RODNEY V. NORTHEY, F TORONTO, ONTARIO, CANADA, ASSIGNOR TO JOHN P. NORTI-IEY, TRUSTEE, OF TORONTO, CANADA.
GIB.
Application filed February 25, 1925.
To all whom. a may concern:
Be it known that I, RODNEY V. NORTHEY, of the city of Toronto, in the county of York, Province of Ontario, Canada, a subject of the King of Great Britain. have in-- vented certain new and useful Improvements in Gibs, of which the following is a specification.
This invention relates to gibs particularly adapted for use with a key bolt, that is, a bolt having its stem slotted for the passage of a wedge-key which takes the place of a nut. Such bolts are not ordinarily well adapted for use where much draft is required, as this necessitates either the use of a very long key or a key of steep pitch, and either alternative is objectionable. My object therefore is to devise a gib, which, when used with a key of a given length and pitch, will give a much greater range of draft.
I attain my object by forming the gib with a longitudinal key engaging edge, and a plurality of seats opposite said edge, and 25 at different distances therefrom, adapted to engage the end of the slot in the bolt substantially as hereinafter more speeifi-- cally described and illustrated in the accompanying drawings in which Fig. 1 is a side elevation of my improved gib used in connection with a key bolt, which is shown in section;
Fig. 2 a similar view showing the gib in its second position;
Fig. 3 a side elevation of a modified form of the gib; and
Fig. 4 a similar view of another modification.
In the drawings like numerals of reference indicate corresponding parts in the different figures.
1 is a bolt formed with a slot 2, and 3 is a wedge key. A gib 4 is provided with a straight edge 5 adapted for engagement by the wedge key. The opposite edge of the gib is provided with a plurality of seats 6 at different distances from the edge 5 of the gib. In Figures 1 and 2 these seats are shown as substantially straight and parallel to one another and at an angle of about 7 to the edge 5 of the gib. Shoulders 7 and 8 are thus formed on the gib.
In Fig. 13 the slope of the edge 5 relative .to the seats .6 is reversed, while in Fig. 4:
Serial No. 11,478.
the seats are formed'as depressions in the slope of the edge 9 opposite the edge 5.
Particularly in driving ship plates, con siderable draft is needed in the temporary bolts employed, the plates in the first place being frequently separated as shown in Fig. 1. In using my gib in the drawing up of such plates, the bolt is inserted and the gib positioned as shown in Fig. l. The key is then driven as far as possible. The plates are thus partly drawn together and the gib and wedge are then driven out and the gib positioned as shown in Fig. 2. lVith the end of the slot in engagement with the seat on the gib, which is farthest from the edge 5, the wedge key is then again driven in until the plates are drawn tightly to gether. It will be noted that the shoulders 7 and 8 prevent the gib from being displaced as the key is driven.
The seats are preferably rounded transversely as the end of the slot is also rounded transversely.
The gib shown in Fig. 3 is used in exactly the same way as the gib shown in Figs. 1 and 2, with the exception that the movement in shifting it to its firstv and second position is in the reverse direction from that in shifting the gib shown in Figs. 1 and 2.
The form shown in Fig. 4 is essentially that shown in Figs. 1 and 2, with the exception that the seats are shaped to fit the end of the slot in the bolt. Particularly when keybolts are made as shown and described in Canadian application No. 278,83 l filed July 12th, 1923, the end of the key slot tends to become conveXly curved in the direction of the depth of the slot, and I find it is important to concavely curve the.
\Vhile my gib is particularly adapted for use with the bolts used in drawing up ship plates, it Will also be found useful for rail bolts and for other purposes.
hat I claim is:
1. A slotted bolt and Wedge key in combination With a gib having a longitudinal key engaging edge inclined to the axis of the bolt and a plurality of seats opposite said edge, and at different distances therefrom, adapted to engage the end of the slot in the bolt.
2. A slotted bolt and wedge key in C0111- bination with a gib having a longitudinal key engaging edge inclined to the axis of the bolt and having the opposite ed e stepped to provide a plurality of seats opposite the key engaging edge, and at different distances therefrom, adapted to engage the end of the slot in the bolt.
3. A slotted bolt and wedge key in cornbinat-ion With a gib having a longitudinal key engaging edge inclined to the axis of the bolt and having a plurality of substantially parallel surfaces in stepped relatioir ship, arranged opposite and at an angle to the aforesaid edge.
4:. A slotted bolt and Wedge key in combination With a gib having a longitudinal key engaging edge inclined to the axis of the bolt and a plurality of seats opposite said edge, and at different distances there from, adapted to engage the end of the slot in the bolt, the end of the slot being concave transversely and the seats correspondingly convexed.
5. A slotted bolt and Wedge key in combination with a gib having a longitudinal key engaging edge inclined to the axis of the bolt and a plurality of seats opposite said edge, and at different distances therefrom, adapted to engage the end of the slot in the bolt, the end of the slot being concave transversely and convex in the direction of the depth of the slot and the seats correspondingly shaped to fit said end.
(3. A slotted bolt and Wedge key in C0111- bination with a gib having a longitudinal key engaging edge inclined to the axis of the bolt and having the opposite edge stepped to provide a plurality of seats opposite the key engaging edge, and at different distances therefrom, adapted to engage the end of the slot in the bolt, the end of the slot being concave transversely and the seats correspondingly convened.
7. A slotted bolt and wedge key in combination with a gib having a longitudinal key engaging edge inclined to the axis of the bolt and having the opposite edge stepped to provide a plurality of seats oppo site the key engaging edge, and at different distances therefrom, adapted to engage the end of the slot in the bolt, the end of the slot being concave transversely and convex in the direction of the depth of the slot and the seats correspondingly shaped to fit said end.
Signed at Toronto, Canada, this 12 day of February, 1925.
RODNEY V. NORTHEY.
