Definitions

• Figure 1 represents a side elevation of my improved machine
• Fig. 2 a longitudinal vertical section ofthe same
• Fig. 3 a top plan view of the 0 work-support, the indicators, and the gage.
• Fig. 4 is a view of one of the gage-plates. Fig.
• FIG. 5 illustrates a construction in which, in lieu of interchangeable gage-plates, an adjustable gage is employed.
• the letter A represents the base of the machine, having a standard, B, to which is pivoted a lever, O, that is adapted to be vibrated 0 in one direction by means of a treadle through a connecting-rod, D, and to be vibrated in the opposite direction by means of an adj ustable spring, E.
• the upper end of the lever O is connected to aplunger, F, which is guided 5 in fixed guides G G on the standard, and is formed at its lower end to receive and retain the shank of the cutting-chisel H, as shown in Fi 2.
• %pon the base A of the machine is mounted a plate, I, having a depending boss or projec- (No model.)
• I which works within an elongated slot, J, in the base, and serves to guide the plate I in its back and forth movements toward and from the standard B, but prevents any rotary or sidewise motion of said plate, and having also an upwardlyprojecting hollow post, I.
• a horizontal plate, K which is adapted to support on its forward portion a block, L, of wood or other suitable 6:) material, constituting the support for the Work and the surface for the chisel to out against.
• M is a head or stock provided with a depending cylindrical shank, which fits the bore of the post 1 so as to be capable of rotating therein, and havingahorizontal slot or guideway in its upper portion, in which works a slide, N, which carries on its outer end a segmental presser-bar, O, for holding the work down upon the block L.
• Bolted or otherwise secured to the head M is a cap, P, having vertical flanges Q Q, through screw-threaded orifices, in which passes a horizontal screw-shaft, It, supported in a block,S, upon the rear end of the slide N, so as to be capable of free rotation therein,aud having a turning wheel or crank, T, at its rear end, as shown.
• a segmental rack-bar, U having as many teeth or stops formed upon it as there are to be cut scallops 8 5 in the button-fly; and upon the rear portion of the horizontal rotatable plate K is mounted a pawl, V, which is adapted to engage successively with the teeth of said rack-bar.
• the plate K is swung around and its pawlVis dropped into engagement with the first tooth of the rack-bar, it is obvious that upon the rotation of the said plate with its work-support L and the presser-bar O resting thereon to the right, so that the pawl will engage with the 5 several teeth of the rack-bar one at a time, and rest momentarily at each tooth, the work-supports will be moved past the cutting-chisel intermittently and will make as many stops under the chisel, for permitting the operation of the latter, as there are teeth in the rack-bar, and that therefore the rack-bar will constitute a gage for determining the number of scallops to be formed by the chisel upon the work, as well as a means for properly spacing said seallops.
• the series would of course also be improperly positioned.
• I preferably employ separate indicators, which are placed one at each extremeportion of the button-flydesired to be scalloped, and serve to determine accurately theproper position of the work with respect to the chisel before the former is brought under the latter.
• These indicators consist, preferably, of two rods, WW, passing through guideopenings in the flanges 0f the cap P, and each connected at its outer end to an indicator or pointer, X, which embraces the presser-bar O,and extends slightly beyond the same, as shown in Fig. 3.
• the rods W are located on lines radiating from the center of motion of the work -support, and they are of the same number of degrees apart as would be radial lines drawn from the said center of motion of the work support through the extremes of the toothed portion of the rack-bar or gage; consequently the indicators X at the ends of the rods W, whether said rods are forced inward or outward by the adjustment of the presser-bar 0, will always indicate the extremes of movement of the work as controlled by the rack-bar or gage, and by having a care that these two indicators are placed at the extremes of the portion of the work to be scalloped and bringing the work under the chisel with the pawl in the first tooth of the rack or gage the sealloping may be proceeded with with the assurance that both the firstand last scallopswill be properly positioned and all the intermediate scallops will be properly-spaced.
• the same rack-bar, U may be employed in the scalloping of button-flies of different lengths.
• the presser-bar is adjusted. inward, thereby causing the rods W to be forced inward and their indicators 2! to slide along the presser-bar toward each other correspondingly,.this motion continuing until the indicators come opposite the points on the button-flies which constitute the extremes of the portion to be scalloped.
• the presserbar is adjusted out, thereby causing the indicators to be moved farther from eachother until the desired point upon the button-fly is reached.
• the button-flies be long or short the indicat ors can be adapted tothem, and the chisel in acting upon them will cut just as many scallops as there are teeth in the rack-bar or gage, irrespective of their length.
• the edge of the button-flies to be scalloped is not exactly concentric with the circle struck from the center of motion of the work-support, it follows that in order to secure uniformity in the scallops the work-support must be capable of a slight motion toward and from the chisel.
• the longitudinal slot J in the base A makes provision for this by permitting the plate I and all the parts carried by it to be moved backward or forward by the operator as the work proceeds and the necessity of the case demands.
• a rack-plate or gage having a greater or less number of teeth may be employed, as will be readily understood.
• I may, as shown in Fig. 5, provide the rear portion of the plate I with several series of teeth.arranged'in concentric arcs, and with the teeth of the several series varying in number, and employ in connection with an adjustable gage thus formed a. pawl mounted upon the rear portion of the horizontal plate or table K, rendered adjustable in or out, so
• a button-flyscalloping machine the combination of a rotatable support for the work, a gage for regulating the number of times the support is to be arrested in its rotary movement and the consequent number of scallops that are to be formed in the work, and indicators located on lines radiating from the center of motion of the work-support and of the same number of degrees apart as are the extremities of the regulating-gage,whereby by placing the extremities of the portion to be scalloped beneath the indicators the proper disposition of the scallops is insured, substantially as described.
• buttons-flyscalloping machine the combination of a rotatable support for the work, a gage for regulating the number of times the support is to be arrested, indicators adjustable on lines radiating from the center of motion of the work-support and of the same number of degrees apart as arethe extremities of the regulating-gage, and means, substantially as described, for securing said indicators in adjusted position, whereby button flies of different lengths are enabled to be scalloped 3 5 with their scallops properly disposed, substantially as described.
