In an embodiment of the present invention, the carrier 1 isjitself oft-angle formae tionhavinga connecting web 2' across the limbs,.thereby comprising a corner element; whereinetheboxucant-be quickly placed and removed with its base" against the web 2 and: two of itswallsi'adjacent the limbs of the carriers Theweb 2 maybelaterally adsjustabletoaccommodate the carrier to boxesof different depth, this :being: conveniently provided for by slotted armsfi on. theweb engaging screw clamping rmeansjvl 'onl the carrier 1.1-: A rubber edgingb is, counters sunk along the. edges of the limbs of the carrier 1 remotefromthe web. This 'carrier liquely set frame 6 adapted atov slide inthe hold a series of'emetalifingers 12,.

A slidablelL-shaped frame llcorresp onding somewhat, to the ,fixed 'L,-shaped frame 9 is mounted alongside that member,v and, coinprises two clamping; elements adapted to y employed, according to the length. and

breadthof the box, and. are adapted to: be carried. .by the vertical. as wellas, the hori- 1 gent-a1 limbof;.thepart 11. -.Their,extre1ni-;

ties 13 maybe shaped according tothe tasks they have to perform, ,foriexarnple that finger at the corner may, be shaped 'd-iiferentjly to the adjacent Lone's, operating on the flat. fTliek-sliding frame 11 rnay;be carriedby abase lwhich has a slidingrelationship with thetop or table part 15 ofjthe structure 8. a Th fingers may be readily I interchange f ablefandQtheir outer; or operative extremities normally terminate substantially flush with 1 the edge ofthej carrier 1; Itjwillgbe noted n r fere e to .F gu Q that one s de OI- ofjthebox carrier 1 and also of 'the finger carrier frame 11i is vertical and the other side horizontal; and" that the guide framejfi and guides are inclined at anangleof so 'that' the bo carrier which is caused; to

niovewith theframe 6 laterallyQWith respect t'o'itself main ap lanewhich isat an equal angle to each of 'saidfsides, iif tlie box carrier and finger oarrieraiidliencethe fingers are arranged for relative movement to the same extent toward and from the two sides of the box carrier between movements of the latter and its frame 6, Both carrier 1 and slidable frame 11 are adapted to be actuated from a suitable power shaft 16 (Figure The power shaft may have an eccentric on it which rocks a lever 18 on a v pi ot. .9, andni on e tedby a rod 20 to the slide 14 carrying the slidable frame 11. The

,cam slot 21 ,is so shaped that when the fingers 12 are dra'wn home towards the box carrier 1, there is a period of rest. during which such carrier is reciprooated for the pressing or completing operation of the turnover. Further, a ;suitable cam 22 on; the power shaft 16 may operate one limbv of, a

bell-crank lever 23, the other limb of which is attached toa second bell-crank lever 2& (see particularly Figure 5.), adapted to actuate theslide 6 ofthe carrier 1. i y

The power shaft 1.5.,may1be driven e f r a pulley 25 by way of a. one rev0luti=onclutch 26 (Figure 1-) operable by foot mechanism,

27 or 7 suitable hand. mechanism. Such a one revolution clutch is Well lniownin box making and like machinery :andl ensures the carrier'l. and member ll always assuming, the position lllLlStliLtGClNVllGn the clutch is thrown open.

The timing of the parts is such that" the slidable; frame 11, is firstly moved jtowa'rds r the carrier 1, the fingers passing, over the side wall against the :base'; or horizontal limb, During the operation of placing or positioning the box the projecting paper edge is brought into contact with the ex; tremities 13 of the fingersan'd' is bent substantially at rightangles tothe wallofthe box, The apparatusis then 'sje't; in operation,- the slidable frame '11 causing thefing'ers ion web and end wall 7 to move the already bentpaper edging i'n V wardly,' folding vit" on to the inner face of he box, the cip c ry .mo m ntofflw carrier. 1 securelysealing i't5 and the fingers are then withdrawn. In this; manner two edges of the box are-finished 'and the: other two are-then operated on in aisimilafr manner. Thefingers are automatica'llycleaned 1 asthey'pass over thegroove 10; On'account ofthe'; open nature of the carrier, 1', boxes can be very speedily placedinflpositioii and removed'bythe operator. 1 I claim as. my inve tion and ldesire to" secure by Letters -Patent-"is: i

angularly related sides, a relatively fixed wiper element, a finger carrier having angularly related sides corresponding with those of the box carrier, fingers carried by said sides of the finger carrier, means to move said finger carrier toward and from. the box carrier longitudinally thereof so that the fingers pass over the wiper element and partly over the box carrier, and means to impart relative reciprocating lateral movement to the said carriers to cause said lingers to move toward and'from said sides of the box carrier. 3. In apparatus for covering boxes, a bo carrier open on one side and .having angularly related sides, a relatively fixed wiper element, a finger carrier having angularly related sides corresponding with those of the box carrier, fingers carried by said sides of the finger carrier, means ,to move said finger carrier toward and from the box carrier longitudinally thereof so v that the fingers pass over the wiper element and partly over the box carrier, and means to impart lateral reclprocatmg movement to the box carrier to cause said sides thereof,

to move toward and finger carrier. r a

4. In apparatus for covering boxes, a box carrier and a finger carrier each having two angularly related sides, said box carrier befrom the fingers of the 7 ing arranged. for lateral movement toward and from, the finger carrier in a plane, which -atan equal'angle to each of said sldes of said finger carrier, said finger carrier 7 being arranged for longitudinal movement toward and from the front end of the box carrier to pass the fingers partly thereover and withdraw the same therefrom.

5. In apparatus'for covering boxes, a box carrierand a finger carrier each having two angularly related sides, said box carrier bemg arranged for lateral movement toward and from the finger carrier in a plane which is at an equal angle to eafch'of said sides".

' of said finger carrier, saidfinger carrierbeing arranged for longitudinal movement toward and from the front end of thebox carrier to pass the fingers partly thereover and withdraw the same therefrom, and a wiper'arra-nged for contact with said finger during such movement of 'thelatter.

6. In apparatus for covering boxes, a

supporting, frame, a box carrier open on one side and having angularly related sides, O V

means mounting said boxcarrier on said frame for lateral movement of said carrier ,in aplane at an equal angle to each of saidsldes of said carr1er, means to lmpart such movement to such carrier, a wiper element mounted on said frame and arranged at the front side of said box carrier, alfinger carrier having angularly relatedf sides correspondingto those'of said box carrier,

fingers on said finger carrier, means mount lng said finger carrler 'on said frame for,

reciprocating movement of said finger,

carrier toward and from said wiper and the l front side of said box carrier to "pass said fingers over and from saidwiper and said sldesof the box carrler, and'means to impart such movement to sa1d finger, carrler'.

.7. In apparatus for coveringboxes, a 'box' carrier element and a paper edge turning element,said elements being arranged for relative lateral movement and also for rela-' tive movement longitudinally over said box carrier element and meansto impart such movements successively to such elements.
