The tracer tool and the operating tool are mounted. in. sutabieldeeices, these devices being interchangeable, that is, either of the todlscan'be' plfed on the lrrh that projects most or the one that projects least from f the head or support. In the form Ishown the tracer tool 46 is shown in the outermost position, being mounted so that it is vertically adjustable in a device 4:7, being` held in position by a setscrevv 48 passingthough the body portion ofthe device it?` thetoolholder or device 47 bein slidabl by teastntta dote-'tailed Slidey eending'n they groove 50 of the end 3,9, 'and being"A held in its various horizontally adjusted positions by; a" lsuitabie'ysetjsere t 51, and the operating' tool is mountedlin a device or holder 52 which has an extension 53 that tits in a `dove-tailed groove 54 in vthe end 38 and is `held in adjusted position by a set scelw 55. `A spindle 56 is adapted to carry the nperatingtool 57 in a suitable chuck or by any other means, and is provided at its upper end with means for attachin it to a flexible shaft 58 and is also prefera ly Vprovided with a momentum head 59 that insures its steadyo eration.y

To provi elor the disengagement, if desired', of the operating tool from the Work onvvhjoli it 'soperatttng the spindleyis made verticallylrnovatblein its holding de vice 52 `and is provided With a collar 60 wlrleh is" connected by pins in the fork 61, which ispivoted` at'62 to the frame and has alliandle't'thereon so 'as tograise fit up by'pressihg onthe handle.

It Will be evident that if the handle 32 is turned and the

arms

22 and 23 are not locked against movement, these arms Will be slid so as to project more or less from the head, and if the pinions operating these arms are of different sizes, their ratio will determine the ratio of movement of these arms.

If the machine is to be used manually, one of the handles is swung out to the dotted position shown in Fig. 2, and the device is grasped much in the same way as a carpenter Would grasp a jack plane, the handle being grasped by the right hand, the tool end of the device being guided by the left hand, and by a back and forth movement or swinging movement, as desired, the tracer tool and the operating tool can be made to move in any desired direction, the ratio of their movement being defined by the ratio of the

pinions

27 and 28 one to the other.

If a reproduction is to be made smaller than the pattern, the operating tool is put at the innermost position and the tracer tool at the outermost position, and if a reproduction is to be larger than the pattern, the tracer tool is put at the innermost position and the operating tool at the outermost position.

Another Way of using the device is to fasten the pattern and the wor k in position and then operate the device from the tracer tool, guiding it in the desired direction, or in case a pattern of Well defined outline is to be followed, simply placing this tracer tool on the pattern.

In Fig. 5 I illustrate a pattern 74, the tracer tool 46 being shown in various positions therein, and corresponding positions of the operating tool 5T are shown on the smaller reproduction made thereby. Assuming that this is a groove that is to be routed in a piece of material, the tracer tool., following the groove in the pattern, causes a corresponding but smaller reproduction by the operating tool. The upward movement of the tracer tool causes a corresponding upward movement of the operation tool by reason of the strip 69 being raised when the tool holder 4T is raised, the strip 69 in turn raising the tool holder 52, these parts returning by gravity to their positions, this gravitation being assisted usually by the fact that the strip 69 is made of yielding or spring material. When it is desired to make straight parallel reproductions, the rotatable head can be placed in the proper position, locked by the latch 17, and then straight sliding movement of the

arms

22 and 23 results in similar movement by the tracer tool and the operating tool.

In Fig. 6 I illustrate a means for regulating or controlling the feeding of the arms when such Feeding should be very gradual, such, for instance. as when a very fine tool is traversing a tine piece of Work, on each traverse the tool is advanced but a very slight distance. One means of controlling this is illustrated in Fig. 6, in which the bracket 76 is mounted on a swinging element, such as the plate 7T, which is pivoted at T8 and the device can thus be swung into and out of operative position. The bracket conA tains a shaft 76a which has on the top thereof a hand piece 79 by means of which it can be turned, the hand piece being adapted to be held against accidental movement by suitable means, such as the strip #52, which has a slight projection, and the strip 82 being made of spring material, it snaps into the serrations or grooves in the edge of the hand piece 79 and holds the hand piece against: accidental movement. lV hen, however, the tool is to be advanced, the hand piece T9 is turned and the worm 8l on the shaft T6 en gages the worm gear Si), which is provided on the edge of the wheel 32, and a vvery slight advance of the bar carrying the tool is thus provided for.

Other means of insuring such gradual advancement can be provided, so long as it makes it unnecessary for the operator to attend to the tedious slight advance `for each time the tool traverses the Work laterally.
