Specification of Letters Patent.

Patented July 25, 1916.

To all whom it may concern:

Be it known that I, JOHN G001), a citizen of the United States, and a resident of the borough ot-Brooklyn, county of Kings, city and State of New, York, have invented certain new" and useful Improvements in Hackle-Chain Apparatus, of which the following is a full, true, and complete specification. I

The invention relates to hackle-chain apparatus used in long line combers andallied machinery, and has for its objectto improve the construction and operation thereof in a number ofparticulars.

The machine is'adapted for working. the commercial grades o1 hemp,jute, and fibers of substantially the same length, being made heavierrfor longer fibers and lighter and with more pins for shorter fibers. I

The improvements aifect more especially, though not necessarily exclusively, those forms of such apparatus wherein I two or more chains driven at different speeds are employed in series, important objects being to make possible a very short nip upon the fiber at proximate ends of the chains, and at the receiving end to secure. the benfits of direct penetration heretofore obtained in the relatively slow and less desirable gill-box type of apparatus. These and other advantages of construction and operation are obtained by the improvements which will now he described, comprising particularly certain features of construction, combination and relation in respect to the dogs and trackways for controlling the rake of the gill-pins and the means for guiding thechains through their courses. I

In the accompanying drawings: Figure 1 is a side elevation, showing proximate portions 01' two chains; Fig. 2 is a planview of Fig. 1, the apparatus being broken away centrally and longitudinally for economy of space; Fig. 3 is a vertical cross-section on the line 33 of Fig. 1, the apparatus being broken away centrally as in Fig. 2 Fig. 1 is a vertical longitudinal section on the line 11 of Fig. 3; Fig. 5 is a vertical longitu dinal section on the line 5-5 of Fig. 3; Fig.

6 is a vertical longitudinal section on the line 6-6 of Fig. 3; Fig. 7 is a vertical longitudinal section on the line'77 of Fig.3, Fig. 8 is a section on a larger scale, taken on a vertical longitudinal plane at the receiving end of one of the chains to illustrate the manner in which the chains and dogs are being driven at a relatively lower speed and delivering the fiber to the chain 2, which operates at a relatively higher speed. For convenience the chains will be referred to as the low speed and high speed chains, respec tively, it being understood that these terms l are used relatively. The driving connections whereby the difference in speed is secured are not illustrated, as this feature of Operation is familiar tothose skilled in the art. The framework may be made, insections, corresponding to the length of the chains, and joined at their proximate ends, as indicated atB. The frame section including the low speed chain 1 comprises two side plates 4: and 5, united by suitable cross-members, represented by the beam 6. Similarly, the frame of the high speed chain 2 comprises side members P and 5 and crossmembers including the beam 6 The chain 1 comprises a series of parallel gill-bars 7 bearing the usual gill-pins 8 and mounted rotatably at their end portions in two parallel series of links 9, the chain being preferably of that type of construction in which the gill-bars are independent of the joints of the links, so that the bars are not subjected to the pulling strains, which are transmitted only from link to link. The construction indicated in Fig. 3 is that disclosed in my Patent 1,048,526 of December 31, 1912, wherein every alternate link is provided with a boss 10inserted within the eye ofthe adjacent link, which thus forms a. link joint, and the gill-bar is mounted or journaled inside of the boss, which is tubular for the purpose.

Means for guiding the work or upper stretch of the chain 1 comprise spaced parallel lower and upper rails 11 and 12,.of which the rails 11 rest on cross-beams 6, while the upper rails 12 are supported from overhanging brackets 13, thechain guides" 7 plates is fashioned with a guide flange 16,

