Application filed June 1.0, 1901.

To a/ZZ whom t may concern:

Be it known that I, CHARLES G. HIGH- TOWER, a citizen of the United States, residing iu the city and county of San Francisco, State of California, have invented certain new and useful Apparatus for CalkingSeams v f Vessels; and IV do hereby declare the following to be a full, clear, tion of the same.

The present invention relates to a new and useful apparatus for use in calking seams of ship-decks or work of like character orv where it is desired to make water-tight the opening between planks; and the object of the inven tion is to enable the oakum or calking material to be driven with greater rapidity, more uniform, and with compactness unattainable by hand-calking The calking of vesselsl is at present done by hand, expert calkers being required for such purpose. As a result the oakum is not driven with uniformity, inasumch as itis impossiblefor the calker to drive the oakum with an even blow throughout the entire work. However, the main objection to this manner of calking is the slowness with which the lwork is accomplished and the expense attached thereto, as an expert calker is un; able to cover more than about one hundred and fifty feet for a days work. In addition to the calker an expert puttier is required to putty the calked oakum after the calker has completed his portion of the work, and where` the work is to be performed upon an old vessel a workman must be employed to remove the old oakum from the seams before the calker is enabled to apply. the vnew oakum therein. These various steps require that much time be devoted to the work of properly calking a vessel and the expenditure of considerable money therefor. l

While the present invention performs the work of calking the seam, it is likewise adapted to apply putty to the calked seam, and in case of an old vessel being recalked means are provided for removing the old oakum from within the seam, so as to clear the same in advance of the calking mechanism.

Practical experience has demonstrated that by the employment of the hereinafter-described apparatus about Iifteen hundred feet and exact Ydescripseriiu No. 63,907. Nt model.)

may be successfullycalked-and puttied in one day, and that without the aid of expert calkers. Y..

The hereinafter-described apparatus is believed to bel theiirst automatically-operated means whereby the work of calking the seams of vessels 'is mechanically performed by forcing theV oakum intothe seam under a uniform pressure. Y Hence the intent is to cover this feature broadly, whether the apparatus be employed simply for the operation. of calking orin connectionwith the reaver and puttier attachments or in combination with either of said attachments.

In orderto comprehend the invention, reference should be had to the accompanying sheets of drawings, wherein- Figure 1 is a side View of the calking appavratus with the reaver attachment for removing the old oakum and the attachment whereby the calked seam is puttied applied thereto. Fig. 2 is an enlarged longitudinal sectional top plan view taken on -line rx, Fig. 1, the reaver and puttier attachment being xremoved. Fig. 3 is a broken part sectional-view,

The numeral 1 is used to indicate the frame or base plate of the machine, supported by the rollers 2 and 3. The frame or base plate has secured thereto the uprights or standards 4 4', which carry the cylinder 5. In the present case the frame-plate, standards, and cylinder are made integral. This, however, is immaterial, as the said parts may be cast separately and united in any suitable manner. Within the cylinder 5 works the piston 6, to the stem 6 ot which is connected the hammer 7. This hammer is provided with a removable head 8, which is dovetailed thereto. The hammer is provided with the side extensions 9, which work within the guides or Ways 10, cut in the inner face of the standards or uprights 4 4, Fig. 1 of the drawings. The hammer acts upon the stem 11 of the calking-tool 12 during the reciprocating motion ot' the piston 6. Said stem 11 works within a sleeve 13, fitted in a Vertical opening 14 in the frame or base plate 1, being held therein by the tightening-screw 15. The tool is prevented from dropping out of its sleeve or shell by means of the screw 16, extending therethrough and into a vertical slot 17, cutin the face of stem 11. The said stem is held upward by the pressure of the recoilspring 17', which bears against its enlarged head 12. Thus the calking-tool is normally held out of and above the seam to be calked and, being spring-actuated, automatically returns with the upward movement ol' the hammer, Fig. 6 of the drawings. In the present case the calking-tool is detachably connected to its stem 1l. Consequently the tool may be removed therefrom for any desired purpose. y

The cylinder 5 is provided with the inlet and outlet openings 18 19, Fig. 12 of the drawings, which openings are controlled by the rotatable cage-valve 20. This valve is open at its bottom, and through the side wall thereof the inlet and outlet ports 20 2l are cut, which register, respectively, with the openings 18 19 of the cylinder. Vhen port 21 registers with opening 19, so as to open same, port 20' is out of register with opening 18 and said opening is held closed. This valve is rotated in order to open and close said ports during the stroke of the piston G, its fiat stem 22 working within the hollow portion 23 of the piston. This stem 22 is formed with a twist, and it extends through the elongated opening 23 in the end plate 25 of the piston.

