i tjrZNvENToR` l a* ,'a mail ATTORNEY Patented Aug. 17, 1937 UNET STATES PATENT OFFICE 1 Claim.

The invention relates to a blackboard eraser holder and more especially to a device for effecting cleaning of blackboard erasers.

The primary object of the invention is the provision of a device of this character, wherein a number of blackboard erasers can be conveniently supported so that the same can be quickly cleaned through the use of a paddle, brush, Vacuum cleaner or other contrivance, the holder for the erasers being of novel construction.

Another object of the invention is the provision of a holder of this character, which is eX- tremely simple in construction, thoroughly reliable and efficient in its purpose, enabling convenient and easy cleaning of erasers when held therein, strong, durable, and inexpensive to manufacture.

With these and other objects in View, the invention consists in the features of construction, combination and arrangement of parts as will be hereinatfer more fully described, illustrated in the accompanying drawing, which discloses the preferred embodiment of the invention and pointed out in the claim hereunto appended.

In the accompanying drawing:

Figure 1 is a top plan View of a holder constructed in accordance with the invention.

Figure 2 is a vertical sectional View thereof.

Figure 3 is a sectional View on the line 3 3 of Figure 1 looking in the direction of the arrows.

Figure 4 is a sectional view on the line 4 4 of Figure l looking in the direction of the arrows.

Figure 5 is a plan view of a brush cleaner.

Figure 6 is a side elevation thereof and partly broken away.

Similar reference characters indicate corresponding parts throughout the several views in the drawing.

Referring to the drawing in detail, the device comprises an open frame I0 made from a single strand of rigid wire and in this instance is of square contour having at one end thereof centrally of said frame a handle I I for manual handling thereof. Bridging the frame transversely thereof are bands I2 preferably made from metal straps, these having the eye ends I3 embracing the opposite sides of the frame, andsuch bands are in spaced parallel relation to each other. These bands I2 are formed with outstruck bi-ghts I4 saddling grating bars I5 having their ends joined with the frame ID at the front and rear ends of the same, these bars I5 being arranged in spaced relation to each other and at equal distances apart. The bars I5 are seated in the bights I4 to overlie substantially U-shaped resilient clips i5 which are riveted or otherwise made fast to the bands I2 and located in rows across the frame l. Removably engaged in these clips are blackboard erasers I'I so that a group of these erasers can be held to enable convenient cleaning thereof by paddle action in the use of the paddle I8 carrying at one end a brush I9, the paddle being perforated at 20 for the free passage of dirt and other foreign matter through the paddle when in use. The erasers II can also be cleaned by a vacuum cleaner or otherwise if found convenient.

The handle II is provided with an eye terminal 2l to permit the hanging of the holder upon a nail or the like when not in use. Likewise, the handle end of the paddle I8 is formed with a hole 22 permitting it to be hung upon a nail or the like when not in use.

At the front end of the frame Il] is a scraper blade 23 which is suitably made fast at 24 to the bars I5, and this scraper blade enables the scraping of the erasers or the scraping of the brush I9. The paddle I8 can be utilized for cleaning the crayon rack of a blackboard.

'Ihe frame Ill when carrying the erasers I1 will permit the beating of the erasers for the removal of chalk or other matter therefrom for thorough cleaning of the same.

What is claimed is:

An article of the character described comprising an open frame made from a single strand of rigid wire and of substantially square formation, a handle built at one end of the frame, bands bridging the frame and each having eye ends embracing the opposite sides of the frame, said bands being arranged in spaced parallel relation to each other, outstruck bights formed on said bands, grating bars saddled by said bights and joined with the frame, and substantially U-shaped resilient clips for detachably holding articles made fast to the bands at the base of the U and arranged in rows in overlying relation to the said bars for holding the same seated in the bights.
