DESK STAPLING MACHINE Filed Feb. 9, 1929 Patented Aug. 26, 1930 UNITED STATES PATENT ornca FRIDOLIN POLZER, OF NORWALK, CONNECTICUT, ASSIGNOR TO THE E. H. HOTCHKISS COMPANY, OF N ORWALK, CONNECTICUT, A CORPORATION OF CONNECTICUT DESK STAPLINGI MACHINE Application filed February 9, 1929. Serial ,No. 338,832.
This invention relates to stapling machines and more particularly to an improved means for clinching the staples, and has for an object to provide a clinching means for stapling 5 machines which will so clinch the staple that it will lie flat against the surface of the Work thus overcoming the objection to the manner in which the staples are set by the ordinary stationary curved anvil which leaves the sta- 10 ples curved so that they project an undesirable distance above the face of the work.
It is also an object of the invention to pro vide a stapling machine in which the staples may be set in different manners by shifting or changing the clinching means.
With the foregoing and other objects in view, the in v'ention consists in certain novel features of construction, combinations and arrangements of parts as will be more fully disclosed in connection with the accompanying drawing. In this drawing,
. Fig. 1 is a side elevation and partial section fof a stapling machine provided with my improved construction.
Fig. 2 is a front elevation thereof.
Fig. 3 is vertical section through the stapling means showing the manner of clinching the staple.
Fi 4 is a vertical section through the base just forwardly of the clinching anvils, showin them in the ordinary position of rest.
"ig. 5 is a similar view showin the use of two anvils having a different efiect on the sta le.
Fig. 11 is a section through a card or simi lar article showing how the staple may be ap lied for hanging the card on a wire or similiar support.
The machine comprises the usual base 12 to which is pivoted the housing 13 at 14 carrying the vertically reciprocable plunger 15 1g. 6 1s a similar view showlng stlll'an held in the upper position by a spring 21,
either outside or inside the housing as desired. This plunger may be of the t pe disclosed in my prior Patent #l,588,990, une 15, 1926.
It will, of course, be understood that when the plunger is depressed it carries down the forward staple and drives it through articles to be stapled, such as sheets of paper 22, placed under the housingand on top of the anvil.
My improved anvil construction is mounted in a block 23 carried by the base 12 under the forward end of the housing. This block has a transverse slot in which are mounted the movable anvils or staple clinching means. In Figs. 2 and 3 there are two anvils 24 each pivoted in the block at 2 5 on opposite sides of the plunger, the pins 25 being removable and extending transversely through the block and have knurled heads 26 to be grasped by the operator for inserting or removing these pins. Mounted below the base 12 is a resilient plate 27 which is secured at its rear end to the under side of the base by any suitable means, such as the screws 28. This plate is curved so that at its forward end it is normally spacedfrom the lower surface of the base, as shown in Figs. 1 and 2. In other words the base is supported a suitable d'stance above this plate and the forward ends of the housing and plate are movable relative to each other. Coil springs 29 may also be placed between the base and this plate to assist the plate supporting the base but permit the relative movement between the two. Carried by the base plate 27 is an upright block 30 which is recessed at its upper edge and on which the pivoted anvils 24 rest.. When the machine is not operating the elements are in the position of Figs. 1 and 2. If now it is desired to staple sheets of paper 22 for instance the forward end of the housing is raised and the paper is inserted beneath the housing on top of the and the upright member because down-' ward movement of the plunger relative to the housing is limited by any suitable means, such as the shoulder 43 on the plunger engaging-the stop 44 in the housing. This causes the upper ends of the member 30 to 'push upwardly on the lower sides of the anvils 24 and swing them about their pivots to the horizontal position of Fig. 3. While they swing to this positon the anvils engage the prongs of the sta le and fold them against the under side 0 the work, as shown in Fig. 3. When the machine is in the position of rest the upper edges 31 of these anvils are inclined downwardly and inwardly, as shown in Fig. 2, so that the ends of the prongs are bent slightly inward as they hit these upper edges and then are pressed tightly against the under side of the work as the anvils are swung upwardly to the position of Fig. 3. It is preferred also that the upper edges of these anvils be grooved,
as shown at 32, tobetter hold the staples in proper position. It will be seen from this operation the prongs of the clinched staple s own at 16', Fi 3, are pressed flat against the under side 0% the work and are not left curved as is the ordinary operation of a machine using a stationary anvil, because the stationary anvil in order to properly bend the pron must have curved bending surfaces an they, therefore, leave the prongs curved so that they roject an undesirable amount above the sur ace of the work. With this present construction, however, the
rongs are laid perfectly fiat giving a much tter clinching effect and as the staple does not project so far from the surface of the work they are much less liable to catch on other objects.
Figs. 4 to 8 inclusive are views showin different arrangements which may be used for the anvils to secure different effects. In Fig. 4 the anvils are practically the same as those of Fi 3 but lnstead of the single operating bloc 30 of Fig. 3 there is an upwardly extending post 33 for each anvil. The operation is the same, however, as Fig. 3 and the staple 16 is set in the same manner.
In Fi 5 one of the anvils, indicated at 34, is o lessheight than the other anvil so that when the anvils are forced upwardly one prong 35 folded by the anvil 24 is pressed against the under side of the work in the usual manner, but the other rong 36 is not forced up against the work y the anvil 34 but is only partly clinched leaving a hook.
Therefore, if the prong 35 is clinched-- through a card 37 for instance, as shown in to bend in the prong 36 only part way.
In Fig. 7 the result is practically the same as that of Figs. 1 to 4. Here the free ends of the anvils 39 rest on the top of a block 40 carried by the base plate 27 so that as the base 12 moves downwardl the block 40 forces the anvils up to clinch the staple 16, as shown in Figs. 3 and 4.
Fig. 8 illustrates how the anvil may be arranged to clinch the staple for a temporary bond. Thatis, the prongs ofthe staple are so set that the staple may be easily removed and the sta pie is not as permanentl set as in the other forms. It will be note that the block 23 is provided with three transverse openings in any one of which the ins 25 may be placed. If the pins are places in the two outer openings 41 the anvils are inclined downwardly and inwardly toward each other so that they operate .to bend both prongsof the staple inwardly toward each other. If, however, one of the pins 25 for one of the anvils is placed in the central openin 42, as indicated in Fig. 8, both anvils wil be inclined in the same direction, and therefore, when the machine is operated both prongs will be bent in the same direction. That is, one prong 35 will be bent inwardly by the left hand anvil as in the other forms while the other prong 4.3 will be bent outwardly by the other anvil making a staple much more easy to remove from the articles stapled if it is desired to unstaple them.
Therefore, with the construction arranged too as illustrated different shapes of anvils may be used to have different effects on the prongs of the staples, or the anvils may be of different arrangements to have different effects on the prongs of the staples.
