v s'r s PATENT GEORGE WILLIAM DOVER, 0E CRANs'roN, RHODE ISLAND, ASSIGNOR T0 GEORGE W. DOVER, INCORPORATED, OF PROVIDENCE, RHODE ISLAND, A CORPORATION OF RHODE ISLAND.
METHOD OF MAKING PIN-IONGUES.
Patented J une 10, 1919.
Application filed December 26, 1918. Serial No. 268,298.
To all whom it may concern Be it known that I, GEORGE .WILLIAM DOVER, a citizen of the United States, residing at Cranston, in the county of Providence and State of Rhode Island, have in ends, the solid head has heretofore been formed integral with the pin, so far as known. In this construction where the pin portion is reduced down to form the pin, the pin does not have the same rigidity and strength as it would have if formed of spring wire also the pin is weak at the head end, is liable to bend out of shape and is easily broken when in use.
The object of my invention is to provide an improved method of making pin tongues whereby the pin may be made of a suitable spring Wire and the solid head of a different metal better adapted for the head, the pin tongue when completed having a spring wire pin and a solid head intimately and permanently secured in place, without solder.
My invention consists in a peculiar and novel method of making pin tongues, as will be more fully set forth hereinafter and claimed.
Figure 1 is a face View of a piece of sheet metal stock of a predetermined thickness and showing the first step of forming the pin holes in the stock.
Fig. 2 is a transverse sectional view through the pin holes in the stock, taken on line 2.2 of Fig. 1.
Fig. 3 is a face view of the stock from Which the head blank has been punched out, second step.
Fig. 4 is a face view of the punched out head blank.
Fig. 5 is a sectional view through the pin holes in the head blank, taken on line 5.5 of Fig. 4.
Fig. 6 is a view showing the means of insorting two spring wire pins into the pin holes 1n the head lank, third step.
Fig. 7 is a view showing the means of separating the head blank andforminga head on each pin, fourth step. I Fig. 8 is a head end view before compressing or swaging the head on to the pin.
Fig. 9 is a head end view after the head has been compressed or swaged on to the pin, fifth step.
Fig. 10 is a side view of the nearly completed pin tongue after the head hasv been swaged on to the pin, and V 11 isa side view of thefinished pin tongue showingthe pintle hole punched in the head, sixth and final step.
Figs. 1 to 7am enlarged and Figs. 8 to 11 still further enlarged.
In the drawing 12 indicates a piece of sheet metal stock of a predetermined thickness in which are punched two pin-holes 13.13 the required distance apart, as shown in Fig. 1.- 14 a rectangular shaped twin head blank cut out of the metal stock 12 and having the pin-holes 13.13 close to each end, as shown in Figs. 4 and 5. 15.15 spring wire pins each having a head end 16 and a pointed end 17. 18 a fixed abutment and 19 a movable member of a machine whereby the pins 15.15 are pushed point first through the pin holes in the head blank, as shown in Fig. 6. 20 a cutter which separates the head blank and forms a head on each pin and 21 a completed head having a pintle hole 22, as shown in Fig. 11.
My improved method of making pin tongues is as follows: Two pin holes 13.13 are punched through sheet metal stock the required distance apart, a twin head blank is then cut out of the stock having a pin hole close to each end, the head blank is then placed in a suitable machine and two pins are then inserted simultaneously point first, through the pin holes in the head blank, leaving the head ends of the pins in the head blank, the twin head blank is then out apart and formed into two heads, leaving a head on each pin, the heads are then placed in suitable dies and compressed and fiattened to the required thinness, thereby swaging the heads on to the head end of the pins, a transverse pintle hole is then formed in the heads, completing two pin tongues.
By the use of my improved method of making pin tongues it is evident, that any practical number of pin tongues may be made simultaneously, thereby saving in time and reducing the cost, and by making -on each pin, compressing the head blanks to the required thinness thereby swaging the head blanks on to the pins and'then forming a transverse pintlehole in each head blank. 1 r
2. The method of making pin tongues consisting in forminga pin hole in sheet metal stock of the required thickness,cut-
copies. of this patent may be obtained for five cents each, by addressing the ting out of the stock a head blank having the pin hole close to one end, inserting a pin, point first through the pin hole in the head blank, compressing thehead' blank to the required thinness thereby swaging the head blank on tothe pin and then forming a transverse pintle hole in the head blank.
3. The method of making pin tongues consisting in forming a pin hole 1n sheet metal stock of the required thickness, cutting out of the stock a head blank of the required form and having the pin hole close to one edge, insertinga pin, point first through the pin hole and leav-ing the head, end of the pinin the head blank, com-pressing the head blank to the required thinness thereby-swaging the head blankjon to the head end of the pin and then forminga transverse pintle holein the head blank.
'In testimony whereof I have signed my name to this specification. 1
