STUD DRIVER.
Application filed June 20, 1923. Serial No. 846,829.
T 0 all whom it may concern Be it known that I, Lewis SKEEL, a citizen of the United Sta es, and resident of Meadville, in the county of Crawford and State of Pennsylvania, have invented certain new and useful Improvements in Stud Drivers, of which the following is a specification.
This invention relates to stud setters especially adapted for use in driving studs into castings and the like.
An important object of this invention is to provide a stud setter having simple means whereby the drivin connection between the same and the stu may be established or broken without stopping or reversing the machine-to which the stud setter is attached.
Afurther object is to provide a stud driver wherein the lateral thrust on the gripping jaws when the stud bottoms or is driven home is utilized to assist thebreaking of the driving connection between the stud driver and the stud.
A further and equally important object is to providea stud driver having simple means whereby the gripping jaws may be instantly I removed and aws of another size substiituted, all withoutv removing bolts or other fastening devices and without the aid oftools.
Also the invention forming the subject matter of this application aims to provide a stud driver which is characterized by its extreme simplicity, durability and cheapness of manufacture.
Other objects and advantages will be apparent during thecourse of the following I description.
In the accompanying drawings forming a par-t of this application and in which like numerals are employed to designate like parts throughout the same,

In the drawing wherein for the purpose of illustration is shown a preferred embodiment of the invention the numeral 5 generally designates a friction drive member of any suitabletypeand by reference to Figures 2and 3 it will be seen that the forward provided with longitudinal semi-circular.
grooves8 which cooperate in the formation of a socket for the reception of a stud 9. Of coursethe walls of the semi-circular grooves 8 are threaded for engagementwith the threads of the stud so that a positive driving'connection is provided between the jaws and the stud. Y
Figure 4 clearly illustratesthat the for ward portions of the'jaws are provided with transversely inclined fiat faces 10 and'll, the faces 10 being en aged with the flattened wall 12 of the soc et when the. jaws are in their advanced or stud receiving positions. When the jaws are in their operative or stud gripping position as illustrated in Figure 2, the faces 11 are flatly in engagement with the faces 12 whereby a positive driving connection is provided between the driving member and the jaws. As the faces 10 are.
flatly in engagement with the faces 12 when the jaws are in their inoperative positions the jaws are caused to rotate with the driving member so that the jaws are always in a position to freely enter the socketas illustrated in Figure 2. It might be said that a constant driving connection is provided hetweenthe jaws and the driving member regardless of the positions of the jaws.
Transversely inclined shoulders .14 I are formed on the outer sides of the jaws 7, between the faces 10 and 11 and as the jaws are being moved rearwardly by a means to be described the inclined shoulders will contact with the driving faces 12 and thereby move thejaws inwardly or together. When the shoulders 14 pass the inclined faces 12 the driving faces 11 will be flatly presented to the driving faces 12, so that. the jaws are moved closer-together. It will be seen with I The slight transverse inclination of the driving faces 11 and 12 prevents binding between the jaws and the driving members as the result of the lateral pressure exerted by the stud when the latter is bottomed or is driven home. In explaining this point it might be stated that when the stud 1s bottomed or when it reached home there is a strong tendency of the threads onthe jaws would prevent the release of the jaws from.
the driving member.
The socket in the driving member is formed adjacent its rear end with an annular inclined shoulder 16 arranged in the path of travel of the several contact portions 17 of the shanks 18 of the jaws, the said shanks being semi-cylindrical. In use the beveled portions 17 will contact with the shoulders 16 simultaneously with the .en-
. gagement of the shoulder 14 with the driving faces 12 so that both ends of the jaws will be moved inwardly together. When the beveled portions 17 pass the shoulder 16 they will enter the reducedrea-r end of the socket and flatly contact with the inclined side wall 20 of the reduced rear portion of the socket. By inclining the portions 17 and 20 the rear portions of the jaws are prevented from binding as a result of the lateral pressure resulting from the bottoming of the stud.
Figures 2 and 4 clearly illustrate that a contact head 24 of cylindrical formation is arranged in the rear portions of the groove 8 and is mounted upon the intermediate portion of a jaw connecting pin 25. The terminal portions of the pins 24 are enlarged as indicated at 26 to provide disk-shaped stop elements located in recesses 27 in the outer faces of the shanks 18. By this means the separation of the jaws is limited and the movement of one jaw longitudinally with respect to the other jaw is prevented.
It will be observed that the rear end of the contacthead 24 is flatly in contact with the rear ends of the grooves 8 so that the end thrust on the head 24 is not borne by the pin 25;
The jaws are urged to their stud receiving positions by gravity and by springs 30 received in sockets in the opposite sides of the jaws and of course when a stud is introduced into the socket formed by the jaws the jaws will be moved rearwardly'and together against the tension of the springs 30.
In operation jaws of a desired size are inserted into the socket in the forward end of the friction driving member 5 and a stud is subsequently introduced into the socket formed by the jaws. The engagement of the stud with the head 24- will move the jaws rearwardly so that the inclined portions 17 will contact with the shoulder 16 simultaneously with the engagement of the straight shoulder 14 with the driving faces 12 wherebyth'e threads on the inner sides of the jaws are engaged with'the threads on the stud. The subsequent rotation of the driving member v results in driving home or bottoming the stud and when the resistance is increased beyond a predetermined point the driving member will slip. The driving member is now withdrawn or moved 'rearwardly without stopping the machine and without reversing andthe jaws will by their engagement with the threads on the stud be returned to the position illustrated in Figure 3. The inclined contact faces 17, 20 and 11 and 12 will effectively prevent binding of the parts.
The rounded shanks 18 are extended beyond the straight faces 10 to define shoulders 36 which rest upon a pair of parallel stop shoulders 37 in the forward portion of the socket in the driving member. Figure 2 illustrates that the forward portion of the socket in the driving member is formed with an annular groove 38, the lower wall of which is extended inwardly beyond the upper wall thereof to define the stop shoulders 37 arranged in the path of travel of the shoulders 36. In use the loss of any of the parts is absolutely prevented due to the stop shoulders 36 and 37. However when it is desired to detach the jaws for substitution of jaws of another size the jaws are merely pressed together by ones hand so that the shoulders 36 will clear the shoulders 37. Of course the removal of the jaws 7 will also accomplish the removal of the head 24, the pin 25 and spring 30 so that a new set of jaws and associated elements may be quickly inserted.
One of the principal features of the invention resides in the quick releasing means by which the tool may be disconnected from the stud when the stud has been driven home or bottomed. It will also be seen in summarizing that the direct drive between the driving member and the jaws greatly reduces the number of parts necessary.
Furthermore the fact that the tool may continue to rotate in the same direction during the disconnection of the stud therefrom adds greatly to the desirability of the invention.
