To (ZZZ whom it may concern Be it known that I, BENJAMIN W.

TUonn-n, a citizen of the United States, and

a resident of Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Tacking Devices, of which the following is a full, clear, and exact description.

This invention relates more particularly to a tacking device for a machine such as is disclosed in Reissue Patent No. 12,445, granted to Ephraim 0. Engberg, February 6, 1906, and is a division of Patent No. 976,640, granted to me Nov. 29, 1910.

The primary object of the invention is to provide simple and efficient means whereby one or more tacks may be automatically col lected and properly held in position, and the said tacks forced into a shade-roller to fasten the shade material thereto.

A further object of the invention is to provide simple and eflicient means whereby the material may be automatically forced around the shade-roller into tacking position and to brace tlte shade roller during the tacking operation.

The invention will be hereinafter more particularly described with reference to the accompanying drawings, which form a part of this specification, and will then be pointed out in the claims at the end of the description.

Figure 1 is a vertical longitudinal section of one form of device embodying the invention, showing how the device may be applied to a window shade machine, only a part of which is illustrated. Fig, 2 is a partial side elevation. Fig. 3 is a detail view of the means for intermittently rotating the tack collecting device. Fig. 4 is a sectional plan view of the device. Fig. 5 is a front eleva- Specification of Letters Patent.

usual roller, it will be understood that said device may be used in other relations, and for other purposes, and that some of the parts may be dispensed with, or others substituted therefor, without departing from the character of the invention.

The shade-roller holding means is located at the front of the machine and is adapted to removably hold the shade'roller 20. Adjacent to the shade-roller holding means is a transverse brace or bar 21 to which are secured a series of strips or plates 22 that extend inward and are adapted to support and guide the shade material as it is fed in position to be fastened to the shade-roller. The shade-roller 20 is supported by a springpressed center or device 23 which is slidingly held in the bearing 24, said bearing being adjustable along a support or slide 25. A chuck 26 supports the other end of the shade-roller and is provided with projections to engage and rotate said roller. The chuck and its shaft or spindle 27 may be also made adjustable transversely if desired, said spindle being journaled in bearings 28 and 29. On the end of the spindle 27 is a grooved pulley 30 which is rotated by a belt 31, the said belt being adapted to slip when the material is wound tight on the roller. The parts just described are substantially the same as in the patent and application referred to.

As shown the material is adapted to be fastened to the shaderoller by a single movement of a part of the machine. The

a support or slide 25. Figs. 1, 6 and 7, is held to move vertically in guides on the machine frame 32, and entering recesses in the sup port are the ends of the levers 33, which are pivotally held to the shaft 34, and have their other ends connected to rods 85. The lower ends of the rods 35 are fastened to a treadle 36, by which the work support 25 is raised when the forward end of said treadle is depressed, a spring 37 being provided to assist in restoring the treadle to its former position. On the support or slide 25 is the ad justable bracket 38 in which the bearing 2-lis vertically movable, and a second bracket 39 in which the bearing 28 is vertically movable. A third bracket a0 is secured to one end of the support 25 in whichthe bearing 29 is vertically movable. The bearings 24-, 28 and 29 carry the shade-roller holding means, and each bearing is normally forced downward in its bracket by a spring ll. Beneath the shade-roller is a shaft -12, along which are a series of anvils or braces d3. These braces are adjustable along the support 25 by the bolts or screws 44; and have projecting ends to hold and guide the forward end of the shade preparatory to fastening it to the shade-roller. To the shaft 42 are fastened a series of curved fingers 45, adapted, when the shaft is rotated, to force the end of the shade around the roller into fastening position. The ends of the shaft 42 are held in brackets on the support 25, and on each end of the shaft is a segmental gear 46, which is adapted to mesh with the teeth of racks 4L7, fastened to the fixed bar 21, so that the support 25 when moved vertically, will rotate said shaft. Each gear 46 has a foot 48, which is adapted to engage and slide along a straight part of its rack during the upward movement of the support and as soon as the gears are disengaged from the racks. This holds the fingers d5 in a raised position and until the gears again engage the racks as the support 25 is lowered, thereby releasing the fingers and forcing them downward. In the path of the bearing 29 is a bolt 4-9 which is held in a fixed bracket 50 and is adapted to engage the bearing 29 when the support 25 is lowered. The purpose of this bolt is to raise the spindle 27, the shade-roller 20 and the connections above the braces or anvils 43 to permit the shade-roller to rotate and wind the shade thereon and to permit the forward end of the next shade to be fed beneath the shade-roller and over the braces and the fingers. A second stop or bolt may also be provided to raise the bearing 24- and to work in connection with the bolt 49. By this means a brace is provided under the shade-roller at each point where a tack is to be driven into said roller, and the forward end of the shade is automatically forced around the roller ready for tacking.

