FEEDING MECHANISM FOR SlDE-SEAMING MACHINES.
SPECIFICATION forming part of Letters Patent No. 734,760, dated July 28,- 1903 Application filed March 5, 1903. Serial No. 146,420. (No model.)
To all whom it may concern:
Be it known that I, CHARLES W. SLEEPER,
a subject of the King of Great Britain and Ireland, residing at Lancaster, in the county of Coos and State of New Hampshire, have i11- vented certain new and useful Improvements in Feeding Mechanism for Can-Scanning Machines, of which the following is a specification.
My invention has special relation to improvements in the feeding mechanism described in Letters Patent of the United States No. 585,635, dated June 29, 1897; and it consists in the use of improved stop-guides forguiding the front end of the body-blank and holding it accurately in position before it is acted upon by the forming mechanism, and also in the use of improved mechanism for.
the operation of the feed-finger.
In the drawings annexed to this specification, Figure 1 is a front view of the entire seaming-machine. Fig. 2 is a plan of the tinfeeding table and guides. Fig. 3 is an end view of the tin-feeding mechanism. Fig.- 4
'is a detail of mechanism for operating the lever by which motion is given to the feed finger.
The seaming-machine illustrated in Fig. 1 is fully described in the specification forming a part of Letters Patent for improvement in side-seaming machines, No. 698,066, granted to the American Oan Company as my assignee, April 22, 1902.
It consists, essentially, of mechanism for feeding the blank tin plates to the position where they are to be operated upon by the forming mechanism, mechanism for wrapping the blank around a cylindrical former, mechanism for forming the interlocking side seam,
A is the base of the machine. A Upon this is the column A, upon which is mounted the greater part of the operating mechanism.
A is a shaft passing through the column A and carrying the driving-pulley A and pinion A*, which engages a gear A on the camshaft A carrying the cam a.
a is a table secured to the column A for carrying the tin plates to be used in forming can-bodies.
a a? are T-slotted brackets secured to the table a by screws passing through suitable slots in the flange of the table a and capable of both vertical and horizontal adjustment. a and a are angle-iron guides adjustably secured to the brackets a a by suitable screwbolts, which engage T-slots in the tops of said brackets.
a is a block carrying the feed-finger a and sliding on a bar a secured to the brackets a a The block a is connected by a link 0. to a lever 0 pivoted at its lower end to the base of the machine and connected by a link of, pivoted to said lever a by the pin a to the slotted crank a a projecting stud a on the end of said link a engaginga slot in said crank a An Oscillating movement is given to the crank a by means of the pinion a engaged by the rack a to which reciprocating motion is given by the cam e Dotted lines, Fig. 4, show the position of the crank a and lever a at the inner throw of the crank, at which point the crank and link a should be upon a dead-centerthat is, the center of the crank-shaft, the stud c0 and the pin a. should be in a straight line, by which arrangement a slight Variation in the position of the rack 00 due to the wearing of the parts or any other cause, will not materially affect the position of the lever a or the accuracy of the feeding mechanism.
a is a bracket secured to the column A opposite the table a.
60 is a T-slotted bracket secured to the' bracket a and provided with means for vertical and horizontal adjustment.
a a are stop-guides adj ustably secured to the bracket 0. and presenting a flaring recess to the sheets of tin B as they are pushed forwardbetween the guides a a the bottom of said recess being just wide enough to receive and hold the sheets, whereby the sheets are accurately alined and held in place to be acted upon by the forming mechanism.
In operation the body-blanks B are placed able guides a a sliding block a feed-finger a and means for giving said slidingblock reciprocating motion, the guides (L16 0, being adapted to direct the forward end of the canblank as it is pushed forward and to hold it in position for the forming mechanism substantially as described;
2. In a machine of the, class described the described mechanism for operating the oscillating lever a by which reciprocating motion is given to the feed-finger, consisting of the link a pivoted at one end to said lever a and at the other end carrying the stud a Working in the slot of the crank a slot-ted crank a pinion a rigidly connected therewith, and rack (L12 engaging said pinion and operated by the cam c0 substantially as described.
