FLORIAN' FOLDING- SCISSORS Filed March 1, 1957 - 2,126,699 Patented Aug. 16, 1938 2,1265% UNITED STATES PATENT OFFICE 2,126,699 FOLDING SCISSORS Berkeley Julian Florian, Plantsville, Conn. Application March 1, 1937, Serial No. 128,308 8 Claims. This invention relates to scissors and shears but more especially to improvements in folding scis sors which can be adjusted either into- extended operative condition or be folded up into small 5 compass, and the invention has for its main ob joct to provide an improved scissors of this type which may be of any desired size or design. It is also an object of the invention to provide a durable folding scissors instrument which can 10 be conveniently and safely carried in the pocket of a garment; which will be of simple and effi cient construction, and which can be produced at a low cost. To these ends I have provided an improved folding scissors instrument constructed and op erating as set forth in the following description, the several novel features of the invention being separately pointed out and de?ned in the claims at the close thereof In the accompanying drawing: Figure l is an elevation of a scissors constructed in accordance with this invention. Figure 2 shows the scissors of Fig. l in one folded condition. Figure 3 shows one of the scissor members con sisting of a blade section and a handle section, the two parts being shown as folded together. Figure 4 is an elevation of the inner side of one of the handle sections hereinafter described. Figure 5 is a section on line 5-5 of Fig. 4. Figure 6 is an edge view of the handle section shown in Fig. 3. Figure 7 is an elevation of the outer side of one of the blade sections. 35 Figure 8 is an elevation of the inner side of the blade section shown in Fig. '7. 30 Figure 9 is a top edge view of the blade shown in Fig. 8. ' Figure 10 shows the scissors of Figs. 1 and 2 in another folded condition. Figure 11 is a top plan view of the scissors shown in Fig. 10. Figure 12 illustrates one form of pivotal con nection by which the several parts of the scis sors are fastened together. Figure 13 shows an alternative form of piv otai connection. The embodiment of my invention illustrated in Figs. 1 to 12, inclusive, comprises two scissor or cutting members 9, 9 each of which includes a blade-section it] and a handle-section II, the two blade-sections being duplicates and the two handle-sections being duplicates. (01. 30-255) blanking dies and one forming die, the latter being employed to bend the handle-section blanks into their ?nal shapes. Or the bending of the handle-section may be effected by the same die mechanism by which it is cut out. Cl All four of these sections are pivotally con nected together by a single pintle or rivet I2. That is to say,. the single pintle or rivet l2’not only pivotally connects the two scissor members 9, 9 but it also pivotally connects the two sections 10 of each of said members. As shown in Figs. 4 and 5 each handle-section It comprises a shank portion l8 formed at its one end with an eye or ring 13 for the reception of a ?nger of the hand by which the instrument is operated, the inner marginal portion of this eye being rounded inwardly as shown at M, and at its opposite end with an aperture l5, Fig. 4, to receive the pintle I2 and with a longitudinal slit it which provides a resilient spring ?nger ll to co-operate with the hub of the blade sec tion l0 that is associated with said handle-sec tion; As shown in Fig. 5 the shank E8 of each handle section is of angle-iron shape in cross-section 25 and this angular shape provides an inwardly pro jecting ?ange l9 which extends throughout the greater portion of the length of the spring ?nger if and provides a stop shoulder 20 adjacent to the free end of said ?nger to co-operate with a shoulder 2!, Figs. 3 and 8, provided upon the hub of the blade section l0 that is associated with said handle section. At the end thereof that is in proximity to the ?nger-receiving eye l3, viz., at its outer end, the ?ange I9 of each handle-section H is made with a lug extension 22, Figs. 1 and 11, to co-operate with the blade-section of the other, or opposite, scissor member as presently to be described. In order to impart the desired strength and resiliency to the spring ?nger ll of each handle section the latter is spring tempered and because of the angular cross-sectional shape of said ?n ger, and the proximity of the inner end of slit IE to the ?ange l9, practically all of the flexing of ?nger ll toward and from pivot aperture I5 Fig. Li, will be localized adjacent to said inner end. Thus the opposite end portion of ?ange i9 that is adjacent to aperture I5 is not distorted from its ?at shape by movement thereof toward and from said aperture. When the several parts of the scissors are as Therefore, sembled and pivotally connected by the pintle .iese four sections H3 and H may be produced rivet l2 the spring ?nger ll of each handle-sec tion is under tension and at all times bears yield 55 at low cost from sheet steel by means of. two 55 2 2,126,699 ingiy against the hub portion 23, Figs. 3 and 8, edges of the blade sections, prevent further rela of the blade section If! however the latter may be tive movement of the latter. Continued move ment of the handle-sections thereafter moves them relatively to the closed blade sections until adjusted relatively to the handle-section. The hub portion 23 of each blade-section l0, Figs. '7 and 8, is formed with an aperture 24 to receive the pintle-rivet l2 while its periphery