The shaderoller it is raised by the lifting of the support 25 is moved toward a collecting or receiving device 51. This device may be of any suitable form. As shown the device is rotary and comprises a series of radial permanent magnets 52. These magnets form arms and are fastened to a sleeve 53 which is held to rotate in a frame 54. The sleeve is splined as to slide along the shaft 55, there being a series of such devices and frames according to the number of tacks to be driven into the shade-roller. The shaft 55 and tack-collecting device 51 rotate intermittently, and the separate arms or magnets are successively brought to a point adjacent to a tack-conveying chute 56 forming a continuation of a hopper 57. This hopper is loosely supported on a shaft 58,

and at its forward end is loosely held on a shaft 59. There is a hopper for each collecting or receiving device 51 and both hopper and device are movable together with the frame 54, which latter is adjustably held to the transverse bar 60 by the bolts 61. To the shaft 59 is fastened a collar 62 for each hopper, and to the collar is fastened the plate 63 forming the bottom of the hopper. An arm 64: is held on the shaft 59 at one end, and in the path of said arm is a rotary star or toothed wheel 65 fastened to the shaft 58. The shaft 58 has a pulley 66 fastened thereto, which is driven by a belt 67 from a suitable drive pulley,'so that as the shaft 58 is rotated the hopper bottoms will be vibrated to agitate the tacks in the hoppers and cause them to pass down the chute 56. This chute has a slotted bottom or guide 68 and a yielding plate or member 69 over the guide. The heads of the tacks are next the yielding member, and the latter has an inturned end 70 which holds the tacks in the chute until released.

The shaft 59 at one side of the machine has a lever 71, Figs. 2 and 4;, and at the other end an arm 72 that support said shaft 59, the other end of the lever being in the path of a projection 73, Fig. 4 on a reciproeating part of the machine, not shown. The lever is forced in one direction by the springs 74:, and when moved in the opposite direction by the movable projection 73, the hoppers will be moved or rocked so as to throw the lower end of the tack chute away from the tack collector or device 51. The inturned end 7 0 will engage the stop 75 on the frame 54:, and will raise the yielding member as in Fig. 1, to release one tack of the row, the remainder of the row being held by the part 76 of the stop, which enters between the two lowest tacks. The tack that is released is held by the end of the chute, and as soon as the projection 73 is operated each hopper will return to the position shown in Fig. 7, which will permit the magnetic arm adjacent thereto to remove the released tack from said chute. Rotary motion is now given the devices 51 to carry the tacks over the shade-roller in position to be driven into said roller when the latter and the support 25 are raised as already described. To rotate the devices 51 a ratchet wheel 77 is secured to the shaft 55, and onthe shaft is an arm 78. A pawl, Fig.

engage the teeth of the ratchetwheel, and

.the arm is rocked by a rod 79 in any desired way, there being a second pawl 80 to prevent the ratchet slipping.

The tacks will thus be deliveredindividually to the collecting device and the row. of tacks on the devices will be forced into the shade-roller by the movements of the treadle 36 so as to fasten the end of the'shade to said roller.

In operating the invention the tacks in the hoppers 57 are agitated so as to pass down the chute 56, the inturned end of each chute serving to hold and position the lowermost tack of the row. The hoppers are now moved on the shaft 59, thus throwing the lower ends of the chutes against the stops 75. This will raise the yielding member 69 of each chute and will release the lowermost tack, the remainder of the row of tacks being temporarily held by the part 76 of the stop. The hopper is now swung in the opposite direction toward the device 51 and in the path of one of the magnet arms. One arm of each device will take and hold a tack so that the chute may again be moved away from the device and the influence of the magnets. Rotary motion is now imparted to the device 51, to carry a line of tacks into the path of vertical movement of the support 25 and the shade-roller. The shade material having been forced around the roller by the fingers 4:5 as already described, the treadle 36 is depressed which will force the support 25 and shaderoller upward, thereby forcing the tacks through the material and securely fastening the end of the shade to the roller.

Where the mechanism for tacking is used separately from the shade machine proper, the tack collector may be operated directly from the treadle, and this as well as some of the other features, may be timed with respect to the movement of the work support 25.

It will be understood that the anvils or braces 43, as well as some of the other parts, may be used in connection with attaching or fastening other work than window shades; that the tacks or fastening means may be positively delivered to a tack-holding device instead of depending in part on magnetism; and that other fastening devices than tacks may be used when desired.
