The machine comprises a pair of spaced frames 1 each having a rearward upstanding extension 2, said extensions spaced apart to receive therebetween substantially all of the head operating mechanism, and making for compactness, see Figure 4. Mounted upon the frames is a table 5 which is of greater length than the distance between the frame members and the arms 2. Upon this table is mounted a buck 6. A rockable element 10 is pivotally mounted between and upon the arms 2 y means ot a rod 11. rlhe element 10 thus has the general form of a lever intermediately pivoted, and on one side of its pivot has a presser head 12, and on the other side a rotatably mounted flywheel 13 of sufficient weight to counter-balance the head 12. The wheel is composed of two spaced disklike elements mounted upon a common support or shaft 14 to move in unison. This shaftis held at opposite ends in spaced arms 15 of the element 10. A connection for limiting flywheel rotation, in this instance, comprises a pivoted link 16 having one end pivoted as at 17 to the flywheel between the disks, see Figure 4. The opposite end of the link is pivoted to a bar or rod 18 supported at opposite ends by and between the arms 2 or, as shown, by extensions 19 of these arms. As shown in Figure 1, the arrangement of the pivoted link is such that its pivotal points, and the rotative aXis of the flywheel are substantially aligned during the pressing operation and w en thus aligned function to lock the head in pressing position. The arrangement thus far described is substantially similar to that disclosed in my Patent, Number 1,562,837 of November 24, 1925, and, therefore, a press is provided having a pressing head mounted for movement to and from pressing position, along with means for locking the head in pressing position. rIhis means includes the flywheel and means connected therewith whereby when the wheel is set in motion the same will thereafter expend its kinetic energy in assisting to complete the pressing movement of the head, and when operated inreverse direction will retract the head. In the patent above referred to, the device is manually operable by raising or lowering the head.

One of the features of the present invention is the automatic operation of the device by means, for example, of compressed air. ln this instance there are separately controllable fluid-operable elements, respectively for advancing and retracting the head. The details of construction are claimed. However, it will be understood that the invention is considered broader than such details, although the machine as illustrated represents the commercial form at present found most satisfactory.

For the purpose of operatingthe mechanism to advance the head, a piston cylinder 20 is pivotally mounted by one end upon the rod 1 8, and therefore is pivotally mounted co-axially with the lower pivotal point of the link -16. The cylinder lies between the arms 2 and extends generally in an upward direction. The piston of the cylinder is pivotally connected by a rod 21 to the rear portion of the rocker 10, as at 22. Figure 1 shows the piston in the position it assumes during the pressing operation. The position which it assumes when the head is fully raised or retracted is illustrated in Figure 3, and it will be understood that upon admission of air when thus positioned, the rear portion of the rocker 10 will act to rotate the flywheel in direction of the arrow about the pivotal point of the link 16 with the flywheel as center. A4s the result of this action, the flywheelwill move to the position shown in Figure 1 in which the head is forcibly held and locked in pressing position because of the substantially aligned relation of the pivotal points 14, 17 and 18.

ln order to reverse the motion of the flywheel a stop 24 is provided thereon, and when the wheel is at that limit position shown in Figure 1, this stop is disposed for engagement with oris engaged with the arm 25 of a bellcrank lever, the other arm 26 of which is connected by a piston rod 27 with a piston 28 slidable in the cylinder 29. The cylinder is pivoted at 30 beneath the table 5. The element 29 may be referred to as a release cylinder, and when air is forced thereinto the wheel 13 is given an initial movement substantially illustrated in Figure 2 to cause the flywheel to move in reverse direction to that limit position shown in Figure 3. lt will be noted that the bellcrank lever is pivoted to the rod 11 and therefore concentrically with the pivot of the head or rocker arm 10.

A cushion stop 30a is carried by the presser arm and is arranged to be engaged by corresponding stops 31-32 carried by the flywheel. rFhese stops merely act to yieldably limit rotation of the flywheel in opposite directions.

Means for locking or latching the pressing mechanism with the head in fully retracted position is provided. This is a feature of the invention which prevents advance of the head unless both hands of the operator are in such a position that there is no possibility of injury due to accidental insertion between the buck and the head.

