LEAD AND SLUG CUTTING MACHINE.
Application filed March 19, 1926. Serial No. 95,815.
My invention relates to a new and useful lead and slug cutting machine and it relates more particularly to a shearing device of this character, adapted to cut lead and slug and, particularly, strips of type metal.
With the above ends in view, my invention consists of a suitable stationary frame, having formed integral therewith suitable clamping means whereby the same may be secured in any convenient manner, to an upright post or standard, a table carried by said stationary frame, a. movable shearing member pivotally secured to said stationary frame,
an operating lever also pivotally secured to said stationary frame, shearing blades carried by said stationary frame and said movable shearing member respectively,'in operative alignment with each other, and means intermediate said operating lever and said movable shearing member for actuating the latter.
Forthe purpose of illustrating my invention, I have shown in the accompanying drawings, forms thereof which are at present preferred by me, since they will give in practice, satisfactory and reliable results, al-
though it is to be understood that the various instrumentalities of which my invention consists, can be variously arranged and organized and that my invention is not limited to the precise arrangement and organization of these instrumentalities as herein shown and described.
Referring to the drawings;
Figure 1 represents a front elevation of a novel lead and slug cutting machine embodying my invention. t
Figure 2 represents a side elevation of the same. I,
Figure 3 represents a side elevation, similar to that shown in Figure 2, viewed from the opposite side.
Figure 4 represents a section on line 44 of Figure 2.
Figure 5 represents a section on line 55 of Figure 2.
Referring to the drawings, in which like reference characters indicate like parts, 1 designates the frame of my novel device, comprising the laterally projecting clamping member 2, the downwardly inclined stationary shearing member 3, and the upper stationary lever arm or bracket 4. The clamp 2 is provided with a vertical semi-circular channel or recess 5, adapted to fit an upright standard 6, upon which the device is mounted; while a similar clamp member 7, also havmg a semi-circular channel therein, is adapt-- ed to be secured to the member 2, by means ofthe bolts 9, thereby rigidly to clamp the machine onto the said upright standard or support 6.
A laterally projecting inclined table 11 is securedto one side of the stationary lower shearing member 3, by means of screws 10, and is provided with a guide or. retaining strip 12 secured to the lower edge thereof, by means of the screws 13, and extending at a right angle to the shearing edge. On the other sideof the stationar shearing member '3, and near the upper end t iereof, a stationary shearing blade 14 is set in, as'shown particularly 1n Figure 5, and is secured rigidly in the rabbeted upper edge of said stationaryshearing member 3, flush with said upper edge and with said table 11, by means of the screws 15.
The upper movable shearing member 16, is pivotally secured to one side of the frame 1, by means of the bolt 17, the nuts 18, and the washer 19, as shown particularly in Figure 4. in operative alignment with the lower station ary shearing member 3. The upper or'movable shearing member 16 is provided with a boss or lateral projection 20, in order to pro vide a. better bearing surface for the pivot bolt 17. A spiral spring coil 21 is wound about said boss, and has one of the free ends I 22 thereof abutting the clamping member 2,
and having the other free end 23 thereof engaging a pin 24, which is fixed in the upper shearing member 16. The spring 21 therefore constantly urges the 'upper movable shearing member 16 in an upward direction and away from the lower stationary shearing member 3. The upper stationary shearing member is also provided with a shearing blade 25, which is similarly set into the lower rabbeted edge of the upper shearing member 16, and in operative alignment with the lower shearing blade 14, and secured thereto by means of the screws 26.
A bell-crank lever 27, having the long operatinghandle or lever 28, and the shorter arm 29, is pivotally secured to the overhanging lever bracket 4, by means of the pivot bolt 30 and the nut 31. The arm 29 0f the bell crank 27 is in turn operatively connected with the movable shearing member 16, by means of a pair of links 32, pivotally secured to the end of the arm 29 and the outer end of the movable shearing member 16, at its two ends respectively, by means of the pivot pins 33 and 34. Thus, a forward and downward deflection of the lever or operating handle 28,
in the direction of the arrow 35 will cause the upper movable Shearing member 16' also to be deflected downwardly,thereby to coaet with the lower shearing member 3.
In order to support and guide the outer free end of the upper movable shearing member 16, against'lateral thrust, occasioned by the shearing operation, and in order to insure acleanqcut surface and edge, without the formation of any burr, there is provided upon the outer end of the upper movable shearing member 16, a downwardly projecting arcuate guide tongue 36, securedthereto or formed integral therewith, and having its center at the pivot point of said upper movable shearing member. A corrcspondin arcuateguide channel member 37 is secured to the outer end. of the lower stationary shearing member 3, by means of: thesorews 88,-in operative alignment with said tongue 36; said'guide channel being adapted to receive said tongue 36 and to guide the same, thereby to provide lateral support for the tree end of the pivoted .niovableshearing member 16. It will now be apparentthat I have devised a novel and useful construction eta lead and slug cutting machine which embodies the teatures of advantage enumerated as desirable in the statement of. the invention and the above descriptionfand while I have in the present instance, shown and described a preferred embodiment thereof which will give in practice satisfactory andreliable' results it is to be understood that such embodiment is susceptible of modification in various particulars without departing "from the spirit or scope of'the invention or sacrificing any of itsadvantages.
-Having thus described my invention, what Iierally projectingtable carried by said stationary shearing member, having its upper surface flush with the upper edge of said shearing member, an arcuate guide tongue fixedjto the free end of the upper movable shearing member, an arcuate guide channel ,member fixed to the stationary lower shearing member for guiding said tongue, a shearing blade detachablysecured to each of the opposed edges of said stationary and movable pivotally secured to said frame in operative alignment with said lower stationary shearing member, a lower and upper shearing blade detachably secured to the stationary and movable shearing members respectively, in operative alignment with each other, an
arcuate guide tongue carried by the outer free end of said movable shearing member, an arcuate stationary guide'carried by the onterend ot said stationary shearingmember adapted to receive and guide said tongue. a laterally extending table carried by said lower stationary shearing member having its upper surface flush with. the upper edge of the same, an actuating bell crank lever pivotally secured'to said frame, an actuating link interconnectingone arm of said bell crank lever with said movable shearing memher, and a spring adapted to urge said-upper movable shearing member upwardly into the open. positionf r v 3. Adevice of the character stated comprising a fixed'fram'e, a stationary lower shearing member carried thereby, an arcuate guide of channel cross-section fixed to said lower shearing member, a movable upper shearing 'memb'er pivotallyv secured to said frame, an arcuatetongue of rectangular cross-section fixed to the il ree endot said movable shearing member for travel within said guide, an actuating lever pivotally secured to said frame, and a pair otlinks pivotally connecting said actuating lever .and said upper movable shearing member.
