mg. 17, 154 H. .1. SPENCER FASTENER APPLYING DEVICE Filed March 20, 1953 fiw IN V EN TOR.
Patented Aug. 17, 1954 UNITED STATES ATENT OFFICE 2 Claims.
This invention relates to improvement in stapling machines wherein a driver is actuated to drive a staple from an arm containing staples and spring means is usually employed to urge the staple-carrying arm or a clincher arm towards the opposite arm to grip material to be stapled, the spring in some cases being compressed as the driver is actuated.
One objeot of the invention is to provide means whereby pressure applied on a single lever is transmitted in part to the driver to actuate the latter and the balance of the pressure so applied is rigidly transmitted to one of the arms to urge the latter towards the opposite arm for gripping material between the arms as the applied power urges the driver to secure a staple in said material.
In the accompanying drawings which illustrate a present preferred embodiment of my invention Figure 1 is a sectional view in side elevation showing a plier type stapling machine embodying one arrangement of the operating lever used to actuate the driver and simultaneously urge the staple-carrying arm towards the staple clincher arm for gripping material therebetween.
Figure 2 is a view in side elevation showing the device in Figure 1 with the arms as having been moved towards each other and the driver as having been moved in fastener applying direction.
Figure 3 is a cross-section of Figure 1 at 3-3.
Referring to the drawings, the stapling machine comprises a magazine arm I which is of the usual type, containing an ejection shute II] at its one end, a reciprocably mounted driver 3 for ejecting the staple S, a staple pusher I I, a feeder spring I2 adapted to urge the pusher II to feed the staples S along the staple guide 2'! towards the ejection shute Ill and a feeder spring guide rod I3 for holding the feeder spring I2 in proper alignment. As shown in Figure 1, a block I4 is secured to the pusher II and feeder spring I2 is urging the pusher block I4 towards the ejection shute I0.
Note in Figures 1 and 3 that the inverted U- shaped bracket I6 is secured to the underside of the magazine arm I and has its flanges 28 pierced to receive shafts 5 and I. An anvil arm 2 contains staple clinching means 4 on its one end and arm 2 is pivoted in relation to the magazine arm I on shaft 5 to permit said arms one ends to move towards each other to grip material to be stapled. See Figure 2. A staple driving arm 6 is pivoted on the magazine arm I by shaft I, the latter being located at a point away from shaft 5 and thereby a part of pressure applied to the staple driving arm 6 is transmitted to the magazine arm l through shaft 1 to urge shaft 1 to move in an arc counter-clockwise around shaft 5 to thereby urge the ejection chute end ID of the magazine arm I towards the clincher means 4 of the anvil arm 2. See Figures 1 and 2. The staple driving arm 6 has upwardly extending sides 8 which are formed inwardly at 9 for entering opening 24 in the driver 3 and arm 6 is adapted thereby to transmit the balance of pressure applied to it to the driver 3 to reciprocate the latter. See Figures l and 2. As shown, the sides 8 of the staple driving arm 6 have an integral web portion 23 which forms the balance of the hand-grip and the latter underlies the magazine arm 5.
As shown in the accompanying drawings, the anvil arm 2 has side portions 2I extending upward on both sides of the device and are integral with a web portion 22 which extends longitudinally and overlies the magazine arm to form a part of a hand-grip opposite from the handgrip portion of the staple driving arm 5.
Notice in Figure 1 that the inward portion 9 of the staple driving arm 6 is against stop 25 of the anvil arm I to limit upward movement of the driver 3 relative to the magazine arm I and that lugs 26 on the staple driving arm 6 are in contact with the forward edges I5 of the side portions 2I of the anvil arm 2 to limit the counter-clockwise rotation of the latter on shaft 5.
A spring I! has its coils resting against the underside of bracket I6 at a point between the central portions of shafts 5 and "i. Spring I! has one leg I8 resting on the inside of the handgrip portion or web 23 of the staple driving arm 6 for rotating the latter clockwise on shaft 1 to thereby raise the driver 3 in relation to the magazine arm I and spring IT has its other leg I9 exerting pressure on pin 20 which is supported on the anvil arm 2 for rotating the latter counter-clockwise on shaft 5 for moving the clincher end 4 of the anvil arm 2 away from the ejection chute end ID of the magazine arm I.
In Figure 1 the device is shown with the anvil and magazine arms spaced apart to receive material, the driver 3 is in a raised position in the magazine arm I to permit a staple S to be moved into the ejection chute ID by the pusher I 1 under the influence of feeder spring I2 and under these conditions, the device operates as follows: the device is held in one hand and manual pressure is applied to the hand- grip portions 23 and 22 of the staple driving arm 6 and of the anvil arm 2 respectively; as pressure is applied as mentioned above, the coiled portion of spring I! is pressing against the underside of magazine arm I and spring has a leg I 8 restraining the staple driving arm 6 from pivoting counter-clockwise on shaft 7 and thereby in relation to the magazine arm 5. The other leg I9 of spring I! as previously explained is restraining clockwise movement of the anvil arm 2 on shaft 5 and is thereby restraining the clincher end 4 of the anvil arm 2 from moving towards the ejection chute end 50 of the magazine arm I. See Figure 1.
A study of Figures 1 and 2 will show that it is unimportant at the beginning of a fastening operation as to Whether the anvil arm 2 pivots on shaft 5 to move its clincher end 4 towards the ejection chute end ID of the magazine arm I or should the anvil arm 2 remain stationary While the magazine arm I is pivoted counter-clockwise on shaft 5 by the dual pressure by the coils of spring I! against bracket I6 which is secured to the magazine arm i and by the pressure transmitted from the staple driving arm 6 through shaft to the magazine arm I to move the latters ejection chute end it: towards the clincher end 4 of the anvil arm 2 with shaft '1 thereby moving with the magazine arm I in an arc counter-clockwise around shaft 5. See Figures 1 and 2.
Therefore, in view of the above explanation, as pressure is applied to the device at the beginning of a fastening operation, said dual pressure urges the magazine arm i to pivot counterclockwise on shaft 5 to thereby move the ejection chute end I0 of the magazine arm I towards the clincher end of the anvil arm 2 until such relative movement between arms I and 2 is stopped by contact with material placed between the latter arms. When the anvil arm 2 and the magazine arm I are stopped, as described, and further pressure is applied on the device, the staple driving arm 6 will pivot counter-clockwise on shaft l against the resistance of leg I8 of spring i? to thereby transmit part of the pressure applied on the driving arm 6 to the driver 3 to more the latter towards the clincher end t of the anvil arm 2 to thereby eject a staple from the magazine arm I into the material being gripped and the balance of the pressure being applied to the driving arm 6 is being transmitted through shaft 7 to the magazine arm I to rigidly urge the ejection chute end IQ of the magazine arm i to grip one side of the material during the fastener applying operation.
