SPECIFICATION forming part of Letters Patent No. 645,016, dated March 6, 1906.

Application filed Se tember'lS, 1899. Serial No. 780,362. (No model.) i

To all whom it may concerto.-

Be it known that LHENRYRosnof the firm of Rose Brothers, a subject of the Queen of Great Britain and Ireland, and a resident of Albion Works, Gainsborough, in the county of Lincoln, England, have invented certain new and useful Improvements in Machines for Inclosing in Wrappers Washing-Blue, Black-Lead, Soap, or other Substances, (for which I have applied for a patent in Great Britain, No. 3,514., dated February 17, 1899,) of which the following is a specification.

My invention has for its object to provide a machine for inclosing in wrappers washingblue, black-lead, soap, or other substance in a more rapid and efficient manner than heretofore.

A machine constructed according to my present invention operates continuously and not intermittently, as is the case with machines heretofore in use for inclosing blocks of substance in wrappers, and in order that my invention may be clearly understood I will describe the same with reference to the accompanying drawings, of which- Figure 1 is a side elevation, and Fig.- 2 a plan, ofa machine constructed according to this invention. Fig. 3 is a longitudinal sectional elevation of the machine, showing the principal internal parts without the framing. Fig. 4 shows, on a larger scale, the mechanism for placing the wrappers and blocks of substance in the boxes or holders in which the wrapping is effected. Fig. 5 is asimilar View showing a block of substance and a Wrapper placed in one of the boxes or holders. Figs. 6 and 7 are elevations at right angles to each other of one of the drums which carry the endless chain of boxes or holders. Figs. 8 and 9 are similar views of the block-feeding device. Figs. 10, 11, 12, and 13 are views of one of the boxes or holders, drawn to a large scale, to more clearly show the construction thereof. Fig. 14. illustrates in side elevation, and Fig. 15 in plan, the device for applying paste or other adhesive material to the wrappers. Fig. 16 is a side elevation, and Fig. 17 a plan, of the rotary wrapper-folding devices; and Figs. 18 and 19 are similar views showing the folding devices in a more advanced position.

Referring to Figs. 1 and 2, 1 is the frame of the machine supporting a table 2, on which the folding devices are carried, the said frame or extension thereof carrying also the wrapper and the block -feeding mechanisms. Mounted in hearings in the frame 1 is the first-motion shaft 3, provided with pulleys 4,

around which passes a driving-strap from any suitable motor. Carried on drums 5 5 mounted in hearings in the frame 1, is an endless chain of boxes or holders 6, in which the wrapping of blocks of substance is effected. The wrappers in which the blocks of substance are to be inclosed are fed along a trough 7 by means of an endless band or chain 8, havingprojections 9 arranged at intervals to suit the size of, the wrappers and caused to project through and pass along a slot in the stationary trough 7, onto which the Wrappers are placed, so that as the endless chain or band 8 travels the wrappers are moved one at a time along the trough or table by each of the projections 9, the said trough or table being provided with ribs 10, which serve to guide the wrappers in their movement along the trough or table to between a pair of rollers 11, situated near the inner end of the said trough. The wheel 12, on which the endless chain 8 is carried, is driven at the requisite speed from the first-motion shaft 3 by gearing 13, as shown in Fig. 1. The lower roller of the pair of rollers 11 is rotated in its bearings by gearing 14 from the shaft of the adjacent wheel 12, which carries the chain 8 at a surface speed greater than that at which the said band or .chain 8 vtravels, so that the wrappers will be drawn from the band or chain 8 and allow the projections 9, by which they are fed forward, to pass clear of the said wrappers.

