Application August 10, 1936, Serial No. 95,127 2 Claims. (Cl. 45---138) This invention relates to a mattress tufting ie machine, for example, to the right side, as machine and particularly to a machine which is viewed in Fig. 1. Approximately at their cen intended to hold and compress the mattress, par ters the links i3 at each end of the machine are ticularly at the points at which tufts are to be connected together by the pivot i5. The other applied. ends of the links I3 carry pins I6 which slide One of the objects of the invention is to provide in slots I'I in pieces of metal I8 secured to the O1 an improved tufting machine. end members of the frames i5" and I i. It will A further object of the invention is to provide an improved tufting machine in which the mat tress can be readily compressed and moved in compressed condition into horizontal and vertical positions to facilitate the tufting operation. A further object of the invention is to provide an improved actuating means for compressing a ‘ is mattress. - A further object of the invention is to provide an improved frame construction for a mattress tufting machine. Other objects, advantages and capabilities of the invention will appear from the following de scription of a preferred embodiment thereof, taken in conjunction with the accompanying drawings, in which: Figure l is a plan View of my improved ma 25 chine; ‘ Fig.l 2 is a side elevation thereof, with parts broken away, taken on the line 2»-2 of Fig. 1; Fig. 3 is an end View of the machine showing the frames in spaced relation for the reception readily be seen from Figs. 3 and 4 that the links I3, together with the rods i2, serve to keep the two frames Iû and II parallel under all circum stances. At each end the frame I Si carries a bracket I9 which is of substantial Z-shape, as shown in Fig. 2. The brackets I9 carry outwardly pro jecting trunnions which are received in suit able bearings 2l mounted on the upper end of standards 22. These trunnions are preferably located approximately at the center of the com pressed mattress so that the frames when loaded and the mattress compressed, are substantially 0 balanced so that the system may be rotated eas ily. 'I’he standards 22 form part of a support ing frame which includes a longitudinal channel member 23 and transverse feet or supports 24. The feet 24 are rigidly connected to the chan 25 nel member 23, as likewise are the standards 22. The standards are suitably held rigid by means of straps 25 connected thereto and‘to projecting portions of the channel member 23. It will read of a mattress; Fig. 4 is a similar View showing the frames in ily be understood, with reference to Fig. 2, that mattress-compressing position, part of the stand which the frames Ii] and II, together with the mattress, may be swung. ard and adjacent elements being omitted for the sake of clearness; Fig. 5 is an elevational view of the opposite end of the machine showing the frames in mat tress-compressing relation and swung into ver tical position, the operating handle at the oppo site end of the machine and part of the stand ard being omitted for the sake of clearness; Fig. 6 is a sectional detail on a larger scale, taken on the line E--~6 of Fig. 3, and Fig. '7 is a sectional detail on a larger scale, taken on the line ‘I-T of Fig. 1. Referring to the drawings, the reference nu 45 merals I!! and II designate two frames which are of a size to enable them to receive between them a mattress to be tufted. These frames are relatively movable into their extreme positions '50 shown in Figs. 3 and 4. The frame I0 carries upstanding rods I2 which are received in open ings in the upper frame II so that the frames are maintained in register. A link I3 is pivot ally connected to each frame Ill and I I by piv ..55 ots I 4. These pivots are located on one side of the supporting frame provides an open space in On its under side the frame Iii supports a ro tatable shaft 26. At one end, that is, the left hand end as viewed in Figs. 1 and 2, the shaft 2S has rigidly secured thereto an actuating handle 21 of substantial length. The portion of the handle 2l adjacent the? shaft 26 is in the form of a hook so that this shaft may clear the brack 40 et I9 in moving between the positions shown in Figs. 3 and 4, and vice versa. It will be under stood that the actuating handle 2l' operates be tween the standard 22 and adjacent ends of the frames ID and ll. A link 228` is pivotally con as 01 nected to the shaft 21 and to the upper frame I‘I. 