SHAFT-LGGKING DEVICE.
Specification of Letters Patent.
Patented Jan. 25, 1316.
Application filed November 3, 1914. Serial No. 870,978
To all whom it may concern Be it known that T, Jenn BOYLE, Jr., a citizen of the United States, and a resident of Paterson, in the county of Passaic and State of New Jersey, have invented a new and useful improvement in Shaft-Locking Devices, of which the following is a specification.
My invention relates to a shaft locking device for general use where a pinion or other element is to be caused to rotate with the shaft while being allowed to slide thereon.
Tn the accompanying drawings, Figure l is a view in elevation showing a pinion loclted to the shaft, Fig. 2 is longitudinal central section, Fig. 3 is a view in elevation showing the pinion moved along the shaft in a position to release the locking element and the locking element removed from its seat. Fig. i is a transverse section in the plane of the line A-A of Fig. 1, and Fig. 5 is an end view of the locking element.
The shaft is denoted by 1 and the pinion by 2. The locking element has a base portion 3 in the form of a segment of a cylinder and a tongue piece 4- projecting from the base 3 and also having the form of a segment of a cylinder of less diameter than the diameter of the cylinder of which the base 3 is a segment. The tongue extension 4 is, in practice, intended to be the segment of a cylinder having a diameter corresponding to the diameter of the shaft 1, while the cylinder of which the base 3 of the locking element is a segment conveniently has a diameter corresponding to the diameter of the hub 5 of the pinion 2.
To receive the locking element, the shaft 1 is provided with a recess 6, see Fig. 3, having a length corresponding to the length of the locking element, base and tongue combined, and a depth corresponding to the depth of the tongue extension 4. The recess 6 has a plane surface for its bottom, said surface being parallel with the axis of the shaft, and the two ends of the said recess 6 are in planes at right angles to the longitudinal axis of the shaft, so that when the locking element is seated in the recess 6, its fiat side will rest on and conform in size and shape to the base of the recess 6, while the curved surface of its tongue extension 4 will form a fair continuation of the cylindrical surface of the shaft 1.
The hub 5 of the pinion 2 has a portion of its end cut away forming a notch 7, see
3, said notch 7 having a depth measured in a plane at right angles to the central axis of the pinion equal to the depth of the base 3 of the locking element; that is, equal to the thickness of the wall of the hub plus the depth of the tongue extension 4;, and the length of said notch 7 measured in a plane parallel with the longitudinal axis of the pinion is equal to the length of the base 3 of the locking element; that is, when the locking element is seated in the recess 6 and the pinion is slid over the tongue portion of the locking element, the base portion 3 of the locking element will exactly fill the notch 7 in the hub of the pinion, so that the fair cylindrical contour of the hub will be continued by the curved'surface of the base 3 of the locking element.
To assemble the parts, the locking element is placed in its recess 6 and the pinion slid over it in such rotary adjustment as to cause the base 3 to seat in the notch 7 of the hub 5 of the pinion, as clearly shown in Fig. 2.
It will be noted that in forming the elements to be locked together and the element which does the locking, the three elements are cut away or reduced in a single transverse plane, viz: in a transverse plane passing along the face of the end of the base portion of the locking element from which the tongue projects, see Fig. 3, and furthermore, that the three elements meet in a single plane parallel to the axis of the shaft and nearer the said axis than the length of a radius of the shaft.
This structure has the advantage of simplicity in that the shaft may have the recess formed therein without any gouging process as in the ordinary form of the feather and groove, and the hub of the pinion or other element to be locked to the shaft may in like manner be out without the use of any grooving tool, and furthermore, when the parts are seated and assembled, the locking element will have an extended transverse base to hold it against a rotary movement with the shaft while the hub of the pinion or other element will have an extended engagement with the locking element to insure it against any liability of shearing whatever he the strain.
The structure affords perfect balance which is favorable to high speed; a perfectly smooth exterior which favors safety; no set screws which favors dependability and no projecting shoulders on the shaft which cheapens and simplifies construction. Furthermore, the parts may be assembled and separated in a very simple and expeditious manner.
lVhat I claim is:
l. The combination with a shaft provided surface of the shaft for engaging an element carried by the shaft.
2. The combination with a shaft having a recess on 1ts exterlor, sa1d recesshavmg the formofthesegment of'a-cylin'der and an element fitted to slide on the shaft and provided With a notchin the end of its hub, said notch having the shape of the segment of a cylinder, of a locking element fitted to seat in the recess in the shaft, one portion of said locking element having across section correspondingto the cross section of the recess in the shaft and another portion constructed to fit thenotch inrthe hub of the said element carried by the shaft.
Intestimony, that I claim' the foregoing as my invention, I have signed my name in presence: of tWo Witnesses,v this thirty-first day of. October 1914:. p