The cage-valve rests upon the seat 26 and is held in place against longitudinal movement by the cylinder-head 2G'. During the reciprocating movement of the piston the valvestem 22 is turned to the right or left, depending upon the direction of the pistons stroke. Inasmuch as the stem is rigid with the cagevalve, the movement of said stem rotates the cage-valve 20, so as to open or close inlet and outlet openings 18 19.

In the wall of the cylinder is the passageway 27, which leads from the inlet-opening 18 and communicates with the intcriorof the cylinder at a point below the downstroke of the piston. With the inlet 18 is connected the main supply-pipe 28, Figs. 1, 2, 10, and 12 of the drawings. This supply-pipe is provided with a valve 29, by means ot' which the admission of the motive fluid to the main cylinder is controlled.

Any suitable motive power may be utilized to operate the apparatus, although pneumatic or compressed air is preferred. An air-compressor (not shown) is located at any convenient point, and the compressed air is supplied by means of the flexible tube 30, which connects the air-compressor with the main supply-pipe 28.

The supporting-rolls 2 3 are secured to axles 30'31, which work in bearings of the frame or base 1. In the present case the rolls 2 constitute the drive-rolls of the apparatus, being driven by the worm 32,'which meshes with worm-gear 33, mounted upon axle 30'. The worm 32 is carried by the wormshaft 34, which shaft works within the tilbular casing 35. This casing is fulcrumed by pin 3G to the upright or standard 4', Figs. 1 and 3 of the drawings.

The upper end of the worm-shaft 34 is attached to the bracket 36', located within the motor-casing 37. Said bracket carries the gears 38 39, which are driven by the intermeshing pinion 40, Fig. 13 of the drawings. This pinion is attached to spindle depending from disk 42 within the casing, said spindle extending through a central opening in the diaphragm 43, which divides the casing. Within the casing and attached to the disk 42 are located the air-cylinders 44, in each of which works a piston. This constitutes an airmotor of well-recognized type, and specic description thereof and as to its workings is not required. The casing t is formed with an air-inlet port 48,'through IOO IIO

which air is admitted for the working of the i pistons of the air-cylinders, the air under pressure entering the cylinders through the ports 49. The exhaust from the cylinders makes its escape from the casing through the opening 42'.

To the air-inlet port 48 connects the hose 50, leading from point 51 of the branch airsupply pipe 52. By means of the valve 52 the supply of air to the drive-motor is controlled. This branch supply 52 is connected with the main supply-pipe 28, the flow of air from said main supply-pipe through the branch supply-pipe into hose 50 being regulated by the said valve52'.

From points 54 55 56, respectively, of the branch pipe extend the` hose connections 57 58, and 59, the two former of which connect with the putty-cylinder 60, while the latter connect with the air-motor` 61 for driving of4 the reaver attachment. 'lhe putty-cylinder 60 is supported in brackets 62, extending from standard or upright 4', while the motor 6l is held within bracket 63, extending from standard or upright 4, which bracket also supports the oakum-reel 64, Fig'. 1 of the drawings.

, By preference the putty-cylinder is made in sections 66, united by bolts 67', the sections being separated by diaphragm 68. In the lower section 66 of the cylinder is placed the putty which is to be delivered to the seam after the oakum has been driven therein. Within the lower cylinder-section works the piston 69, while in the upper .section of theA cylinder works the piston 70. These pistons are connected by stem 71, and they are gradually forced downward'hy the pressure ofthe air entering the cylinder from 'the connections 57 and 58, that from connection 57 being admitted into the upper section above piston 70 and that from connection 58 being admitted into the lower section above the piston 69. The air thus admitted causes vthe pistons to move downward and gradually force the putty from the lower section through its tapering outlet v72 into and through tubular extension 73. This extension is held within guide-openings 74, and to the lower end thereof is attached the putty-guide 75, Figs. l and 3 of the drawings. To raise the pistons within the cylinder-sections, the hose connection 58 is disconnected from inlet-pipe 75 and connect-` ed with pipe 76, which enters the cylinder above diaphragm 68, and air thus admitted to the cylinder below piston 70, the pressure of which forcesf said piston. and piston 69 through the medium of connecting-stem 7l -upward.A This is only necessary when it is de- 80, respectively. During the downward movement of the pistons the exhaust or` outlet of the cylinder is through pipe 76, which is nor` mally an open one. To refill the lower section ofthe cylinder with putty, the upper section is disconnected and the piston removed therefrom, when free access may be had to the interior of the lower section of the cylinder.

By means of the Valve the admission-of air from the branch supply 52 through the connection 59 to the reaver-motor 61 is controlled. The motor employed'for operating the reaver is the same as that described in connection with the motor for driving the apparatus, Figs. lvand 14'of-the drawings.

