FEEDING MECHANISM FOR BOLT-MACHINES. i
Application led December 16, 1919. Serial No. 345,283.
To all whom t may concern:
Be it known that I, HANsoN THOMAS, a citizen of the United States, and resident of Pittsburgh in the county of Allegheny and State of Fennsylvania, have invented a new and useful Improvement in Feeding Mechanism for Bolt-Machines; and I do then removin hereby declare the following to be a full, clear, and exact description thereof.
My invention relates to feeding mechanism for bolt machines.
The object of my invention is to provide a simple and eicient feeding mechanism for bolt machines by means of which the bolt may be pointed at one position and then automatically moved into a position for threading and nutting, so that the operations heretofore followed of pointing and the bolt from the pointer and placing it manually in position for threading or nutting is avoided, and the operations performed quickly and in succession, thereby greatly reducing the time and labor.
To these ends my invention comprises the novel features hereinafter set forth and claimed.
In the accompanying drawings, Figure 1 is a vertical elevation of my improved feeding mechanism showing the threading and nutting device partly in section; Fig. 2 is a view taken on the line 2 2, Fig. 1, showing the bolts in position for the pointing and threading operations; Fig., 3 is a like View showing the bolts in process of being moved from one position to another; Fig. 4 shows a modified form of my invention; and Fig. 5 is an enlarged section on the line 5-5,Fig. 1.
In the drawings, the numeral 2 designates a suitable support upon which is mounted the housing or frame 3, in which is journaled the shaft 4. Mounted on the shaft 4 is the gear-wheel 5 which meshes with the pinion 6 mounted on the pointing spindle 7. The pointing device 8 is of any ordinary construction provided with the pointing knives 9, and as this pointing device forms no part of my invention, it has not been deemed necessary to illustrate and describe the same in detail.
Below the pointing device 8 and mounted in the housing 3 is the rotary die-head 10 specification of Letters Patent.
. therefore, not
Patented Sept. 6, 1921.
which carries the thread-chasers 11. This rotary die-head has not been illustrated in detail as it is complicated in form what is known as the Landis rotary diehead, well known to those skilled in the art.
Combined with this Landis rotary diehead 1s a nut-feeding mechanism which comprise'sa nut-magazine or barrel 12- contained within a sleeve 13. Suitable mechanism is provided for feeding the nuts 14 one by one, and this whole device has already been patented 1n a patent issued to Henry Oliver,
o. 1,282,116, dated Oct. 22, 1918. It will, t be necessary to illustrate this feature in detail, as it forms no part of my invention.
Mounted on the support 2 is the baseblock 15 provided with the guide 16 in which the frame 17 is adapted to move back and forth, said frame being mounted on the sliding block 18 fitting in said guide. The frame 17 is bolted to said guide by the bolts .19 andl said frame has the T-head 20 fitting in a like shaped groove 21 in said slideblock 18.
A lever 22 is pivoted at 23 to the base 15 and said lever engages a pin 24 on the slide-block 18 whereby said slide-block may be moved forward by said lever for the purpose hereinafter more fully set forth..
A spring 25 is connected to the lug 26 on the slide-block 18, and at its opposite end to the stationary base 15, said spring acting to normally hold the frame 17 in the position indicated in full lines Fig. 1.
Frame 17 has the vertical runway 27 to receive *he bolts 28. At the upper end of the runway 27 is the magazine 29 from which the bolts are fed one by one to the runway 27. In order to support the bolts at the proper position for the pointing and threading operations, I provide the fingers 30 and 31. The ngers 30 are mounted on the rocker-shaft 33 mounted in the frame 17. lIhe arm 32 is connected to the rockershaft 33. A rod 34 is connected to the arm 32, the lower end of said rod being connected to thel arm 35 on the rocker-shaft 36 mounted in bearings in the frame 17. The fingers 31 form part of the detents 37 which act to detain the bolt at the position indicated in Fig. 3 before said bolt finally drops on to the lingers 3l.
and is v l A spring 38 is co' ected to the rdd 34 and to the frame 17, aid spring acting to hold the fingers 3() and 31 normally in the position indlcated in F 1g. 2.
