BOLT-LOCK.
Specification of Reissued Letters Patent. issued Dec, 13, 1921 Original No. 1,346,907, dated July 20, 1920, Serial No. 271,589, fil-ed January 17, 1919. Application for reissue 1ed December 24, 1920. Serial No. 433,055.
To all whom 'it may concern.'
Be it known that I, SWENEY MUNsoN, a citizen of the United States, residing at Scammon, in the county of Cherokee `and State of Kansas, .have invented certain new and useful Improvements in Bolt-Locks, ot which the following is a specification.
My invention relates to improvements in bolt-locks.
It is particularly adapted for locking tap bolts to hold them from turning. and .is adapted'for use in connection with a bolt having 'a head.
My invention provides a locking member Which is adapted to embrace the bolt, head and to engage a portion :formed with and offset from the surface of the .member against which the bolt headbears to" hold said bolt fromv rotation. My invention further provides means-associat'ed with thelocking member for holding said'locking meniperir'om longitudinalmovement on'the bolt lea',
My invention is particularly well adapted for use in connection with devices embodyin two members, through one of which the bo t extends and with the other of which members the bolt has screw-threaded engagement.
The novel features of my invention are hereinafter fully described and claimed.
, In the accompanying drawing, which illustrates my invention,
Figure 1 is a plan view of my invention shown 'applied to an ordinary shaft bearing.
Fig. 2 is a vertical sectional view on the line 2-2 of Fig. 1.
Fig. 3 is a vertical sectional View of a rail joint provided with my improvement.
Fig. 4 is a perspective view of a hexagonal collar adapted for use in connection with the bolts which have hexagonal heads.
Fig. 5 is a perspective view of a square collar adapted for use on a square headed bolt, such as is shown in Fig. 3.
Fig. 6 is a fragmentary side elevation of Fi .3. i imilar reference characters designate similar parts in the different views.
Reierringrst to Figs. 1 and 2, 1 designates the cap and 2 the base of an ordinary box or shaft bearing. 3 designates the screw-threaded shank oi an ordinary ta bolt, one of which is employed at each si e 5b of the bearing. Each tap bolt has its threaded shank engaging threaded openings in the parts 1 and 2. Each bolt is formed with a preferably fixed head 4, of hexagonal or other suitable Jform, which bears against the plane,wholly superficial upper abutment surface 4 of the cap 1'. Fitted on the head 4 is'a collar 5, of hexagonal or other suitable angular .orm, a portion or one of the sides of which is disposedv between the bolt head and a shoulder, raised portion or like surface G'fformed on the cap 1 'and projected beyond the 'plane of the said wholly supericalabutrnent surface 4. Such portion or side' of the'collar 5, lying between the head 4 and surface 6, is arranged for contact with the latter so as to hold-the collar from turning, thereby holding the bolt on which the collar is fitted from turning. Suitable means are'provided Jfor holding` the vcoll'ar' fromlongitudinal movement on and from slipping off from the bolt head 4. In Figs.' 1 and'2, Il have shown each bolt headl4' provided with one 'or more' transverse holes 7, 'through one of which maybe ex tended a suitable locking pin, "such as a cotter pin 8, which may also be extended through the adjacentcollar 5.
In the operation of m invention, as shown in Figs. 1 and 2, the bolts 3 are extended through the cap 1 and screwed into the base 2 so as to have the heads 4 bear tightly against the upper abutment surface of the cap 1. The bolts are turned until one side of each bolt is disposed parallel with the adjacent shoulder 6. The collars 5 are then slipped onto the bolt head4respectively, the thickness of the collar being such as will permit it to slip between the bolt head and the adjacent shoulder 6 and such as will cause it to contact with the shoulder 6 so as to hold the collar from turning. The Cotter pins 8 are then extended respectively through the collars 5 and the adjacent bolt heads 4.
In the form of my invention shown .in Fig. 3, 9 and 10 designate respectively two angle plates, between which is clamped a rail, in the manner usual in rail joints.
12 designates the screw-threaded shank oi a bolt which extends horizontally through the angle plates 9 and 10 and the web of the vrail 11, the threaded end of the bolt being' fitted in the screw-threaded hole provided in the angle plate 10.
The head 13 of the bolt 12 is square or of other suitable form and bears against the outer Wholly superlicial plane abutment face or side 13 of the angle plate 9. The latter is provided with aportion projected beyond the plane of said abutment face and com prising a longitudinal flange 14 which. bears in the usual manner upon the aeent upper side of the base of the rail. Fitted on the square head 13 ofthe bolt is a locking meinber, preferably comprising apeollar 15 `having a beveled side 16 ivhieh bears against the `flange 1li and holds the collar from turning relatively to the angle plate 9. The cellar 15 thus holds the bolt iroin turning.
The head 13 of the bolt is provided with one or more transverse holes 17, through one of which and through the collar 15 4entends a suitable locking device, such as a eotterA pin 18. The cotter pin 18 holds the collar 15 from longitudinal movement on they head 13. i
The angle plates 9 and 10 having been clamped in the usual mannerto the rail 11 by the bolt 12, the collar 15 is slipped onto the head 13 of the bolt, with the beveled edge 16 of the collar resting against the flange 14. The cotter pin 18 is then extended through-the collar 15 and bolt head 13, in which* position it is held in the usual manner by having its ends bent laterally in :opposite directions at the outer side of vthe collar.
It Will be noted that the collars 5 and 15 embrace only the sides of the head o the bolt. This permits the employment ei a bolt having any length of head Without changing angle plate, of a bolt extending through one flange oi' said plate and having a head other than circular bearing against said flange, a collar embracing and iitted to the sides only of said bolt head and at one side having a bearing against the other flange ofvsaicl plate, the other side of the collar being Clear of said plate, and a pin insertible through and re movable from the collar and the head o said bolt While the collar is in the locked positiomsubstantially as set forth.
2. A lock device for a'fastener having a .f
.head provided With radial intersecting transverse openings, comprising a collar like elenient shaped to peripherally embrace said head When projected beyond a piece of Work ing surface and When applied thereto adapted to laterally abut an adjacent part of the suri face secured by the fastener to prevent turning othe head, and means positively engaged in the collar and any one of the open ings in the head to prevent displacement of said collar and head relative to each other.
in testimony whereof l ailixmy signature.
