Definitions

  • the invention relates to a key cutting device as set out in the preamble of claims 1 and 3.
  • the starting point of the invention is represented by the document US-A-2731087.
  • the present invention relates to the code cutting type of device.
  • the automobile manufacturers have progressively reduced the thickness of automobile doors so that the available space for the lock assembly for the doors has been considerably reduced.
  • the lock manufacturers have accordingly found it necessary to reduce the length of the lock cartridge or mechanism.
  • the keys for these locks have been reduced in length and the customary uniform spacing between adjacent cuts on the key have also been reduced.
  • the cuts on existing keys are often shallower than has been standard practice in the art, and the first cut on many keys is so close to the shoulder of the key that a cut of less than standard width has to be made, otherwise the shoulder itself would be eliminated by the cut.
  • the shoulder of the key is necessary to precisely limit the extent of insertion of the key in the lock for proper operation, any mutilation or cutting away of the shoulder of the key must be avoided. Furthermore, in making replacement keys, the shoulder serves as the reference point for the cuts to be made on the key, so it is necessary that the shoulder not be damaged during the course of the cutting operation on a replacement key.
  • a conventional key blank 29, as used for the making of a replacement key, is suitably clamped or secured in a support member, generally indicated as 30.
  • the support member can be manipulated by greared knob 31 to move the key blank from side to side to various indexed positions for sequential cuts.
  • the support member is also vertically movable on the upstanding portion 23 to position it for a selected depth of cut.
  • the support member is provided with an adjustable notched depth gauge assembly 32 which can be manipulated to predetermine and preselect the depth of cut on the key blank at its different index positions of traversal.
  • a depth-gauging abutment or stop 33 is fixed to the upstanding portion 23 to limit the downward movement of the support member by engagement of the stop with a selected notch in the depth gauge assembly 32.
  • a pivotally mounted saddle element 34 has one end thereof operatively connected to the support member 30.
  • a stiff cantilever spring 35 has one end thereof affixed to the saddle element 34 and has its opposite free end yieldably engaging the camming surface 36 of the operating handle or lever 37 which is pivotally secured to the body 21.
  • the lever handle When the lever handle is retracted, it cams the free end of the cantilever spring 35 upwardly on one side of the saddle element, so as to cause the fixed end of the spring 35 to urge the opposite end of the saddle element downwardly and bring the support member downwardly therewith until the depth gauge stop 33 arrests its further downward movement.
  • a roller pin 38 is mounted through the spaced ears 39 on the free end of the spring to bear against the upper portion of the lever handle.
  • the punch 25 is provided with a circumferential projection in the form of a diametrically projecting pin 40 whose lower portion travels in a guide slot 41 which is provided in the body 21. This prevents angular rotation of the punch during its movements.
  • the pin 40 also serves as the seat for a coil spring 42 which surrounds a portion of the punch 25 and bears against the face of the portion 23 to cause retraction of the punch when the lever handle 37 is released.
  • the lever handle 37 is drawn toward the hand grip portion 43 to cam the end of the punch 25 and displace it forwardly in opposition to the coil spring 42.
  • the key blank 29 has already been laterally positioned by manipulation of the knob 31 for the first cut.
  • the elements of the depth gauge assembly have also been severally positioned for the various depths of cut required.
  • the camming surface 36 of the hand lever elevates the cantilever spring 35, which through the linkage of the saddle element 34, resiliently urges the support member 30 downwardly into abutment with the depth-gauge stop 33.
  • the tongue or guide portion 26 of the punch is always in the anvil opening .28, so that the punch is properly guided in its advance movement, until its cutting surface engages and penetrates the key blank 29 for the predetermined cut.
  • the lever handle 37 is then released and the coil spring 42 returns the handle and punch to their original positions, while at the same time the tension on the cantilever spring is relieved and the support member 30 is returned to its elevated position.
  • the knob 31 is again manipulated to index the key blank support member 30 to the second cut position and the key cutting operation is repeated. This cycle of operation continues until all the desired cuts are made.
  • the manual force applied to the hand lever 37 is transmitted, in a force- compounding action, to the punch which, in turn, translates this force into a pressure per unit area for shearing the desired portion of the key blank.
  • the punch 25 is provided rearwardly of the tongue 26 with a first step cutting portion 44 having a predetermined area of cutting surface 45.
  • This first cutting portion is smaller in cross-sectional area than the cutting area of a standard or conventional key cutting punch, as hereinafter more fully explained.
  • a second step cutting portion 46 Slightly rearward of the first cutting portion 44, is a second step cutting portion 46 having a cutting surface area 47.
  • the actual cutting area utilized in the cutting operation on the key blank will depend upon the depth of cut being made at any particular lateral index position of the key blank, so that these cutting surface areas have to be considered in terms of maximum areas for the deepest possible cut, even though less than the maximum remainder of the cuts, some locksmiths have resorted to ordering key blanks from the manufacturer which have the first cut already provided therein. This procedure requires the locksmith to maintain a large inventory of a variety of precut, first cut key blanks of different depths and shapes in order to render prompt service to replacement key customers. Furthermmore, the possibility of inaccuracies in the remaining standard cuts on the key blank still exists, even when a pre-cut key blank is used for the first cut.
