HICKOK IJANUFACTURING COMPANY, OF HARRISBURG, FIE-NNSYLVANIA, A GORIPOEATION OF PENNSYLVANIA PEN OPERATING MECHANISM FOR E-ULING MACHINES Application filed November 19, 1929. SerialNo. 168,333.

The object of the present invention is to provide a novel and efliective pen-carrying means and the operating mechanism therefor that will permit successful striking at high speed.

Another and important object is to provide novel means by which the pen-carrying member may be easily and accurately adjusted so that a set up of pens can be readily shifted as an entity for ruling on opposite sides of sheets, where for example, margins are desired.

A still further and important object is to provide novel ink-feeding means that is adjustable with the pen-carrying member so that the parts always maintain their properly related positions.

In the embodiment disclosed, a suitable frame is employed that is preferably of metal, including a front (as viewed in Figure 1) horizontal bar 121 and a rear horizontal bar 122. On these bars are mounted a plurality of ruling instrumentalities designated generally by thereference numeral 123. As they are duplicates, a description and disclosure of one will sulfice for all.

On the front bar 121 is located a post 12a having a base 125 with side flanges 126 that embrace the upper flange of the bar 121. The base is provided with a longitudinal slot 127 through which is passed a holding screw 128 threaded into the bar'121. As a consequence the post 12& is capable of adjustment longitudinally along the bar 121 and can be secured in its adjusted position. On the rear bar 122 is mounted a corresponding post 129 having a base 130 adjustably riding on the bar 122 and held by a set screw 131. The front post 124 has a split collar 132 vertically adjustable thereon and adapted to be contracted by a bolt 133 so that the collar can be fixed at any point on the post. This collar is provided with an outstanding journal box 134- having a ball bearing or ball race 135. Journaled in this ball bearing is the reduced portion 136 of a sleeve 137 that projects beyond the rear side of the box 13 1 and has a split portion 138. The sleeve is retained in the box by a collar or nut 139 threaded on to its outer end and located within the outer side of the box 134 (see Figure 3). The rear post 129, as shown particularly in Figures 2, l, 5 and 6, has also mounted thereon a vertically adjustable split collar 1410 that can be clamped by a holding bolt 14:1, and this collar has an outstanding box 1 12 provided with a ball bearing 143.

Mounted between the posts is a pen-carrying member. This member comprises a lower bar section 144 (see Figure 12), preferably of metal and an upper clamping bar section 145 preferably of wood. These are held together by transverse screw bolts 146 whose heads 147 are countersunk in the clamping bar 145 and whose shanks are threaded into the lower bar 144. The bars clamp between them the shanks 148 of pens 149 that can obviously be placed as desired. Projecting from the ends of the lower or supporting bar section 144 and fixed so as to turn therewith, are shaft gudgeons 150 and 151. The shaft gudgeon 150, as shown in Figure 8, extends through the sleeve 137 and projects well beyond the box 134 where it is provided with a handle knob 152. This gudgeon 150 is surrounded by the split portion 138 of the sleeve 137 and consequently said sleeve can be contracted upon the gudgeon 150 so as to be fixed thereto. This contracting operation is accomplished by means of a bolt 153 passing through the split portion 138 of the sleeve 137. The gudgeon 151 is journaled in the rear box 142 and the beam is short enough so that it can be adjusted longitudinally of itself or transversely of the machine by sliding the gudgeon 150 in the sleeve 137 and the gudgeon 151 in the box 142. Preferably there is placed on the outer end of the gudgeon 150 or between the box 134 and the knob 152 a split collar 154 that can be contracted on the gudgeon by means of a tie screw'155. This collar can be therefore fixed at any point desired on the outer end of the gudgeon 150 and when the split portion 138 of the sleeve 137 is loosened, by pushing inwardly on the knob 152, the pen beam can be shifted rearwardly until the collar 154 strikes the outer end of the sleeve 137. In this way any amount of shift of the beam can be accurately secured.

The portion of the sleeve 137 behind the box 134 is provided with an outstanding operating crank arm 156 that is angled rearwardly and outwardly, so that its outer free end overlies the front beam bar 121, as shown in Figure 2. This frame bar directly behind the post is provided with a horizontal slot 157 and slidably mounted on the inner side of said frame bar is a box 158 having an outwardly extending shank 159 slidable in the slot (see Figures 3 and 10). On the outerside of the frame bar is a clamping plate 160, through which is passed a clamping screw 161 threaded into the shank 159. As a consequence while the box can be shifted along the frame bar 121, it can also be fixed against movement and in different adjusted positions. The box has a vertical guideway 162 in which is a vertical reciprocatory plunger 163 held in place by a cap plate 164 secured to the box on opposite sides of the guideway 162 by screws 165. This plunger is adapted to be engaged by the lower head 166 of a screw 167 threaded through an intermediate portion of the arm 156. The plunger in turn is adapted to be elevated through the medium of the usual cam head 168 in which can be mounted cam plates 169 that operate on a roller 170 journalled in the lower end of the plunger 163. The plunger is preferably hollow, as shown at 171 and waste or other absorbent material 172 is placed therein. An oil port 173, formed in the upper portion of the plunger alines with an oil groove 174, and serves as a means for directing oil into the chamber. The cam plates 169, as shown particularly in Figure 11, are of a predetermined and novel formation. That is to say, their front edges are formed on a reverse curve 175, while their rear ends 176 are substantially radial tothe cam head 168. The plunger 163 is individually elevated by a spring 177 located in a socket 178 in the box 158. This spring operates on a plunger rod 179 that bears against a pin 180 carried by the plunger 163. Its upward movement is limited by a stop hook 181. The free end of the arm 156 isprovided with another supporting screw 182 threaded vertically therethrough and having at its lower end a head 183. This head is adapted to rest upon a latch plate 184, pivotally mounted on the box 158 as shown at 185 and connected to a spring 186 that tends to pull the latch 184 from under the head 183. Said latch is provided along its rear side with an upstanding flange 187 that abuts said head when the latch is beneath it. The box is adjusted horizontally by a screw 188 threaded thereinto and j ournaled in a bracket 189 fixed to the frame bar 121.