is made with two tangential ?at surfaces 25 and 26, the former surface 25 being disposed at one side of aperture 24 adjacent to shoulder 2| and the 10 surface 26 being disposed at the opposite side of said aperture 24, said two surfaces being also disposed obliquely relatively to each other as shown in Fig. 7. Between these two flat surfaces the periphery of said hub portion is made arcuate 15 and concentric with respect to aperture 24 as shown at 27. When the blade section occupies extended posi tion relatively to its handle-section the shoulder 2| thereof abuts the end of ?ange l9 at 20 while said ?ange bears ?atwise against the ?at sur face 25 of the blade section thereby to yieldingly hold the latter against closing movement rela tively to the handle section. Thus the ?ange IQ of each handle-section cooperates with the blade 25 section thereof to perform a double function in addition to a third function to be referred to presently. When the two members 9 of the scissors are in operative condition as shown in Fig. 1, relative swinging movement of the two members in a direction to close the blade section together is limited by the engagement of bosses 3! which project from the inner faces of the blade sec tions, each with the cutting edge of the opposite blade section. These bosses are struck up from the material from which the blade sections are made by the blanking die and therefore each boss is integral with its blade section and cannot work loose. Swinging movement of the two han 40 dle sections in the opposite direction ?rst opens the blade sections to their fullest extent as shown the shoulders 28 at the ends of the ?anges l9 abut the shoulders 2! of the blade sections which is the limit of adjustment of the two handle sections in that direction. The scissors is then in operative but closed condition. While being thus adjusted the engagement of 10: the ?ange portions E9 of the spring H with the ?at surfaces 26 causes each blade-sec tion to move with its handle-section as the two handle-sections are moved apart from the posi tions shown in Fig. 2 until the movement of the 15 blade sections toward each other is arrested by the stop bosses 3i, Fig. 1, and thereafter the en gagement of shoulders 29 and 2i occurs while the blades are closed which prevents further move ment of the handle-sections. It will be clear that when a blade section occupies the position shown in Figs. 2 and 3 the engagement of the ?ange IQ of spring ?nger E? with the ?at surface 28 of the blade section yieldingly opposes open~ ing movement of the latter, while further move 25 ment of the blade section toward the eye of its handle-section is prevented by the elevation 28 of the blade. The pintle rivet I2 is made at one end with a head as shown while the opposite end portion of its shank is made tubular and is upset as shown to permanently secure the parts together. Be fore upsetting the end of the shank of the pintle~ rivet a spring washer 32 is placed in position on the projecting end of the shank that is to be 35 upset. In Fig. 13 I have illustrated an alternative form of pivotal connection wherein each handle-sec tion il is pivotally and permanently connected with arateits tubular complemental rivet 33 made blade at section its outer 5% by end with 40 a ?ange 34 and having its inner end upset to in Fig. 10 which brings the back of each blade section into engagement with the lug 22 of the opposite handle-section, after which continued movement of the handle-sections on the pintle tion M1. rivet l2 in the same direction brings the two scissors members in this fashion a solid rivet 35 ?nger eyes 13 into register as shown in Fig. 2, the engagement of the outer free end portions of the blades with the lugs 22 of flanges l9 together with the engagement of an elevation 28, Figs. 7 and 8, on the hub of each blade section with its two members and upset as shown. With this construction illustrated in Fig. 13 the two sections of each scissors member are pivotally con50 nected by a rivet or pintle other than that which ?ange i9, preventing further relative movement of the two handle-sections in that direction. The elevation 28 on the hub of each blade section is made of su?icient height to co-operate with its ?ange I9 as a stop as described. That is, the radial distance of elevation 28 from the axis of the aperture 24, Fig. '7, is materially greater than the radial distance between said axis and the arcuate surface 21. After each blade blank is produced from sheet steel as above described it is ground away upon its outer face to bevel the same as shown at 29, Fig. '7, along its inner cutting edge 30. In adjusting the parts from their folded up inoperative positions shown in Fig. 2 the two handle-sections are swung apart on the pintle rivet [2 to the extent of nearly 180 degrees. When the scissors instrument is viewed as in Fig. 2 the nearest handle-section i! would be swung downwardly and the further handle-section up~ wardly to the extent described. The ?rst effect of this relative movement of the handle-sections is to close the two blades together until the bosses 3! Fig. 1, through engagement with the cutting fill a countersink provided at the inner end of the hole or aperture 26 formed in the blade scc~ After connecting the sections of two 45 is passed through the tubular rivets of the pivotally connects the two scissors members, whereas in Fig. 12 the single pintle-rivet 52 not only pivotally connects the two sections of each member but it also pivotally connects the two 55 members.
