GAUGING AND ASSORTING MEANS AND METHOD.

Application filed August 21, 1922, Serial No. 583,194. Renewed October 15, 1924.

To all whom it may concern:

Be it known that I, CHARLES D. KING, a citizen of the United States, residing in Rutherford, in the county of Bergen and State of New Jersey, have invented certain new and useful Improvements in Gauging and Assorting Means and Methods, of which the following is a specification.

This invention relates to improvements in means for gauging and asserting various articles such as machined or partly machined parts or blanks which require to be accurately gauged and assorted in the course of manufacture.

The main object of the invention is to provide improved means and methods whereby such parts of a permissible size can be separated from oversized and undersized parts. Another object is to provide means 20 for more rapid, accurate, and efficient separation of such parts than any other means now known to me. Other objects consist in improvements in mechanism which I term W) the gauging means of such apparatus, and

also 111 means cooperative wlth and connected withsaid means.

The means I prefer to employ to accomplish these objects, and other features of my invention not hereinbefore mentioned, are illustrated in the drawings accompanying and forming part of this specification, and in which Figure 1 is a section of my improved apparatus for gauging and assorting blanks, taken on the-line 11 of Fig. 2.

Fig. 2 is a plan of the invention.

Fig. 3 is an enlarged front elevation of the gauge and a portion of its holder.

Fig. & is a side elevationof the lower part of the apparatus, and

Fig. 5 is a plan of a portion of the apparatus under the gauge.

Like characters of reference refer to like parts in all the figures of the drawings.

In the form of my invention herein illustrated, I have designated by the letter M a portion of the mechanism which I term the blank-feeding means, another portion of the F0 mechanism which I term the gauging means I havedesignated by the letter P, and still another portion of the mechanism which I term the blank-.assorting or separating means I ve d s gnated by the letter shown, but if desired, many times this number can be employed without departing from the general principles herein disclosed- The greater the number of such means employed,

the greater will be-the capacity of the machme 1n variety'and number of blanks possible to, be worked on.

Referring now to the portion of the apparatus designated by P or the gauging means,the numeral 6 designates the gaugeholder which ordinarly is provided With a socket 7, a set-screw 8, and anti-friction rollers 9. The latter are guided in ways 10 of the upright bars 11 which form part of a frame 12 supported at the right by a portion 13 and at the left by bars 1 1 secured to the blank-chute (see Figs. 1 and 2).

The upper end of the gauge-holder 6 is connected by a link 15 to a lever 16 which is journaled by its hub 17 on a shaft 18 which shaft is suitably journaled in brackets 18. There is a second lever 16 on said shaft 18 beyond the first lever 16, and this lever 16 is connected to alink 15 and a gzfige-holder 6 movable on rollers 9 in ways 10. The levers 16, 16, have side extensions 19, 19, on which aremounted adjustable Weights 20,

20, secured by set- screws 21, 21.

In the socket 7 is secured a gauge mem ber 22, which is provided with two gauging sizes or elements as indicated on a larger scale in Fig. 3. One of these sizes is marked or and is ordinarily spoken of as the go size, and is in this instance the larger of the twoelements or sizes: The other size is marked 6 and is called the not go size.

Each of the gauge elements or sizes has two contact points that are spaced apart the stated distance ca-or b as the case may be, one of said points in each size being designated by 0 and the other by 0. The go element can pass over the diameter or other dimension of t e. part to be measure but the not go element being here less than the permissible size, cannot pass onto the part to be measured if the part is large enough to be permissible or is oversized. The gauge 22 has a shank 23 which fits the socket 7 of the holder 6 where it is held by the set-screw 8.