'I‘his link is bent, as shown in Figs. 3 and 4, so as to clear the bracket I9. rl‘he link 28 is located on the inner side of the operating han dle 2l and on the outer sides of the links I3 so that the handle 27 may be swung without it or the link 28 fouling other parts of the mecha nism. The outer end of the actuating lever 21, that is, the part remote from the shaft 26, is oíf 2,117,458 2 set as shown in Fig. 1, to enable it to be grasped by hand and moved past the frames Il) and I l. At the other end of the machine the shaft positions inwardly directed arcuate compressing 26 rigidly carries a hooked arm 29 which is ar members 45 are bellied inwardly so as to com ranged in alignment with the hooked end of the lever 21. The arm 29 is of the same shape as the hooked end of the lever 21 for the same rea son, that is, to enable it to clear the bracket i9 at the adjacent end of the machine. The arm 29 is connected to the center of the top vframe ll by a link 30 which is similar to the link 28 and located in alignment therewith. The lower frame i0 is secured in the horizontal or vertical position by means which will hereinafter be de scribed. The pivotal connections between the link 28 and lever 21 and between the link 30 and the arm 29 are arranged to pass the plane of the centers of the upper pivots of the links 28 and 30' and the center of the shaft 26. Conse 20 quently, when a mattress is inserted between the frames l0 and H, these frames being in the re lation shown in Fig. 3, and the lever 21 is thrown in the counter-clockwise direction into the po sition shown in Fig. 4, the upper frame ll is 25 drawn downwardly and the lower pivotal con nections of the links 28 and 36 move past the central vertical plane so that the frames are automatically locked in mattress-compressing relation. After the tufting operation has been 30 completed and the frames have been brought members 45 are mounted between adjacent strips 42. As best shown in Fig. '7, the compression press the mattress more strongly at their posi tions. The compression members 45 are provided with central openings 46 to enable the workman to tuft through the most highly compressed por tions of the mattress. The grid structures 4l be ing removable, they may be replaced by other grid 10 structures, giving a different desired tuft spacing. The grid structure 4l may be assembled from the strips 42 and 43 and the arcuate compression members 45 by welding. The operation is as follows: The frames are latched in their horizontal position by the latch 34 by merely moving them into that position. The lever 21 is swung into the position shown in Fig. 3 so as to distend the frames l0 and Il. A mattress to be tufted is then placed between the 20 frames so as to rest on the lower frame I0. The lever 21 is then swung in the clockwise direction, as viewed in Fig. 3, into the relation shown in Fig. 4. The mattress is thereby compressed and the portions of the mattress at which tufts are 25 to be applied are more strongly compressed by the compression members 45. As previously noted, the compression linkage is automatically locked in compression position. The latch 34 is then unlatched and the frames are swung in the 30 into- the horizintal position sho-wn in Fig. 4, the clockwise direction, as viewed in Fig. 4, until they lever 21 is swung in the clockwise direction and on the completion of the movement of the lever 21 the lower pivots of the links 28 and 38 are 35 located on the right-hand side of the central vertical plane so that the frames are automati cally lo'cked or held in the distended relation shown in Fig. 3. The finished mattress can now are latched in vertical position, as shown in Fig. 5. The workmen now perform the tufting op readily be removed. The lower frame I0 is provided on one side with a rail 3|, the major length of which is spaced outwardly from the frame towards the adjacent standard 22. The standard has formed thereon a bracket 32 which carries an inwardly _ projecting plate 33 which is adapted to engage the rail 3l when the frame is in its horizontal position. A latch 34 is pivotally mounted on the bracket 32 and is biased by a spring 35 into the position shown in Fig. 6. When the frames I0 and Il are swung from their vertical posi .50 tion shown in Fig. 5 into their horizontal posi tion shown in Fig. 4 (in the clockwise direction as viewed in Fig. 5 and in the counter-clock wise direction as viewed in Fig. 4), the rail 3l slips past the latch 34 into engagement with the 55 plate 33. The latch then closes into the position shown in Fig. 6 and the frames are held hori zontal until the latch 34 is released. When the latch 34 is released by moving its lower end in wardly, the frames l0 and Il may be swung in 60 the clockwise direction, as viewed in Fig` 4. When the frames are swung intoI a vertical posi tion the end of the rail 3| enters a recess 36 of the latch member 31 and the frames are locked in the vertical position. The latch 31 is pivot eration passing their needles through the aligned openings 46 of the two frames. When the mat tress has been completely tufted, the latch 31 is released and the frames are swung into horizon tal position, in which position they are held by the latch 34. The lever 21 is then swung in the clockwise direction, as viewed in Fig. 4, and the 40 frames are distended so that the completed mat tress may be removed. It will be noted that the compression linkage including the lever 21, arm 29, shaft 26 and links 28 and 3|] being exclusively mounted on the frames, swing with the frames 45 Vwithout relative movement thereto and maintain vthe frames in their position of adjustment until the lever 21 is actuated. Although the invention has been disclosed in connection with the specific details of a preferred 50 embodiment thereof, it must be understood that such details are not intended to be limitative of the invention except in so far as set forth in the accompanying claims'.
