted position and thereby cause the dust pans 24, 25 to open and assume the position indicated by the dotted lines representing same in Fig. 1. Upon release of the pressure, the spring will return all the parts to their normal position. 1 V
In Fig. 4 the lug 20 is sufliciently closed to slidably u ported by p 2| whilev the endstf retain the apex of spring 2| against force applied in either direction, which is employed to push or pull the ends of the spring over the center line described through the centers of pivots 26, 21, after which the spring toggles and forces the pans to the closed or open position. This structure differs from that disclosed in Fig. 1 by a minor rearrangement and relation of the travel of arm M and/or the length of spring 2|.
Scope The drawing employed to disclose this invention and the specification thereof; is in terms of my improvements as applied to theconventional housing consisting of assembled pieces of wood. In the application of this invention toa unitary drawn sheet metal housing, the separate pieces "housing, comprising a' shaft pivotally mounted I cooperating with the bearing to in a bearing associated with said end member, an
arm keyed to said shaft, said arm engaging the central portion of a spring cooperating to open and close apair of dust pans, and means employed to actuate" said mechanism, including another arm keyedto said shaft, said arms circumferentially projecting beyond said bearing and retain the shaft in a selected position and completely close the ends of said bearing. 7 v v f 2. A dumping mechanism attached to a vertically disposedend member of a carpet sweeper housing, comprising a shaft pivotally mounted in a bushing associated with said end member, an
t arm keyed to the inside end of said shaft and circumferentially projecting beyond said bushing, said arm engaging the, central portion of a spring cooperating to open and close a pair of dust pans, and means employed to actuate said mechanism, including another arm keyed to said shaft, said inside arm cooperating with the shaft and bushing to effectivelyprotect said bushing against the egress'of dust from saidhousing.
"3(A dumping mechanism attached to avertically disposed end member of a carpet sweeper housing, comprising a shaft pivotally mounted in a bearing and extending through said end tically disposed end member end member of a carpet sweeper housing,
member, a short arm keyed to one end of said shaft, said arm engaging the central portion of a spring organized to open and close a pair of dust pans, means employed to actuate said mechanism, including a long arm keyed to saidshaft, said arms circumferentially projecting beyond said bearing and cooperating with the bearing to retain the shaft in a selected position and completely close the ends of said bearing.
4. A dumping mechanism attached to a verof a carpet sweeper housing, a removable cover attached to and substantially covering the vertical end of said housing and surrounding a portion of said mechanism, said mechanism comprising a detachable chassis plate, and a shaft pivotally mounted in a bushing lodged in said plate, an arm keyed to said shaft, said arm engaging the central portion of a spring cooperating to open and close a pair of dust pans, and means to transmit force to actuate the said mechanism including another arm keyed to said shaft and connected to a bar extending through said cover.