which is advantageously of substantial width and comprises, as shown in Fig. 5, an approximately straight top portionoverlapping the terminal portion of the rail 11 and leading to a curved portion at the delivery bend, which curved portion merges into a straight downwardly inclined portion leading in turn to a curved portion at the return bend. The extremities of the guide flange may be additionally incurved, as shown, for the purpose of insuring easy entrance of the guided parts in either forward I or backward driving of the chain; The terminal portions of therailsll and 12, which extend substantiallyto-the delivery bend, are curved for a similar purpose, as shown in. Fig. 6. Inthe vicinity of the return bend the plates 14L are supplemented in their duty of guiding the gill-bars by guide flanges 17 disposed vertically below' the fianges'l6 and carried by plates 18, having bracket portions 19 supporting them in inwardly spaced relation from the side frames. These guides conduct the chain for a suitable distance beyond the return bend, from which point onward the return stretch of the chain may be guided or unguided as preferred. The construction at the opposite end of the low speed chain 1 is not illustrated, since it may be like the receiving end of the high speed chain 2 or of other character without affecting the invention. The chain is further guided at the delivery and-return ends by upper and lower pairs of carrying wheels 20 and 21. The shafts 22 and 23,0f these wheels are journaled inbearings 24. and 25 in the plates 1th, and are consequently spaced at their ends from the side frame'so as to permit the passage of the arms of the dogs 30, which mayv be made of considerable length. The wheels may have either plain or notched peripheries, both being known in the art, but are preferably plain and'are of different diameters, the upper wheels being substantially smaller than the lower because of the desirability of securing a sharp bend in the chain at the point where the gill-pins fall out of the fiber. The driving of the chain may be effected by wheels 26 having teeth engaging the gill-bars inside of the chains, these wheels being mounted on a cross-shaft 27, which inFig. 1 is indicated asbeing driven from a longitudinal shaft 28 through gearing 29.

The dogs 30 are fixed on the ends of the gill-bars outside of the links, their purpose being, as iswell understood, to cooperate with suitable grooves or trackways to control the rake of the gill-pins, more especially throughout the working stretch and while rounding the ends of the circuit. Each dog comprises a hub 31', which receives the end of the bar, and two arms 32 and 33, which may be termed the main and auxiliary arms and which cooperate at different times with main and auxiliary trackways presently to be described' In my prior Patent, No. 1,048,526, mentioned above, there is disclosed a dog having arms disposed, as here, in substantially right-angular relation to each other, and extending obliquely to the x axis of the gill-bar. I however, the inclination of both arms was laterally outward, whereas in accordance with the present inventionthe armshaverevers'e'inclinations, the arm 32 being inclined laterally outward and the arm 33 laterally inward, from which construction and rela tion important benefits accrue, as will presently appear. The extremities of the dog arms are provided with cylindrical bosses 3st and 35, which in therpresent invention project in opposite directions, the bosses of the outwardly inclined main arms being directed outward and those of the inwardly inclined auxiliary arms extending inward, with respect to the side lines of the chain. I

The main trackway, in which the bosses at are guided, comprises plates 36 applied to the inner faces of the side frames and formed with guide grooves 37 extending in or adjacent the horizontal plane of the working stretch of the chain guideway, so that during the forward travel the main arms 32 trail more or less directly behind their gill- In that construction, t

bars, the auxiliary'arms 33 and the pins 8 wardly and inwardly directed bosses 34 and 35 of the'main and auxiliary arms, respectively. The auxiliary trackways are suitably formed to conduct the dogs around the delivery and return bends and through the downwardly extending stretch connecting the same, in such manneras to cause the pins to pass downward out of the fiber substantially vertically, and thereafter to prevent interference between the dog arms, as indicated in Fig; 4:. The upper portions of the auxiliary trackway .Q'uides overlap the main trackway guides of the working stretch, and their lower portions extend rearward for a suitable distance in the direction of the return stretch. After the bosses 35 of the auxiliary arms of the dogsleave these lower portions of the auxiliary trackway guides, the dogs may be unguided while traveling through the return stretch, or guides similar to the guides 41 of the high speed chain 2, presently to be described, may be present to receive the bosses 34 of the main arms to conduct the dogs through the return stretch to such receiving and guiding means as may be provided at the remote end of the circuit.

