through our improved means for control-i linlIg the supply of air to the fixture.
Throughout'the several views, similar reference characters willb'e used for referring to similar parts. c i7 Referring for thepresent, to Figures 'l to 4; inclusive, wherein we have shown our invention in connection with a milling machine of well-known construction, the reference character 10 indicates a turn-table which is rotatably mounted on the inverted cone bearing 11 and is'driven by a worm,
(not shown), through the worm gear 12 secured to. the flange 13 of the turn-table in a" well-known manner. The reference character 14 indicates the head of the ram 15, both of which are reci procably mounted in the ram guides 16, one side only of which is shown. I
Bolted, or otherwise secured to the turn-' table are a pair of fiXtures 17 and18, each comprising a face plate 19, and an arbor or.
one end of which is pivotally secured to the free end of the lever 24, and the opposite end of which is provided with a piston 26, reciprocably mounted in the cylinder 27 It will be clear from the above description, that when the piston 26 is forced upwardly, the flange 28 of the work will be clamped against the face plate 21 and that when the piston-26B forced downwardly the dog 22- thecolumnj31 having the flange 32 at its lower end which may be bolted or otherwise secured to the turn-table.
Referring to Figure 5, it will be seen that the'distributor block is provided with a central tapered valve seat 33 in which is seated the tapered-plug 34 which is held on itsseat the compression spring 35 and the follower 36.: Since the distributor block 30 7 is to rotate about the valve 34, thedistributor block is secured to the turn-table in'such a manner that the valve seat willbe coaxial with the turn-table. For holding the valve'34. stationary,'we provide a lever 37, one, end of which secured to the stem'38 of the valve 34 and the otherend of which rests against the lower ram guide or arm as shown in Figure 1. From this description, it will 'be clearithat if the turn-table isrotated in a clockwise direction, the free end of the lever will be constantly maintainedin contact with the ram arm and the valve34 will be held stationary.
The valve 34 is provided with an air inlet passageway 39 shown in dotted outlinein Figure 5, which is adapted to be connected with an air supply pipe 40 as shown, in Figure 1, which may be supported by a bracket 41, secured to the ram arzni-Tw'o ports 42 andv43 formed in the valve 34,- radially and in opposite direction from each other, communicate at their inner ends with the inlet passageway 39. The outer ends of the ports 42 and 43 comprise annular grooves 42-and 43-.1espectively,.formed in the outer periphery, of the valve 84. On the opposite side of the valve fromthegrooves 42' and 43 are formed the annuar grooves 44 and 45, respectively, the groove 44 communicating with the atmosphere through the longitudinally extending groove 44' and the groove 45 communicating with the atmosphere through the groove 45. (See Figure 8.)
This last mentioned groove extends from the groove '45 to the lower end of the valve 34. The grooves 44 and 45 form means for venting the cylinders 27 in a manner which will presently be described,
Two pairs of ducts 4647 and 4849 are formed in the distributor block 30, and the inner ends of the ducts 46 and 48 lying in the plane of the grooves 42" and 44 and the In a similar manner, the valve 53 is provided with .the transverse ducts '56 and 57 forming a connecting means between the interrupted portions of the ducts 48-49, and providing a continuous passageway from the valve seat 33 to the outside of the distributor block. 3 i
The valves side with the two grooves 60 and 61 (see the left handside of Figure 5) and onthe other side with the groove62. (See the right hand side of Figure The groove 60 extends from a point slightly below the duct 46 to the end of the valve. and thus forms a vent to the atmosphere. The two grooves 61 and 62 are connected by a transverse duct 63 extending through the valve. It will, therefore, be seen than when the valveis turned to the position shown in Figure 6, it connects the inner portion of one of the upper ducts with the outer portion of oneofthe lower later on, the ifiow of air-to andyfrom the 51 and 53 are provided on one ducts, thereby' reversing, as will be described 7 cylinders. The valves 53 are held on their seats by the compression springs 65 and the followers 66. The upper ends of fthe stems 67. 1? the valves are provided with handles 68 by means of which the valves can be turned in their seats. It'will be noted that there is a space between 'all three of the valve stems and their followers, thereby providing means for permitting the escape of air from the vents 44' and .60.
Two pipes 70 and 71 respectively, connect the ducts 46and 47 with the upper and lower ends respectively of the cylinder 27 shown in the lower side of Figure 2 and two other ducts 72- and 73 respectively connect the ducts 48 and 49 respectively with the upper andlower ends of the cylinder 27 shown at the upper side of Figure 2. a
With the distributor block. and the valves in the position shown in Figure 5, air will enter the passageway 39 through the pipe 40 and part of the air will pass through the port 42, groove 42, ducts 48 and 56 and pipe 7 2 to the upper end of the cylinder 27 shown in the upper side of Figure 2 thereby ISO 7 munication with the grooves 44 and 43!, re-
forcing the piston in this cylinder downwardly and moving the dog 22 to its release. position therebypermitting the workman to place the work on'the mandrel 20,-, At the same time, air will pass throughthe passage- 7 way '39, port'4e'3, groove 43', ducts 47 and and pipe 71 to the lower end of the cylinder 27 shown at thelower side of' Fi re 2, thereby forcing the piston 26 upward y and actuating the dog 22 t hold the work on the chuck.
As the piston in the first mentioned cylin-o der' moves downwardly, the airinthe lower side-.of the cylinder will be displaced.
nections above described areiillustrated in Figures 7 and 8.- c a r f the turn table is then rotated, the ducts 4:6 and 47 'will beplaced 'into communication with the grooves 42' and 45,-respectively and the ducts48vand 49- will be placed: into comspectively, it-hereby reversing the connections to the two cylinders and causing the,
pistons therein to move in directions opposite to those in which they previously moved,
thus releasing the'finished work and clamp-; ing the new piece of Work onto the mandrel.
brought into cutting position by the rotation of the turn-table. 1 r a .It may sometimes, happen that the operator will desire torelease'orclamp the workon any given fixtureflindependently of the operation ofthese devices'as determined by the valvel34 and for this purposewe have provided the two valves'5lwand 53.
Considering for the time being the valve at the left hand side of Figure 5, it will be noted that when the valve is in; the position shown therein, air under pressure is transm ttedto thelower side of the cylinder 27 and air is ventedsfrom the upper side of thecylinder. If the valve is then turned to the position shown in Figure 6, air underpressure will be conducted to the lower side of cylinder will be vented, thereby reversing; the operation of the fixture, Either valve 51 or 53 can thus beused for reversing the the cylinder and the operator is thereby pro-.