  • the present invention is directed to overcoming both of the foregoing problems by improvements on key cutting devices of the type disclosed in the foregoing patents.
  • Another object of the invention is to overcome the above mentioned problems of the prior art key cutting devices by providing a code key cutter having locking means automatically responsive to actuation of the cutting punch for locking the key blank support member against punch-induced displacement from its preselected depth-of-cut position.
  • a key cutting device including a body, a longitudinally movable key cutting tool carried by said body, a key blank support member yieldably mounted on said body and selectively movable to bring a key blank into and out of the path of cutting movement of said key cutting tool, depth-of-cut gauging means carried by said body in the path of movement of said support member, and actuating means for effecting operative movement of said key cutting tool and said support member characterized in that said key cutting tool comprises a key shearing punch having a first cutting portion at its forward cutting end and an enlarged second cutting portion rearwardly of said first cutting portion, and adjustable punch-stop means carried by said body and selectively movable to arrest forward cutting movement of said punch before said enlarged second cutting portion (46) reaches operative cutting position.
  • the cited second object is achieved by:
  • Fig. 1 of the drawing there is shown a modified form of the key cutting machine which has heretofore been fully described and illustrated in my above-mentioned U.S. Patent No. 3,633,451.
  • the present description of the prior art structure shown will be abbreviated and reference made to said Patent No. 3,633,451 for a full description of the details of this form of prior art key cutting device.
  • the key cutting device or machine 20 includes a sturdy body 21 having longitudinally spaced upstanding portions 22, 23 and 24.
  • a key blank cutting tool in the form of a longitudinally-extending cylindrical shearing punch 25 slidably traverses the portions 23 and 24 and has a tongue or guide portion 26 which projects into the forward upstanding portion 22.
  • a hardened anvil piece 27 is mounted on the inward face of the portion 22 and is provided with an opening 28 40.
  • the slot 54 is of sufficient length to permit full stroke of the punch in the two-step operation described, so that both the cutting portions 44 and 46 of the punch would be permitted to act upon the key blank 29.
  • a recess 55 Adjacent one side of the slot 54, a recess 55 is formed and provided with a camming edge or surface 56 which leads back into the slot 54.
  • the recess 55 is off-set from the path of movement of the pin 40 when the stop element 49 is in its normal spring-biased position, so that the pin does not engage the recess.
  • the punch-stop element 49 is laterally displaced by a manual push on the flange 51, in opposition to the spring 53, the recess 55 is brought into the path of travel of the pin 40 on the punch 25.
  • this is accomplished by manual pressure on the flange 51 as the punch is actuated, so that the recess 55 will be moved into the path of movement of the pin as the pin travels initially through the longitudinal slot 54 and comes into a position adjacent the recess 55.
  • the pin then abuts the end of the recess and prevents further advancing movement of the punch to the end of its normal stroke.
  • This abutment of the pin in the recess 55 is predetermined to occur at a point in the stroke of the punch where the first cutting portion 44 has penetrated the key blank 29, but the second cutting portion 46 has yet not operatively engaged the key blank.
  • the pin 40 will retain the punch-stop element 49 in its punch arresting position.
  • the punch and the pin 40 retract and, in doing so, the pin displaces the element 49 back to its original position through coaction of the rearwardly moving pin 40 on the camming edge 56 of the element 49.
  • a spring return such as the described spring 53
  • biasing spring could be omitted.
  • the use of such a spring may be desirable to augment the mechanical camming displacement.
  • Fig. 9 shows a modified form of slot and recess arrangement for the punch-stop element 49.
  • both the longitudinal slot 57 and the abutment recess 58 are open-ended.
  • the recess 58 further differs from the previously described recess 55 in not being provided with a camming edge.
  • the punch-stop element of Fig. 9 functions in the same manner as previously described.
  • the slot 57 aligns with the pin 40 of the punch during full stroke movement of the punch.
  • the recess 58 becomes aligned with the path of movement of the pin 40 and limits the stroke of the punch to the desired first step cutting position only.
  • FIG. 10 another modified form of slot arrangement for the punch-stop element is shown.
  • an open ended longitudinal slot 59 is provided for full stroke operation of the punch 25.
  • the punch-stop element is laterally displaced by pressure on the flange 51, the rearward edge 60 of the punch-stop element is disposed in the path of movement of the pin 40 which abuts that edge, thereby limiting the stroke of the punch to the operation of the first cutting portion 44 only.
  • a return biasing spring 53 is utilized to retract the element to its normal position after the cut has been made.
  • the forms of Fig. 9 and Fig. 10 have the advantage of permitting the punch-stop element to be laterally pushed into stroke-limiting position before the punch 25 is actuated, whereas in the form shown in Figs. 7 and 8, there has to be some forward movement of the pin 40 before the punch-stop element can be pushed into stroke-limiting position.
  • FIG. 11 of the drawing there is shown another form of punch-stop arrangement 61 which utilizes a spring-biased pin 62 which is mounted for slidable movement in the side of the body 21 of the key cutting device.
