To all whom it may concern:

Be it known that 1, Crimes BnAnLnr,

a citizen of the United States, residing at Los Angeles in the county of Los eles and State of California, have invented certain new and useful Improvements in Delivery Heaters for Printing Presses, of which the following is a specification. This invention is a heater for the printof the invention to automatically shut-01f the heater when the press is tripped, and to 3 gain supply the heat as soon as thetrip 1S released.

The heater is particularly adapted for atwo-revolution cylinder press. operating of the object of the invention to provide a heater which may be removably mounted on the carriage of the sheet delivery mechanism, and having a control ada ted to be turned on and ed by operation o the fountain trip ress.

Furt or objects of the invention will be readily derstood from the following desclllipfiion of the accompanying drawings in w 10 Fig. l is a perspective view of the de-' livery mechanism of a press, showing the heater mounted. thereon.

,. is a side elevation of the heater control mechanism, showing the same when the trip of the press is released. Fig. 3 is a similar view showing the position of the parts when the. press is tripped.

1 1g. 4 is a vertical section on the line 4-4: of Fig. 2.

Fig. '5 is a perspective view of the heater.

I have shown the heater 'mounted. jipon a standard two-revolution cylinder press, the heater being supported by the fly stick rod of the delivery mechanism so as to heat the printed sheets as they pass to the jogger board of the press. The heater is shown as a gas-burner pipe extending the width of the delivery carriage, and having a valvular control which is operatedv by a cam mechanism fixed to the fountain trip connecting rod of the press.

A usual delivery mechanism for a press is shown as comprising delivery ways 1 with carriage 2 adapted to move back afid gear side of the forth thereon, the carriage being operated by usual 5 levers 3 and link connections 4. Rod 5 of the carriage supports the fly sticks 6, to. which the printed sheets are delivered faceup from the tapes 7 asthe fly sticks move-outwardly toward the jogger board 8 of the press.

S top fingers 9 mounted on a rod 10 of 'to permit delivery thereof to said board .the carriage hold the printed sheets on the ed sheets from a press, and 1t 15 the ob]ect.

by the action of pusher fingers 11 as the carriage moves inwardly. The pusher fingers'are mounted in usual manner upon a transverse rod'll of the delivery carriage.

The fountain box 12 is mounted'below the jogger board, andthe fountainratchet lever 13? is operated in usual manner by the connecting rod 13 which extends along the gear side of the press. The fountain trip is operated by cam 14 which is connected to, trip rod 15 extending ,alongthe press; and depression of the usual foot pedal (not shown) .isadapted to trip the press in usual manner to allow reciprocation'of the bed without contact of the printing form with the cylinder and also shift rod 15 to operate the fountain trip. Rod 15 is also depressed as it. is shifted longitudinally, due to the limited movement of the arm 14C of the .tri earn from the position shown in Fig. 2 to that shown in Fig. 3. p

The improved heater for the sheetdelivery is shown as a pipe 16 removably supported by brackets 17 from fly'stick' rod 5, and extending the width of the press in frontof said rod. Gas is preferably used as a heating medium, the. pipe 16 being provided with burner apertures 18 along its outer side; and a shield 01' baflie' strip 19 preferably extends over the top of pipe 16 in spaced relationabove the burners to protect the printed sheets and also prevent exsite or gear side of the press through a pipe connection 21. The pi e connection-extends v upwardly over the delivery wa 1 and carriage 2, and along the outer si e of the dea pipe-16 at the feeder side of livery way, so as to ermit movement of the heater with the de ivery carriage without striking the stationary parts of the press. The pipe 21 is preferabl supported by a bracket 22 detachably li xed to the carriage 2.

An air mixer 23 is provided in the pipe 22 and is regulated by a slidable sleeve 24. Gas is supplied through a flexible tubing 25 to a pipe 26 which is connected to a regulatmg valve 27 having a manual control 27; and a stop-cock 28 is provided between valve 27 and the air mixer 23. A tube 29 leads from the casing of valve 27 and along 16 pipe 21 to the burners 18, where it forms a pilot burner 30 shielded by a guard 31 on the burner pipe. The supply of fuel through tube 29 is regulated by a valve in casing 27 having a manual control 29.

