Pinto N. rnnnomorrirrssnne, PENNSYLVANIA, ASSIGNOR TO THE A. FRENCH SPRING COMPANY, (LIMITED,) OF SAME PLACE.
MACHINE FOR STRAIGHTENING AND NIBBING SPRING-LEAVES.
SPECIFICATION forming part of Letters Patent No. 345,629, dated July 13, 1886.
Application filed March 1 1886.
To all whom it may concern:
Be it known that I, PHILo N. FRENCH, residing at Pittsburg,in the county of Allegheny and State of Pennsylvania, a citizen of the United States, have invented or discovered certain new and useful Improvements in Machines for StraighteningandNibbing Spring- Leaves, of which improvements the following is a specification.
In the accompanying drawings, which make part of this specification, Figure 1 is a top plan View of my improved straightening and nibbing machine. Fig. 2 is a sectional elevation of the same on the line at at, Fig. 1.' Fig. 3 is a similar view on the line g y, Fig. 1. Fig. 4 is a sectional elevation, on an enlarged scale, of the nibbing-head. Fig. 5 is a top plan view of the head.
The invention herein relates to certain improvements in mechanism employed in manufacturing elliptic springs, and has for its object the simultaneous straightening and nibbing of the leaves composing such springs, preparatory to subsequent operations.
In general terms, the invention consists in the construction and combination of parts, substantially as hereinafter described and claimed.
Along one side of the bed or frame 1 are formed suitable bearings,2,in which is mounted the shaft 3, said shaft being provided at suitable intervals with eccentrics or cams 4. Around these cams are placed the straps 5, which are connected by an arm, 6, to the slide or straightening-plate 7, mounted on suitable ways or beds, 8, formed on the upper side of their working-faces, are formed the longitudinal water-tubes 13, provided at their ends with suitable, supply and discharge pipes, thereby Serial No. 193,605. (No model.)
preventing any undue heating and consequent distortion of the plates.
On the bed or frame 1, just in the rear of the reciprocating plate 7, are formed bearings 14, in whichare mounted the journal-pins of the vibrating arm 16. In the rear end of this arm 16 is formed a recess for the reception of j ournal-blocks 17 ,surrounding a crank, 18, formed on the shaft 3, these blocks 17 being held, in place in the recess by the cap-bar 19, as shown in Fig. 2.
In the front end of the arm 16 is formed a slot, 20, for the reception of the holder for the nibbing-punch 21. This holder consists of a squared shank, 22, fitting in the slot 20, a cylindrical portion, 23, below the shank, provided with suitable screw-threads for the reception of the nut 24, and a threaded stud at the upper end of the shank, on which are placed the washer and nut and 26, the washer being of sufficient diameter to extend beyond the edges of the slot 20. The nibbing-punch is held within the cylindrical portion of the holder by the set-screw 27, and its vertical adjustment is effected by raising or lowering the holder by means of the nuts 24 and 26, as will be clearly understood.
Through the cap-piece 28 of the slot 20 is formed a threaded hole for the adj ustingscrew 29. The inner end of saidscrew, passing through the vertical slot 30 in the squared shank 22, is attached to the shank by means of the washers 31, arranged on opposite sides of the shank. This adjusting-screw is employed for effecting a horizontal adjustment of the punch-holder.
In the bed or ways 8 is formed the transverse groove 32, in which is placed the steel die 33, having the perforation 34.. This die is connected to the adj listing-screw 35, passing through a rim along the front side of the bed or frame 1, and employed in connection with the punch 21, for forming the nib on springleaves. y
In operating my improved machine the anvil-plate 9'is adjusted transversely in accordance with the width of the'spring-leaves to be straightened, and the punch-holder and die 33 are correspondingly adjusted.
In adjusting the anvilplate 9 care should be taken that the spaces between the operative edges of the anvil-plate and the reeiprocating slide shall be equal to the width of the spring-leaves when the slide is at the forward limit of its movement, as if said space were less than the width of the leaves the latter would be bent or its edges upset in the straightening operation.
To facilitate the placing of the leaves in position a movable stop, 36, is adj List-ably attached to the bed between the straighteningplates, an undercut groove, 37, being formed in the bed between the plates for the reception of the head of the stop clamping-bolt 38.
A plain groove, 39, -is formed in the bed at its opposite end,to enable the operator to readily grasp the leaves with his tongs in removing them from the machine.
If desired,two or more nibbing-pnnches may be attached to the vibrating head, a corresponding perforated die being placed in the bed.
If desired to form holes entirely through the spring-leaves, the punch 21 should be ad justed down by means of the nuts 24 and 26 the necessary distance. 2 5
I claim herein as my invention- 1. In a machine for straightening and nibbing spring-leaves, the combination of an adjustable anvil-plate, a reciprocating bendingplate, and an adjustable punch, substantially 0 as set forth.
2. In a machine for straightening and nibbing spring-leaves, the combination of an adjustable anvil-plate, a reciprocating bendingplate, an adjustable punch, and an adjustable 3 5 perforated die, substantially as set forth.
In testimony whereof I have hereunto set my hand.