The high speed chain 2 is in all substantial respects like the first chain, from which it receives the hemp, and comprises the bars 7 a with pins 8 and the links 9, in which the ends of the bars are pivotally mounted. The dogs 30 of this chain resemble the dogs of the first chain, having main and auxiliary arms 3 and 33 with bosses 34 and 35, respectively. The relations may differ, however, to the extent that the pins 8 are inclined slightly forward with respect to the auxiliary arms The chain guide rails 11 and 12 correspond to the parts 11 and 12 heretofore described and are indicated as be ing similarly supported. The main trackway guides, for controlling the dogs during their t "avel through the working stretch, are designated 36, and il are trackway members which guide the main dog arms through the return stretch to the receiving end of the circuit. The chain is guided to the receiving end of the circuit on the flanges 17 of guide members 18 similar in general re spects to the parts 17 and 18 adjacent the return bend of the low speed chain. At the receiving end 01". the circuit of the high speed chain, however, the gill-bars are carried and guided by a single pair of wheels 43 mount ed on a cross-shaft 45, the ends of which are mounted in side frames 4F and 5 since at the receiving end of the circuit, owing to the disposition of the dogs, it is not necessary to provide for clearance of the shaft by the arms as is the case at the delivery end. The auxiliary trackway guides 38 are mounted in a manner similar to the auxiliary tracle way guides 380i the low speed chain, and guide the auxiliary arms 33? during the travel of their gilhbars around the wheels d3. It will be observed that, owing to the reverse lateral inclinations of the two arms of each dog in both of the chains,it'is possi ble for the inwardly inclined arms 33'of the low speed chain to pass in overlapping rela- 7 tion the outwardly inclined arms 32 of the high speed chain, thus enabllng the proximate ends of the chain to be brought very close together, with the consequent advantage of a short nip upon the fiber. The main arms 32 of the low speed chain are inclined outward rather than inward, in order to secure the benefits. of long arm action, these arms being, as indicated, substantially longer than the spaces between the gill-bars, and because of their outward inclination being free to overlap each other to as great an extent as may be desirable. The same advantage flows from the outward inclination of the arms 33 of the high speed chain, and in addition these arms are enabled to pass the inward inclined auxiliary arms 33 of the low speed chain, as just described. While the auxiliary arms 33 of the high speed chain might be inclined outward, as in my prior Patent, 1,048,526, above referred to, as far as the function of insuring a short irip is concerned, it is advantageous to have them extended obliquely inward like the auxiliary arms 33 of the low speed chain, because this relation enables the auxiliary trackway 33 to overlap the main trackways 36' and il in the crossing relation shown in Fig. 4:, this being possible because the main and auxiliary trackways are laterally spaced with respect to each other. The crossing relation of theitrackways at the receiving end of the high speed chain is important to the proper control of the dogs, and thereby of the bars and gill-pins. Manifestly the same relation may obtain in the low speed chain.

The organization of the chain and dogguiding means at the receiving end of the high speed chain is such as to secure substan tially direct penetration of the fiber by the pins in the manner represented in Fig. 8. It will be observed that the trackway guides 38 for the auxiliary arms of the dogs are formed with curved portions is, which may be approximately concentric with the axis of the wheels and disposed at such distance from their peripheries that the gillpins as they rise and approach the hemp line assume a forward inclination, which inclination they possess when their extremities enter the fiber. At this point the bosses 35 encounter portions 47 of the trackway groove which are substantially vertical or inclined slightly forward and which compel the upper portions of the pins to rise. substantially straight upward through the fiber, while their hubs attached to the gill-bars are being carried'upward and forward around the wheels, the pins thus straightening as they. rise. The portions 47 of the trackway grooves are of such length that when the successive bosses 35 reach the upper ends of the said portions, the corresponding pins have assumed thesubstantially erect posis tion shown at the left of Fig. 8. From this point onward fora short distance the bosses 35? of the auxiliarvdo arms travel throu h forwardly extending portions 48 of the aux- I the precise construction shown, and that numerous changes may be made without departing from essentials. lfiurthermore, while the invention is primarily an improvement in hackle chain apparatus, the dog herein described need not as a matter of use be limited to such mechanism solely and ccrtain of the appended claims are designed to cover the same and its relations for other kinds of chain devices.