In order to insure the downward movement of the arm 156 and consequently the striking of the pens 149, the sleeve 137 is provided with a rearwardly extending arm 190 to which is attached the lower end of a coiled spring 191 whose upper end is connected to a vertically movable tension screw 192. This screw slidably passes through an ear 193 in a collar 194, fixed to the upper end of the post 124. An adjusting nut 195 threaded on the upper end of the screw 192 is supported on the ear 193.

The ear 193 of the collar 194 is actually an outstanding portion of a rearwardly extending arm 196 (see Figure 2) and this arm terminates in a dowturned bifurcation 197. In this bifurcation is located one end of a supporting bar 198 held in place by a screw 199 (see Figure 8). The bar extends rearwardly of and parallel to the pen beam and its rear end is mounted in a corresponding bifurcation 200 of the arm 201 of a collar 202 adjustably mounted on the upper end of the rear post 129, as shown in Figures 2 and 5. The bar 198 supports a reservoir 203 for ink, and said reservoir 203 is an elongated tank or container, preferably of sheet metal, and has its rear wall flanged over to provide a hook 204 that engages over the upper margin of the supporting bar 198, as shown in Figure 13. Yarns or wicks 205 lead from this reservoir to the pens 1 19. The reservoir is slidable along the bar 198 and this sliding movement is preferably effected automatically with the longitudinal adjustment of the pen beam.

To this end the gudgeon 150 between the front end of the pen beam to the sleeve 137 has clamped thereon a split collar 206 provided with a rearwardly extending arm 207 that carries an offset finger 208 having a slot 209. A bifurcated saddle plate 210 placed astride the adjacent end wall of the reservoir has a rearwardly extending arm 211 provided with a depending pin 212 that engages in the slot 209. This is shown in Figure 13. The slot 209 and pin 212 obviously permit the pen beam to rock or turn without affecting the reservoir, but if the pen beam is adjusted longitudinally, the arm 208 bein correspondingly moved, will press against the pin 212 and the saddle 210 will push the reservoir 203 along the bar 198, so that the reservoir will be adjusted with the pen beam.

lVith this structure, it will be noted that the pen-carrying member or pen beam is ex tremely light in weight and it is practically balanced because its bulk or body extends on opposite sides of the axis of rocking movement. This is very desirable for high speed work. lVhen the actuating arm 156 is held elevated by the latch 184, the head 166 of the screw 167 is raised out of contact with the top of the plunger 163. The plunger being therefore relieved of weight, the spring 177 operates to raise said plunger so that the roller 170 is out of the path of the cam plates 169. Therefore even if the cam head 168 is rotating, it is acting on no moving part of the pen beam operating mechanism. If, however, the arm 156 is raised, so that the head 183 of the supporting screw 182 is disengaged from the latch 18%, the spring 186 will operate to swing said latch from beneath the head 183. Consequently the head 166 of the screw 167 will rest upon the plunger 163. The weight thereof is sutficient to overcome the spring 177 and depress the plunger 163 so that the roller 17 0 is in the path of the cam plates 169. ()bviously therefore as the cam head rotates, the cam plates will successively raise the plunger, elevating the arm 156 and rocking the pen beam so as to elevate the pens. The reversely curved front ends of the cam plates have been found to be practically eiiicacious in causing the raising movement with sufiicient speed and yet w'th so little vibration that the pens leave the paper with accuracy and at the precise point desired. he utilization of the plunger between the cam plates and the rocker arm 156 has been found also to be very helpful in eliminating vibration at high speeds in order to secure accurate Work. Obviously and as already explained the pen beam can be readily adjusted with great accuracy in order to shift the set up to work at different points and the pen holding structure is itself very simple and readily accessible.

From the foregoing, it is thought that the construction, operation and many advantages of the herein described invention will be apparent to those skilled in the art, without further description and it will be understood that various changes in the size, shape, proportion and minor details of construction may be restored to without departing from the spirit or sacrificing any of the advantages of the invention.