Secured to the shaft 18 are arms 25, 25, having pins 26, 26, extending under the levers 16, 16, respectively, and there is an arm 27 secured on said shaft which has a roll 28 movable in a slot 29 of the cam 30 secured to the power-shaft 4. The latter is driven by the motor 3 through the means of the Worm 31 on the motor shaft 32, engaging with the worm-gear 33 on the power-shaft 4. hen the motor armature revolves, the gauge-holders and gauges are given up and down movements, the former due to the direct driving of the motor and the latter due to the gravity of the weights and attached parts. I I

At the left of the gauging means is a feedchute 35, preferably with an adjustable left hand wall 36, and an adjustable front vall 37 There is a door 38 normally heldclosed by a spring39. Under the chute is a surface 40 extending to the right, and on said surface is a feed-slide 41 moved by a rod 42 connected'to a lever 43 on which is a roll 44 held in contact with the periphery of the cam 45' (securedto the camshaft 4) by the tensionof the spring 46 secured at oneend to-said'lever and at the other endto a pin in the base 2. There is a second feed-chute 35, and slide 41" and other corresponding parts to operate with the gauge 22 and gauge-holder 6.

The blank-assorting means are associated with the blank-removing means of which the first portion will now be described. Under the'gauge and'gauge-holder is a trap-door 48, secured to a shaft 50 journaled in the base 2. The said door-has a blank-seat 49' preferably as aseparate member and heldby a suitable screw 49". Thereis also an arm 51' Secured to the shaft 59 which arm is connected by a link 52 to a bell-crank 5'3 journale'd on the base 2. A spring 54 is attached atone end to the longer arm of the bell-crank and at the other to a pin in the base 2 and normally holds the trap-door 43in. its closed position. The shortarmof the bell-crank 53 is connected to a rod 55, having a roll 56 at its upper end andjoined to the frame 12 by a short link :57. As the arm25 comes near the end of' its stroke, it encounters the roll-56- and moves: it downward, thus causing the trap-door 48 to open so that a blank thereon may drop down, and the reverse movement of thearm 25 allows it to close by reason of thespr'ing 54.

Under the trap door 48' is an oscillating oh=ute 59;-norn ially' held in the position of Fig. 1 by its counterweight 60. Under the chute 59 are three receptacles 61, 62, 63, the first 61, to receive oversized blanks, the second, 62, to receive permissible blanks, and the third, 63, to receive undersized blanks. The receptacles may be provided with hottoms, or instead, moving belts such as 64 may be employed whereby the blanks dropped thereon may be conveyed away. A thrust member 65, connected to arm 66 on the oscillating chute 59 extends upward and preferably ends in a bent portion 67, and a link 68 joins it movably to the base 2. As the gauge 22 descends, its right foot portion 69 comes against the part 67 and by moving it downwards determines the position of the chute 59 and its counterweight 60.

As soon as the gauge member 22 gauges a blank, it is held in its final gaugingpost tion for such blank by means of the lockrod 70 and fork-head 71 engaging one of the pins 72 on the gauge-holder 6. The lock-rod 70 is'operated by a cam 73 on the camshaft 4, through a lever 74 having a roll 7 5 held against the cam by a coilspring 76secured at one end to-the lever and at the other to a pin in the bracket 77. The lever 74 is fulcrumedon said bracket which is mounted on a cricket 78 secured tothe base 2. The'bracket 77 also supports the lever 43 of the feed-rod'42.

There are duplicates of the trap-door 46 and its operating parts, below the gauge 22 and there are also duplicates of the chute 59 and its operating parts, together with a lock-rod 70 and itsoperating'parts similar to those for the rod 70. All the corresponding parts ar understoodto be designated by like numbers asthose parts described hereinbefore with the addition of a prime mark.

Theoperation of my improved means for gauging, and assortin'gis as follows;

A supply of blanks B is placed in the chutes 35, 35, and the machine is started by energizing the motor The worm 31 on the motor shaft 32 causes the worm-gear to revolve the power-shaft 4-, and the cams 30, 45, 45, 7 3, 73, whereupon the arms 27, 25, 25, shaft 18, and pins 26, 26, effect the raising of the levers 16, 16 weights 20, 20', gauge-holders 6, 6, andgauges 22, 22. A- so the springs 46, 46, move the slides 41, 41, by means of the levers 43, 43, and rods 42, 42, as they are permitted by the rotation of the cams 45, 45.