  • pin 62 When the pin is depressed, it is projected into the path of movement of the lever handle 37 to correspondingly limit the stroke of the punch 25 to a position where only the first cutting portion 44 will act upon the key blank 29.
  • the pin 62 is not so depressed to traverse the body 21, it remains out of the path of movement of the lever handle 37, thus permitting full stroke two-step operation of the punch.
  • locking means 63 for automatically locking the key blank support member 30 against punch-induced displacement from the depth-gauge stop 33 during the cutting action.
  • the locking means consists of a saddle element 64 having spaced dependent ears 65 which are surmounted by spaced edge cams 66.
  • the saddle element is provided with a body portion 67 in which is threadedly secured an adjustable abutment pin 68.
  • the saddle element 64 is pivotally mounted upon the ends of the previously described roller pin 38 so that the edge cams 66 straddle the end of the cantilever spring 35 and the body 67 extends rearwardly thereof so as to bring the pin 68 into abutment with the camming surface 36 of the lever handle 37.
  • a torsion spring 69 encircles. the roller pin 38 and has its ends disposed to resiliently maintain the pin 68 in abutment with the camming surface 36 during the initial actuating movement of the lever handle 37.
  • the locking device 63 is also displaced upwardly and is caused to rotate about the roller pin axis 38 by spring 69 to bring the edge cams 66 into locking abutment with the cutting areas will frequently be utilized for shallower cuts.
  • the cutting surface areas 45 and 47 are considered in terms of their maximum depth of cut areas or whether they are considered in terms of their effective cutting areas at some shallower cut, the relationships between them, as hereinafter described, will hold true.
  • the combined areas of the cutting surfaces 45 and 47 can be considered as the equivalent of the cutting surface area of a standard or conventional punch, i.e. the cutting surface area that would exist on the punch 25 if the first cutting portion 44 did not exist and the entire cutting surface was presented by an unobstructed cutting portion 46.
  • the area of the cutting surface 45 is less than the combined area of the surfaces 45 and 47, but is a greater area than the cutting surface 47 of the second step cutting portion 46. This relationship between the cutting surfaces presents distinct advantages in the cutting operation.
  • first portion 44 By utilizing a first cutting portion of smaller than standard cutting area, that first portion 44 can provide a closer center line-to-center line cut than could a standard size punch. Furthermore, by making this reduced cutting area asymmetrical, rather than symmetrical as is standard practice in the art, the first cutting portion 44 can make the first cut on the key blank closely adjacent the shoulder of the key blank without mutilating or cutting away any portion of that shoulder. At the same time, by utilizing the two-step punch operation which will be described, the standard form of cut with standard lateral center line spacing can still be made in the key blank with the same punch, as required.
  • a two-step shearing or punching sequence is effected.
  • the punch is first advanced for penetration of the key blank by the first cutting portion 44.
  • the entire compound force applied through the lever handle 37 is concentrated onto the small area of the cutting surface 45, so that a greater shearing or cutting pressure per unit area is applied to the key blank than would be the case if the larger cutting area of a conventional punch structure were used. Thereby, the force required for the initial shearing or cutting action on the key is reduced.
  • the two-step structure of the punch 25 also permits a flexibility of cutting operation which cannot be accomplished by a single step cutting punch structure.
  • Fig. 5 there is schematically illustrated a track made by the first cutting portion 44 of the punch 25 as it advances through the key blank 29.
  • the shoulder 48 of the key blank is shown adjacent the punch portion 44, so that Fig. 5 represents the first cut on the key. It will be noted that this cut is accomplished without cutting away any part of the shoulder 48.
  • the trailing second cutting portion 46 showing its outline, it will be apparent that a standard punch structure would have cut through the shoulder 48.
  • Fig. 6 sehcmatically illustrates a second or later cut of conventional form in the key blank 29.
  • the initial cut was made by the first cutting portion 44, but as the punch 25 was advanced in the two-step operation, the second cutting portion 46 completed the cut by removal of key metal which had not been removed by the first cutting portion 44.
  • the schematic illustrations of Fig. 5 and of Fig. 6 are representative of a single depth of cut, and that the support member 30 could position the key blank 29 for a shallower or deeper cut, as required.
  • an adjustable punch-stop means for arresting the cutting movement of the punch 25 and limiting its stroke so that only the first cutting portion 44 of the punch is utilized in making the desired cut.
  • FIG. 7-8 there is shown a somewhat U-shaped punch-stop element 49 having a central body portion 50 and downwardly depending, oppositely disposed flange portions 51 and 52.
  • the central portion 50 rests on the flat upper surface of the body 21 of the key cutting device.
  • the flanges 51 and 52 straddle the body 21 and limit lateral movement of the punch-stop 49 relative to the body 21.
  • the central portion 50 sits slidably between the spaced upstanding portions 23 and 24 of the body 21, so that little or no longitudinal displacement of the element 49 is permitted.
  • a portion 53 of the larger flange 51 can be slit and bent toward the body 21 to form an integral leaf spring which will bear against the side of the body 21 and resiliently urge the punch-stop element to a lateral position where the flange 52 abuts the opposite side of the body 21.