Referring to Figures 3 and 4, a rod 35 is pivoted as at 36, to the rear arm of the rockable presser head frame. Slidably adjustable on this rod is a stop 37 held in adjusted position by a set screw 38. The stop is engageable with a corresponding abutment or stop 39 of the frame, and when the stops are engaged as shown in Figure 3, the head cannot be lowered. In order to release the stop 37, a latch 40 is pivoted as at 41 to the frame. The latch has a forward extension having an opening 42 therein and, the arrangement is such that, when the stops are engaged as shown in Figure 3, the rod engages what Imay be considered the rear side 45 of the opening while at the opposite side play is provided so that the rod may rock about its pivot in direction of the arrows A. The latch occupies the position shown in Figure 3 except when operated by the button 46 for-ming part of a bellcrank lever pivoted at 47 at the outreeafiia er edge of the table and adjacent but below the buck 6. Une arm of this lever is adapted t0 be engaged by the hand and depressed, and the other arm has pivoted thereto as at 48, a connecting rod 49 pivoted as at 50 to the latch. When the lever or button 46 is depressed the latch moves the rod in direction of the full line arrow A to release the j latch. A suitable spring, not shown, tends always to return the latch mechanism to the position shown in Figure 3. After release of the stop 37, and as the head is lowered, the rod is raised. When the head recedes and the rod moves in the opposite direction the elongated opening 42 permits the rod tov ing position.

This latch mechanism in combination with the air control is a feature of this' invention which provides the features before mentioned. The air control valves are mounted upon the forward edge of the table as best shown in Figures 6 and 7 and the arrangement is such that the air control and latch device must be substantially simultaneously operated, one by each hand. Tn this way both hands will be occupied with the control and therefore' will not bevpositioned for injury by the presser head.

The air supply, and control means, including the supply tank and valves for respectively controlling the air to respective cylinders are features of the invention. This mechanism is a feature of the lnventlon. This air control means is mounted upon the table- 5,'in this instance at the front edge adjacent but forwardly of the buck but at a level therebelow. The tab-le 5 is provided with horizontal extensions 50, see Figure 6, between which are pivoted a pair of arms respectively 5152 both of which are for controlling ad-` a valve to admit air to the cylinder 29 of the other machine tov release and cause the head to rise. levers and corresponding valves are provided in alll machines in anticipation of this tandem connection. However, it will be further un- It will be understood that the two ggg derstood that onlyone valve-control lever is necessary to admit air to the cylinder 29.

Fach of these release-cylinder control levers is provided with a button 53 arranged as best shown in Figure 9, and the upward movement of this button is limited by a stop screw 54. For convenience, the buttons are considered as part of the levers, and in some of the igures are given the same reference letters as the levers. The valve mechanisms operated by the levers are identical, and the description of one will therefore answer for the other. Referring to Figure 9 which is a section on lines 9-9 of Figures 6 and 7, the lever is pivoted-as at 55 between the arms 50, and rests against the upper end of a valve stem 56, the lower end of which engages a valve 57 to depress it against the action of the spring 58. The stem 56 loosely traverses a passage 59, which communicates with a cross passage 60 leading to pipe 61, the outer end of which pipe 61, is branched as at 62-63, see Figures 6 and 7. One of the branches 63 is connected with a release pipe 64 of the other machine, (when the machines are used in tandem, see Figure 12) by a pipe 65. One of these pipes is designated 65, and the other 65a. When the machines are not used in tandem, branch 63 is suitably closed by a cap 65h, indicated indotte-d lines in Figure 6. The connection between the other branch 62 of the pipe 61 and therelease cylinder` 29 is made by means of a flexible connection 67. Moreover, when the machines are not used in tandem pipe 64 is also capped as indicated at 68, see Figure 6. Tn this latter case, only one release valve-control lever 51 is used. The operation of the machines when in tandem will be described along with the description of the valve operation of a single machine.

The valve for controlling air to the cylinder 20 is best shown in Figure 10. The valve stem is indicated at and a valve-cap at 71.

Tn this instance the upper end of the valve 4 stem 7 O engages the cap 71, which has exhaust ports 72, see also Figurey 8. Referring to Figures 6 and 8, a U-shaped framelike lever 73 having a thumb piece 74, is pivoted at 75 at the outer side of the arms 50.4 The' lever extends beneath the table, and the thumb piece is arranged at the edge of the table. This lever has a lateral extension 76 engageable with the valve cap 71 to depress the cap and stem to open valve78, as best shown in Figures 8 and 10. The valve 78 opens against the action of the spring 77. The stem 70 loosely traverses the passage 79 which passage communicates with a passage 80, see Figure 8. This passage 80 leads into a pipe 81 which is flexibly connected by means of the pipe or'hose 82 with cylinder 20.