The slides-41, 41, on moving towards the right, take the lowermost'blank in'each chute and move them to the proper blank seats 49, 49. At this time the gauges 22, 22, are descending and reach he respective blanks immediately afterward. If the size a of the gauge is less than the size measured thereby on the blank, the gauge stops in this position, If, however, the blank is of a blanks and varies with the nature of the piece or blank. In a great many machined parts it is but a few thousandths or even ten thousandths of an inch. The difference between the size a and the size 6 may be the same amount, or it may be less than the tolerance. In the last instance, the work will be of greater accuracy than would otherwise be the case. In the drawings the sizes a and Z) are exaggerated for the sake of clearness.

If the blank being tested is too small, both sizes of the gauge will pass over it and in so doing will push down the portion 67 of the member 65 which in turn moves the chute 59 to the position where it will discharge into the receptacle 63. If the blank is of permissible size, the chute is moved to a position where it will discharge into 62, by the foot 69 pushing down on 67 about halfway. At this time the rod 70 'is moved to the left so that the forkhead 71 engages the middle pin 7 2 thus locking the gauge. The upper and lower pins 72 are respectively for usewhen the blanks gauged are under and over the permissible size. By these means the gauge is locked at the height it is in when it makes contact on the blank so that when the blank is released the gauge shall not rise and change the setting of the chute 59.

The cam 30 has now brought the levers 25, 25, to the broken line position indicated by S0. The lever 25 presses down theroll 56, rod 55, and bell-crank 53, thereby moving the link 52 and the arm 51, so that the trapdoor 48 is dropped, allowing the blank to fall into the chute 59. The chute being set as hereinbefore explained allows permissible blanks to fall into the receptacle 62, underszed blanks into the receptacle 63, and over sized blanks into the receptacle 61; The blanks fall onto the belts 64 which are preferably of rubber or leather and prevent marring of finished surfaces. The belts convey the blanks to any suitable receptacles (not shown) for final storage.

Various sizes of gauges can be used in the above-described apparatus, and new gauges can readily be inserted whenthe working gauges become sufliclently worn. Many other dimensions can be gauged by the ap-.

paratus besides the sort shown in the drawings which are illustrative of the general principe involved and not limited as to the specific gauge, or dimensions. Gauges of various types may be employed including length, thickness, internal, and other gauges ordinarily employed for inspecting work. Different dimensions on the same piece can. be gauged byusing a number of gauges, turnlng the pieces, and ad usting feed-chutes and various (parts necessary.

' By using a considerable number of feeding, gauging, and removing means in one apparatus, extending the shaft 4 and base 2, and arranging the mechanism in proper relation, a great number of blanks can be gauged and assorted in a very short time with a very small amount of attendance which may for the placing of blanks in the feed-chutes be wholly unskilled and any skilled labor required will be only at long intervals and in small amounts for keeping the machine in running order. In practice the feed-chutes will be much higher and may be provided with hoppers if desired, and may be varied so as to accommodate pieces of different sizes and shapes. The seats on the trap-doors are made removable so that seats conforming to the piece desired to be gauged can be put in place when required- If for any reason it should so happen that either the size a or the size '6 should be so near the dimension being measured on a blankas to cause the gauge to go so tightly thereon as not to fall by gravity when the trap-door 48 is lowered, there is an extractor 79 provided which is preferably pivoted on the side of the trap-door at 81 and has an overhanging portion 82 to engage with the top of the blank and is guided in a slot 83 so as to secure proper alinement on the return of the door. lhe extractor 79 moves downward on the opening of the trapdoor and the portion 82 will draw down the blank on the full opening of said door.

It is evident that the mere mechanism for giving the movements to the various parts of the above-described mechanism can be varied and any suitable towns of parts may be employed without departing from the principle and essence of the invention and I do not therefore confine myself to the details of construction here shown. Other forms of the invention may be devised and come within the scope and meaning of the appended claims.