Each box or holder 6, as shown clearly in Figs. 10, 11, 12, and 13, comprises a bottom 6 and two upstandingsides 15, one of which sides 15 is hinged to the bottom, so as to be capable of turning outward, as shown by dotted lines in Fig. 10, but is normally kept in its closed position by a spring 16, thesaid hinged side having a projection 17, which at 0 the required times comes into contactwith a lever or projection 18, so as to open the hinged side to facilitate the entrance of a wrapper and block of substance to be inclosed therein, as hereinafter described. Each wrapper as jection 21 on each jaw coming into contact with an obstacle 22 while the chain of holders is traveling, the said jaw closing under the action of the spring onto the wrapper as soon as the projection 21 leaves the obstacle 22. The wrapper thus held in the gripping device travels with the chain of boxes or holders and in its passage receives on one end thereof paste or other suitable adhesive material from a receptacle 23-, in which is arranged to rotate a roller 24, driven by means of straps or chains 25 25 from the first-motion shaft The roller 24 is only partly immersed in the adhesive material, so that as it rotates it carries on its exposed surface afilm of the material, the thickness of which film is governed by a plate or scraper 26, suspended from a shaft or spindle 27, which is mounted in hearings in the frame 1 and rotatedfrom the first-motion shaft 3 by a chain 28, passing around the pulleys 23 .On the shaft 27 is an arm 29, carrying a brush 30, which as the spindle 27 rotatescomes into contact with the roller 24 and, removes therefrom a portion of the adhesive material and applies it to one edge of awrapper carried by the boxes or holders as the said wrapper is passing in contact with a support 31. The suspended plate or scraper 26 is slotted to admit of the passage therethrough'of the arm 29 and brush 30. A scraper 32 is provided against which the brush at each revolution comes into contact, whereby any superfluous adhesive material is removed from the brush and returns to the vessel 23. Each wrapper after receiving the adhesive material is carried by the chain of boxes or holders 6 into position in front of the feed-wheel 33 by which the blocks of substance to be inclosed are fed into the boxes or holders 6. When in this position, the wrapper is released from the gripping device and the lower end enters hooks 34 on a frame 35, carried by a rod 36, Figs. 4 and 5, the lower end of which rod is connected to a lever 36 pivoted at 37 to the frame of the machine, and carries a frictionbowl 35 which is acted on by a cam 39 on the first-motion shaft 3 to depress the hooks into position to receive the wrapper, the said hooks being raised by a spring 38 when the wrapper is to be inserted into a box or holder.

' The blocks of substance to be inclosed are placed on and carried forward by endless bands 37 preferablyrof steel, mounted on

drums

38 and 39 The shafts of these drums are carried in bearings in the frame of the machine, and the drum 39 is driven by a chain 40 from the shaft carrying the drum 5*, around which the endless chain of boxes or holders travels. The upper runs of the endless bands 37 travel in a slot in a table 41, secured to the frame of the machine, on the opposite sides of which slot ribs 42 43 are provided, which serve to guide the blocks in their movement toward the feed-wheel 33.

The front rib 42 is shorter than the rib 43 to permit of the blocks of substance being pushed from the table 4L onto the endless bands. The drum 39, around which the bands 37 pass, has flanges on each side, one of which has on its side a cam-surface or series of cams 44, which as the drum rotates acts on a lever or finger 44 so as to cause the free end' of the said finger to press upon a block of substance to retard its movement While the block immediately in front of it is moving forward to a stop 45, which stop is moved into and out of the path of the blocks at the re quired periods by cams 46, provided on the periphery of the other flange of the drum 39*. On the periphery of the barrel of the drum 39 are projections 47, which pass between the two bands 37 and in the spaces between these projections blocks of the substance are deposited from the bands'37 the movement of the stop 45 being so timed with reference to the speed of rotation of the drum as to ad mit of one block at a time entering into the space between each two adjacent projections. The blocks of substance deposited onto the drum are pushed by the projections 47 into a stationary trough 48, partially surrounding the wheel 33, from which wheel the blocks are fed into the boxes or holders 6.

