object of the invention is to provide a this character Which will notify e operator of the conditions ot the roving so thit he may correct the difiiculty. A numl r ie of 'lerices' have been devised for this purpose be they have many detects. F or inst on elerni is mode to sound when U roving breaks it will not sound when the rovin becomes bunched under the rollers,

brol'en. I it is the object of my invention to obviate these ditliculties, and broadly speaking to provide an alarm which Will be actuated by any abnormal condition of the roving, such its a too line or too thin roving owing to the neglect on the part of the operator to fill the feed box, or to notify the operator it the comb belt br aks or slips off, which causes choking up of the machine.

With these and other objects in view, the invention consists of certain novel features or construction, combination and arrangement of parts, as will be more fully described and particularly pointed out in the appended claims.

relatively long teeth so that when the unper roller is raised by the roving th' l) and it) will not be separated or dish guged. The inner pintlc of the roller (1 extended so as to enter a terminal ho); curried upon the adjustable bloc is slotted at 13, to receive the adjusting s :rcu' is, passing throu; l the block into the b i As shown in iig. 3 X emplo a pair euit terminals 15 and 1G, whi'h are Within the terminal be:

The spring ire closc togethe n p so as to pr the passage or the iintle lthout contacting With both of them. lVht-n the roving is of normal size and runso hing freely through the rollers the contacting end of the pinlle i7 is raised su'liicien h from the lower part of the terminals 15 e1 l6, so as to prevent engagement therew' if the roving brcelrs or becomes thin l reef son of the operator failing to fill the so if box the top roller will drop down and contacting end or the pintle 17 will on the contacts at their lowest part with tery B. it the roving becomes bunch the machine becomes cholreo. the roller 6 will rise owing to the excess amount of mate i traveling betvlzeen the rollers 6 and 7 cause the contacting end of the pintle 1! engage the upper member of the and close the circuit of the alarm operating the adjusting screw 1% seen that any suitable adjustnien. made.

It will be seen that as the en the roller 6 is the heavier, th= is risehigher at its pint'ie end when the roving, and thereby bring the engagement with the contacts. roving becozn s thin or breaks and the roller to drop, the pinion on the roller 6 has its in engagement w ie tcctii I if groove between the D11 or n and therefore cannot op terther. .ihe end herring the gamete l therefore permitted to drop into engagement with the contacts and thus close the circuit. From the foregoing description, taken in connection with the accompanying drawand the minor details of construction may be 5 resorted to without departing from the principle or sacrificing any of the advantages of this invention as defined in the appended claims.

llaving thus described my invention, what l claim and desire to secure by Letters Patv cnt is:-

l. A deviceof the class described, the combination with a frame, of a pair of roving rollers revolubly mounted therein, one oil which is adapted to move to tlltl and from the other roll in accordance with changes in the size of the roving. a terminal box cari l l t ried by said frame adjacent said rollers. a

pair of terminals therein, an electrical alarm circuit including said terminals, means for adpisting'the terminals w1th respect to the rollers, and means 0: rried by the movable t roller for bridging, the terminals in the extreme movement thereof in either direction.

2. A rm'ing alarm, comprising a vertically movable roving roller, :1 contact carried thcrel v. an electric circuit, and a single pair of terminals arranged on either side of said contact and adapted to be bridged by the moving contact in the extreme movement of said roller in either direction.

it. i\ roving alarm comprising a vertically movable rotary roller, an electric alarm circult, a pair of separated terminals therein,

and a contacting device lying between said terminals but normally out of engagement therewith, said contacting device being controlled by said roller and adapted to engage said itl'll'lllltllH in the extreme movement of said roller in either directioi'i.

In testimony whereof I have hereunto set my hand in presence of two subscribing Witncs-ses.