Stop-cock 28'which controls the supply of fuel to the burners 18 is turned on and off by a usual rotatable plug 32 having a cross head 34 for operating the same. The cross head is turned for opening or closing the,

stop-cock by cam mechanism cooperating with rollers 33 .head.

The cam mechanism is adapted to be shifted into the path of the rollers for turning the cross head as the heater structure is moved back and forth with carriage 2, stopcock 28 being open so that the burners are lighted when the cross head is horizontal, and being turned to closed position for extinguishing the burners by turning of the cross head to vertical position. During normal operation of the press with the trip released the cam mechanism is out of the -path of travel of rollers 33, but is shifted,

into said path of travel so as to turn the cross head 34 by the tripping of the press". For this purpose the cam mechanism is preferably mounted on the fountain tri connecting rod 15, the movement of whic as the pressis tripped or released shifts said cam mechanism into operative or inoperative position. As an instance of this arrangement anarm 35 is detachably clam ed on rod 15 as shown at 36, and is prefera hly braced by an arm 35 clamped to the rod 15 and the arm 35. An open frame 37 is supported by arm 35 with the valve mech anism of the heater structure adapted for movement back and forth through said frame; and fingers 38 on the frame are preferably slidably mounted in'a guide 39 on delivery way 1, to hold the frame in osition during shifting thereof with the f duntain trig connecting rod.

ams 40 and 41 are mounted in the respective ends of frame 37, the cam 40 comprising surfaces 40" in alinement with the respective rollers 33 and curving upwardly and downwardly respectively to a vertical end abutment surface 40"; and the cam 41 cross head 34 as the latter is moved back journaled on the ends of the comprising a horizontal surface 41 of a width to aline with both rollers 33, and having downwardly inclined ends 41 ada ted for engagement by the respective ro ers.

- In normal operation of the press with the trip released, rod 15 is shifted to its limit of movement toward the delivery end of the press as shown in Fig. 2, thereby moving cam 40 beyond the limit of movement of and forth with the delivery carriage of the press, and positioning cam 41 so that the rollers 33 will pass" over the same without contact with inclined surfaces 41, when the cross head is in horizontal position. The heater will thus continue to burn throughout normal operation of the press.

\Vhen the press it tripped, connecting rod 15 is shifted in the opposite direotion'as shown in Fig. 3, thereby shifting cam 40 so that its vertical abutment surface 40 and its curved surfaces, 40 are within the limit of movement of the horizontally disposed cross head as the latter is moved back and forth with the delivery carriage. As a conse- ,quence one or the other of rollers 33 will ride upon its cooperating curved surface 40 and thence along vertical abutment surface 4O so as to turn the cross head to vertical sition, the surface 40 being at the end 0 the limit of movement of the cross head when the latter is thus vertically positioned. The turning of the cross head closes stop-cock 28 as previously described, and thus extinguishes burners 18.

Tri ping of the press as thus described, also owers rod 15 as shown in Fig}. 3, thereby shifting cam 41 below the pat of travel of the vertically disposed cross head as. the latter continues to move back and 105 forth with the delivery carriage, so that roller-s33 are out of contact with cam 41 and thus permit the cross head to remain in vertical position for closing of stop-cock 28 and extinguishing of the burners of'the heater, as long as the press remains trip ed.

When the press is again re eased from tripped position, rod 15 is returned to its normal position, thereby again moving cam 40 beyond the limit of movement of the cross head, and shifting cam 41 upwardly as shown in'Fig. 3, so that one or the other of the rollers on the vertically positioned cross head will ride upon its cooperatinginclined surface 41" as the cross head moves back and forth with the deliver carria e, and thereby turn the cross head ack tOfilOIiZOIltfil position.

Stop-cock 28 is thus reopened so that the burners 18 are lighted by pilot 30; and the cross head will then remain in horizontal 0-. sition as it is moved back and forth, so 1; at the heater will continue to burn until the press is again tripped, since with the cross head in horizontal position, cams 40 and 4 {1.