The feed-wheel 33 is rotated by gearing 50 direct from the shaft which carriesthe drum 5 and which-is driven from the first-motion shaft 3. The feed-wheel is provided on its periphery with projections 51, which travel in the trough 48 and engage each block in succession and pushes them into position to be inserted into the boxes or holders 6 as the said boxes or holders come into position to receive them. The wrapper brought by the chain of boxes or holders into position to receive a block of substance is released from the gripping device carried by the box or holderin advance of the box or holder into which the block is to be inserted, the releasing of the said wrapper being effected by the projection 18, which also at the same time opens the hinged side of the box or holder which is to receive the wrapperand block of substance,as will be seen by reference to Figs. 4 and 5 of the drawings. The lever or proj ection 18 is carried on one arm of a bell-crank lever 52, mounted on a stud 53, the other arm of the said bell-crank being acted on by a cam 54 on the shaft 3, so as to bring the projection 1Sinto position at the required time for the

projections

17 and 21 to come into contact therewith to release a wrapper and open the hinged side of the box or holder into which the Wrapper and block are to be inserted. The wrapper having been released from the gripping device is supported on the hook 34, as shown in Fig. 4, in readiness to receive a block of material. The drum 5 around which the endless chain of boxes or holders passes, is fitted with radial slides or plungers 53 each having wings or projections 54 sliding in slots 55 in the sides of the drum,

. and each plunger carries a friction bowl 56,

which normally bears against a surface 55 concentric with the axis of the drum, to retain the plungers in their retracted positions, but which bowls as the drum rotates enter in succession a channel in a lever 57, pivoted to the frame of the machine. This channeled lever is connected by an arm 58 to the upper end of the rod 36, hereinbefore referred to, and operated by the cam 39 at the required intervals to move the channeled lever 57 forward when one of the friction-bowls 56 has entered therein and so cause the corresponding slide or plunger 53 to project through a hole 52 in the bottom of the box or holder (which happens to be on that portion of the drum) against the wrapper which is supported in the hooks 34. The feed-wheel 33 is also provided with radial plungers 59, having friction-bowls 60 on studs 61, which project from the plungers and normally bear on a stationary surface 62, concentric to the axis of the wheel. A channeled lever 63, pivoted to the frame of the machine and into which the bowls 60 enter in succession as the wheel rotates, is connected by an arm 64 and rod 64 to a lever 65, carrying a bowl 66, which is acted onat intervals by a cam 67, so as to move the channeled lever 63 when a bowl 60 is therein, so as to cause the corresponding plunger to project from the periphery of the wheel and force a block of substance which is held in front of the said plunger by one of the projections 51 against the wrapper against which a block of rubber 55 on the end of the slide or plunger 53 is pressing. The said block and wrapper being engaged between the

plungers

53 and 59, the frame carrying the supporting-hooks 34 is by the rotation of the cam 39 caused to rise, the plunger 59 being at the same time further projected by the cam 67, thereby pushing the wrapper and block into the holder,after which the bowl 56 on the slide or plunger 53 leaves the channel in the lever 57, whereupon the said slide returns by gravity to its normal retracted position. The plunger 59, which had forced the block and wrapper into the box or holder, is at the same time caused to return to its normal position in the wheel The wrapper, which is forced into the box or holder by the block of substance, surrounds the said block on three of its sides, the two opposite ends 68 69 of the said wrapper being caused by the sides 15 of the holder to stand up above the surface of the block. By the continued movement of the chain of boxes or holders in the direction of the arrows in Fig, l the partially-inclosed block is brought beneath a rotating folding device 70, carried on a shaft 70 rotated by gearing 71 direct fromthc shaft which carries the drum 5 This folding device, which is shown drawn to a larger scale in Figs. 16, 17, 18, and 19, consists of two sets of arms 72, secured on the shaft 70 on opposite sides of the chain of boxes or holders. These arms are arranged in pairs,.and between the outer ends of each pair is pivoted a folding-blade 73, which is normally maintained in a vertical position by a weight 74. This folding device rotates in the direction indicated by arrows, and as it rotates the weights 74 come into contact with a stationary curved bar 75, which causes each blade 73 to turn in its hearings in the arms 72, so as to angle each blade in succession, as shown in Figs. 16 and 18, and cause it to en gage the upstanding end 68 of the wrapper as it passes beneath it and press the said end down. onto the block. The rotation of the folding device is so timed with reference to the traveling movement of the chain of boxes or holders 6 that the folding-blades will act in succession on successive wrappers as they travel beneath them. The end ofthe wrapper thus folded down is that to which the adhesive material was applied, the surface which received the adhesive material being uppermost on the block of substance. The block thus partially inclosed by the wrapper passes next beneath a roller 76, by which the other upstanding end 69 of the wrapper is folded down onto the pasted surface of the folded-down end 68. The block is thus surrounded on. four of its sides by the wrapper and passes thence beneath a stationary plate 77, which holds the folded-down ends in contact while the laterally-projecting ends of the wrapper are being folded.

