LOCKING MEANS FOR KEY-BOLTS.
Specification of Letters Patent.
Patented June 5, 1917.
Application filed Ap1 i125, 1916. Serial No. 98,514.
To all whom it may concern.
Be it known that I, F nnonnion L. H. SIMS, of the city of Toronto, in the county of York, Province of Ontario, Canada, a subject of the King of Great Britain, have invented certain. new and useful Improvements in Locking Means for Key-Bolts, of which the following is a specification.
This invention relates to key bolts of the type shown in my prior United States Patent No. 100M423 of August 15th, 1911, and my co-pending application No. 78%;) filed February 15th, 1916, and my object is to devise means for locking the wedge key in position in the slot in the bolt so that it can not drop out if for any reason it becomes loosened.
I attain my object by providing a strip of metal having an end adapted to be bent up to engage the outer end of the key and intermediate its ends shaped to engage either the bolt or a part through which the bolt passes, substantially as hereinafter de scribed and illustrated in the accompanying drawings in which Figure 1 is a vertical section through a rail and splice bars showing a key bolt in posit-ion provided with my improved lock;
Fig. 2 a horizontal section on the line a-b in Fig. 1;
Figs. 3 and 4, side elevations of modifica tions of the lock shown in Fig. 2; and
Fig. 5 a cross section through a key bolt showing another modification of the lock.
In the drawings like numerals of reference indicate corresponding parts in the dilferent figures.
1 isa rail, 2 the splice bars therefor; and 3 a slotted bolt of which 4 is the slot. The slot is usually sufficiently long so that it extends below the outer surface of the adjacent splice bar. 5 is the tapered key.
In its simplest and preferred form the lock 6 consists of a strip of metal bent intermediate its ends to form a shoulder 7, which may be engaged with the side of the hole in the splice bar through which the bolt passes. The end 8 of the lock is preferably beveled to make it convenient to force the edge of a cold chisel or other tool underneath it to bend the end up against the end of the key as shown. Preferably a second shoulder 9 is formed on the lock to engage the other side of the hole in the splice bar from the should r 7,- Th pr vent th 1 0k b i g pus d back todisengage the shoulder 7 when the end 8 is being turned up. The lock is, of course, easily inserted before the key is placed in position, and when the key is driven home tight and the end 8 turned up, the loosening of the key is strongly resisted, and if the key is loosened, the lock renders it impossible for the key to drop out and completely release the bolt.
If a greater thickness is desired in the lock, it may be obtained by doubling the metal of the lock upon itself as shown in Fig. 3, the end 8 being left projecting beyond the under part of the lock. In this form I show only a shoulder 7.
In Fig. 4: I show a lock of the same thickness as the lock shown in Fig. 3, but cut from a solid piece. In all three forms above described the shoulders on the lock engage the splice bar or other part through which the bolt passes. The lock will be just as effective, however, if the intermediate portion of the lock be adapted to engage the bolt itself, and a form adapted for this mode of operation is shown in Fig. 5, the projections 10 being formed on the side of the lock to engage each side of one-half of the bolt. The slot in the bolt is suiiiciently long to enable the lock to be put in edgewise and then turning down flat to the position shown.
hat I- claim as my invention is 1. The combination of an axially slotted bolt; a part through which said bolt passes; a removable one part key passing through the slot in the bolt; a locking strip passing through the slot in the bolt and lying be tween the key and the part through which the bolt passes, the said strip having an end bent u to engage an outer end of the key and intermediate of its ends being shaped to engage one of the parts relative to which the key is movable.
2. The combination of an axially slotted bolt; a part through which said bolt passes; a removable key passing through the slot in the bolt; a locking strip passing through the slot in the bolt and lying between the key and the part through which the bolt passes, the said strip having an end bent up to engage an outer end of the key and intermediate of its ends being shouldered to engage the part through which the bolt passes.
3. The combination of an axially slotted bolt; a part through which said bolt passes; a removable key passing through the slot in the bolt; a locking strip passing through the slot in the bolt and lying between the key and the part through which the bolt passes, the said strip having an end bent up to engage an outer end of the key and intermediate of its ends bent to form a shoulder to engage the part through which the bolt passes.
4. The combination of an axially slotted bolt; a part through which said bolt passes; a removable key passing through the slot in the bolt; a locking strip bent double and passing through the slot in the bolt and lying between the key and the part through which the bolt passes, the said strip having an end bent up to engage an outer end of the key and intermediate of its ends bent to form a shoulder to engage the part through which the bolt passes.
53. The combination of an axially slotted bolt; a part through which said bolt passes; a removable one part key passing through the slot in the bolt; a locking strip lying between the key and the part through which the bolt passes, the said strip having an end bent up to engage an outer end of the key and intermediate of its ends being shaped to engage one of the parts relative to which the key is movable.
6. The combination of an axially slotted bolt; a part through which said bolt passes;
a removable one-part key passing through the slot in the bolt; a locking strip passing through the slot in the bolt and lying between the key and the part through which the bolt passes, the said strip intermediate of its ends being shouldered to engage one of the parts relative to which the key is movable.
7. The combination of an axially slotted bolt; a part through which said bolt passes; I
