IMPROVEMENT IN MOP-HEADS.
Specification formingpart of Letters Patent N0.15S,033, dated December 22, 1874; application filed September 29, 1874.
To all whom it may concern:
Be it known that we, OHARLns B. CLARK, of Buffalo, in the county of Erie and State of New York, and JOHN K. CLARK, of the same place, have invented a new and useful 1mprovement in Mop-Heads, of which the following is a specification:
This invention is illustrated in the accompanying drawing, in which Figure l is an elevation of a mop-head containing my invention. Fig. 2 is an inverted "iew of my split three-part collar detached, the nut being removed therefrom. Fig. 3 is alike view of the nut, detached. Fig. 4 is an interior view of the upper half of the split collar, inverted. Fig. 5 represents the interior of the 'two divisions of the lower part of the split collar. Fig. 6 is a cross-section of the collar, taken in the plane of the line a: 00, Fig. 2, the nut being put in place.
This invention relates to the class of mopheads which uses a collar split transversely to its axis; and it consists in dividing one of the halves of the split collar (the lower one in this example) into two divisions, which articulate with the other half by means of a nib and socket provided in the inner faces of the collar, and angular projections formed on the inner surface of the upper half of the collar, which projections are interlapped by the ends of the divisions of the other half.
By this construction I am able to mold and cast the parts of the collar with facility, and the nut is placed and retained in the collar without difficulty.
The arms of the collar are fastened together by rivets or other suitable fastening device after the nut is inclosed.
The letter A designates the stationary jaw and hollow shank of a mop-head, the shank being provided with two series of short parallel ribs, K, with which the nut G of the movable jaw engages, the two series of ribs being separated at both ends of the ribs by smooth interspaces, as is shown in Letters Patent No. 128,711, dated July 9, 1872. The letter B designates the movable jaw, the collar of which is split transversely to its axis,
forming an upper and lower half, a b, the lower half, b, being divided in the direction of its axis into the parts 1 2. The upper half, a, of the collar consists of a ring-shaped piece, having an inwardly-projecting flange, a, so as to form within it a rabbet, (1, in which the lugs of the nut can turn freely, and on its lower surface or rim, at points opposite to each other, and about midway between the arms 6 e are formed angular projections ff, one of which is seen in Fig. 1. The divisions 1 2 of the half I) of the collar when united form also a ring-shaped piece provided with arms 0 e, which are counterparts of the like arms in the part a. The inner circumference of the part b, when its divisions are united, is of such a diameter as to allow the nut to revolve freely within it, and by overlapping the rabbet (I, when its divisions are placed in their proper position under the part a, it forms the circular groove 9 within the rabbet, in which groove the lugs h h of the nut are confined in such a manner that the nut is held securely and allowed to turn freely in the collar. The divisions 1 2 are counterparts of each other. Each is provided with a spur, i, at the inner end of its arm 0, which spur is arranged to fit in a socket, i, made in the part a. The outside of the ends of the semicircular divisions 1 2 are cut away at j j on an incline, so as to fit the corresponding inclines of the projections f of part a, leaving flanges m, which fall within the projections f, and which, in conjunction with the spurs 'i and sockets 2", operate to keep the parts a b fitted to each other, in which condition they are secured by rivets through the rivet-holes a. The lugs h of the nut, by means of which the nut is held in the collar, are arranged on opposite sides between the thumb-pieces 0 0, and on either side of the thumb pieces are semicircular flanges p p, which overlap the collar, and serve, in conjunction with the lugs, to keep the nut and the collar in proper relations with each'other.
What we claim as new, and desire to secure by Letters Patent, is-- l. The three-part collar, consisting of the half a and the divisions 1 2, composing the In testimony that we claim the foregoing half I), in combination with the nut Gr, all 0011- we have hereunto set our hands this 21st day structed substantially as described. of September, 1874:.
' 2. The angular projections f of the half a CHARLES R. CLARK. of the split collar, in combination with inter- JOHN K. CLARK. lapping flanges m formed on the divisions 1 2 Witnesses: of the other half I) of the collar, with the EDWIN L. FERGUSON,
counter-inclines j j, substantially as described. WM. W. CLARK.
