OHAUNGEY M. LOTHROP, OF NORWOOD, ASSIGNOR OF ONE-HALF TO EDWARD HATCH AND J OHI\ O. HATCH, OF BOSTON, MASSACHUSETTS.
BLOTTlNG-PAD.
SPECIFICATION forming part of Letters Patent No. 234,878, dated November 30, 1880,
Application filed September 23, 1880.
To all whom it may concern Be it known that 1, GHAUNOEY M. L- 'lHROP, of Norwood, in the county of Norfolk, State of Massachusetts, have invented a new and useful Improvement in Blotting- Pads; and I hereby declare the following description to be as full, clear, and exact as will enable one skilled in the art to which my invention pertains to make and use the same,
reference being had to the accompanying drawings, forming apart of this specification, in which- Figure l is a view, in perspective, of my improved blotting-pad. Fig. 2 indicates the 1 pad in perspective, the movable section turned down to admit and secure the blotting-paper in strips. Fig. 3 is a vertical longitudinal section through line m. Fig. 4 represents the construction of the hinge combined with the spring, and exhibiting the adjustment of the latter in its lock or catch.
Like letters of reference indicate like parts in the various figures.
My invention particularly relates to that class of small hand-blotters in common use, but can with equal facility be used as an eraser on blackboards and for similar purposes.
It consists in an ingenious construction and 0 combination of parts through which a more effectual and cheaper device is secured than is now in use.
Referring to the drawings, a indicates the floor or slab, constructed of wood or other 5 suitable material, preferably rectangular in shape, and of proper proportions and strength to receive the two blocks of Wood b b, forming the principal body of my device. One of said blocks (indicated at b) is permanently secured, or may be constructed integral with the floor or slab a.
To the block b is attached its counterpart I), secured at its thicker end to the corresponding end of the block b by a combined hinge and spring, (comprehensively shown at c, Fig. 4.) The under or working faces of said blocks are shaped in the ordinarily convex (N0 model.)
manner, and have permanently attached sheets of felt or any suitable substance to form a cushion for the reception of the blotting or absorbent material.
Along the edges of the outer and thinner ends of the blocks b b are cut deep slots or grooves 01 (1, running from side to side, and. of uniform width and depth. These slots are for the reception of the ends of the paper blotters 66, which, for the purpose of insertiomare brought together, several in number, and the ends introduced into the slots or grooves, to facilitate which operation the block b is liber- 6o ated from the floor a and allowed to fall to such an angle as may insure the easy adjustment of said blotters, as in Fig. 2. The block bis then brought up to its normal position against the floor a, to which it is secured through the medium of the lock f and spring 9, made in one piece with the movable part of the hinge or butt 0.
In the adjustment (as above) of the block I), the tension produced upon the blotting-paper 7o insures an even and firm surface upon the felt cushion. (See Fig. 1.)
The construction of the spring and binge is clearly shown in Fig. 4.
In the construction of the lock or catch f, I usually form the same from sections of metal pipe, of suitable length and diameter, with overturned or upset edge It andscrew-threads 'i out upon its outer circumference. The lower or bottom edge of the metal lock is turned inward entirely around the lock, thus forming at any point of its circumference a projecting lip, j, for engaging with the end of the bent spring g. The circular opening 70 is of sufficient size to freely admit the bent end of the spring g, but yet to limit the movement of the same by the finger in the act of unlocking, so that the tension of the spring may not be impaired by its frequent use.
I lindicate borings in the wood, made simo ply for the purpose of securing lightness in the construction.
Having thus explained the nature and construction of my invention, what I claim is- 1. The improved blotting-pad frame herein described, consisting of the rigid and movand for the purpose described. able slotted blocks I) I), lock f. combined In testimony whereof I have signed this spring and hinge g c, all arranged to operate specification in the presence of two subscribsubst-antially as and for the purpose set forth. ing witnesses.
2. In combination with the slotted blocks 1) OHAUNOEY M. LOTHROP.
Z), the hinge 0, provided with aprojecting arm \Vitnesses: terminating in a bent spring g, the screw- H. E.REM1CK, lock f, and its projectinglip j, all arranged to EDWARD HATCH.
operate in unison therewith, substantially as 10
