5 New York, have invented certain new and useful Improvements in Engraving-Machines, of which the following is a full, clear, and exact description.

This invention relates to engraving machines and more particularly to those machines which are used for engraving graduations on gun sights, scales and the like.

(has object of the invention is to provide ting or adjusting the work for different engraving positions so arranged with respect to the work that any inaccuracies in the setting or adjustments will appear only in diminished amount in the work itself.

Another object is to provide simple and efiicient means for imparting to the tool, in addition to its engraving movement, a movement into and out of engagement with the work at the proper time', and means for auton'iatically and variably limiting the extent of the engraving movement according to a predetermined plan.

Qther objects of the invention will hereinafter appear, and the novel features thereof will be set forth in the claims.

Fig. 11 is a section on the line 11- -11 of Fig. 9.

in a machine of this kind, means for set Fig. 12 is a section on the line 1 12 of Fig. 9.

In carrying out the invention, 1 provide an eccentrically pivoted carrier, on the short arm of which the work is supported, and means acting on the long arm of the carrier for moving it and the work carried thereby to different engraving positions, and for holding the same in such positions during the engraving operation.

In the embodiment illustrated there is provided a table 11 properly supported by the

standards

12 and 13. At the front of the table 11 there is provided the laterally extending platform 14, having two pairs of arcuate rows of orifices 15 and 16, for cooperating with the

pins

17 and 18 mounted in the head 19 at the end of the long arm 20 of the work carrier a, which is pivotally mounted in the bearing 21 with its short arm 22 provided with a seat 23 for receiving the work 24: to be operated upon, whereby the successive operating positions of the work carrier are accurately determined.

The engraving tool 25 is mounted to reciprocate relative to the standard 26 which is fixed to the rear portion of the table 11 rearwardly of the path of movement of the work receiving end of the work carrier at.

For facilitating the oscillation of the long arm 20, the rollers 27 are provided, the axes of which coincide with the lines radiating from the axial center of said arm 20. At the far ends of the platform 14: are formed steps 28 which cooperate with the rollers 27 to limit the movement of the arm 20.

The

pins

17 and 18 are secured by suitable bearing'blocks 28-28 to the upwardly extending

arms

29, 29 pivotally connectedto the lever 30, which is adjustably mounted on the shaft 31. The shaft 31 is carried at its front end in the bearing 82 formed on the arm 20, additionally supported by the intermediate bearings 38, 3 1, and supported at its rear end in the bearing 35, to the rear of which the operating handle 36 is fixedly located on said shaft 31. To alternately register with the orifices 15 there are provided the pin guiding thimbles or

thimble guides

37, 38, and to alternately register with the orifices 16, there are provided like thimble guides 89, 40 formed on the arm 20. The manipulation of the pins is substantially as follows: Assume that the lever 30, as shown, is set so that the

pins

17 and 18 reciprocate in the

guides

39, 10, then upon the guide 39 or 40 registering with an orifice 16, the proper manipulation by the handle 36 will swing either the

17 or 18 into an orifice 16. Since the spaces between the orifices 16 vary from very short spaces at the top of Fig. 2 to comparatively long spaces at the bottom of said figure, it has been found desirable to actuate the arm'20 from one to another of such orifices 16 by means of the block and tackle arrangement 11, in whicha cable42 is fixed at one end to the arm 20, is wound around the sheaves l3 and 1 1 connected to the platform 14: and arm 20, respectively, and then to the sheave 45 formed on the side of the wheel 46. When the lever is mounted on the shaft 31 so that its

pins

17 and 18 register with the

guides

37 and 38, then the orifices 15 will be engaged. Since the orifices 15 are disposed relatively close to one another and the spaces between them uniform, it has been found desirable to so arrange the oscillation of the shaft 31 that successive orifices can be engaged alternately by the

pins

17 and 18 by merely swinging the lever 36 from side to side as the need arises. The

pins

17 and 18 are provided with the cam faces 103 along their ends, which cotiperate with the orifices to advance the work carrier a. When the pins cooperate with the orifices 15then the cam faces 103 will be solely depended upon for advancing the carrier. When the pins coi perate with the orifices 16, then these'cam facesserve to facilitatethe ready engagement of the orifices by said p1ns;-

The bearing 21 on which the carrier a is mounted is adapted to facilitate accurate alinement of such carrier relative to its appurtenant parts, and since it forms no part g ofthe present invention the following brief boss from said shank 17.

description will suffice. This bearing comprises an enlarged cylindrical boss, having a shank 47 extending down from the center 7 thereof, around which shank a? in said boss 16 there is formed an annular groove 48 to space the annular bearing face 19 of the On the table .11 there is secured a bearing 50 which incloses a split bushing 51 drawn-tightly against the shank 47. To the lower face of the table 11 there is secured-a bearing bracket 52 which incloses a split bushing 53 similar to the bushing 51 which is also tightly drawn against the shank 1-7. The lower end of the shank a7 is threaded and has lock nuts 54 secured thereto to lock the shank in place. The work occupying end of the short arm 22 is mounted to travel on the smooth faced hearing 55 and has an arcuate rear face in which the sharp ti-shaped seat 23 is formed to receive the work 2 1 which conforms thereto,

To anchor the workin the seat 23 the locking 7 plates 56 are prov1ded,which engage the rear upper edge of the work 24: and upper face of the work supporting arm 88, and aresecured in place by the screws 57.

