I The present invention relates to winders for articles like sausage, hams, etc.

' i One object of the present invention is the provision of a machine for winding articles quickly, uniformly and tightly. 'A particular object is the provision of an automatically adjustable holder for different sized articles.

Still another object is the provision of means which facilitates removal of the wound article from the machine.

Another object is the provision of a spacing device for spikeswhich are presentjin the holder.

A particular object oftheinvention is the L provision of a holder having all the spikes re- V movable. r

Various other and ancillaryobjects and advantages ofthe invention will be apparent from the following description andaexplanation of the machine which is shown inthe drawings as an exemplary embodiment of'the:

invention.

such that a rotatable head stock presents a concentric and cylindrical cage of spikes having one free end each and a mounted end.

A ham, for example, may be placed in the cylindrical cage from the free-ends of the spikes. "A movable tail stock can be swung into axial alinement with the. holder containing the ham and can be moved toward the holder to receive the free ends of the spikes,

thus holding and guiding them. A lead screw carries a guide for winding cord and feeds cord along the held ham. The device in the head stock is so arranged that when turning is commenced, the holder automatically tightens and squeezes the ham.

The various functions of the essential parts generally referred to above may be efiected by:numerousconstructions. In thedevice ofthe drawings there is shown by way of illustration .one mechanism for performing the various functions. Certain detailed devices with special functions are also employed. It is to be understood that the invention is not to be considered as limited to the specific devices herein disclosed and described, but it is to be considered as more comprehensive ,in scope and to include modifications and changes falling within the scope of the appended claims. I

I prefer to mount the machine on a table 10 rigidly supported by legs 11. The machine has abase 12 secured by bolts 13 entering lugs 14 in the dished underside of the base. On thebase (Fig. 1) at the right, there is a fixed upright support 15 for the head stock; at

the front, two fixed upright brackets 16 and 17 and a covering connecting hood or shield 18 for the'cor'd feeder and carrier; and at the rear left, two lugs 19 and 19a for mounting the tail stock.

The headstock is carriedby an axle hearing in upright '15-; Anypower means,

such as a hand crank 2l turns the machine.

Onthe inner end ofthe axle 20 there is a drum 22 keyed at 23 to the axle. A gear 24 is formed by teeth on the drum for operation offlthe cord feeder.

I illustrate a lock in the form of aspindle 7 4 with handle 75 so that the spindle maybe turnedto fb-ringa key 76 intolocking position between the teeth of either gear 24 or gear 73.

In use, it will be obvious that the spikes I 30 andthe article therein, are tightly wound. It is necessary to withdraw the article from 19 the holder, causing the spikes to slide betweenthe windings and the" article. Much difliculty is experienced, especially with long small articles, like summer sausage. A great deal of force is required to draw the article 7 off the holder, and muchtime is wasted. To

avoid this I make some, but preferably all, of the spikes 30 removable from spike carrier lugs 34; In practice I find that three l fixed spikes and three removable spikes per V miteasy and convenient removal of an arti- 1 cle. .However, in order to make the machine .more adaptable, I'prefer to provide all the spikes as removable spikes, and to provide means for rendering them fixed as desired. I may do this by inserting the spike removably into asocket in lug 84 (Figs. 9 and 10). v A groove 80 in the spike receives the end of a set screw 81 in socket 34 to lock the spike in the socket. When the screw is loose, the spike is a removable one. In addition I provide a collar 82 on the spike. This may be used conveniently over a shoulder to aid in drawing a removable spike from a wound article. 7

. By having all thespikes removable, and

byproviding a large supply of spikes, the capacity of the machine may be greatly increased. With fixedspikes considerable time is wasted in removing a wound article from thespikes. It must bemoved over the length of the spikes and this motion is not quickly accomplished. With removable spikes, the wound artic'leand the spikes need be moved only arelatively short distance. A second workman may, remove the spikes, and as spikes are placed into the machine for a new piece, they may be selected and positioned according to the piece to be wound. removing one'or more spikes with the article,

the effort in removal is lessened, and there is a lessened tendency for spikes to move the windings, The particular method of operation may be adapted to the character of article, and the character of winding.

I claim 1. A winder for articles such ashams andsausage, comprising in combination, a base plate, a head stock therein, a removable tail including spaced means to engage the free ends of the spikes individualy' in a fixed spaced relation for rotation therewith.

2. In a winder of the class described means for holding an article tobe Wound comprising in combination, a rotatable head having a whereby one or more spikes may be removed with the wound article, and a concentrically mounted revoluble funnel-shaped receiver for the free ends of said spikes.

4. In a holder of a winder of the class described, in combination, a spike carrier having receiving means adapted to receive a spike axially, a spike having an end adapted to be removably mounted in said means axially of the spike, and means for positively holding said spike in said carrier against removal.

5. A holder for a Winder of the class described comprising incombination, a series of spikes arranged as elements of a cylinder, and a carrier for said spikes having means cooperating with the end of each spike to mount it in position, at least one spike being removable from said carrier.

6. A holder for a winder of the class described COIHPI'lSlIlg. in combination, a series of spikes arranged as elements of a cylinder,

a carrier having means for mounting each of said spikes for removal of each spike, and

means for looking at least one of said spikes into the carrier against removal.
