Specificatiel's Patent. Patented Sept. 1P2, jlmlfi,
Application filed August 14, 1915. Serial No. 45,504.
To all whom it may concern:
Be it lmown that I, CLIFFORD C. DANCE, a citizen of the United States, residing in the city and county of Denver'and State of Colorado, have invented certain new and useful Improvements in Vacuum-Cleaners; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and carpet or other article, with such rapidity of movement as may be desired; and the other an oscillatory beater adapted to act upon the article to be cleaned in a beating or whipping capacity, whereby any dust, dirt or foreign matter which the oscillating brush mi 'ht fail to remove will be loosened and thus rought into such position or condition as to be extracted by the brush.
In my improvement a motor of any suitable character may be employed. I prefer to use an' electric motor arranged in such a manner that the operating shaft shall imart the oscillatory movement to the brush y any suitable connection. It will usually be necessary to connect the motor shaft with the brush through the instrumentality of suitable speed reducing devices, since the speed of the motor shaft would ordinarily impart too rapid movement to the brush. This feature, however, is old in the art and nothing novel is claimed thereon.
Having briefly outlined my improvement, I will proceed to describe the same in detail, reference being made to the accompanying drawing in which is illustrated an embodiment thereof.
In this drawing,-Figure 1 is a perspective view of a vacuum cleaner equipped with m im rovement. Fig. 2 is a sectional view 0 the body of thestructure, the section being taken'vertically through the casing of the machine and showii on a larger scale than in Fig. 1. Fig. 3 is a perspective view of the beater shown in detail. Fig. 4 is a similar view of the brush member of the structure. Fig. 5 is a vertical section taken through the brush head.
The same reference characters indicate the same parts in all the views.
Let the numeral 5 designate the casing of the cleaner upon which is mounted a motor 5 whose shaft 7 is journaled in the casing, 1ts lower extremity beingequipped with an operating wheel 8, the latter being connected by means of a belt 9 with a wheel 10 having a crank pin 12 which is connected by means of a pitman 13 with the brush 14;, the brush holder 15 being provided with a pair of spaced lugs 16 with which the forward extremity of the pitman is connected as shown at 17 These lugs are perforated to receive a pivot pin which passes through registering openings in the lugs 16 and the forward extremity of the pitman. The brush holder is trunnioned in the casing by means of journals 18 with which the opposite extremities of the said holder are equipped.
As shown in the drawing, the brush head 19 is inserted in the holder 15 which is channel shape and open at the bottom for insertion of the said head. The holder is provided with threaded openings 20 adapted to receive set screws 21 for the purpose of securing the brush and holder in suitable cooperative relation. 1
The bristles 22 of the brush extend downwardly, into engagement with a set of fingers 23 which constitute heaters and are arranged to extend across an opening 2 1 in the bottom and at the front of the casing through which the dust or other dirt removed from the carpet or other fabric bemg cleaned; passes in response to the suction induced by the fan 25 or other suitable, suction inducing device. These beater fingers 24 are secured to a rock shaft 26 whose opposite extremities are journaled in the opposite ends. of the casing. Connected with the center of this rock shaft is an arm 27 which extends upwardly and is rearwardly curved, its rear extremity having a recess 28 in which is seated the lower extremity of a spiral spring 29 whose upper extremity engages the top of the casing. The tension of this spring normally acts upon the rear-extremity of the arm 27 to cause the beater fingers 23 to assume their lowermost position or that indicated by the dotted lines in Fig. 2. The rear extremities of these fingers engage a lip 30 formed on the forward edge of a bottom plate 31 of the casing.
The arm 27 is provided near its rear extremity with a depending lug 32 which projects into the path of the upper extremlties of the lugs 16 of the brush holder as the latter is oscillating whereby an oscillatory movement is imparted to the rock shaft 26 and consequently to the beater fingers 23 whereby they are caused to act upon the carpet, rug or other fabric as it is drawn into the opening 24 by suction induced by the fan as hereafter explained. In other words, the upper extremities of the lug 16, during the oscillating movement of the brush, move in an are indicated by the dotted line 33 in Fig. 2. The front and rear positions of the brush during its oscillatory movement are respectively indicated by dotted lines 34 and 35. From this it will be understood by an inspection of Fig. 2 of the drawing, that the upper extremities of thelugs 16 of the brush holder, are caused to engage the lug 32 of the arm 27, once during each stroke, or twice during each complete oscillation of the brush. Hence, during-the movement of the brush, partial rotations are imparted to the rock shaft in reverse directions bythe action of the ears 1 16 upon the lug 32 of the beater arm. It
will be understood from this explanation and from an inspection of the drawing that lug 32 and the upper part of the arm 27 of which it forms a art, are alternately raised and release the upward movement being imparted by engagement of the ears 16 while the recoil of the spring 29 serves to impart the downward movement or the movement in the opposite direction. Thus it will be understood that during the oscillation of the brush, a similar movement is imparted to the beater fingers 23, and in this way the said fingers cooperate with the'brush in performing the cleaning function.
When the machine is used a dust receiving bag or receptacle 36 is connected with the rear extremity of the casing, which is provided with a nozzle 37 for the purpose, the said nozzle having a flange 38 to facilitate the connection of the forward extremity of the dust bag, the rear extremity of this bag being connected as shown at 39 with the handle 40 of the device through the medium of a short rope or cable 41, the upper extremity of this rope being connected with the handle as shown at 42.
When the device is in operation, as illus trated in the drawing, the shaft 7 is rotated by the motor 6, which-is of the electric type, its current being supplied through the medium of conductors 43 which may be connected with the incandescent light circuit of the house where the machine is employed. The rotation of the shaft 7 imparts rotary movement to the fan 25, and also through the medium of the pulley 8, the belt 9, the crank wheel 10 and the pitman 13, to the brush 14 and consequently to the beater fingers 23 as heretofore described. The suction induced by the rotation of the fan, produces a strong current of air which enters the opening 24 and passes thence through the front part of the casing, rearwardly and up through the opening 44 into the fan chamber 45 and thence into the bag 36, thus drawing the dust and dirt from the carpet or other fabric and depositing it in the bag.
Having thus described my what I claim'is,-
