STATES PATENT OFFICE.
RONALD F. MCFEELY, 013 BEVERLY, MASSACHUSETTS, ASSIGNOR TO UNITED SHOE MACHINERY COMPANY, OF PATERSON, NEW JERSEY, A CORPORATION OF NEW JERSEY.
TACK-FEEDING MECHANISM.
To all whom it may concern:
Be it known that I, RONALD F. MGFEELY, a citizen of the United States, residing at Beverly, in the county of Essex and Commonwealth of Massachusetts, have invented certain Improvements in Tack- Feeding Mechanisms, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.
This invention relates to machines for inserting fastenings and particularly to mechanism for feeding the fastenings.
The invention is herein shown as embodied in the tack-supplying and feeding mechanism of a lasting machine of the type illustrated in United States Letters Patent No. 584,7 44.
An object of this invention is to provide improved means for controlling the feeding of tacks whereby delivery of tacks can be suspended while the machine continues in operation.
An important feature of this invention consists in means adapted to be rendered operative by the machine operator for stopping the delivery of tacks while the mechanism for actuating the tack-delivering devices continue in operation. To this end I connect the tack-delivering device with its actuating mechanism by means including a yielding element and arrange means which is adapted to be manipulated for modifying the movement of the delivering device. In the preferred construction the movement of "the delivering device is entirely suspended by a latch which is adapted to be moved into and out of operative position, the movement of the actuating mechanism being taken up by the yielding element when the latch is in its operative position. Preferably also the latch will be connected with operating devices which extend into position to be engaged by the shoe as. it is presented in tack receiving position, whereby the latch is set by the shoe topermit the delivery of tacks while a shoe is in position to receive them and is set to stop the delivery of tacks when a shoe is removed.
A valuable characteristic of this invention is found in the fact that the latch is arranged to stop the delivering device in its next delivering movement after the shoe is withdrawn whereby no tack will be wasted Specification of Letters Patent.
Application filed May 16, 1908.
Patented June 25, 1912.
Serial No. 433,274.
so that after the latch is withdrawn by the representation of the work the delivering device can discharge a tack at its next forward movement. In the arrangement shown the yielding element referred to is put under compression during the movement of the actuating mechanism in its back stroke and expands to produce the forward movement to deliver the tack. The latch is arranged to lock the delivering device with said yielding element under tension while the actuating mechanism continues to reciprocate. \Vhen the latch is withdrawn said yielding element can at once actuate the delivering device to discharge a tack without necessarily waiting for the usual actuating mechanism to operate in its regular time.
The several features of the invention, including certain details of construction and combinations of parts, will be more fully explained in connection with the following description of a preferred embodiment of the invention and will then be pointed out in the claims.
Figure 1 is a side view. Fig. 2 is a plan view, partly in section. Figs. 3 and 4 are modifications.
The machine comprises a raceway 2 having one or more grooves through which tacks are supplied to the separating and delivering devices, which, as herein shown, comprise a separating blade 4 and a delivering plate 6 movable between the end of the raceway and the delivering table 8. The separating blade is arranged to pass between the shank of the end track and the next tack in the groove that is feeding the tacks while the delivering plate has a pointed finger 1O thatengages the end tack at or near its head and wedges the tack along the oblique slot 12 over the delivering. table toward the discharge opening 14 in the table. From this opening the tack falls into the tack and driver passage of the reciprocating tack block 15 which has suitable fingers for suspending the tack in the passage. The tack block is attached to the slide 16 which by suitable mechanism, not herein shown, is
reciprocated forwardly from the tack-receiving position of the block under the delivering table to a position over the work and under the driver 18.
A cam plate 20 is secured between the slide 16 and the tack block 15 for recipro-. catory movement therewith and engages a' roll 22 on a lever 25, which comprises two members pivoted at 26 and held yieldingly in a predetermined relation by a spring plunger 27 and an adjusting screw 28. The plunger forms provision for the lever to yield, to prevent breakage, in the direction in which it is rocked in an otherwise unyielding manner by the cam plate 20 as the tack block advances from its tack-receiving position. The lever 25 has toothed engagement with a rack bar 30 to which the separating and delivering devices 4 and 6 are attached and in the described movement of the lever and the tack block said devices are moved toward the right into position to permit the end tack to slide past the separating blade into the delivering plate ready to be carried by the latter over the delivering table to the discharge opening 14 by the reverse movement of said devices and the lever. This reverse movement is effected by aspring 35 which is arranged in Fig. 2 to press the roll 22 toward and against the cam plate and is put under tension by the cam plate in the forward movement of the latter. During the rearward movement of the cam plate and the tack block, in which the latter returns to tack-receiving position, the spring 35 yieldingly actuates the tack-feeding devices to feed a tack and deliver'it to the tack block.
In Figs. 3 and 4 a cam plate 20 having a closed slot is shown and the spring plunger 27 and the adjusting screw 28 are transposed.
A projection from the right-hand end of the rack bar 30 has on its front side a shoulder 40 and mounted in a bracket 42 is a rock shaft 44 which carries a latch 45. This latch is arranged to engage the shoulder 40 and lock the rack bar and the parts connected with it from movement by the spring 35 or the plunger 27 to deliver and discharge the tack which is suspended in the delivering plate at the time said movement is about to take place. A spring 46 presses the latch normally toward locking engagement with the shoulder 40 and the upper arm of the rock shaft is connected by a rod 48 with an operating device 50. This operating device is shown as pivoted on the bottom rest against which the sole of the shoe being operated upon is upheld and said device is formed as an angle lever having an arm or foot which projects below the bottom rest into a position where it necessarily is engaged by the shoe in presenting the latter in position to receive a tack. By
this arrangement the latch is always withdrawn from locking position during the movement of the shoe into working position and the withdrawal of the latch will, it should be understood, immediately permit the spring 85 or 27 to act for delivering a tack to the tack block. This provides that a tack will be delivered to the tack block and presented by said block for driving in the same cycle of the machines operation in which the shoe is presented in tack receiving position so that no time is lost in wait ing to get a tack after presenting the shoe. Also it will be observed that the withdrawal of the shoe from tack-receiving position permits the spring 46 to act instantly to throw the latch into position to stop the delivering devices with the next separated tack ready to be delivered. Thus no tacks are wasted by being driven after the shoe has been removed.
As has been indicated, the invention may be used with advantage in a lasting ma.- chine. Such machines usually comprise numerous other instrumentalities besides the tack mechanism and the machine as a whole will, as is usual, be connected with suitable starting and stopping mechanism. The provision of the independent means for starting and suspending the delivery of tacks according to the position of the work prevents the waste of tacks when the operator withdraws the shoe for one reason or another, as often occurs, without stopping the machine.
Having explained the nature of this invention and described a preferred construction embodying the same, I claim as new and desire to secure by Letters Patent of the United States:
1.
