TOOL HOLDER.
Application filed March 27, 1925. Serial No. 18,690.,f
To all whom it may concern:
Be it known that I, FRANK PARDE'E, Jr.,
a citizen of the United States, and a resident of Hazleton, county of Luzerne, and
5 State of Pennsylvania, have invented certain new and useful Improvements in Tool Holders, of which the following is a specification.
This invention relates generally to tool holders and whilenot limited thereto aims to provide means for releasably locking a punch or similar tool in proper working position in its supporting member. Various embodiments of the invention are shown 1n the accompanying drawings.
Fig, 1 is a fragmentary elevation with parts shown in section illustrating a gang of punches releasably locked in their holder; Fig. 2 is an enlarged cross-section on line 2-2 of Fig. l; i
Fig. 3 is a magnified view' of portions shown in Fig. 2;
Figs. 4 and 5 are sectional details lllllS- trating alternative embodiments of the invention;
Fig. 6 is a horizontal section illustrating an alternative construction having certain advantages over the other devices 1llus trated;
Figs. 8, 9 and 10 are details illustrating various forms which the locking pm may take.
Referring in detail to the drawings, 10 represents the ram of a punch press which may be of any known type and reclprocated in the usual manner. 12 represents a platen or bed of such a press and 14 the work which is to be perforated.
In the embodiment of the invention illustrated, I preferably secure a tool holder 16 to the ram by means of bolts 18 or other equivalent securing means. The holder is formed with a plurality of tool sockets 20 adapted to receive the shanks 22 of the punches or other tools 24:. The upper sur-' face of the tool holder is grooved as at 26 for the reception of a hardened steel wear plate 28 which bears on the undersurface of the ram 10, this plate being adapted to transmit the thrust from the several punches directly to the ram; The shanks of the punches are'approximately the same diameter as the bore of the socket 20 only sufiicient clearance being allowed to permit I provide a locking pin 34 which is journalled in a substantially circular opening or bore 36 formed in the tool holder 16. This opening preferably extends at right angles to the axis of the tool socket 20 and intersects said socket. The locking pin 34 for'the greater portion of its length is cut away, for example, as indicated by the line 38 in Fig. 3, so as to form a locking portion of substantially semi-circular cross-section. As thus formed, it is apparent that by turning the pin on its axis the upper corner 40 can be caused to enter the notch 30 of the tool, thus preventing the same from, being withdrawn. The locking pin is provided with a handle 42 which as shown in Fig. 2 is adapted to project downwardly in a vertical line when the corner 40 is within the notch 30. This serves to indicate to the.
operator that the punches are locked. Furthermore, the weight of the handle tends to keep the locking pin in locked position. Reference to Fig. 3 will show that a portion 44 of the locking pin is ground oil to provide a slight clearance with respect to the arcuate face 32 of the notch in the punch. By so forming the parts the upper surface of the locking pin can be utilized to act as a cam to wedge or force the punch upwardly and thus firmly seat it in contact with the wear plate '28. Instead of entirely cutting away half of the locking pin as shown at 38 in Figs. 1 to 3 and 10 this lockin member may be cut away only at interva s indicated, for example, at 38' in Fig. 8 which spaces, of course, will be c posite to the punches to be locked. An a vantage of the type of lockin 'bar shown in Figs. 1. to 3 and 8 isthat t ere is no tendency to sheet the pin *on the downward "stroke of the .punch in the punch is not seated tightly striking the work and taking up. clearance between the top of the punch and the wear plate 28, will merely tend to rotate the locking pin in a direction tending to release the punch from the lock. Such movement will be indicated by the position of the handle 42 and will call the attention of the operator to the fact that some of the punches are loose.
In Fig. 4, I have shown an alternative embodiment of the invention including a plain cylindrical pin 46 located in a seat 36 formed in-the tool holder and adapted to engage a substantially semi-circular notch 30 formed in the punch shank 22.
In Fig. 5, I have shown a slightly modified arrangement in which the shank 22 of the punch is provided with an annular groove 31 with which the locking pin 48 is adapted to interfit. With this arrangement it will be understood that the punch can be turned relatively to its holder, whereas, in the forms previously described the locking pin will prevent such turning movement. In the forms of lock shown in Figs. 4 and 5, I may use either a plain cylindrical pin or if desired I can use a tapered pin as illustrated in Fig. 9. The tapered pin has the advantage that as the notch becomes enlarged due to wear the punch can be seated against the wear plate by merely tapping the pin so as to wedge the parts firmly 1n contact with one another.
The form of the invention shown in Fig. 6 is particularly well suited for use in gang punches. Such punches frequently are arranged in parallel rows. This figure shows .two such rows with the punches in one row staggered or offset with respect to those in the adjacent row. In such gang-punches, I propose to use a single locking pin to serve all of the punches in two separate rows. As shown in the drawing the tool holder 16 is formed with a transverse bore 50 which intersects the sockets 20 in which the several punches are seated. Each of the punches are formed with a notch such, for
example, as illustrated in Fig. 4 and a cylindrical portion of the locking pin 52 normally dwells within the. notch of each tool. The locking pin itself is provided with a number of notches indicated at 54, these being of substantially the same curvature as the periphery of the punch shanks 22. The spacing between the notches corresponds to the spacing between the punches ineach row. As thus arranged a slight endwise movement of the locking pin 52 will bring the notches thereof opposite the punch shanks and when they are so aligned, of 'course, the punches can be readily removed.
; holder for said Instead of releasing the punches by an endwise movement of the locking pin it will be a preciated that I can also release the punclies by turning the locking pin 180. Such turning movement will bring the notches of the locking pin into register with the punches and, therefore, permit their removal. For preventing accidental longitudinal movement or turning movement of the locking pin 52. I provide a set screw 54 threaded through a lug 55 of the punch holder which is adapted to be seated in depressions 56, 58 or 60 of the locking pin according to the setting desired.
Though I have described with great particularity the structure details of the various embodiments of the invention illustrated, it is not to be construed that I am limited thereto as various modifications and substitution of equivalents may be made by those skilled in the art without departing from the invention as defined in the appended claims.
What I claim is 1.v In combination with a notched tool, a holder therefor and a locking member arranged for engagement with the notch of said tool, said member having a portion of such cross-section that it will release the tool when turned relatively in said holder.
2. In combination with a notched tool, a holder therefor and locking means arranged for engagement with the notch of said tool and adapted to release the tool when turned relatively in said holder and to indicate whether or not the last named means is in looking engagement with the tool.
3. In combination with a notched tool', a holder therefor and a member normally locking the tool in place, said member having an interrupted portion which when the member is set at a predetermined position will permit theremoval of the tool from the holder.
4. In combination with a notched tool, a holder therefor and a. rotatably mounted locking member having a portion of noncircular crossvsection' adapted to be turned to a position to release the tool.
5.; In combination with anotched tool, a holder therefor and a locking member pivotall mounted in said holder and having a portion which when said member is turned Ill exerts a force tending to hold said tool rigidl in said holder.
6. a punch press, a multiplicity of notched punches arranged (punches, and a single looking pin mounte for coaction with at least one gang of punches. i
7. In a punch press, a multiplicity of notched punches arranged in gangs, a holder for said punches, and a single locking pin 111 gangs, 8-