When used to drive the reaver,` the form of is dispensed with and the depending spindle 78 of the rotating disk works in bearings of the bracket 81v and4 has secured thereto `the gear-wheel 82. This gear-wheel meshes with pinion 83, secured to the upper end ofdriveshaft 84, which shaft extends through guideopening in bracket 81 and guide-opening,

85 in bracket 86, extending laterally from frame 87. To the lower endf portion of the drive-shaft is keyed or otherwise secured the crown gear-wheel 88, which meshes lwith crown-pinion 89 of lcross-shaft 90. This crossshaft works in the adjustable bearing-boxes 91, fitted to slide between the arms 92 of the frame'87. Said boxes are raised and lowered by means of the screw-bolts 94. Upon the v cross-shaft 90.between the adjustable bearing-boxes is secured the reaver 95, which is held a slight distance in advance of the gage-- lplate 96.

The reaver is in line with the seam to be calked during the operation of theivapparatus, and its function is to remove from the seam the old oakum and putty, thus pre-4 senting a free seam tobe calked. When the seam is that of a new vessel or beingcalked for the first time, the reaver is not necessary.

In such case it may be raised clear of thev seam or the entire reaver attachment may be removed.

vIn the main frame or base plate near-each end the cylinders 97 and 98 are located.l

Within cylinders 97 works piston 99, which is held outwardly or downwardly pressed by.

spring 100. The stem 101 of each piston projects beyond the cylinder and its lower'end is bifurcated, and between the arms of stem working in cylinder-97 theguide-roll 1O21is held. This guide-roll iits within the seam to IOO be calked and guides theapparatus, so as to Y hold the calking-tool in line therewith. To said stem in advance of the guide-roll is attached the gage-plate 96, which works in the seam to be calked in advance of the forward guide-roll. The object of said gage-plate is to clear the seam` of loose putty or oakum left g by the. reaver.

Between the cylinders 97 98 are located cyl- I inders 98', and in each of said cylinders works the piston 103, held down t by4 spring 104.

The stem 103 of said pistons, like those of` pistons 99, extends' below the main frame or base plate, and the-lower end of each stem is bifurcated and carries between its arms the roll 105, said roll having a grooved periphery.

`The forward roll acts as'feed-roll for-the These rolls kare carried by the stems 109 110 of pistons 111, which work within cylinders 113. These pistons are held upward within the cylinders by springs 115, so that the rolls 107 108 are normally held clear of the deck. When the pistons are forced downward, the rolls 107 108 bear against the deck and raise or jack the entire apparatus clear thereof. As thus raised a workman by exerting slight pressure thereon may easily roll the apparatus to the seam to be calked. The rolls 107 108 are lowered by the air-pressure admitted to cylinders 113 above the pistons 111. Air is supplied to the. cylinders through ports 116 117 by means of the connections 118 119, which connections are attached to the branch supply-pipe at points 120 121, respectively. The supply of air to the cylinders is controlled by the three-way valve 122, which admits air from the branch supply-'pipe to the connections simultaneously. At the same time air is admitted within the cylinders 97,

98, and 98 in order to raise the stems 101 y and 103 and the rolls carried thereby. The air is admitted below the piston of each cylinder through the couplings 123 124, which connect, respectively, with the said cylinders and the connections 118 119. the three-way valve 122 is turned to cut ofi. the supply of air from the branch supplypipe communication is established between the connections 118 119 and the exhaust 125 of said branch supply. The pressure of springs 100, 104, and 115 returns the pistons to their normal position, the air from the cyli sired that the oakum be oiled, so as to preinders escaping through exhaust 125.

The thread of oakum as unwound from the reel 64 passes through guide-tube 126 to thel feed-roll 105 and is held in proper position below the calking-tool 12 and presented in a straight line thereto by means of the shoe 126. This shoe is provided with a tool-opening 127 in its bottom and is supported below frame 1 by means of the rods 128, which work within seats 129 and are held pressed outward by springs 130. By mea-ns of these springs the shoe is held firmly pressed against the deck being calked. Within this shoe is located the tucker-wbeel 131, which is mounted upon the shaft 132. This wheel engages the oaku m fed through the shoe and tucks or bunches same within the shoe over the outletopening. The object of thus tucking orbunching the oakum is that a ball, so to speak, of oakum may be presented to the action of the calking-tool in case of a wide seam and necessity of repeating the act of calking avoided, which would bue required in case onlya strand of oakum should be driven into the seam at each stroke of the calking-tool. By thus tucking or bunching the oakum a suiicient quantity of oakum is driven into the seam with each stroke of the tool to fill the same. The tuckerwheel is actuated by the stroke of the hammer 7. This hammer carries a lug 133, which during its upstroke engages with the collar 134, secured to rod 135, and lifts the said The moment y i pawl mechanism and the travel of the tuckerwheel with each throw of the said mechanism vaas-io rod a given distance. Said rod is connected at its lower end to link 136, Figs. 3 and 9 of the drawings, which link is loosely mounted .upon shaft `137. To the rod 135 is attached the pawl 138, which engages with the pawlgear 139, secured to shaft 137. With each upward stroke of the hammer the rod 135 is lifted, which in turn through its pawl mechanism rotates the gear 139.