5 A trip-finger 39 is connected to the rockershaft 36, said trip-finger being adapted to engage the pawl 40 pivoted at 41 to a'lug 42 on the stationary frame V17 advances the tmp-fin er 39 will pass beneath the pawl 40 whlch will be raised thereby, and upon the return of said frame said trip-finger will ride up on said awl and so act to rock the rocker-shaft 36 ihr the purpose more fully hereinafter sct forth.
Slots 43 and 44 are formed in the runways 27 to allow the fingers 30 and 31 to project into said runway, and for their movement therefromto permit the bolts to drop through said runway. Y
In order to retain the bolts in the magazine 29 and to feed the same one at a time to the runwa 27, I provide the dogs 45 mounted on t e rocker shaft 46. An arm 47 on the rocker-shaft 33 has the pin 48 which engages a slot 49 in an arm 50 secured to the rocker-shaft 46. The dogs 45 have the recesses 51 formed therem.'
At the pointing position of the bolt 1 n .the frame 17, I rovide means for permittlng the bolt to yield longitudinally during the pointing operation to prevent undue -strain, as well as provide for 'variations 1n the length of the bolt. Accordingly- 1n the frame 17 I provide the seat 52 to .recelve the age-block 53 which bears at its forwardI end against the head 54 of the bolt. A spring 55 is interposed between said gageblock and the inner wall-56 of the' seat 52. An adjusting screw 57 may be employed for adjustin A slot 58 1s formed in the gage-block 53, and a pin 59. on the frame 17 enters said slot to control the movement of the gage- 45 block 53.
' A chute 60 is rovided to receive the bolts as they are delivered from the lower end of the runway 27 to discharge them into a suitable receptacle below.
In the operation of my improved feed mechanism as illustrated in Fig. 1, the bolts supported on the fingers 30 and 31 are advanced to the pointing and threading position by the operator graspin the lever22 and advancing said lever to t e position indicated in dotted lines Fig. 1, whereby the frame 17 is advanced, the guide-block 18 moving in the guides 16. NIn uthis manner the u per bolt is advanced into position, for pointing and the lower bolt is advanced in osition to be engaged by the threading dies. gust as soon as the threading dies take hold of /the lower bolt the rotating die-head will draw the bolt into the threading dies,
65 andconsequently the frame 17 will be adase 15so that as said` 'has not been illustrated ordescribed in dethe tension of the spring 52.`
.completed and the nut has been applied to the bolt, the threading dies are automativcally withdrawn and the bolt released. This automatic release of the bolt is a feature of these threading dies, and as stated above, the mechanism for performing this function tail. Just as soon as the threading dies withdraw and release the bolt, the s ring 25 comes into play and returns the rameV 17 to its normal position. On the return the frame 17 the trip-finger 39 asses up over the awl 40 and 1n th1s\way t e rockershaft 36 1s rocked and the rod 34 is elevated. This elevation of the rod 34 acts through the connections described to move the fingers 30 and 31 out of the runway 27, so that the bolt just pointed and the bolt threaded arefree to drop, the latter dropping down on to the chute 60, while theI former drops down into the position to'be detained by the detents 37, as clearly indicated in Fig. =3. The. upward movement of the rod 34 also moves the dogs 45 into the position indicated in Fig.- 3, whereby the lowermost of the bolts inthe magazine 29 enter the grooves 51 inl said dogs, and are retained in this position. When, however, the trip-finger 39 passes beyond the pawl 40 the spring 38 will lower the rod V34 and the lowering of the rod will act through the connections described to brmg the fingers 30 and 31 again into position to support the bolt just pointed land the one just released from the magazine by the movement of the dogs 45 which discharge the next bolt to be pointed on to the fingers 30 for the pointing operation. In 110 this manner the bolts are automatically delivered to the pointing and threading position in successlon while the blank bolts are fed one by one to the. runway to be operated on in succession.
In this manner, I avoid the manual labor heretofore required in removing the bolt from the pointer and feeding yit to the threading and nutting apparatus and thereby greatly increase the capacity and output.
In Fig. 4 I have illustrated a( modified form of my invention in which the applying of the nuts to the bolts is made a Separate operation where the combined threading and nutting device is not employed. modification only necessitates a third -set of fingers to support the bolt at the lowermost position for applying the nuts. Otherwise the construction and operation is the same and it has not been deemed neces- This 12s sary to refer yspecifically to the different parts of the modified structure except to designate the lower set of fingers to support the bolts in position for applying the nuts by the numeral 61.
