PATENT oFFlcE.
AUGUST BIONDI,` 0F .ALLENTOWN, PENNSYLVANIA.
Application inea Aprn '2,
To all whom t may conce/'11,.' y.
Be it known that I, AUGUST BIONDI, a citizen ofthe United States, residing at Allentown, in the county of Lehigh` vand State of Pennsylvania, have invented new and useful Improvements in Key-Cutting Machines, of which the'following is a specification. j s Y This invention relates to key cutting or milling machines, and the principal obj ect is v to produce a device of this nature which may be utilized for cutting keys having sloping notches as well as'keys having abrupt or` square notches, withoutfhaving to "insert different cutters in the machine.` j
Another object is to produce, a device of this nature in which an automatic feed may be had for feeding the key blank vto the cut# ter synchronously with the operation of the cutter.
Another object is to provide a machine of this class with tensioning means which may berendered effective and ineffective at the will of the operator.
Another object is to produce a deviceJ of this nature which vshall be 'simple "of con` struction, cheap to manufacture, and` highly efiicient for the purpose for which' it is designed.`
With these and otherobjects in view as will bemore apparent, the invention consists in certain novel construction. and combinatiouand arrangement of parts,'the'essen tial features of which are hereinafter' fully described, are particularly pointed out in the appended claims, and are illustrated in the accompanying drawing, .in which Figure lis a top plan view of my improved key iiling machine.
Figure 2 is an end elevation of the same.
Figure 3 is a section" on line 3-3 of Figure 1.
Figure 4 is a detail viewl of the automatic feed device.
Figure 5 is a detail view of the follower. Like characters of reference refer 'to' likel parts in all views.
Referring to the drawing in detail', 10 rep resents a bedplate or base of themachine which is provided with suitable braC-,lts or KEY-CUTTING MACHINE'.
1923. semi No. 629,447. if, .f
Mounted on the arbor or shaft 25 isa pair of cutters, numbered respectively, 27 and '28, The cutter 27 being a bevel cutter so as to cut keys which have irregularities of a sloprr Also mountedA on' ing or inclined nature. the'arborA 25 as above stated, isa cutter 28 which is particularly adapted for use in cutting square notches as willibe readily seen from the drawing.
Mountedin the lower part of the upright 13 andin another upright indicated at 29 and extending laterally therefrom, are screwn members 30 which lmay` be-adjusted .longi-Y-t tudinally ofthe arbor 25. Each of the mem-- bers 30`carries an adjustable guide 31 which may be adjusted transversely of the arbor so as to compensate for wear in the adjacent cutter. The `guide member 31 which co-operate'swith Vthe cutter 27 is formed with a beveled yend so as to follow the master key of which is pivoted an arm 36 which extends laterally of the machine and is formed at its ends with a pair of vises 37 and 38. Said vises having movable jaws so as to grip keys or key blanks. The key blank will be gripped in the vise 37 which co-opcrates with the cutters while the master key will be gripped in the vise 38 so that its edge may be moved along the edge of the guide member 31, and thereby effect the movement of arm 36 so as to draw the key blank toward and from the cutter in forming the duplicate key. The vises are guided in their lateral movement by a supporting and guiding plate 53.
As indicated in the drawing, the vises may assume different positions, one of which is shown in full line in Figure 1, and the other of which is shown in broken line. In the full line position the vises are co-operative with the cutter 23 and its respective guide member 31, while in the broken line position, the vises are operative with regard to cutter 27, and its respective guid-e member.
There are two springs in this machine, one of which is indicated at 39 and the other at 40. The purpose of the spring 39 is to mov-e the arm 36 and the attached vises into co-operative relation with the cutters, and the function of spring 40 is to move the arm 35 toward the right so as to position the key blank in operative relation to the cutter. However, when keys are being cut by a cutter 28 an-d such keys have deep notches, itis desirable that the springs 39 and 4() shall. be rendered practically inoperative so that the arm 36 may be moved manually about its pivot and so that the arm may be manually operated to feed the blank along as desired. For this reason the springs are connected in the manner which will now be described.
Spring is anchored at one end directly to the arm 35 and has its opposite end anchored in an eyelet extending from the edge of a disc 45 mounted on a pin having its bearing in a box or bracket 47 extending upwardly from the bed-plate 10. On the opposite end of this pin there is mounted a handle 48, and by turning this handle from left to right in Figure 1, spring 40 will be placed .under tension. As the handle 48 may be thrown slightly beyond its center,
it will strike against the bed-plate and will be held there by the tension of the spring without requiring the use of the pawl.
lVh-en it is desired to automatically feed the key blank to the cutter as will usually be the case when keys are cut by the bevel cutter 27, the springs 39 and 40 are both tensioned and then an automatic control of the feed is brought into play. This automatic control consists of a nut 49 mounted on the shaft 19 and provided with a rearwardly extending arm 50 which carries a stop or control number 51. Vhen it is not desired to have the automatic control operative, the nut 49 may be moved to the right hand end of shaft 19 which is not provided with threads, and operation of the shaft will not effect any lateral movement of the nut 49.
rlhe specific construction of the nut as shown in Figure 4 shows two parts 50a and 5'()b which are hinged together at the bottom and which are secured at the top by means of a member 52.
Mounted on the end of the arm 35 is a cam or handle 53, and when the automatic control is to be operative, this cam is moved down to the dotted line position and then the nut 50 is moved along the shaft 19 until one of the members 51 rests at either side of cam 53. By operating the handle 14, the nut 50 will be moved along the shaft 19 and will permit movement of the arm 35 by the spring 40 so as to feed the key blank automatically to the cutter.
'While I have described what I deem to be the most desirable embodiment of my invention, it is obvious that many of the parts may be varied without in any way departing from the spirit of my invention, and I therefore do not limit myself to the exact details of construction herein shown nor to anything less than the whole of my invention limited only by the appended claims.
What I claim isz- 1. In a device of the class described, the combination of an arbor, a cutter thereon, means for operating said arbor, a double vise for supporting a key and a blank, a guide member for co-operation with said key, a lever for operating said supporting means, a cam on said lever, and automatic means co-operative with said cam for controlling movement of said lever.
2. In a device of the class described, the combination of means for supporting a key blank, a plurality of cutters for co-operation with said means, and double vises co-operative with said cutters for moving a .key blank from co-operative relation with one of said cutters to co-operative relation with the other' of said cutters.
3. In a device .of the class described, the
lili',
lll)
combination of an arbor, a cutter thereon, means for operating said arbor, va double vise for supporting a key and a blank, a guide member for operation with said key, a lever for operating said supporting means, and means for efecting tensioning of said Spring.
4. In a device of the class described, the combination of an arbor, a cutter thereon,
means for operating said arbor, a double vise for supporting a key and a blank, a uide member for (zo-operation with said ey, a lever for operating said supporting means, a spring connected to said supporting means, and means for tensioning said spring.
In testimony whereof I affix my signature'.
AUGUST BIONDI.