The rotation of this gear im parts a corresponding rotation to shaft 137, which carries the larger gear 140. This gear meshes with pinion 141, so as to impart'rotation to shaft 132, to which the tucker-wheel 131 is secured. Thus with each upward stroke of the hammer 7 it will be seen that the tncker-wheel is driven by a step rotation. The length of the stroke of rod 135 may be increased or decreased by means of the lever 142, fulcrumed to one of the standards of the apparatus, Fig. 15. This lever is connected at its outer end to upper end of the rod 135, and at its inner end portion is provided with the spring-catch 143, which catch engages with quadrant 144. By raising or lowering the actuating-rod 135 through i its adjusting mechanism the distance of coll lar 137 from lug 133 is increased or decreased and a longer or shorter throw imparted to the correspondingly increased or decreased. The

l tucking or bunching of the oakum is heavy given the tucker-wheel.

During the operation of calking it is deserve the life thereof while in the seam. For this purpose there is an oil passage-way 145 formed in the seats 129, Figs. 1 and 7 of the drawings, with which connect oil-tubes 146. These tubes lead from the oil-cup 147. The oil fed to the seats 129 gradually escapes therefrom and satu rates the oakutn held Within the shoe 126. i

It is possible that during the work of calking the calking-tool 12 may stick in seam 148 of deck 149 when driven therein by the hammer 7 and the pressure of recoil-spring 17 be insufficient to raise the tool therefrom. To provide against this, there is attached to the head 12 of tool-stem 11 the lift-rod 150,

Fig. 1 of the drawings. In this rod is cut a slot 151, within which works a lug 152, projecting from the hammer 7. This lug 152 in case the pressure of recoil-spring 17 should prove insufficient to remove the calking-tool during the upstroke of the piston 6 engages with the upper end of slottedlift-rod prior to the piston completing its upstroke and carries the same therewith. This upward movement of the lift-rod suflices to release the calking-tool from the seam, when the pressure of the recoil-spring will return the tool to its normal position.

As the hammer is driven at a high rate through the medium of the actuated piston 6, the calking-tool will have correspondingly a IOO lIO

' and as the blow of the hammer is a `uniform onethe oakum will be driven into the seam 148 under an even. and muclrgreater pressure than can be obtained by hand-calking. During the operation of calkin g the apparatus is driven longitudinally by means of the hereinbefore-described worm mechanism along the deck. As the apparatus performs the work of calking Yputty isforced from the putty-cylinder 60 by the air-pressure acting upon the pistons 69 70 through extension 73 and guide 75 onto the oakumfwithin the seam. The putty thus forced within the calked seam is properly smoothed and pressed by the spreaderv 153, secured to the lower end of stem 101, working withincylinder 98, Figs. 1 and 3 of the drawings. t,

In case the'deck to be puttied is a new one then the reaver attachment is not required, and the same may be removed from the apparatus or the reaver raised by its adjusting devices, so as to clear the deck to be calked. The reaver attachment is' only designed .for use duringthe calking of old seams or such seams as require the old oakum to be removed. Y

It is not required that the puttier be used at the same time as the calking mechanism, although it is preferred so to use same. If desired, Vthe Work of calking may .be completed and the puttying done thereafter as a distinct operation.

operations vmay beperformed--to wit, the

reaving of the old oakum, calking of the oakum, and puttying of the calked seams. These .operations can be conducted at the Sametime or separately, as the Work mayrequire.

When desired to stop thelongitudinal travel of the apparatus, the worm 32 is thrown out of mesh with Worm-gear 33 by means of hand-lever 154. Thishand-lever is attached to eccentric 155, over which fitsv link 15.6. Said link is connected to lower end portion of fulcrumed casing 35, which contains the worm-shaft 34. As the hand-lever 154is thrown upward the eccentric .155, is turned so as to draw the link 156 inward. The inward movement of said link carries the lower end of :casing 35 therewith and places worm 33 out of mesh with its worm-gear. thrown out of gear, travel o f the apparatus ceases.

The operation of the-various parts is controlled by the admission of the air from vthe main supply-pipe tothe respective pistons and motors. s

As before stated, any suitable style of mechanism may be employed for imparting motion to the apparatus and operating its various parts, although compressed air is preferr-ed, owing to itsease of handling.

The air for operatingthe calking-tool Ais admitted to the cylinder '5 above and Vbelow the piston-head Gthrough portZO'` and pas- When thus sage-way 27. While port 20' is opened the air admitted to the cylinder through passageway 27 is sufficient to. forman ai r-cnshionfor thedownstroke of the piston. The moment the said port is closed the full pressure of air is admitted through said passage-way in order to force-the piston upward. i
