UNITED STATES PATENT OFFICE.
ASSIGNOR TO FLANNERY BOLT COMPANY, OF PITTSBURGH, PENNSYLVANIA.
STAY-BOLT STRUCTURE.
Y Application led April 26, 1918. Serial No.. 230,910. Y
To all whom t may concern.' 1
Be it known that I, -ETHANI DoDDs, a citizen of the United States, and -aresident of Pittsburgh, in the county of Allegheny and State ofY Pennsylvania, haveV invented certain new and useful Improvements in Stay-Bolt Structures, and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to improvements in staybolt structures and more particularly to the closure for the bearing sleeve,-the object of the invention being to provide sim ple and ei'icient means whereby the cap or closure for the bearing sleeve shall be normally and firmly held to its seat but be permitted to be easily and quickly removed to expose the head of the staybolt for testing purposes. f
With this and other objects in view, the invention consists in certain novel features of construction and combinations of parte as hereinafter set forth and pointed out in the claims.
In the accompanying drawings; Figure 1 is a sectional View of a staybolt structure embodying my invention; Fig. 2A is a side elevation; Fig. 3 is a plan view, and Figs. 4, 5, 6 and 7 are views of modilications.
1 represents a bearing sleeve which may be externally threaded and provided interiorly with a curved surface 2 which serves as a bearing for the rounded or spherical head 3 of a staybolt 4. The outer end portion of the bearing sleeve is provided with a seat 5 for a cap or closure 6,-the latter having, in the construction shown in Figs. 1 to 3, an approximately hemispherical shape and its internal dimensions and coniiguration are such as to provide suitableclearance for the head of the bolt. l
A. collar 7 is threaded on the bearing sleeve and made with a hexagonal or other angular external configuration for the reception of a wrench.
The cap 6 is provided at diametrically opposite sides with pairs of perforated lugs or ears 8 and 9 and the collar 7 is provided with an outwardly projecting ear 10 to enter between the lugs 8. AV pin 8a passes through thelugs 8 and through a hole in the ear 10 whereby the cap will be pivotally attached or hinged to the collar,the holes specification of Letters Patent.
Patented Mar. 4, 1919.
in thelugs 8 or the hole in the ear 10 being appreciably larger indiameter than that of the hinge pin so as to provide a looseV connection.
A latch 11 has a loose connection with the `lugs 9 on' the cap by means of a pivot pin 12,-the hook end 13 of said latch being adapted to engage behind the collar 7 and the latter may be notched as at 14 to permit proper engagement of the latch with the collar.
When the parts shall have been assembled and placed in position on the bearing sleeve, as shown in Fig. 1, a further turning force applied to the collar by the application of a suitable wrench, will cause a slight -movement of said collar inwardly on the bearing sleeve and the cap 6 to be tightly clamped to its seat.
It will be apparent that when the collar 7 is turned in a direction reverse 'to that above described, the cap will be loosened and may be quickly removed to expose the head of the bolt for testing purposes. It is equally apparent that the cap may be as quickly replaced and clamped onto its seat at the outer end portion of the bearing sleeve.
In the form of the invention shown in Figs. 4 and 5, the cap is provided with a resilient latch 15 which is made integral with said cap, instead of employing a pivoted latch as shown in Figs. 1 and 3.
In the form of invention illustrated in Figs. 6 and 7, a plate cap 16 instead of a hemi-spherical cap is shown and provided on its top with perforated lugs 17, between 1. In a staybolt structure, the combina- Y tion with a bearing sleeve, and a collar threaded thereon, of a cap for closing said sleeve having pivotal connection with said collar, and alatch member projecting from said'cap and adapted to engage behind said collar. j
2. In a staybolt structure, the combina# tion With a bearing sleeve and a collar said sleeve, said cap having' pivotalE connec- 5 t1on with said collar, and a latch pivoted-to said Cap and adapted to engage behi'n'd'said Collane v '3. Inai st'ayboltstrueture, the combination with a bearing sleeve; off. aacapitoseati' ing; sleeve-'fand having; an;outil@arxdlgyaprojects:- 1ng'ear,rafvpivottpim looselyI connecting sard ear with the lug at one side of the cap, and a latch having4 la loose pivotal connection 15 andadapted to engage behind the threaded collar. f
I'n testimony whereof I have signed this speoioationlin the presence of two subscrib- 20 ing Witnesses.
