Application led May 23, 1921i.
My invention is particularly adapted and intended for applying elastic jackets to joint meats, such as hams, shoulders and the like, and hereinafter is more particularly de- 5. scribed with reference thereto. However, it is also adapted withobvious modifications to apply flexible coverings to a great variety of Yother articles. lhen used for the purpose of covering hams and similar joint meats',
the jackets may be applied either before or after the meats have been smoked and the jackets may be of elastic material such as stockinette, or relativelyinelastic material such as muslin. rlhe machine is especially "useful, however, in applying jackets of stockinette or the like to the joints prior to smoking, in accordance with the patent to Fitcgerald No. 1,122,715. According to the process ofthis said patent, the hams or other joints after-being pickled and before fur *her treatment, are encased in close fitting bags made of elastic fabric, such as stockinette, and then smoked lin substantially the usual manner, after which they are ready for the market without further handling. The jacket is preferably prepared as a bag or sleeve, having one end closed and the other open, and after the ham is inserted, the open end is closed by sewing, knotting, or otherfor applying jackets of this character. By the use of my machine a great saving is effected inthe time and labor required to encase the hams in their jackets, the latter ai are evenly applied to the joints so that after the jacket is closed and in the smoking operation even pressure is brought to bear upon the softer parts of the meat by reason of which the finished joint compact and U rounded and presents an attractive and merchantable appearance. Y The form of the invention hereinafter described comprises a pair of guides for the joint 'over the ends of which the open jacket is stretched and power operated plunger' by which the joint is pushed between the guides and into the bag or jacket. The guides are pivoted at their rear ends and converge or approach each other toward the bag holding 5* ends thereof. fis the joint driven forward the guides swing outward away from 'each other under the pressure of the ham, distending the jacket so that the ham may readily enter the same, irrespective of its size, and
wise. My machine is particularly designed Serial No. 715,336.
the movement of the guides actuates a counter or counters so that tally is kept of the number of joints jacketed. @ther features and advantages of the present invention will appear from the following cetailed description thereof. lt is to be understood, however, that the specific disclosure is for the purpose of exempliiication only and that the scope of .the invention is defined in the following claims in which l have endeavored to cover it as broadly as possible in view of the prior art as known to me.
In the 'dran/*ings accompanying and forming a part of the specification, Fig. l is 4an isometric view of a preferred embodiment of my invention; Fig. 2, a front elevation thereof; Fig. 3, a plan partly in horizontal section on the line 3 3 of Fig. Ll; Fig. li, vertical transverse section on the line /i of Fig. 3; Fig. 5, a transverse vertical section on the plane of the line 5 5 of Fig. 3; Fig. 6, a horizontal plan partly in section on the line 6 6 of Fig. i; Fig. 7, a vertical longitudinal section of a detail, partly broken away and partly in elevation; Fig. 8, a transverse vertical section of another det-ail; and Fig. 9 is a cross-section on the line 9 9 of Fig. 3. A
Each part is identified by the same reference character wherever it occurs in the several views.
The mechanism of my invention may be mounted in any suitable manner and l have shown it as supported upon a table or stand l1, the specific construction of which it is unnecessary to describe. Thev swinging guides for the meat to be packaged are shown at l2, 13, the plunger for forcing the joints forwardly between the guides at il, and the counters to which reference has been made, at i5, i6.
