CLUTCH.
Specification of Letters Patent.
Patented July 30, 1907.
. Application filed April30.1906. s eam. 314,431
To all whom it may concern:
Be it known that 1, James C. Dawson, a citizen of the United States, and a resident of the city of St. Louis, State of Missouri, have invented certain new and useful Improvements in Clutches, of which the follow-- ing is a. specification, and which are illustrated in the accompanying drawings, forming a part thereof.
This invention relate s to a double-acting clutch block adapted to run upon a rod and normally gripping the rod so as to be immovable in either direction.
The invention comprises a chambered block or box within which'is housed a pair of clutch members,
which respectively grip the bar under the influence of pressure applied in opposite directions; and more specifically it consists in the device hereinafter described and which is illustrated in the accompanying drawings, in which i Figure 1 represents a longitudinal central section of the clutch block as applied to the post of a file binder; Fig. 2 is a perspective of the block as applied to a rod;
Fig: 3 is a view similar to Fig, 1, showing a modified theclutch being. applied for the purpose of binding a block of leaves 12 to the base plate. The rod 11, it will be understood, represents any rod or pair of rods in 'alinement upon which it may be desired to utilize the clutch-block. The clutch block comprises a' box or chambered block 13, having a cover 14 permanently secured by compressing the upper edge'oithe side wall of the box into an annular channel in the periphery of the cover. Two clutch members 15, 1.6, are used, and take the form of plates apertured in line with the axial apertures in the top and bottom of the blocktlirough which the rod 11 is inserted. At one side of the aperture of the plates a biting edge is formed, as shown'at 17,- 18 for engaging the post. The inner ends of the plates 15, 16, abut against the side wall of the block 13, the one in proximity to the cover and the other to the bottom of the box. The opposite ends of the plates extend through apertures in the side wall of the block somewhat removed from the cover and bottom, and
hence theplates are inclined to the axis "of the box.
Inthe construction illustrated in Fig. 1 the inner ends of the plates are at the same side of the box and hence their outer ends are inclined towards each other, and their gripping edges areupon the same side of the post. A spring 19', shown inthis figure as helical in form, reacts-between the two plates and normally holds them both in gripping contact with the rod. Pressure upon the block in either direction in line with the post will tend to bring one of the plates perpendicular to the post, and hence cause it to grip thelatter firmly, and as the length of that portion of the plate lying between its gripping edge and its inner end is greater than the distance from the surface of the post to the side of the box, this action positively holds the block against movement. The block may be freely moved in either direction by pressing the outer ends of the clutch plates toward each other, or it may be moved in one direction by first pressing the plate adjacent its opposite end against the resistance pithespripg.
. In the construction illustrated in Fig. 3, the blo'clZ 20 is of the same general form of construction as the block 13, but may be of less length. The clutch plates 21, 22, are of the same form as the plates 15, 16, but are differently disposed within the chamber of the block, in that their ends are in reverse relation, their inner ends being at opposite sides of the chamber, as are also their outer ends, the two plates lying normally in parallel planes. The spring reacting between the two plates to hold them in engagement with the rod may be of any desired form, but, as shown at 23, is approximately fiat and has one end, 24, hooked into a suitable aperture in one of the plates, as 22, its opposite end lying against the face of the other clutch member, as 21.-
Whenthis form of spring is used it is apertured in) 'fit loosely around the rod 11.
The form of construction illustrated in Fig. 3 is of advantage over that shown in Fig. 1 in that it is less bulky, though itisnot-socerwenientnt manipul ti n e a u \7 1 v or the purpose of sliding it either way upon tneron.
For use in connection with a file binder thisform is convenient, as in pressing it down it would require only that the upper clutch plate be disengaged, while in releasing it only the lower plate would require at-v tention.
Either of the two forms of clutch block illustrated will serve to bind together a pair of rods having their ends abutting, the block being brought to such a position that one of its clutch members will engage each of the rods.
I claim as my invention- A clutch-block comprising, in combination, a chambered box having a rod-recelvingaperture therethrough, a pair of clutch plates adapted to react-between the side walls of the box and the rod to which the block may be applied, and
a spring reacting between the plates to advanee them to theengaged position.