The work 24 illustrating a range scale,'and for engraving which the machine is especially adapted, embraces an arcuate metal strip having a medial groove 58 extending throughout the same, the upper zone 59 0f which, see Fig. 7, is cut with graduations, the distances between which vary from the shortest at the lower end of Fig. 7 to the widest at the upper end of such figure, and the lower zone 60 of which is cut with graduations that are uniformly spaced from one another. The varying graduations are designated meter graduations and the uniform gradu'ations' are designated mill graduations by the range finder and are generally marked \ftr. and Md, respectively. Since the invention confines itself to means for engraving the graduations, the use of these scales will not be gone into.

The engraving tool and its appurtenant parts which form an important part of the present invention will now be described. Rearwardly of the short arm 22 and on the table 11 there is formed the standard 26, from one side of which extends the arm 60', having formed in its end face the dove-tail groove 61 to receive the dovetail 62 of the block 63, such block 63 being secured to the arm 60 in said dove-tail slot by the set screw ea. In the block 63 there is journaled the stub shaft 65 on which is rotatably mounted the gear 66, to which is fixed the operating lever 67. Also loosely mounted on said stub shaft 65 is a stop wheel 68, on the periphery of which, and radially extending theref om, there are provided a plurality of stop pins 69 adjustably mounted to extend different distances from such periphery. Adjacent to said stop wheel 68 and fixed thereto is provided the notched disk 70 wvhich is adapted to coiiperate with the pawl 71 secured to the lever 67. r V

Adjacent to the stub shaft 65 there is formed an elongated slideway 72 in the block 63, in which is slidably mounted the slide block 73, on the upper end of which is mounted the tool supporting bracket 74, and along the sides of which are mounted the rack 75 and stop cotiperating bracket-76.

.The rack 7 5meshes with the gear 66 and thus when the handle 67 is rocked, the gear 66 will actuate the rack 75 to in turn actuate the bracket 7 1. The stop coiiperating bracket 76 has an arm 77 provided with a stop face 78 for alinin'g with and engaging one of the stop pins 69 of the stop wheel,

1n the upper portion of the bracket7e there is formed a slideway 7 9 to receive the V slide piece 80 in the groove 81 on which the engraving tool '25 is adjustahly mounted; The" rear end of the slide piece 80 is pivotally connected to the link 83 which is pivotally connected o the perforated link 84 which is pivoted to the rear end of the bracket 74. In the link 84 are provided two adjacent orifices or

perforations

85 and 86. The bracket 74, which extends both above and below the link St, is provided with one set of

alined openings

87 and 88 to register at one time with the orifice 85, and another set of

alined openings

89 and 90, to register at another time with the orifice 86. On the sides of the bracket 74; adjacent to the link 8+1; there are formed the

ears

91 and 92, having parallel openings therein to receive the parallel rods 93 and 9 1 respectively, of the frame 95. The rods 93 and 94: are connected at their upper ends to the cross piece 90 disposed above the bracket 7% and at their lower ends to the cross piece 97 below the bracket 74. Secured to and extending downwardlyfrom the cross piece 96 there is provided the pin 98 which is adapted to register with the

orifices

87, 8 5 and 88 and has a cammed end 99, the point of which is dis posed along the face of such pin which lies adjacent the

orifices

89 and 90. Secured to and extending upwardly from the cross piece 97 there is provided a pin 100 which is adapted to register with the

orifices

89, 86 and 90 and has a cammed end 101, the point of which is disposed along the face of such pin which lies adjacent to the

orifices

87 and 88. The cross piece 97 in addition is normally connected to the lever 67 by the link 102.

The operation of the engraving tool is substantially as follows: Assuming that the upper scale 59 is to be cut, the stops 69 would be adjusted according to the depth of the several cuts to be made thereupon, the stop cooperating bracket 77 adjusted, and upon the upward movement of the lever 67,-the links 83 and 84: being so timed that when the tool passes beyond the lower zone 69, the pin 98 will be moving out of the orifice 85 and the pin 100 enteringthe orifire S6,the inclined face of the point 101 will serve to cam the link 84 over, and thereby thrust the link 83 forward to in turn move the tool 25 into engagement with the zone 59. Upon the downward movement of the lever 67, the tool 25 will be withdrawn out of engraving engagement as soon as it reaches the groove 58, at which time .the pin 100 will again release the link 84 and the pin 98 returned into engagement with such link 8&. p

When it is desired to engravethe lower zone 60, the frame 95 will be disconnected from the lever 67 and the stop pin 69 and stop bracket 77 solely depended upon to limit the engraving action to the lower zone, to the exclusion of the upper zone.

It is obvious that various changes and modifications may be made to the details of construction without departing from the general spirit of the invention.