The swi-i'iging guides l2, 13, are of similar construction and shape, comprising each an elongated interiorly convex portion l?. which, at its forward or free end, is formed with an upwardly extending wing 18, the
two wings on the respective guides sul` stantially coming together when the guides are in normal closed position, as best shown in 2. As shown in Figs. l and 3, the nozzle formed by the guides extends beyond the front edge 19 of the table, so that. the wings 1S are clear thereof and the table is provided with a bottom guide or exten rounded torni at its end, as best shown in Fig. 3. The side edges of the bottom guide V2() are formed with downwardly projecting flanges or ribs 2l (see Fig. 9) to hold the lower edge ot a bag on the guides well away from the top surface ol the lower guide. In using the machine, the-bag' or container is slipped over the nozzle formed by guides l2. 13 and 2O preferably until its forw. edge or mouth is at or beyond the rear edm Q2 of the wings 18, so that the operator may readily hold the bag,r in position while the ham or other joint is being slipped into it. The rear ends of the respective swinging;- guides are formed or provided with sleeves 23, which receive the stationary pivot pine; Q4, thus providing for the swinging move-A ment of the said 0fuides. The sleeves 23 eff the swinging guides are 'formed or provided with rearwardly extending,r arms 26, Q7 from which extend inwardly and into the path ot the plunger 14, arms 28, 29. As the plunger returns to normal position it engages said inwardly extending arms, forcingr them rearwardly, and thus closes the swinging guides. The inner ends ot' arms 28, 2O are connected by links 30, 81. to a central sliding guide 32. The latter slides in a sleeve 33 oit a bracket 34 bolted to the table at the middle thereof. In the preterred construction shown, the guide 32 is formed with a flattened head and the links 30, 3l, are pivoted on a pin 35 extendingr through sa flattened head, the link 3l being above an the link 32 below the same. The inner ends ol" links 30, 3l, are faced ott at an acute angle to the length thereof, which angle is similar in the two links so that when the swinging guides are in their closed or normal position, as shown in tull lines in Fig. 3 and in Fig. 6, and consequently the holt 32 is `n its rearmost position, the ends ot the links rest against` the flat front face 37 of the guide and therefore the guides l2, 13, are accru., ely positioned over the guide 2() in their closed position with their meeting` edfes directly over the center line of seid guide 20. By reason of the constiet n just described, the swinging guides are always moved an equal distance trom the median line of the machine so that the aclc et on 'the nozzle termed by the swinging; guides and the stationary guide beneath them and the joint as it inserted therein are always in proper position and symmetrically placed with reference to the machine.
.in the preferred form of the invention herein described, the plunger la by which the meat joints are pressed or moved through the noir/.le termed by the guides and into the jacket, is operated hy a pneumatic cylinder, though obviously oth r means might he employed for the purpose. The cylinder 38 of the pneumatic motor is supported in a bracket 39 on the top of the table or stand and it may he of any suitable or usual construction. ln the forni shown it is provided with an air pipe --O leading to the rear end thereof, and an air pipe 4l communicating with the trent yend ot the cylinder throne-h a casting;- lf2 which closes the front end oit the cylinder. shown at and the rod thereof extends 'hrough the packing hoK 45 at the front il of 'the cylinder and carries the plunger ris heretofore stated, the piston rod elle Ride-il in die las. f' which is 'ern'icd he controlled by any usual or al'iproi'ed fc systen'i, and l have shown the supply a a0, `il connected to a rotary valve 4T Lamine for this purpose. Valve 47 is pro vided with an inlet port 48 connected-hy pipe l Jl-9, 50, with a suitable source of co1- pressed air and an exhaust port 5l. By
rotating the valve plug the supply of air and exhaustcan be alternately connected to the respective ends of the motor cylinder. lt is convenient to operate the valve plug' by means oi' a pedal or pedals, leaving the hands of the operator or operators free to handle the jackets and joints. For this rpc-se l have provided the valve plug' 'h an operating arm 523 and a pair ot pedals 5a, 55, arranged on opposite sides et the front of the machine and connectefil to the arm 53 so that the machine may be operated from either side, and it desired, by." a pair ot operatives working it alternately. The pedals 54, 55, are pivoted in brackets 5G, 5'?, and the inner arms 5S, 59 ci? tee pedals, which are sli;V aj ott-set with re spect to each other, are pivoted to the respective links GO, Gl, the upper ends ot which are pivoted to arni 5P) at G2.