78 is a folding device for folding down the top portion of the laterally-projecting ends, the said folding device consisting of two sets of arms 79, projecting from bosses 79 fast on a shaft 80 and arranged on opposite sides of the chain of boxes or holders 6. This folding device is rotated by gearing 81 from the shaft carrying the folding device 70.

The arms 79 are arranged in pairs, and to each arm is hinged a folding-blade 82, the folding-blades of each pair being connected together by a spring 83, which tends to draw the blades together, but which permits of the said blades separating slightly to accommodate blocks of slightly-varying sizes. The inward movement of the folders is limited by stops 84 on' the said folders bearing on the bosses 79 of the arms 79. The rotation of the folding device 78 is so timed that each pair of folders 82 will act in succession on the laterally-projecting ends of successive wrappe'rs as they come beneath the said folding device. The chain of boxes or holders continu-ing to travel,the partially-inclosed block comes into position to have one side of each of the laterally-projecting ends of the wrapper folded in against the ends of the block. This folding in'of the rear sides of the wrappers is effected by folding devices 85, ar-- ranged one on each side of the chain of boxes.

These folding devices consist each of two arms 86, carried on avertical shaft 87, mounted in bearings in the frame of the machine and each provided with a bevel-wheel 88 in gear with corresponding bevel-wheels 89 on a horizontal shaft90, which is driven at the required speed from the first-motion shaft by the chain 25 passing around chain-wheels 91. To each arm 86 is fitted a block 92, which as the arms rotate in the direction indicated by arrows in Figs. 17 and 19 come into contact with the rear side of each laterally-projecting end of the wrapper and fold the said sides against the ends of the block of substance. The arms of each folding device act in succession on the successive wrappers as they come between the two folding devices. The folding-blocks 92 are fitted to slide to a limited extent on the arms 86 to suit packets of slightly-various sizes,the said blocks being pressed outward by springs 93. After passing the folding devices the remaining unfolded sides of the laterally-projecting ends of the wrapper come into contact with stationary blocks 94 and are thereby folded in against the ends of the block of substance, the lower tabs or parts of the laterally-proj ecting ends of the wrapper now only rem aining to be folded. These tabs are folded up against the ends of the block and'the wrapping completed by coming into contact with double inclined or helical surfaces 95, formed on cheeks 96, arranged on the opposite sides of the chain of boxes or holders 6 and between which cheeks the said boxes or holders travel. The completed packets are ejected from the boxes or holders by a forked lever 97, mounted on a stud 98, projecting from a bracket 99, bolted to the table 2. The arms of this forked lever have on their ends lateral projections 99 and on one of these arms is a bowl 100, which is acted on by a tappet-wheel 101, fast on the shaft of the drum 5, around which the chain of boxes or holders travel. The bowl 100 is maintained in contact with the tappet-wheel 101 by a spring 102. As each completed packet comes into position to be ejected from its holder one of the teeth or projections on the tappetwheel 101, acting on the bowl 100, raises the lever with a jerk so that the lateral projections 99 which are normally beneath the track of the packets, come into contact with the under side of the ends of the packet which project beyond the bottom of the box or holder and discharge the packet from the holder into a chute 103, by which the packets are conducted into a suitable receptacle.

It is to be understood that the operating parts of the machine are in constantmotion and the various operations hereinbefore described are being simultaneously effected on different wrappers in succession as they pass through the machinethat is to say, while the first folding operation is being performed on a wrapper the second folding operation is being performed on the preceding wrapper,

the third operation on the wrapper preceding that, and so on.
