I H U @am/ 147176 N NITE "rats DANIEL LITTLE, OF CORNWALL-ON-THE-HUDSON, NEW YORK.
ERASER-C LEAN ER.
SPECIFICATION forming part of Letters Patent No. 667,540, dated February 5, 1901.
Application filed October 31, 1900. Serial No. 35,012. (No model.)
To aZZ whom it may concern.-
Be it known that I, DANIEL LITTLE, a citizen of the United States, residing at Cornwallon-the-Hudson, in the county of Orange and State of New York, have invented certain new and useful Improvements in Eraser-Cleaners, of which the following is a specification, ref erence being had therein to the accompanying drawings.
My invention relates to improvements in eraser-cleaners3 and the object of my invention is the provision of a simple, inexpensive, and practical device by means of which blackboard-erasers may be thoroughly cleaned in a rapid manner and avoid the dust resulting from the cleaning of such erasers.
To attain the desired object, my invention consists of an eraser-cleaner embodying novel features of construction and combination of parts, substantially as disclosed herein.
In order that the details of construction and the operation of my eraser-cleaner may be fully understood and its many advantages be fully appreciated, I have illustrated in the accompanying drawings an eraser-cleaner constructed in accordance with and embodying my invention.
Figure 1 represents a perspective view of my eraser-cleaner closed ready for use. Fig. 2 represents a similar view with the eraserholding boards removed, and Fig. 3 represents a sectional view with the erasers in position to be cleaned.
The casing or housing of my device is of peculiar and novel construction,and consists of the end pieces A, which taper toward the top and are connected by the top piece B, the lower vertical pieces O,and the bottom D,thus leaving the open spaces which are arranged at an incline and in which fit and are secured the two boards or strips E, to the inner wall of which are secured by suitable clips F the series of erasers G. From this construction it will be seen that my housing or casing is of substantially conical form and that the removable boards will hold a number of black board-erasers to be cleaned, and mounted in the lower portion of the housing is the shaft H, carrying at one end the gear-wheel J, with which meshes the driving gear-wheel K, having the crank or handle L for revolving said wheel is arranged in a circular opening R of the frame and draws or exhausts the dust from the erasers and conveys it through the chute S, as is evident. Also meshing with the driving gear-wheel is the gear-wheel'l, which is arranged on the shaft U,which is provided with a crank or arm V, and to this arm is connected the lower end of the link or pitmen W,the upper end of said link being connected to the arm X, secured upon the rock-shaft Y, which rock-shaft has secured to and depending therefrom a series of paddles or boaters Z, said beaters being perforated to allow the dust to pass through, and the heaters may be removable or rigid upon the rock-shaft, as found desirable.
From the foregoing description, taken in connection with the accompanying drawings, the operation of my invention will be apparent, and it is obvious that the erasers are secured by the clips to the inclined boards and that the rotation of the driving gear-wheel imparts a rocking motion to the shaft which carries the heaters, which brings the boaters quickly and forcibly against the erasers and knocks the dust from them, and the same rotation of the driving-gear also revolves the shaft which actuates the exhaust-wheel, this drawing the dust from the casing and carrying it away through the chute or conveyor, and thus the erasers are speedily and perfectly cleaned and no dust can escape into the room, thus insuring a practical, useful, and very much needed requisite in school-rooms and other places where erasers are used.
I claim- 1. An eraser-cleaner, consisting of a casing or housing having means to accommodate and secure a series of erasers'on opposite sides of said casing, a series of heaters or paddles for striking the erasers to knock the dust therefrom, and means for operating the boaters.
2. An eraser-cleaner, consisting of a casing adapted to receive erasers on each side thereof, fastenings for detachably securing the erasers to be cleaned, and a series of reciproeating heaters adapted to strike the erasers alternately on each side of the casing to knock the dust therefrom.
3. An eraser-cleaner, consisting of a casing adapted to hold a series of erasers, fastenings for detachably holding the erasers to be cleaned, a series of heaters for striking the erasers to knock the dust therefrom, means for conveying the dust from the casing, and mechanism for operating the heaters and the dust-conveyer.
4. An eraser-cleaner, consisting of a casin g or housing, removable hoards having means for holding the erasers, a series of heaters for alternately striking the erasers on said hoards, suction devices for conveying the dust from the casing, and means for operating the heaters and the suction devices.
5. An eraser cleaner, consisting of a housing having means to receive and hold a series of erasers on each side thereof, a shaft carrying a series of paddles or heaters to strike the erasers, means for reciprocating the shaft to bring the heaters against the erasers, and operating mechanism for said shaft.
6. An eraser-cleaner, consisting of a casing or housing, a shaft carrying a series of heaters, mechanism for rocking said shaft, another shaft connected with and operating a fan or suction device, and a series of erasers secured in the casing and adapted to he struck by the heaters to knock the dust therefrom.
In testimony whereof I aifix my signature in presence of two witnesses.
DANIEL LITTLE.
