Be it known that I, WILLIAM J. iJANING- To alt whom it may concern: I l

- device from the right hand end.

, ing embodiments 0 none, a citizen of the United States,"residing in New York city,

certain new and useful Improvements in Attachments for Printing-Presses, of which the following is a specification.

heat

This invention has for its object to vicle means for producing an intense in close proximity to the cylinder of a print: ing press adjacent the guides by electrical means, at the same time to prevent any dangelof fire from undue heat beingcommunirated to the paper that-is being printed and delivered. i a

A further object is to provide means for readily controlling the amountor intensity of the heat generated.

'In the accompan ing drawing representmy invention Figure 1- shows the device in section, as applied to a press. Fig. 2-shows enlarged avertical section through one end portion of the device. Fig. 3 is a fragmentary view showing the other end. Fig. 4 is an end elevatigipn of the i 5 is a fragmentary bottom plan view, and Fig. 6 is a section through one of the plugs or terminals.

The device is shown as comprising a shell 7- shown as somewhat semi-circular and is suitably supported by arms 8 from the cross in the county of New York and State of New York, have inventedthis means t bar 9 that sup orts the guides 10 for a c linder press in t e usual manner. The gui es cooperate with the feed table 11 and are raised and lowered in the usual manner well known in the art. The shell 7 is supported to be in close proximity to the cylinder 12 of the ress between the guide and the crossbar. en the paper is fed in, the bar rocks and the guide rises as is well understood, and hence the shell will rise also a s ort distance. Upon completion of therevolution of the press the printed sheet will again pass under the guide rod 9 to be delivered to the tapes or the fly. At this time 'i the guide 10 is not raised and the shield 7 will be in close proximity to the paper that at this portion of the revolution is held in contact with the cylinder.

The shell is provided with one or a series of electrical conductors extending from end to end in the shell and removed from its bottom plane so that they will not be too near the paper or cylinder. Three conductors l3,

ities of the bands, wires 19, 20 and 21 connect with three terminals 22, 23 and 24 whereby each of the bands has a se arate term1 nal.- Spring lugs 25, 26 and 2 are provided, one of w ich is shown separately in Fig. 6, and connect by'wires 28, 29 and 30 with a lead wire'31; Each of these plugs 17 with a terminal 18. At the other extremcomprises an insulating shell 32 and a conducting sleeve '33 that islongitudinally s lit to frictionallv engage the plugs 22 24'. l3y e current flowing in through wire 31 and having exit ,through wire 18, can be'caused to pass throu' h any one, or two, or'all of the three ban s as desired. And

by having these bands oLditferent ohmic resistance, seven different combinations can be produced. Preferably the current is taken from the resistance box of the electric motor that operates the press, when driven by a motor. Hence as the current is increased or diminished the amount of heat generated will vary according to the duty required. These bands preferably are supported by asbestos blocks 36, 37 on opposlte sides that are suspended by lugs 38 from -the shell 7. And. the shell 7 that is preferably of metal is shown provided with a lining of-asbestos 39. At each end the bands are elastically supported to prevent their sagging when they become heated s would otherwlse" be the case. The cross ar '16 is connected by wire coils 41 and 42 with an insulated piece 43 secured in the end casing 44 of the shell. At the other end the bands .have springs 45, 46 and 47 connecting them with an insulating block 48 secured in the end casing 49. It will be seen that these bands are placed some distance inside of thev bottom plane of the shell.

At the bottom of the shell is preferably provided an insulating band or plate, to prevent any possibility of the wires sagging to engage the paper or the paper rising up to,

engage the wire; thus preventing any possibility of fire or unduly heating the paper. The shell is provided at its bottom wit a plate 50 of perforated metal that is held in place by lugs 51 bent inwardly at the bottom of the shell. On top of this plate inside of the casing is placed a thin layer or sheet of suitable insulating material such as asbestos 52, that will permit heat to be radiated from the device yet absolutely prevent any 1 the outside and by the asbestos lining of i the shell 39 on the inside. heating device is to take the dampness and moisture of the sheet before it passes around the cylinder and is printed. And when the trical heater, it will have the effect of drying and setting the ink, and thereby preventlng the effect known as offset when the sheets jogged up. This heater will also perform the function of removing or preventing the static electric charge that is frequently prestheir being lined up on the delivery hoard.

Having thus described my invention, 1 claim:

1. In a cylinder press, the combination with the cylinder, the feed table and the guides. of a shell extending across the cylinder in close proximity thereto a short distance beyontLthe guides, electric conductors extending longitudinally in the shell located inside of the bottom plane of the shell. and an insulating plate carried by the shell below the conductors.

2. In a cylinder press. the combination with the cylinder. the feed table and the guides. of a shell extending across the cylinder in close proximity thereto near the guides. electric conductors extending longitudinally in the shell located inside of the bottom plane of the shell, said shell being The eifectof this carried by the lllde supports of the press to be raised and lowered therewith.

In a cylinder mess, the combination with the cylinder, the feed table and the guides, of a shell-extending across the cylinder in proximity thereto a short distance beyond the guides, electric conductors extending longitudinally in the shell and located inside of the bottom plane of the shell. and spring inenibeis at the end portions of the conductors, the said springs having their connection with the shell insulated therefrom.

4. In a cylinder )ress, the combination with the cylinder, the feed table and the 3 guides. of a shell extending across the cylprinted sheetagain passes beneath the elecinder in proximity thereto a short distance !beyond the guides, electric conductors extending longitudinally in the shell and located inside of the bottom plane of the shell, are delivered, and especially when tlie are 1 spring members at the end portions of the conductors, the said SPX'IIIU'S having their connection with the shell insulated therei from. the device having a terminal at one entin printed sheets which tends to prevent end connected with the conductors independent of the springs, the other end of the device hating a separate terminal for each conductor, and a wire connecting the terminals with each of the said conductors.

I). In a cylinder press, the combination with the cylinder. the feed table and the guides, of a shell extending across the cylinder in close proximity thereto a short distance beyond the guides, electric conductors extending longitudinally in the shell located inside of the bottom plane of the shell, an insulating plate carried by the shell below the conductors, and a strip of metal outside of said insulating strip.
