SANFORD L. BUCKWALTER ATTORNEY.
STUD BOLT FULLER AND INSERTER This invention relates to stud bolt puller and inserters.
It is an object of the present invention to provide a simple and effective device for pulling of stud bolts from a stud block in which the engagement with the threaded portions of the stud bolt can be easily effected and wherein by a turning movement of one of the two members, the stud bolt can be lifted from the stud block by the reaction of the bottom end of one of the members with the top surface of the block.
It is another object of the invention to provide stud puller comprising a central spindle member and an outer sleeve member threadedly engaged with one another for complete axial movement of one member within the other wherein both members are provided with a wrench engaging surface to which a wrench can be applied to either one of the members for effecting the removal of the stud.
It is still another object of the invention to provide a stud puller which may also serve for the engaging of the stud within the stud block wherein the stud puller is so embedded or inserted within the central spindle member that hammer action upon the same will not disturb the threads but with this action be made fully upon the upper end of the stud.
Other objects of the invention are to provide a stud 1 puller and inserter having the above objects in mind which is of simple construction, has a minimum numer of parts, of pleasing appearance, adapted to be easily inserted upon the stud bolt, adapted to be easily removed from the stud bolt, durable, effective and efficient in operation.
For a better understanding of the invention, reference may be had to the following detailed description taken in connection with the accompanying drawing, in which:
FIG. 1 is a vertical elevational view of the stud bolt puller embodying the features of the present invention with portions broken away to show the interior construction and with the block into which the stud bolt is sunk being in section, both parts of the puller having their ends lying flush on the surface of the stud block.
FIG. 2 is a vertical elevational view of the stud puller with the inner threaded member lifted out of the outer member with the stud, the pulling operation having been finally effected.
FIG. 3 is an elevational view of the puller with the inner and outer threaded parts supporting the stud bolts preparatory to insertion by a driving action into a stud block, portions being broken away to show the interior construction of the puller and the hole in the block.
FIG. 4 is a further elevational view of the stud puller with the outer member having its ends lying flush on the block and with the inner member being worked to effect the backing off and pulling of thestud from the stud block, portions of the stud puller being broken away to show the interior construction thereof.
Referring now to the figures, generally indicates the stud bolt puller of the present invention. This puller comprises generally an elongated outer sleeve member 11 which is internally threaded its full height, the threads being indicated at 12. The exterior of the outer member 11 is of hexagonal cross section and adapted to accommodate a wrench head.
Workable within the outer hexagonal member and along the threads 12 is a central substantially equal height central member 13 having external threads 14 for substantially its full height and a squared top extension 15 for receiving a wrench open or box type. By turning the central member 13 one way or the other the same can be adjusted either downwardly or upwardly. The lower end of the central member has an upwardly extending threaded bore 16 adapted to accommodate threaded end 17 of a stud bolt 18 sunk into a smooth hole 19 to the extent of its smooth surface and in a block 21 adapted to accommodate such stud bolts.
In order to effect the insertion of the stud bolt 18 into the hole 19 of the block 21, the stud bolt is by its threaded portion 17 threaded into the bore 16 of the central member 13 and the parts 11 and 13 arranged generally as shown in FIG. 3 and upon the stud bolt being aligned with the opening 19 in the block 21 and by applying a hammer pressure as indicated by the arrow in FIG. 3 to the top of the assemblage the stud bolt will be driven into the block 21 in a tight fitting manner, the tolerances between the diameter of the stud bolt 18 and the diameter of the hole being such as to insure a tight gripping action, the diameter of the hole preferably being slightly less than the diameter of the stud bolt 18. Prior to the filing of the driving action the outer member can be backed off so that its lower end face is flush with the end face of the central member at the lower end thereof an as shown in FIG. 1. The stud bolt is made home as shown in FIG. 1 to the full depth within the opening 19 and upwardly to the threaded portion 17 of the stud bolt the lower end of which will lie flush with the top surface 22 of the block 21.
If the outer member 11 is turned as illustrated by the arrow in FIG. 1 while the central member 13 is held by a wrench engaging with the squared top extension 15, the stud bolt will as illustrated in FIG. 2 be backed off since the central threaded member will with the stud bolt be lifted as shown in FIG. 2. By continuing this action the lower end of the stud bolt will be made to clear the opening 19 and the surface 22 of the block 21. The engagement will have been made with the stud bolt 18 by first aligning the central threaded member 13 fully within the outer member 11 as shown in FIG. 1. Turning the unit in the direction of the arrow to thread the threaded bore 16 onto the threaded portion 17 of the stud bolt. A continuous movement of the outer member 11 in the direction of the arrow as shown in FIG. 1 and without holding the central member 13 will effect the lifting action as seen in FIG. 2.
The stud bolt puller can also be worked by holding the outer member and turning the central member as shown in FIG. 4. The central member will accordingly be lifted due to the upward threading action thereof within the outer member 11 so that the pulling of the stud bolt 18 is accordingly effected.
When the threaded portion of the stud bolt as indicated at 17 has been taken up by the bore threads 16 as shown in FIG. 1 the continuous turning of the outer member downwardly over the threads of the central member 13 will cause the lifting action and since the outer member cannot extend it downwardly into the surface 22 of the block, it must necessarily cause the central member to climb upwardly taking with it as shown in FIG. 2 the stud bolt 18. The threaded portion of the stud bolt can be of any length and the threading of the bore 16 of the central member 13 will automatically come to a stop at the end of the threaded portion by the smooth portion of the stud bolt 18. All of the threaded portions can be either right handed or left handed.-
It should be apparent that a backing off action is effected by holding one of the members while turning the other, either by turning the outer member without holding the central member or by turning the central member as illustrated in FIG. 4 while holding the outer member 1 1.
It should be apparent that an easy and quick method is afforded by the present puller to remove studs from a stud block. This puller tool simplifies the usual procedure for the removing of stud bolts and cuts the time for the removal of the stud bolts over the regular 7 methods.
Since stud bolts are approximately three thousandth of an inch over size in diameter for the stud hole in the block it makes pulling of the stud difficult with tools employing rocker arms and the like.
This puller tool can be used with a power wrench as well as with a hard wrench.
The square head of the central or spindle member 13 can be used for screwing the puller tool onto the threaded portion of the stud. The outer member 11 is then screwed onto the central spindle or stud to effect the lifting as described.
Once the stud has been inserted as shown in FIG. 2 by a driving action, the puller tool can be removed from the stud by turning the square head 15 of the central spindle 13. There should not be any damage of the threads on the stud if the stud is well threaded into the central bore of the central member or spindle 13 as shown in FIG. 3. The driving action would then be made upon the end of the stud bolt threads and without the transfer of the thrust through the threads. This puller tool takes up little space and should be readily available and handy for pulling the studs. The puller can be applied to the studs very easily either for the purpose of effecting the insertion of the stud or the pulling of the stud.
While various detailed changes may be made in the construction, it shall be understood that such changes will be within the spirit and scope of the present invention as defined by the appended claims.