The valve cap 71 is for the purpose of peri mitting escape of air from the cylinder due ythe result of the rising motion of the head.

lto the downward motion of the piston as Referring to Figure 8, it will be seen that air forced through pipe 81 by the piston of the cylinder 20, will flow through passages 80-7 9 to escape through openings 72. Vhen the lever 73 is depressed to operate the valve 78, the openings 72 are closed, so that the piston of cylinder 2O is submitted to full pressure.

Air is supplied to all three valves by what may be termed a manifold, see Figures 8, 9 and 10. This manifold comprises in parta block 90 suitably formed to support the valve operating springs 58 and 77 and to supply passages for the conduction of fluid to all of the valves. This block 90 is suitably detach ably connected to the valve casing 97 and a washer 96 is interposed between these elements and is supplied with openings 98 for establishing communication rbetween the chambers of the manifold and the valves 57 78 and passages controlled thereby. The manifold also has a bore 91 having a screen thereacross as a Iilter. A screen is held in place by`a block 93 having a nipple 94, connected by a supply line 95 with an air supply tank 96. The nipple 94 communicates through the screen with the passage 91 of the manifold. .lt will be evident that fluid supplied through the pipe 94 will be distributed to all the valves.

The relief for the cylinder 29 is obtained by a small opening 99, see Figure 2, so arranged as to permit exhaust of air only after the flywheel 13 has been kicked to release position. A certain amount of leakage is also 'provided at 100, (see Figures 9 and 10) around the stems 56. 1t will be understood, however, that when the air is admitted to operate the release-cylinder, the leakage is not suicient to prevent proper action to kick the wheel to release position.

Vith the machines arranged in tandem, as shown in Figure 12, let it be supposed that the machine at the left of the figure has its head in pressing position. Let it further be supposed that the operator is arranging an article upon the buck of the machine at the right of the figure. After the article is arranged, buttons 74 and 46 are depressed, and the head is lowered to pressing position. Tf While the operator is standing at the right hand machine it becomes necessary to release the pressing head of the machine at the left, this can be done by depressing button 52 of the right hand machine, whereby air is admitted through pipes 64, 65, 63, 62, 67 to release cylinder 29, and thev presser head will be raised. On the other hand, if the 0perator is standing at the machine on the left of the ligure and wishes to raise the head of themachine at the right, button 52 is depressed and air is admitted for operating the cylinder 29, through pipes 64, a, 63, 62 and 67.

It will be understood from previous explanation that when only a single machine is recaen;

used the pipes 63-64 are capped and then lever 51 only is used, to obtain operation of the cylinder 29.

ln the operation the parts are initially disposed substantially as shown in Figure 3 with the head locked, by the latching mechanism in its upper position. The article to be pressed is placed upon the buck and respective thumbs are engaged with buttons 46-7 4 and both are depressed substantially simultaneously resulting in release of the latch mechanism, and admission of air to the cylinder 20. By this means the flywheel is moved from the position shows in Figure 3 to that shown in Figure 1, thus disposing the projection 24 in position to be engaged by arm 25. latch 38 will lie above its companion abutment 39. However, inasmuch as the rod 35 can swing about its pivot 36 in direction of the full line arrow A, the latching engagement will be automatically again made when the head again reaches the position shown in Figure 3.

.Vith the machine in pressing position shown in Figure 1 and after the proper interval, lever 51, for example, is depressed and air is admitted to the cylinder 29. The result is substantially shown in Figure 2 which shows that the flywheel has received a kick to give it sufficient momentum to carry to the position shown in Figure 3. As the piston 28 travels outwardly the air in the cylinder 29 .escapes through the opening 99 and also through the bore 100.

The arrangement whereby the momentum of the flywheel is taken advantage of to o erate the head makes the application of fluidoperable means for this purpose particularly economical. This because the air or fluid is only used momentarily. That this is so is evident from the fact that a mere initial kick only is necessary for supplying suliicient momentum to the wheel for either advancing the head to pressing position, or retracting the same from that position. i

Another advantage is the compact arrangement of the head operating mechanism including the air controlled means. Another advantage is found in the mechanical latching mechanism which prevents fluid operation of the head when the hands of the operator are positioned to be injured by pressure cooperation between the head and the buck.
