KEY.
Specification of Letters Patent.
Patented Apr. 3, ioi'a Application filed August 14, 1914-. Serial No. 856,796.
To all whom it may concern;
Be it known that I, FRANK J. DYETT, a citizen of the, United States, residing at Ilion, in the county of Herkimer and State of New York, have invented certain new and useful Improvements in Keys, of which the following is a specification, reference being had therein to the accompanying drawing.
This invention relates to certain new and. useful improvements in keys for holding or fastening members to shafts; the object being to provide a key which is exceedingly simple and cheap in construction and one which is so constructed that when the same is in position within its seat, all danger of it rocking is prevented, thereby the difficulties now existing with keys of this character in use being obviated.
Another object of the invention is to provide a key which is in the form of an oblong body having a substantially semi-cir- "cular lip which is adapted to be seated within a groove formed in the shaft; said body extending above the plane of the shaft into the groove of the member to be secured thereon.
Another object of the invention is to provide a key which is so constructed thatthe seat for the same in the shaft can be formed by a disk cutter, said cutter being of the same thickness as the thickness of the key so that a snug fit is formed, the oblong body preventing the lip of the key from extend- 3'5 ing into the shaft more than the desired distance; said body also forming a gage when the seat is being cut by the disk cutter, as by frequently inserting the key in the groove being cut, the proper depth can be obtained. Other and further objects and advantages of the invention will be hereinafter set forth and the novel features thereof defined by the appended claim.
I am aware that I am not the first in the art to provide a semi-circular key for looking amember to a shaft but in the prior patents covering this construction, no means was provided for limiting the movement of the keywhen in position within its seat, so"
as to prevent the same from rocking when the member is being inserted or removed from the shaft and it was impossible to obtain with prior constructions, the proper projection of the key from the periphery of the shaft, while with my construction, the body rests upon the periphery of the shaft adjacent each end of the seat so that the thickness of the body projects above the periphery of the shaft at all times and as the thickness of the body is known, the groove in the member to be mounted thereon, can be correspondingly cut whereby the insert1on of a member on a shaft is greatly facilitated.
In the drawings Figure 1, is a vertical section through a member, the shaft being partly broken away showlng myimproved construction of key inserted in position therein;
Fig. 2, is a section taken on the line 22 of Fig. 1;
Fig. 3, is an end view showing thelip of the key in dotted lines within the seat of the shaft;
Fig. 4:, is a perspective of the key, detached Fig. 5, is a vertical longitudinal section through a member showing the shaft in elevation with the key seated in position within a groove formed therein, having a greater depth than the width of the lip;
F1g. 6, is a side elevation of the shaft showmg the key way of insufficient depth to rece1ve the key in its proper position, the key being used as a gage for gaging the depth of the cut to be made;
Fig. 7, is a section through a member showing the key used as a gage for cutting the groove in the hub thereof; and
Flg. 8, is an elevation of the shaft and key in position showing a chisel being used for removing the key by forcing the same under one of the overhanging ends.
Llke numerals of reference refer to like parts in the several figures of the drawings.
In the drawing, 1 indicates a shaft, 2 a member to be secured thereon, such as a pulley or gear wheel, and while I have shown the member arranged adjacent the end of the shaft, it is, of course, understood that the same can be placed at any desired point and that the construction of the shaft and member has no material bearing upon the invention.
My improved construction of key comprises an oblong body 3 which is provided with a substantially semi-circular lip 4 and it will be seen that the lip has a length less than the length of the body whereby overhanging projections 5 are formed for the purpose hereinafter fully described.
In mounting a member upon a shaft with my improved construction of key, a disk cutter of the desired thickness, corresponding to the thickness of the lip of the key is employed to cut a substantially semicircular groove 6 in the shaft at the desired point into which the key is inserted with the body projecting above the periphery thereof and the lip into the groove 6, as clearly shown in Fig. 1. When this seat or groove 6 is being formed in the shaft, the key is inserted after each cut is made with the disk cutter so that when the groove is of such a depth that the overhanging projections 5 of the key rest upon the periphery of the shaft, the operator will know that the desired cut is obtained.
The hub of the-member 2 is then grooved longitudinally as shown at 7, the width of the groove ,being substantially the same as the Width of the body of the key and it will be seen that the same can be shoved into position upon the shaft without any danger of the key rocking, it of course, being understood that the same binding action obtained in keys is obtained between the Walls of the groove of the member and the sides of the body of the key, this being obtained by forming the grooves slightly narrower than the body of the key.
After the same has been wedged in position it will be securely held therein so that all danger of the same moving in any way, is prevented.
From the foregoing description, it will be seen that I have provided a key which when arranged within a seat of a shaft, will be prevented from moving in any direction, thereby overcoming the disadvantages now existing in semi-circular keys now in use.
I claim:
A key, comprising a substantially semicircular shaped lip having a body connected thereto formed with overhanging ends, said lips and body being of a uniform width.
In testimony whereof I aflix my signature in presence of two witnesses.
FRANK J. DYETT.
